Method of delivery: "The probiotic needs to be able to survive the acidic environment of the stomach and reach the intestine," explains Dr. Nazareth. This can be optimized through the way you take the probiotic and what's included in the formula. "Some delivery systems to consider are time-released tablet/caplet, capsules with an enteric coating and/or microcapsules, and ones that contain prebiotics and the optimal combination of probiotics," says Lori Chang, a registered dietitian with Kaiser Permanente in West Los Angeles.

Some yogurts contain the aforementioned bacteria; however, because they are sensitive to oxygen, light, and dramatic temperature changes, make sure to look for yogurts with “live and active cultures.” Many commercial yogurts are heat-treated or pasteurized, resulting in the loss of these valuable cultures. Learn more about the smart way to shop for probiotics.
Bacteria in your digestive tract can be good or bad, according to the website Best Probiotic. It quotes the Royal Academy of Medicine England as blaming an imbalance between good and bad bacteria for causing 80 percent of all degenerative diseases. Probiotic supplements with "good" bacteria have become increasingly popular. They can aid the immune system, digestion and vitamin absorption, as well as prevent diarrhea and irritable bowel syndrome. The website Women to Women recommends probiotics that combine saccharomyces, lactobacillus acidophilus and bifidobacteria in the billions. MayoClinic.com also recommends lactobacillus and advises looking for products that contain live, active cultures. You should always check with your doctor before adding any supplements to your diet.
In these cases, IBS is essentially just TMI. “For the colon to be functioning properly, it needs to be contracting and relaxing in a way that is conducive to regular bowel movements that occur at predictable times and don’t occur too frequently or too rarely," Lebwohl says. "And the bowel needs to be giving infrequent feedback to the brain. People should not be getting updates from their bowel in terms of cramps or the feeling of having to have a bowel movement too often. Yet, people with IBS get very frequent unsolicited ‘progress reports’ from the bowel.”

Popular probiotic foods include yogurt, kimchi, sauerkraut, and kombucha. While delicious, these foods don’t claim specific amounts of whatever microorganisms they may contain. By contrast, Probiotic All-Flora is optimally formulated with the right amounts of the right strains to deliver researched benefits. The label lists out the DNA-tested flora that make up that ideal 10 billion CFU in just one capsule daily. So probiotic supplements actually have more reliable strain benefits than probiotic foods.
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.

Although many manufacturers will make claims regarding the benefit of probiotics for all sorts of disorders, there is not always research to back up those claims. It can be difficult to conduct quality research on probiotics due to the wide variety of strains available. And many studies show mixed results. However, given that, there is some research support for the use of probiotics for the following health conditions:

The Strand Similar to multivitamins, not all probiotics are created equal. Different probioitcs have different bacteria strains with varying benefits; and some probiotics may contain more than one strain, so it’s important to do your research. Some strains may help with gastrointestinal issues like diarrhea, while others may not have any effect on the GI tract at all, according to Keri Gans, RDN, author of The Small Change Diet. If you’ve made the decision to take a probiotic supplement but you’re unsure about which strain to take, ask your doctor or a registered dietitian for a recommendation. “You most likely will not have any negative side effects from using the wrong strain, but you may also not see any benefits,” says Gans.
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)
Coming in at a close second, our runner-up as the best probiotic for women is the Culturelle Women’s Healthy Balance Probiotic. As the #1 recommended brand by pharmacists, it is easy to see why so many women are turning to Culturelle for their digestive health. Featuring the LGG culture and a laundry list of other healthy bacteria, this probiotic offers a wonderful balance between digestive and feminine health. The Culturelle Women’s Healthy Balance Probiotic is also taken in an easy, chewable tablet and can even be taken during pregnancy, making it one of the most versatile formulas we reviewed!
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.
The Golive Berry Probiotic and Prebiotic Supplement Blend is perfect for tossing in your bag or keeping in your desk. Each packet includes 15 billion CFUs and 15 different probiotic strains. It also has a soluble fiber prebiotic to promote the growth of good bacteria in your body. Each packet contains 30 calories and comes in five flavors including pomegranate, melon cucumber, citrus blueberry, and a flavorless option. It can be mixed in any hot or cold drink, but we recommend tossing the flavored packet into a bottle of water. You’ll get 10 packets in each order.
After suffering from liquid nighttime but painless diarrhea for over a year (which I semi-controlled with one Imodium/day), I had a colonoscopy that gave a diagnosis of microcolitis. After the colonoscopy, I developed for the first time excrutiatingly painful gas pain in the LLQ. Usually this pain started during aerobic activity such as walking, but not always. Sometimes I woke up with it. CT scan revealed nothing. Will a probiotic help and if so, which would be best? There are so many it is hard to choose.

Similar to yogurt, this fermented dairy product is a unique combination of milk and fermented kefir grains. Kefir has been consumed for well over 3,000 years, and the term kefir was started in Russia and Turkey and means “feeling good.” It is created by the fermentation of milk by the bacteria, and yeasts in kefir starter break down lactose in the milk — that’s why kefir may be suitable for those who are otherwise lactose-intolerant.
More and more evidence shows that the gut microbiota may play an important role in the development of obesity, obesity-associated inflammation and insulin resistance. Obesity and Type 2 diabetes are associated with changes in gut microbiota. Several studies describe differences between the microbiota of lean individuals and those who are obese. The potential for using probiotics in weight management and obesity and diabetes prevention is exciting.

There is also promising research on this species for supporting skin. Ceramides are natural lipids that make up the surface of the skin structure. Depleted ceramide levels are clinically linked with dry and damaged skin. S. Thermophilus was shown to have a beneficial effect on the level of ceramides in the barrier of the skin, which protects underlying tissue from infection, dehydration and chemicals. These skin-supporting microbes also act as antioxidants in the body, trapping reactive forms of oxygen that dry, damage and age the skin [1].
Best Probiotic says that Suprema Dophilus, manufactured and distributed by Vitabase, enjoys the highest customer rating in the market. Specially coated to help the bacteria spread through your entire digestive tract, its website claims over four billion viable cells per capsule, including five lactobacillus strains and three bifidobacteria cultures. Best Probiotic says that Suprema Dophilus also contains fructo-oligosaccarides to increase the life span of the bacteria.
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.
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.
What about prebiotics vs probiotics? Prebiotics are the food fibers that go through the gut unchanged and are then used by good colon bacteria as a food source for their own growth. Everyone already has most of these good bacteria present, but often in small quantities. Prebiotics are used to stimulate their growth. Simply stated, you already grow your own probiotics within your colon. You do not rely on them to make the passage through the stomach acid — acid that can destroy many probiotic bacteria. That’s why taking a probiotic supplement or adding probiotic foods to your diet does not always help your digestive system. You can eat as many probiotic bacteria as you want, but if they don’t survive the trip to the colon, your effort will be fruitless.

The research also showed that while probiotics colonised the gastrointestinal tract of some people, the gut microbiome of others just expelled them. There was no way of telling from their stool sample which category people fell into. “Some people accept probiotics in their gut, while others just pass them from one end to the other,” says Elinav. They found that the probiotic colonisation patterns were highly dependent on the individual. That tells us that the concept that everyone can benefit from a universal probiotic bought from the supermarket is empirically wrong, he says.

Among their numerous health benefits, research shows these friendly microorganisms help prevent bowel diseases, improve your immune system, reduce traveler’s diarrhea, help you maintain a healthy weight, heal various skin conditions, improve bloating and other uncomfortable GI symptoms, and even boost your mood, helping to reduce the effects of anxiety and depression.


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.
For Irritable Bowel Syndrome, patients who respond to a probiotic might take that in the long term, Lebwohl says, so as to maintain symptom control. With something like antibiotic-related diarrhea, you'd take it for a defined period of time until symptoms are gone. "This has been studied in children and adults and while study results have varied, meta-analyses suggest that probiotics can be protective in this context," he adds.
The beneficial microbes, including probiotics, live with other microbes that are either benign, pathogenic (disease-causing), or opportunistic, meaning that they normally play nicely but can get out of control if given the opportunity. Actually, any microbe can cause you problems if it ends up in a place other than where it is supposed to be. Such a scenario can happen with intestinal permeability, commonly called leaky gut. Leaky gut happens when the layer of skin-like cells in your GI tract develops gaps in between the cells, allowing food particles, toxins, microbes, and other hazards to enter your bloodstream, if not stopped by the immune system. Since mucus, the thin layer of cells, and your immune system are your only defenses against the outside world within your digestive tract, it is very beneficial to you to have helpful microbes protecting you from potentially pathogenic microbes. These beneficial microbes can produce acids or antimicrobial products called bacteriocins, which hinder or kill pathogens. They can also stand in solidarity to prevent pathogens from taking up residence, or displace them if they do.

“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.”
If you have an immune system problem or another serious health condition, you may have a greater chance of issues. Some reports have linked probiotics to serious infections and other side effects. The people most likely to have trouble are those with immune system problems, people who've had surgery, and others who are critically ill. Don't take probiotics if you have any of those issues.
Culturelle Probiotics, although very basic, is still a great probiotic supplement.  The results I got from trying it were positive– I felt pretty good throughout the entire trial period. Although this product only contains one strain of probiotic, the one they chose is a solid one.  The cell count is 10 billion, which is a good number for a daily probiotic.  Lastly, Culturelle doesn’t contain any frequently-irritating ingredients like milk, dairy or gluten.  Read the full review here… or click here to go buy it now!
Certain brands, like Attune (attunefoods.com; available at Whole Foods), have pumped up the dessert by adding probiotics. (Attune boasts 6.1 billion CFUs, or "colony forming units," a measure of live, active microorganisms per serving. As a comparison, some probiotic supplements may contain 1 to 50+ billion CFUs.) Sounds crazy, but it's backed by science. One study in the International Journal of Food Microbiology found that probiotics added to chocolate were able to reach the GI tract where they could get to work colonizing the gut with healthy bacteria.
This high-potency (25 billion CFU) supplement blends 12 different strains in a base of inulin. The Ther-Biotic Complete capsules are vegetarian (made from hydroxypropyl methylcellulose, water) and the formula is free of common allergens, such as milk, eggs, fish, tree nuts, peanuts, wheat, gluten, and soy so it’s perfect for those with allergies. There are 60 capsules per bottle.
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!
We have to give a nod to the most famous probiotic food: yogurt. Whether you love Greek or regular, low-fat or full-fat, look for the phrase "live active cultures" on the label. And although choosing a plain yogurt has less added sugar than the flavored kinds, Tallmadge gives you the okay to choose a fruit-infused flavor if that's the only way you'll eat it. Just be sure to aim for fewer than 15 grams of the sweet stuff per serving; sugar can feed the bad bugs in your gut.
To factor strain-specific benefits into our efficacy score, we referenced the information in these guides. Products were rewarded for containing strains on these lists. Additionally, measured levels of each strain were compared to what is thought to be effective based on these guides, and scores were scaled accordingly. In cases where products did not list strain-specific amounts, or their listed strains were not included in these guides, total measured CFUs were compared to a general effectiveness threshold of 1 billion CFUs cited by research published in the American Journal of Clinical Nutrition11.
