Prebiotics are fuel for the good bacteria (probiotics) in your gut; without prebiotics, probiotics can’t do their job. There are tons of prebiotics in whole fruits and vegetables, including onions, garlic, bananas, asparagus, and artichokes. If you’re worried you’re not getting five to 20 grams per day (more on prebiotic-rich foods here), consider taking a prebiotic supplement, usually a powder or drink mix.
While more research is necessary to fully understand the benefits of different probiotic strains, we do know that not all probiotics are created equal. The Lactobacilli, for instance, live in our digestive, urinary, and genital systems and can be found in some fermented foods like yogurt. Bifidobacteria normally live in the intestines as lactic acid bacteria, and are also found in fermented foods. According to nutrition expert Alex Caspero, RD, “For certain conditions, you want to ensure you’re taking the strand that is most likely to benefit you.” Here’s a simple breakdown to help you determine the best probiotic for you.
It’s great to get some healthy sour foods. I often add one tablespoon of apple cider vinegar to a drink, twice a day. Before breakfast and lunch or breakfast and dinner, add one tablespoon of apple cider vinegar in your meal, and then start consuming more fermented vegetables like sauerkraut and kimchi, or drinking kvass. Is apple cider vinegar a probiotic itself? No, but apple cider vinegar probiotic content makes it an excellent source of probiotics benefits.
Bifidobacteria were first isolated from a breast-fed infant by Henry Tissier, who also worked at the Pasteur Institute. The isolated bacterium named Bacillus bifidus communis was later renamed to the genus Bifidobacterium. Tissier found that bifidobacteria are dominant in the gut microbiota of breast-fed babies and he observed clinical benefits from treating diarrhea in infants with bifidobacteria.
If you have annoying tummy troubles... Allow your predominant symptoms to guide you. Bloated and constipated? Look for lactobacillus acidophilus or lactobacillus casei, which help restore gut flora. Can't stop going number two? Types with saccharomyces boulardii can ease antibiotic-associated diarrhea and even prevent extreme cases caused by infections.
Probiotics are found in everything from chocolate and pickles to hand lotion and baby formula, and millions of people buy probiotic supplements to boost digestive health. But new research suggests they might not be as effective as we think. Through a series of experiments looking inside the human gut, researchers show that many people's digestive tracts prevent standard probiotics from successfully colonizing them. Furthermore, taking probiotics to counterbalance antibiotics could delay the return of normal gut bacteria and gut gene expression to their naïve state. The research publishes as two back-to-back papers on September 6 in the journal Cell.
Digestive tract conditions. Probiotic supplements may be useful in treating and preventing inflammatory conditions, such as pouchitis (which affects people who have their colons removed), inflammatory bowel diseases (such as ulcerative colitis and Crohn's disease), and chronic stomach inflammation and ulcers caused by Helicobacter pylori bacterium. They may also be helpful in treating constipation, irritable bowel syndrome, acid reflux, spastic colon; shortening the duration of infectious diarrhea; and reducing the recurrence of bladder and colorectal cancer. Some studies suggest that yogurt is helpful in preventing diarrhea - a common side effect of treatment with antibiotics. It has also been shown to prevent or treat urinary tract infections and vaginal yeast infections in women.
Even if some of the bacteria in a probiotic managed to survive and propagate in the intestine, there would likely be far too few of them to dramatically alter the overall composition of one's internal ecosystem. Whereas the human gut contains tens of trillions of bacteria, there are only between 100 million and a few hundred billion bacteria in a typical serving of yogurt or a microbe-filled pill. Last year a team of scientists at the University of Copenhagen published a review of seven randomized, placebo-controlled trials (the most scientifically rigorous types of studies researchers know how to conduct) investigating whether probiotic supplements—including biscuits, milk-based drinks and capsules—change the diversity of bacteria in fecal samples. Only one study—of 34 healthy volunteers—found a statistically significant change, and there was no indication that it provided a clinical benefit. “A probiotic is still just a drop in a bucket,” says Shira Doron, an infectious disease expert at Tufts Medical Center. “The gut always has orders of magnitude more microbes.”
All probiotic strains are manufactured through fermentation, and are then freeze-dried before blending with fructooligosaccharides (FOS). The result is a shelf-stable (two years at room temperature), nitrogen-filled probiotic of human origin: a probiotic that easily adapts to your body, and is both acid- and bile-resistant to survive the acidic environment of the human stomach. In other words, a probiotic that fulfills its promises.

Eating foods rich in good bacteria and using probiotic supplements may help provide protection from inflammatory bowel diseases, including ulcerative colitis and Crohn’s disease. The evidence is stronger, however, for an improvement in ulcerative colitis, while Crohn’s disease may not benefit as greatly. In addition, there is ongoing research studying the role of probiotics in gluten issues, including celiac disease.
Like adults, children also require the proper balance of flora in the stomach to remain in good health. A major health care study conducted by the American Academy of Pediatrics concluded that probiotic supplements could be beneficial for children under certain circumstances. More research is needed. However, the study indicates that children who take probiotics at the first signs of viral diarrhea exhibit symptoms for shorter periods of time than those who do not. The study also found positive evidence that probiotics reduce the chances of diarrhea caused by antibiotic use in kids. More research is required to confirm these results. However, many pediatricians already recommend probiotics to parents based on the data.
Unfortunately, many commercial brands don’t measure up. They are unstable in stomach acid. Quality control measures aren’t intact, including ensuring supplements have been handled correctly and maintain their freshness. Moisture slipping into probiotic supplements can reduce their efficacy. Companies that use bioshield capsules produce higher quality probiotic supplements that are able to endure the stomach acid, releasing their contents within the small intestine, where a more alkaline environment ensures the survival of the bacteria.
For the generally healthy person, you can make a very good case to trust your own body to select and grow the best bacteria that are already in everyone. The foods you eat greatly influence your bacterial mix. Although probiotics offer many positive health benefits, there is no guarantee that they can make the trip from your mouth to your lower gut intact. Although adding more prebiotic fiber to your diet cannot guarantee safe passage of probiotics, it can influence the healthy bacteria that already live in your system. If probiotics help you, eating prebiotic foods or supplements will cause those healthy bacteria to flourish.
