According to a 2014 meta-analysis, probiotics benefit diabetics by improving insulin sensitivity and decreasing the autoimmune response found in diabetes. The authors suggest that the results were significant enough to conduct large, randomized, controlled trials (the “gold standard” of scientific studies) to find if probiotics may actually be used to prevent or manage diabetes symptoms. Combining probiotics with prebiotics may also help manage blood sugar, particularly when blood sugar levels are already elevated. (87)
DNA-testing matches identity at a foundational, genetic level, so you know you’re getting the exact strains listed. New Chapter’s DNA-testing also verifies that you receive the specific strains researched for specific benefits: our strains boost immune defenses and enhance digestion, including bowel regularity and reducing occasional gas, bloating, diarrhea & constipation.*
A large analysis reviewed available research and determined that probiotics help lower blood pressure by improving lipid profiles, reducing insulin resistance, regulating renin levels (a protein and enzyme secreted by the kidneys to lower blood pressure) and activating antioxidants. Researchers consider them valuable prospects in the treatment of high blood pressure because their side effects are generally minimal or nonexistent. (82, 83)

We’ll start with the headliner: the BIO-tract peral, which packs the equivalent of 75 billion CFUs into one tiny, filler-free, 5-billion CFUs pearl. The trick is in protecting those 5 billion CFUs over an 8 to 10-hour period, so they bypass your acidic stomach and reach your intestinal tract, alive and well, allowing you to experience the full and multitudinous benefits of plentiful and beneficial gut bacteria.
On my recent trip to Japan, one thing I noticed was the inclusion of pickled vegetables in almost every traditional Japanese meal. Unfortunately, many Americans don’t consume enough of these probiotic-rich foods and drinks. Even when they do, restoring equilibrium oftentimes requires therapeutic doses of these microorganisms, because most everyone has been on several rounds of antimicrobials. That’s where a probiotic supplement comes in.
Many Lactobacillus and Bifidobacterium species are naturals at protecting and improving gut health. Additionally, research in animals and humans has shown that probiotics decrease scores on depression assessments, thereby alleviating depression. As a matter of fact, there is a new term, psychobiotics, for these microbes that influence mental health conditions like depression.
Hi Julia. I am 71 (male) and have had digestive issues for most of my life and no specific diagnosis. I eat fairly well, am not overweight, get gassy from many different foods and beverages. I have been using Culturelle for 9 months and feel the benefit from taking it is small. Your review leads me to believe there may be better choices. They certainly are not cheap but I will gladly pay for them if they give me results. I am probably going to try BlueBiotics unless you have other suggestions. My main question is since I live in Minnesota I will receive shipments in the summer with temps of up to + 100F and winters down to – 15F. Will this cause a decrease in product viability for this or other brands you recommended? Thank you for your help.

The science on what probiotics do is still emerging. There is some hard evidence that suggests eating probiotic foods and supplements can have a beneficial effect on health. Other evidence suggests probiotics benefits are limited to those individuals in good health and should be avoided by those who suffer from certain serious health conditions. There is no research that demonstrates the risks or the benefits of probiotic supplements on children.


“Microbiome” refers to the trillions of bacteria and microorganisms that live on and in our individual bodies. “There’s increased recognition of the various ways that the microbiome affects our health,” Lebwohl tells me. “And with that recognition comes the true observation that many bacteria are good for us. This goes against the old idea that bacteria equal germs, which equal harm. It turns out that many bacteria keep us healthy and probiotics could potentially support that notion.”
Since the bulk of your natural flora exists in your gut, it makes sense that this is the part of your body that feels it most when bacteria become imbalanced. Women, in particular, can experience all kinds of digestive problems, particularly during hormone fluctuations. These are just some of the digestive symptoms a high-quality probiotic can help reduce and even treat:

Unfortunately, the U.S. has no federal standards for probiotic supplements. Therefore, you run the risk of purchasing a product without any guarantee that it contains its advertised probiotic strains, that the strains are alive, or that the product is free from unhealthy ingredients. Therefore, it may be best to choose a brand-name probiotic that has research backing their effectiveness. Here are some examples:


Probiotics stick around for a while, though for how long isn’t precisely clear. You have to keep taking them to continue to reap the benefits. Further, getting a wide variety of strains into your system is beneficial. “Periodically mixing up your probiotic supplement is also a good way to ensure that you get different health-building strains in your health regime,” says Dr. Cook.
Garden of Life RAW Probiotics are some of the most popular out there – and for good reason. Let’s start with the basics: You’ll get 85 billion CFUs and 31 to 33 probiotic strains out of your daily, whole-food, gluten-free, soy-free probiotic, which helps support the immune system, a healthy thyroid, nutrient absorption, digestive function, and a healthy microbial balance.
Women’s health expert Dr. Amy Myers is a goop-trusted authority on subjects from autoimmunity and Candida to thyroid dysfunction; and she’ll be speaking IRL at our first wellness summit on June 10. Here, Myers helps us evaluate the increasing buzz around probiotics, and outlines the ins and outs of selecting a particular supplement (whether hers or other brands). Plus, we’ve rounded up our probiotic essentials, from inner beauty powders to favorite fermentation recipes, in one guide:
The National Center for Complementary and Integrative Health (NCCIH) calls probiotics “live microorganisms (in most cases, bacteria) that are similar to beneficial microorganisms found in the human gut.” The NCCIH makes the point that we often think of bacteria as harmful “germs” — however, probiotic bacteria actually helps the body function properly.
Suez and colleagues investigated the recovery of the gut microbiota after antibiotic treatment and found that probiotics might perturb rather than aid this process. The probiotics rapidly colonised the gut but prevented the normal microbiota from repopulating for up to 5 months. While likely to be considerably less appealing, the group who received autologous faecal microbiota transplantation recovered their microbiota the quickest, with the composition of the microbiota returning to normal within days. Furthermore, Zmora and colleagues showed that colonisation occurred in highly individualised patterns, with some people's gastrointestinal tracts rejecting probiotics and others allowing colonisation by the probiotic strain, meaning that many individuals taking probiotic supplements are simply wasting their money.
Sugar is so easily accessible in Westernized cultures that it is easy to overindulge in it. But why do you crave it? There are several reasons. One, sugar usually means sucrose, which is composed of glucose and fructose. Glucose is the sugar in your blood, so consumption of sugar results in a temporary boost of energy. However, that blood-sugar spike causes insulin to be released to usher the sugar into cells for energy or fat storage, and shortly afterward your blood sugar drops. So then you feel a slump and reach for something to bring your blood sugar back up: more sugar.
I didn’t know there was much of a difference between probiotics until I did some research. After realizing the ones I had been getting were probably not doing anything for me, I wanted to invest in a better option. This brand checked all the boxes and was still really affordable! I’ve been taking them for about a week now and I can tell a difference! The first few days I didn’t feel too great but realized it was because this probiotic was actually doing something for me and rebalancing my gut. Now I feel less bloated and all around healthier. I will definitely be getting more! 

Historically, people had plenty of probiotics in their diets from eating fresh foods from good soil and by fermenting foods to keep them from spoiling. Over a century ago, the Russian Nobel Prize winner Elie Metchnikoff theorized that “health could be enhanced and senility delayed by manipulating the intestinal microbiome with host-friendly bacteria found in yogurt.” Metchnikoff was ahead of his time with his view of probiotics benefits, but he also was aware that most citizens had regular access to probiotic foods.
According to a 2014 meta-analysis, probiotics benefit diabetics by improving insulin sensitivity and decreasing the autoimmune response found in diabetes. The authors suggest that the results were significant enough to conduct large, randomized, controlled trials (the “gold standard” of scientific studies) to find if probiotics may actually be used to prevent or manage diabetes symptoms. Combining probiotics with prebiotics may also help manage blood sugar, particularly when blood sugar levels are already elevated. (87)
One thing that is often overlooked is gut health and the benefits of probiotics for weight loss. Gut microbiota can affect food intake choices, appetite, and body weight and composition. Dysbiosis, an imbalance in the gut microbiota with a shift favoring pathogens and opportunists, is common in overweight people. The pathogens and opportunists create an inflammatory situation that affects insulin and other hormones, resulting in the inability to lose weight.

The root of the word probiotic comes from the Greek word pro, meaning "promoting," and biotic, meaning "life." The discovery of probiotics came about in the early 20th century, when Elie Metchnikoff, known as the "father of probiotics," had observed that rural dwellers in Bulgaria lived to very old ages despite extreme poverty and harsh climate. He theorized that health could be enhanced and senility delayed by manipulating the intestinal microbiome with host-friendly bacteria found in sour milk. Since then, research has continued to support his findings along with suggesting even more benefits.

Some studies suggest that certain probiotic strains may also help in mild to moderate ulcerative colitis and possibly for bloating and gas in irritable bowel syndrome (IBS). Probiotic supplements, on the whole, “improve global symptoms, bloating, and flatulence in IBS,” by modifying the gut microbiome, according to a 2014 monograph from the American College of Gastroenterology. As IBS researchers said in a paper in Gastroenterology & Hepatology in 2015, “The concept of manipulating the microbiome is one of the most promising new ways in which to treat patients with IBS, but there is still much to learn.”
​​​​​​AZO Complete Feminine BalanceTM is a daily probiotic supplement designed for the unique needs of women. Many everyday things can throw off your balance (stress, sex, pregnancy, aging, even medications! This product supports your feminine health and maintain a healthy pH so that you can own your day! It contains INTELLIFLORATM: a probiotic blend of four lactobacilli that are associated with vaginal health* (Lactobacillus crispatus LBV 88, Lactobacillus rhamnosus LBV 96, Lactobacillus jensenii LBV 116, and Lactobacillus gasseri LBV 150.)  The INTELLIFLORATM blend has been shown in clinical studies to help restore and maintain the healthy balance of the vaginal microbiota.*

The second Elinav study, “Post-Antibiotic Gut Mucosal Microbiome Reconstitution Is Impaired by Probiotics and Improved by Autologous FMT” involved a mouse model and human patients. One cohort of mice and a parallel human group was given the same probiotic strain used in the first study to see if they had more success repopulating their gut microbiota after a round of antibiotics. Another “watch-and-wait” cohort didn’t take probiotics to assist gut microbiome recovery after antibiotic-related depletion. A third cohort was given an “autologous fecal microbiome transplant” (aFMT) which consisted of a patient’s own gut microbiota that had been collected before he or she started a cycle of antibiotics.

But before you start reaching for the calcium supplements, there may be a more effective way to support your bone health. Like many other parts of the body, the health of your bones is closely tied to the health of your gut, especially your intestines. Temporary intestinal inflammation can trigger an immune response in which your body releases interleukins, proteins that have an immune function but also absorb bone tissue. If the temporary inflammation remains unaddressed, these molecules can take a toll on your bones, eventually weakening them.14
If you suffer from a food allergy or intolerance, make sure to check those labels! Probiotics with these dietary features often say so right on the front of the bottle, but you will also want to take a quick peek at the ingredients list as well. A word to the wise: anyone with a food allergy should also check the manufacturer’s information to ensure that cross-contamination is not likely to have occurred on-site in the packaging facility.

Called probiotics, these good bacteria help break down food, synthesize vitamins, prevent bacteria that cause illness from getting a foothold, and bolster immunity. Some studies suggest that as we get older, the number and variety of good bacteria in our bodies decline. So taking probiotic supplements to replenish them might seem like a no-brainer.
If you’ve ever experienced the crippling pain of a urinary tract infection, you’ve probably encountered an article or two about the benefits of cranberries for warding off bacteria in the urinary tract. While it may seem like an old wives tale, cranberries contain D-Mannose that is naturally acidic. This compound has been said to prevent unwanted bacteria build-up, and some claim it can even stop a urinary tract infection dead in its tracks!
Helicobacter pylori (H. pylori) is a bacteria that causes chronic inflammation (gastritis) of the inner lining of the stomach, and also is the most common cause of ulcers worldwide. About 50% of people in the world carries or is infected with H. pylori. Common symptoms of H. pylori infection are occasional abdominal discomfort, bloating, belching or burping, and nausea and vomiting. H. pylori infection is difficult to erdicate, and treatment is with two or more antibiotics.

Probiotics: Health benefits, facts, and research Every human on the planet has microbes living in their body. While bacteria get a bad reputation, many can promote good health. Probiotics are a type of 'good bacteria' that provide health benefits for the host. The health benefits of probiotics include treatment of diarrhea and irritable bowel syndrome. Read now
Until recently, testing of probiotics by ConsumerLab.com found that some products had far lower amounts of live organisms than claimed on the labels. But in 2018, it found that 17 out of 18 products tested contained the amounts listed; none exceeded limits for heavy metal contaminants. In contrast, in 2016, a study in Pediatric Research found that only one out of 16 Bifidobacterium longum supplements tested contained the species named on the label.
As of now, the most comprehensive meta-study (a study of different studies) has not been able to decisively identify any particular strain of bacteria that is specifically useful to treat seasonal allergies. Some studies contradict each other on which bacteria can treat grass pollen, and other studies will find that those strains the first two studies examined weren’t nearly as effective in their own trials.
The high quality supplement comes in veggie capsule form, and no refrigeration is necessary. This probiotic is made in an FDA registered facility (in the US), and it meets GMP standards. It’s an all natural supplement, that’s free of lactose, soy and gluten. It also contains no artificial coloring. DNA Shift probiotic also offers prebiotic fiber for an extra healthy brain and gut.
Bacillus is an interesting genus because these microbes have the ability to form endospores, tough outer coatings, when conditions are not suitable for them to flourish. There are five species of probiotic Bacillus: clausii, coagulans, indicus, licheniformis, and subtilis. Not every species of Bacillus is probiotic. Some Bacillus species are usually pathogens. Bacillus may normally be found in the GI tract, but they generally do not take up residence for long and will pass through and be eliminated if not replenished. Bacillus are common food spoilage organisms and are also found in probiotic supplements and in soil, air, and water.
"The name itself is derived from the Latin 'pro-' meaning 'for' and the Greek '-biotic' meaning 'life,'" explains Jeannel Astarita, skincare expert and founder of Just Ageless NYC Wellness and Medspa. "Probiotics are the helpful bacteria that live primarily in your gut and play a crucial role in your overall health by fighting pathogens and yeast that lead to a weakened immune system."
But what if investigators could design probiotics to treat specific individuals? Many researchers think personalized probiotics are the most promising path forward for patients with compromised gut microbiomes. Last year Jens Walter of the University of Alberta and his colleagues published a study that gives a glimpse of this potential future. The researchers decided to see what it would take to get the bacteria in a probiotic to successfully colonize the intestines of 23 volunteers. They chose a particular strain of Bifidobacterium longum that earlier studies had indicated could survive in the human intestine. In the study, the volunteers consumed either a drink containing 10 billion live B. longum bacteria or a placebo in the form of a glucose-based food additive (maltodextrin) each day for two weeks. Periodic fecal samples revealed higher than typical levels of B. longum in participants who did not consume the placebo.

In addition to its powerful probiotic strands, the Vitamin Bounty Women’s Pro-Daily Probiotic also features a proprietary women’s health formula. This blend includes many of the minerals and plant extracts that have been found to be the most beneficial to women’s health, making it ideal for any women that have experienced feminine health problems. Specifically, this Vitamin Bounty formula includes Ashwagandha Root Powder, Cranberry Fruit Powder and Black Cohosh Root Powder.
Probiotics stick around for a while, though for how long isn’t precisely clear. You have to keep taking them to continue to reap the benefits. Further, getting a wide variety of strains into your system is beneficial. “Periodically mixing up your probiotic supplement is also a good way to ensure that you get different health-building strains in your health regime,” says Dr. Cook.
The bottom line: Stick to trusted whole food sources of probiotics if you don’t know a probiotic supplement brand you trust. “Kimchi, pickled beets, Greek yogurt and sauerkraut are great sources of probiotics. If you don’t like them, throw them into a food you do like, like a smoothie, and add your favorite fruit to help mask the flavor,” Taub-Dix says.

Clinically shown to work in 7 days§, AZO Complete Feminine BalanceTM works differently because it contains the power of INTELLIFLORA,TM the only clinically proven blend with the 4 vaginal lactobacilli species most commonly found in healthy women.* Specially designed to restore the vagina’s microflora, it’s a safe and beneficial probiotic for women’s health—including pregnant women.*§ Add it to your daily regimen for help with protection and ongoing vaginal health support.*


If you’re giving probiotics to a baby under two years old, you want to look for specific strains, though, that are better suited to such young microbiomes. For babies, these are the strains of Lactobacillus to look for: rhamnosus, casei, paralisei, gasseri, salvarius. And for Bifidobacterium: infantis, bifidum, longum, breve, lactis. If you’re breastfeeding, you can put probiotics on your breast, or you can heat up formula and put probiotics in it, or wet your finger and dip it in the probiotics powder and let your baby suck on your finger.
This makes it harder for your immune system to work properly and leaves you open to feeling under the weather unnecessarily. The good news is that taking probiotics can help replenish your gut microbiome, and since 80% of your immune system is in your gut, this inevitably has a very supportive effect on your immunity. Probiotics also specifically support your mucosal immune systems, found in your ear, nose, and throat area and your lungs, helping you to maintain respiratory health.4
Many avenues of research have examined probiotics benefits for skin, especially in children. Meta-analyses have found that probiotic supplements are effective in the prevention of pediatric atopic dermatitis and infant eczema. The integrity of gut bacteria is also connected to the development of acne, although the way this happens is still unclear.
Other uses. Many other claims are made for probiotics—that they lower cholesterol, alleviate allergic skin conditions (like eczema), treat ulcers and urinary tract infections, improve vaginal health, reduce the risk of colon cancer, ease anxiety and depression, and ward off traveler’s diarrhea. Good evidence to support these claims is lacking. Research on probiotics for weight loss has yielded inconsistent results, and even studies with positive results have mostly found very small benefits, as was seen in an analysis of 15 clinical trials in Obesity Reviews in 2018.
If you want to take advantage of the benefits of probiotics and you also want to make sure the beneficial bacteria you already have is optimized to its full potential, supplement your probiotic regimen with Prebiotin. A trained microbiologist cannot tell you which probiotics are the best ones to choose, so why try to do something you are not trained to do? Eat lots of foods with prebiotics in them and take a prebiotic supplement like Prebiotin. It’s the best thing you can do to maximize the benefits of both prebiotics and probiotics on the bacteria in your gut, and your overall good gut health.

After further analyzing the data, the researchers found that they could predict whether the probiotics would take hold in people's guts by examining their microbiome and gene expression in the gut taken at the start of the study. However, this prediction method needs to be confirmed in future studies. The researchers called for further research to better understand why some people resist colonization by probiotics, as that future research may enable researchers to counteract the resistance.
Selecting a multi-strain probiotic is also consistent with the theory that filling your gut with enough good bacteria outcompetes any bad bacteria for the same space and resources. In your gut, the more diversified the good bacteria, the harder it is for the baddies to gain a foothold. With all this in mind, we only looked at supplements containing multiple strains of bacteria.
If you’re new to Bio-K+, know that each bottle contains 50 billion live and active probiotic bacteria. Probiotics are good for a wide variety of digestive issues, so it’s best to customize your dosage based on what your specific needs are. If you are looking to take a preventative dosage to support the health of your microbiome, start with a ¼ bottle per day. If you suffer from digestive health issues or regularly take antacids, start with a ½ bottle of Bio-K+ per day. If you have more serious gastrointestinal issues or have had to take antibiotics, Bio-K+ probiotics are great for getting your system back on track. Start with a full bottle per day and see how you feel (we’ve had amazing results from our fans!)
The bad news about constipation is that there can be many causes, from simple causes like dehydration and lack of fiber to complicated structural causes or disease. While constipation may seem to be only a nuisance that causes uncomfortable symptoms such as abdominal bloating or pain, the truth is that constipation increases the risks of several diseases.
Bacillus is an interesting genus because these microbes have the ability to form endospores, tough outer coatings, when conditions are not suitable for them to flourish. There are five species of probiotic Bacillus: clausii, coagulans, indicus, licheniformis, and subtilis. Not every species of Bacillus is probiotic. Some Bacillus species are usually pathogens. Bacillus may normally be found in the GI tract, but they generally do not take up residence for long and will pass through and be eliminated if not replenished. Bacillus are common food spoilage organisms and are also found in probiotic supplements and in soil, air, and water.

Antibiotics are also a major contributor to gut imbalances. Many of us have been overprescribed antibiotics by well-meaning, conventional doctors from childhood onward. Antibiotic use as a solution for every infection is ingrained in our culture. Every time you take an antibiotic throughout your life, you disrupt your gut flora for up to 12 months.


The National Center for Complementary and Integrative Health (NCCIH) calls probiotics “live microorganisms (in most cases, bacteria) that are similar to beneficial microorganisms found in the human gut.” The NCCIH makes the point that we often think of bacteria as harmful “germs” — however, probiotic bacteria actually helps the body function properly.
This Korean staple relies on lactic acid fermentation (also called lacto-fermentation) to turn cabbage or other vegetables into a spicy, pungent side dish that's packed with vitamin C. Order it at Korean restaurants or buy it in the refrigerated section of your grocery store (King's Kimchi is widely available at Walmart). For some guidance on making your own, turn to The Art of Fermentation ($23; amazon.com). Then, use it to spike veggie-laden rice bowls, top on soup, or serve alongside meat.
Overall, I really like TruBiotics as a daily probiotic. First of all, the capsules are easy to take and you only need one a day. I also like the choice of strains they used in this probiotic. Overall, TruBiotics is a great daily probiotic that’s quick and convenient and may be very effective with regards to many different digestive issues.   Read the full review here… or click here to go buy it now!
The current probiotic push lends itself to the question, "If humans got along fine without taking a probiotic supplement for thousands of years, why are they so important now?" Although there is no definitive answer to this question, there have been some significant cultural changes that have had an impact on the gut flora (the population of organisms that populate our intestines). These include the use of antibiotics, diets lacking in gut-healthy plant food, refrigeration and improved sterilization of foods. What we don't yet know is true is if probiotics actually turn around these changes and support the health of your gut flora.
For example, yogurt is made with two “starter” bacterial cultures — Streptococcus thermophilus and Lactobacillus bulgaricus — but these bacteria are often destroyed by your stomach acid and provide no beneficial effect, Dr. Cresci explains. Some companies, though, add extra bacteria into the product, so check the labeling and choose products with bacteria added to the starter cultures, she advises.
“I’d probably stay away from store brands and pay a little extra for the name brand that’s been studied,” Dr. Cresci adds. “Ideally, look for a product that’s been tested for whatever you’re looking to address. It might say it helps with IBS, but you wouldn’t take that same product if you were taking antibiotics. You would want a product that helps with immunity. That’s where a lot of people get confused.”
EDITOR’S CHOICE: As the only probiotic formula we reviewed backed by a New York Times Bestselling author and expert in the human biome, the Garden of Life Dr. Formulated Once Daily Women’s Probiotic is our top choice for overall digestive and women’s health. With 50 billion cultures and 16 probiotic strains, this probiotic helps to promote women’s digestive, immune and vaginal health.
Additionally, it's a good idea to take note of the number of colony-forming units (CFUs) that are in the supplement you're considering, Angelone says. CFU count tells you the number of viable, active bacteria present in a tablet, she explains, and one billion (yes, seriously) is a typical dose. However, if you're struggling with a specific health condition, you may need more than that, Warren says. Your doctor can help you decide whether that's the case and may be able to steer you toward a good supplement to get you started. Here are a few to consider if you decide that probiotics are right for you.
We are clearly getting to the strain level by going beyond “Saccharomyces boulardii” and to “Saccharomyces boulardii CNCM I-745”. They did a great job by actually putting it on the label so you don’t even have to contact the company to see exactly what strain you’re getting. (P.S. this is a well-researched strain that I highly recommend, especially for preventing antibiotic-associated diarrhea.)
The idea that bacteria are beneficial can be tough to understand. We take antibiotics to kill harmful bacterial infections and use antibacterial soaps and lotions more than ever. The wrong bacteria in the wrong place can cause problems, but the right bacteria in the right place can have benefits. This is where probiotics come in. Probiotics are live microorganisms that may be able to help prevent and treat some illnesses. Promoting a healthy digestive tract and a healthy immune system are their most widely studied benefits at this time. These are also commonly known as friendly, good, or healthy bacteria. Probiotics can be supplied through foods, beverages, and dietary supplements.

Some people prefer probiotic supplements over foods, but Dr. Cresci notes that probiotic foods are a better choice. In particular, fermented foods — like yogurt, kefir (a yogurt-like beverage), kombucha (fermented black tea), sauerkraut (refrigerated, not shelf-stable), kimchi (made from fermented cabbage) and tempeh and miso (made from fermented soybeans) — provide a nourishing environment in which healthful bacteria thrive and release an important byproduct: short-chain fatty acids.
Proponents claim that probiotics (meaning “for life,” as opposed to antibiotics) confer health benefits primarily by rebalancing the normal microflora in the large intestine (colon). There are many general types of bacteria used as probiotics (two common ones are Lactobacillus and Bifidobacterium), and many different species as well as strains within species. They have different physiological effects—and thus possibly different health benefits (as well as possible risks). Some yeasts, such as Saccharmyces, can also act as probiotics.
Survival past stomach acids - probiotic powder in capsule form is ill prepared when it comes to protecting the delicate bacteria from being pulverized by the harsh environment of the stomach acids. Worse, most of the organisms tend to die off before they reach their intended destination due to moisture that gets trapped between the capsule shell and the powder.
Make sure to keep them away from moisture and heat which can kill off some of the microbes. I recommend taking on an empty stomach, ideally right when you wake up. You should always store supplements in a cool, dark place but refrigeration is best. Most of the strains of probiotics are fragile and should be protected from heat- so refrigeration is ideal. I recommend the probiotic Gut Instinct from HUM Nutrition for transparency and high quality.
"I usually recommend Garden of Life, BioK or Megafoods brand," says Shapiro. "I also recommend starting with about 30 billion CFU and making sure your supplement has at least 12 different strains. And if you don't eat a diet high in fruits, vegetables, nuts, seeds, and whole grains that provide fiber for the probiotics to live off of, make sure you're the one you are taking contains prebiotics as well.
Topping the probiotic market numbers at 100 Billion CFU divided between 34 probiotic strains, Garden of Life’s Ultimate Care probiotic was definitely a contender for our Best Probiotic of 2018. Free from preservatives and additives, RAW scored impressive marks across the board. Although this shortens the lifespan of the probiotics strains somewhat, buying in small quantities can easily solve this problem and – honestly – at CHR we always prefer purity to additives.

"This suggests that probiotics should not be universally given as a 'one-size-fits-all' supplement," study co-senior author Eran Elinav, an immunologist at the Weizmann Institute of Science in Israel, said in a statement. However, it may be possible to tailor probiotic treatments to the individual, based on the types of microbes already in his or her gut, as well as other factors, so that he or she gets the most benefit from probiotics, the researchers said.


I did the “milk test” on these New Rythm probiotics, along with Culturelle I had purchased in 2 different states (TX & MA, as I was traveling); my mother’s CVS brand acidophilus; and one “control” cup with milk only (so, 5 cups total in my experiment). The New Rythm became a solid yogurt consistency, while the other 4 remained liquids. I did the experiment twice, just to be sure of the results. I could not believe it!!! New Rhythm is my brand, hands down!!! I also would like to mention that my product usually arrives the day after it ships. So it will take a few days to ship when I select standard shipping, which is to be expected, but it doesn’t stay in transit long which is ideal for preserving the living cultures.
To boost the immune system, B. Lactis is a promising choice. One study had participants taking either a probiotic or a placebo for 6 weeks. At the end of the period, researchers measured antibody levels and found greater increases in antibodies of the B. Lactis group than in placebo participants, concluding that this probiotic may help improve immune function [1]. In addition, a 2009 study found that supplementation of the strain B. Lactis DN-173 led to self-reported improvements in digestive comfort [2].
If you get sick often, probiotics might be the immune booster you've been looking for. The Cleveland Clinic says they've been shown to strengthen immunity by enriching and replenishing the good bacteria in the body. And when you eat foods with probiotics regularly, it's easier for your body to produce vitamins and enzymes that help keep your intestines happy.
