“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.”
The takeaway: Certain strains were found useful in preventing diarrhea among children being prescribed antibiotics. A 2013 review showed that after antibiotic use, probiotics help prevent Clostridium difficile-associated diarrhea. A review focused on acute infectious diarrhea found a benefit, again for certain strains of bacteria at controlled doses. There’s also evidence that they may help prevent necrotizing enterocolitis (a serious gastrointestinal condition) and death in preterm infants.

Following a healthy and active lifestyle and eating a balanced diet are the best ways to foster a bountiful gut flora. Taking care of your gut flora can help with things like irritable bowel syndrome and chronic constipation, among other things. Even if you’re not sold on pursuing probiotics for your allergies, they’re good to consider if you’re experiencing any gastrointestinal issues.
Most recently, two back-to-back papers were published simultaneously on September 6 in the journal Cell showing that many people can’t successfully colonize standard probiotic microbiome in their gut. The scientists also found that consuming generic probiotic strains after taking antibiotics often delayed gut bacteria and gene expression from returning to their natural "naïve" state.
Minerals And Extracts – Many probiotics, especially those marketed for women, also contain blends of vitamins, minerals, and plant extracts for optimal results. In some cases, these blends can be so inclusive that they actually replace your traditional multi-vitamin, and can be an excellent source of nutrition for women that don’t receive enough vitamins or nutrients in their basic diets.

Digestive Advantage is one of the better probiotics available today. With 2 billion live cells in each capsule, it makes for a good daily probiotic for digestive and immune health. This probiotic claims that it can survive in your digestive system up to 10x better than yogurt. If this fact holds true, taking a supplement like this is much quicker and possibly more efficient than eating spoonfuls of yogurt everyday!  Overall, Digestive Advantage succeeds in being a great probiotic that’s a great value and can be taken every day!  Read the full review here… or click here to go buy it now!

Pinning down the exact causes of IBS is difficult because each person has his or her own combination of causes. One cause that is receiving much attention is that of a disrupted microbiome, as there is a strong association between having a gastrointestinal (GI) infection, like food poisoning, and the onset of IBS. Also, the FODMAP diet, and nonabsorbable antibiotics to kill gut microbiota, have provided relief in many patients, further supporting the suspicion of a disrupted microbiome as contributing to IBS.


Made from aged, fermented soybeans, this paste is brimming with probiotics. You can buy miso paste in a bunch of varieties (white, yellow, red, brown) and the darker the color, the deeper the taste. Miso is a great way to add a burst of earthy, savory flavor for few calories (only 25 to 30 per tablespoon), plus protein, fiber, and bone-strengthening vitamin K, says Sharon Palmer, RDN, author of Plant-Powered for Life. "While we need more research about how these types of fermented foods contribute to health, it's a good idea to introduce more of them into your diet," she says. Use miso to glaze fish or chicken before cooking, mix into a stir-fry recipe, or add to liquid to make a miso broth. One caveat: Miso is very high in sodium. One teaspoon, enough to make a cup of miso soup, has 473 mg of sodium, 21% of the daily recommended limit and 32% of the daily limit for those with high blood pressure.
Immunity and colds/flu.There’s a close connection between the bacteria in your colon and the immune system. Several studies, including one in 2012 in the British Journal of Nutrition, have found that certain probiotic strains boost measures of immune response—but whether this translates into any clinical benefits is uncertain. Studies have been inconsistent, for example, as to whether probiotics will actually curb colds and other upper respiratory infections. In 2014 a review in the British Journal of Nutrition, which looked at 20 clinical trials, linked probiotics to shorter duration of colds, but not necessarily reduced incidence or severity. Similarly, a 2015 Cochrane review of 12 clinical trials concluded that certain probiotics may help prevent or shorten such infections, though the quality of the studies was poor.
They can break down substances in foods that keep you from absorbing the micronutrients inside. They not only protect against the consequences of rogue molecules passing through a leaky gut, but they assist your intestinal cells in staying healthy to optimize nutrient absorption. In addition, some of the metabolic by-products of probiotics, such as short-chain fatty acids and vitamin production, are very nourishing to your GI tract.
Although probiotics have been around since the early 1900s, they have recently gained popularity due to their ability to treat a wide range of ailments. Research also suggests that probiotics can help you lose weight and maintain a healthy body-mass index, according to a meta-analysis that reviewed 20 studies that was published in May 2016 in the International Journal of Food Sciences and Nutrition.
Because there's a huge variety of probiotic products available on the market, many people struggle to find the right one for them. "There are many different strains of bacteria in different combinations within different probiotic supplements," explains Brooke Scheller, a clinical and functional nutritionist. "For example, a probiotic may contain a single strain of bacteria or many. It may also contain other vitamins, minerals, or other ingredients that may tout health benefits," she says. There are many different dosages, delivery systems (powder, tablets, capsules), and formulations (refrigerated vs. shelf-stable), and some probiotics also contain prebiotics, which basically act as fertilizer for the probiotics.

Because poor gut health is related to autoimmune responses like those found in rheumatoid arthritis (RA), probiotics have been a proposed treatment option for the condition. Only a few studies have been conducted in humans, and only one testing L. casei 01, a particular probiotic strain, was able to find a decrease in RA inflammation and progression of the disease.
Probiotics are officially defined by the Joint Food and Agricultural Organization of the United Nations/World Health Organization Working Group as “Live microorganisms that, when administered in adequate amounts, confer a health benefit on the host.” Basically, probiotics at this point in time are live bacteria and yeasts that provide health benefits to you if you take them in adequate quantities.
Like other top probiotics available today, LEAN’s 50-Billion Probiotic is packaged in a handy, delayed-release capsule, designed to protect non-acid-resistant bacteria until they reach deep into your GI tract, where they’re most needed. The result is maximum effectiveness – better gut health, an immune boost, and relief of common digestive problems.
Walk into any grocery store, and you will likely find more than a few “probiotic” products brimming with so-called beneficial bacteria that are supposed to treat everything from constipation to obesity to depression. In addition to foods traditionally prepared with live bacterial cultures (such as yogurt and other fermented dairy products), consumers can now purchase probiotic capsules and pills, fruit juices, cereals, sausages, cookies, candy, granola bars and pet food. Indeed, the popularity of probiotics has grown so much in recent years that manufacturers have even added the microorganisms to cosmetics and mattresses.

Probiotics are live microorganisms that are thought to have health benefits, as the National Institutes of Health (NIH) reports. These bacteria and yeast are believed to help populate our guts with beneficial microbes, according to Mayo Clinic, and can be found in fermented or unpasteurized foods including yogurt, kefir, sauerkraut, and kimchi, as well as, yes, supplements.


Stability and organism types — Some probiotic strains need to be kept cold in order to preserve their potency. This applies to their production, transport, storage and sales. Others are shelf-stable and don’t require refrigeration. Unfortunately, most refrigerated probiotics never make it past the stomach because they aren’t stable. Instead, look for a shelf-stable product that contains soil-based organisms.
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)

Constipation is defined medically as fewer than three stools per week and severe constipation as less than one stool per week. Constipation usually is caused by the slow movement of stool through the colon. There are many causes of constipation including medications, poor bowel habits, low fiber diets, laxative abuse, and hormonal disorders, and diseases primarily of other parts of the body that also affect the colon.
Before buying this, I didn't realize that some strains of bacteria used in probiotics produce histamines. When I discovered this, I looked up which ones do, and all three I discovered are used in this one. If you're sensitive to histamines or have leaky gut (which makes you sensitive to histamines), then this is not for you. According to an article on bullet proof, an overload of histamines "leads to increased inflammation and many other symptoms including: skin irritation, hives, throat tightening, increased heart rate, nasal congestion, migraines, fatigue, heartburn, reflux, and weight gain." I'm sure this can work for some people, but probably only despite the histamine-producing bacteria.

The two main species you want to look for are: Lactobacillus and Bifidobacterium. Within these two species, there are a lot of different strains. The strains we chose for our probiotic—Lactobacillus acidophilus, Lactobacillus plantarum, and Bifidobacterium longum—have been shown to help modulate the immune system, help with autoimmunity conditions (which affect most of my patients), and counter infections in the gut.
The National Yogurt Association, who created this seal of approval, requires all yogurt manufacturers to include it on products that meet the standard of having a sufficient number of probiotics. The probiotics in store-bought yogurt need to meet this standard in order to be shelf-stable and reach your body alive. But even then, this standard isn’t all that useful in practice. The number just refers to the total number of live cultures and not the levels for each of those microbes. It’s possible, Taub-Dix says, that a product won’t have high enough levels of a certain probiotic to have any effect.
Several large-scale studies and two meta-analyses have confirmed that probiotics should be a major consideration in determining natural remedies for diabetes. In a massive study involving almost 200,000 subjects and a total of 15,156 cases of type 2 diabetes, researchers confirmed that a higher intake of probiotic-rich yogurt reduced the risk of developing diabetes.

While past studies have investigated similar questions, they have all used patients' excrement as a proxy for microbe activity in the GI tract. Instead, Elinav, his colleague Eran Segal, (a computational biologist at the Weizmann Institute), and their teams spearheaded by Niv Zmora, Jotham Suez, Gili Zilberman Schapira, and Uria Mor of the Elinav lab collaborated with Zamir Halpern, Chief of Gastroenterology at the Tel Aviv Medical Center to measure gut colonization directly.

Diversity of strains - research has demonstrated that bacteria prefer to colonize in different parts of your digestive tract, where there are various ecological niches. The more probiotic strains you ingest, the more coverage you’ll provide for each of these niches. Each strain of bacteria also has its own different purpose, so choosing a formula with many different strains gives you that many more benefits.
She totally did, but you may have noticed that you don't see those yogurt commercials anymore. That’s because in 2010, the Federal Trade Commission in conjunction with 39 states' attorney generals banned those ads, finding that the Dannon Company had no scientific evidence to back up their claims,. Dannon had to pay $21 million to resolve the associated investigations.
Scientists are investigating probiotics, and their combined effects, by trying to classify the probiotic benefits of ingesting specific probiotic strains and understanding their role in the digestive tract. At present, the methodological and ethical limitations of human studies still make it difficult to fully understand the mechanisms of action of probiotics, but some explanations are available. Nevertheless, benefits linked to the consumption of probiotic strains have already been suggested (e.g. helping to support the immune system, help support digestive health), and others are still being investigated.
More common than diarrhea is the opposite problem — constipation. In a search for studies on the benefits of probiotics in treating constipation, researchers found that probiotics slowed "gut transit time" by 12.4 hours, increases the number of weekly bowel movements by 1.3, and helped to soften stools, making them easier to pass. But the jury is still out on specific recommendations when it comes to the benefits of probiotics for constipation.

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.
Many studies have shown that probiotics reduce diarrhea associated with taking antibiotics in both adults and children. In fact, it is common for physicians and pharmacists to recommend eating a probiotic-fortified yogurt every day during a course of antibiotics to prevent diarrhea. More research is needed to determine which probiotics are associated with the greatest effect for specific antibiotics.
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.
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.
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.

Jigsaw Essential Blend Probiotics uses five of the most researched (and effective) live strains to promote a healthy digestive system, restore flora after antibiotics use, and help with optimal vitamin absorption. Jigsaw products are also third-party certified, so you can rest assured that each batch is safe and pure. The bottom line? If you’re looking for a vegan-friendly formula — the capsules are made from HPMC (Hypromellose - Hydroxypropyl Methylcellulose), gelling agent (Gellan gum), and water — with a high CFU count, this product is for you. There are 90 capsules per bottle.
Our gut is home to over 500 bacterial species. These “visitors” form a bioreactor, which facilitates digestion, provides nutrients, and helps form the immune system. Some important nutrients made by this bioreactor include several B vitamins, vitamin K, folate, and some short-chain fatty acids. Up to 10% of an individual’s daily energy needs can be derived from the byproducts of the good bacteria in your gut.
If you've ever been to an Indian restaurant, then you've probably seen a lassi—a smoothie made of milk, yogurt, fruit, honey, and cardamom. The drink goes well with spicy Indian food because it helps extinguish the fiery feeling in your mouth. If you want to try it at home, you can pick up bottles from brands like Dahlicious, which contain 15 billion live probiotics per serving and are available in flavors like mango and turmeric. Or, try this mango lassi recipe.
​​​​​​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.*
Lebwohl says IBS isn’t just about intestinal distress. For many IBS sufferers, it’s about the way our brain receives messages about pain. He describes the human colon as “almost reptilian” in the way that it contracts and relaxes throughout the day, but says these contractions are usually happening way below our threshold of consciousness, so we don’t even notice. In people with IBS, the neurotransmitters in our gut (yes, we have them in there too) may be sending severe distress signals to the brain about benign contractions happening in digestive tract.
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!
It has been suggested that probiotics be used to treat problems in the stomach and intestines. But only certain types of bacteria or yeast (called strains) have been shown to work in the digestive tract. It still needs to be proved which probiotics (alone or in combination) work to treat diseases. At this point, even the strains of probiotics that have been proved to work for a specific disease are not widely available.
Unless you know that your body is lacking in a particular type of probiotic, you should just look for broad-spectrum probiotics that contain a mix of different strains of bacteria, Warren says: "We have billions of bacteria in our gut, so by taking a supplement with a range of different strains, you will ensure you are not overdoing or missing one type." Keatley also stresses the importance of finding a supplement with a diversity of bacteria strains to keep overgrowth of any one strain in check. "Providing too much of an advantage to one strain of probiotic may push out another strain we didn't know was important until it's too late," she points out.
Research indicates that the gut and brain are in constant communication, and the health of your gut can have a big, supportive impact on your mental health and well-being.17 One reason is the role the gut microbiome plays in maintaining your hormones––in addition to oxytocin, your beneficial bacteria also support your levels of serotonin (the "happy hormone), and cortisol (which is associated with high stress levels).18 They also help encourage GABA, an important neurotransmitter that determines how your body responds to stress. When you support your microbiome with probiotics, it can help to keep everything balanced, but if it becomes unbalanced and unwanted bacteria take over, you can end up with a low mood and anxious thoughts.19
Many wondered whether probiotics could be therapeutic in other gastrointestinal disorders. Unfortunately, that doesn’t appear to be the case. Probiotics didn’t show a significant benefit for chronic diarrhea. Three reviews looked at how probiotics might improve Crohn’s disease, and none could find sufficient evidence to recommend their use. Four more reviews looked at ulcerative colitis, and similarly declared that we don’t have the data to show that they work. The same was true for the treatment of liver disease.
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.
You may have heard some questions over whether SBOs are safe: The NIH has a presumed case report, which hasn’t been 100 percent verified, of someone with Lymphoma getting septicemia from taking a SBO (the organism B. subtilis). Some say that if you have leaky gut, you should heal it before supplementing with SBOs. If you are immunocompromised or have cancer, you can consult with a physician first to be safe.
Probiotics help tip the balance back in favor of the good bacteria. In doing so, they may provide some relief if you have irritable bowel syndrome (IBS), ulcerative colitis, acute infectious diarrhea, and diarrhea associated with antibiotic use or Clostridium difficile (C.diff) infection. They also can boost your immunity, fight inflammation and potentially have beneficial effects on cholesterol.
Though capsules are ideal for quick, convenient consumption, powdered products are a great choice for anyone who wants to mix their probiotics with shakes or smoothies. The Hyperbiotics Organic Prebiotic Powder is a totally taste-free prebiotic powder that has inulin, FOS, resistant starch, and dietary fiber to help keep your gut health in line. Unlike probiotics, prebiotics works to nourish and grow the bacteria that is already in your body. This supplement also has acacia fiber, which is said to help suppress appetite and reduce gas and bloating. You can take between one and three scoops of powder a day, depending on how much microbial support you’re looking for. Each container comes with 375 grams or roughly 54 servings, and it doesn’t need to be refrigerated.
Probiotics also seem to ameliorate irritable bowel syndrome, a chronic disease characterized by abdominal pain, bloating, and frequent diarrhea or constipation (or a mix of the two). A 2014 review of more than 30 studies, published in the American Journal of Gastroenterology by an international team of researchers, determined that in some cases, probiotics help to relieve the symptoms of irritable bowel syndrome for reasons that are not entirely clear, although it may be that they impede the growth of harmful microbes. The researchers concluded, however, that they did not have enough data to recommend any particular strains of bacteria. Microbiologists often caution that a promising study on a single strain of a particular species of bacteria should not be taken as proof that all probiotics work equally well. “Bacterial strains are so genetically different from one another, and everybody has a different gut microbiota,” Allen-Vercoe says. “There will probably never be a one-size-fits-all probiotic.”
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.

Yes, they may help. Lebwohl says there are reputable studies that show a link between the use of probiotics and the reduction in IBS symptoms, citing this meta-analysis. It's estimated that 11 percent of the world population complains of symptoms like abdominal cramps, diarrhea, constipation, excessive gas and/or mucus in their stools. While for some the condition can be attributed to certain dietary triggers, others appear to be stress-related, which brings us to the heart of where many claims about the effectiveness of probiotics lie—in the gut-brain axis.


Animals, including humans, have microbes inside them that benefit them in multiple ways. These microbes are in a loose sense like probiotics, but the definition of probiotics was established to designate those microbes that have been isolated, studied, tested in a laboratory dish and/or clinically in animals and/ or humans, and proven to have beneficial properties. In many cases their genetic fingerprints were sequenced for identification purposes and also to check for potentially harmful genetic components. The official term “probiotics” established specific criteria for scientific studies and probiotic supplements, foods, and drinks.
However, these quality of life improvements are varied, and some improvements are quite mild. Sample group, types of allergies, symptoms, and results are across a broad spectrum. For example, numerous studies have shown that allergic rhinitis responses to the household dust mite decrease significantly in adults and children when probiotics were used. However, people allergic to birch pollen saw neither a decrease in general allergic responses to birch pollen or to apple food.
Stability and organism types — Some probiotic strains need to be kept cold in order to preserve their potency. This applies to their production, transport, storage and sales. Others are shelf-stable and don’t require refrigeration. Unfortunately, most refrigerated probiotics never make it past the stomach because they aren’t stable. Instead, look for a shelf-stable product that contains soil-based organisms.
Cleaning up your diet to remove things that bother you and to add nutrients you and your microbiota need, physical activity to reduce stress and increase feel-good neurotransmitters, mindfulness to discover how your thoughts affect your feelings, and daily consumption of probiotic pills and foods are easy ways to improve your mental health outlook.

CFU: This is the number of "colony forming units" present in each dose, which are measured in the billions. And while more isn't always better, "you want at least 20 to 50 billion CFU," says Dr. Nazareth. Just for reference, a very high dose is 400 CFU, which most experts agree is not necessary unless your health care practitioner specifically recommends this for you. It's also important to check for the guaranteed CFU upon expiration, which should be listed clearly. "Some products only guarantee the CFU number at the time of manufacturing, therefore will be less potent by the time the product reaches your home," she says. 

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.

Uncontrolled changes in blood sugar levels or a decreased ability to regulate insulin can have serious effects on your overall health, and since far more men than women are at risk for these changes, these issues are well worth paying attention to.5 Research indicates that regularly taking probiotic supplements containing Lactobacillus and Bifidobacterium can help your body maintain blood sugar levels already within a normal range, whether you're simply at risk for insulin-related challenges or you're already experiencing them.


You may have heard some questions over whether SBOs are safe: The NIH has a presumed case report, which hasn’t been 100 percent verified, of someone with Lymphoma getting septicemia from taking a SBO (the organism B. subtilis). Some say that if you have leaky gut, you should heal it before supplementing with SBOs. If you are immunocompromised or have cancer, you can consult with a physician first to be safe.

Ultimate Flora tested significantly higher than the majority of general probiotic blends. Critical Care is composed of very well-documented probiotic strains and is an effective addition to any lifestyle, capable of conferring a wide variety of health benefits. The probiotic strains are not only diverse, they were also resilient to outside influences and, in many cases, were successful in establishing colonies within the digestive tracts of study participants.
While past studies have investigated similar questions, they have all used patients' excrement as a proxy for microbe activity in the GI tract. Instead, Elinav, his colleague Eran Segal, (a computational biologist at the Weizmann Institute), and their teams spearheaded by Niv Zmora, Jotham Suez, Gili Zilberman Schapira, and Uria Mor of the Elinav lab collaborated with Zamir Halpern, Chief of Gastroenterology at the Tel Aviv Medical Center to measure gut colonization directly.
Today, most of the Japanese population begins the day with a warm bowl of miso soup, believed to stimulate the digestive system and energize the body. Made from fermented soybeans, rice or barley, adding a tablespoon of miso to some hot water makes an excellent, quick, probiotic-rich soup. The fermentation process can take anywhere from a few days to a couple of years to complete, and the end result is a red, white or dark brown paste with a buttery texture.

Probiotics seem to be all the rage these days. With many purported benefits and a relatively low risk of side effects, manufacturers are taking advantage of booming business opportunities. Rather than leave your health in the hands of big business, it is important that you be as educated as possible about the best types of probiotics so you can choose what is right for you and your family.
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.
