Bacillus subtilis stands out from other strains of bacteria because it’s one of the few types that is able to grow and thrive in a variety of diverse environments, including in soil, on the roots of plants and in the gastrointestinal tracts of animals. (5) Animal models suggest that it may be in the running for the best probiotic for diarrhea, noting that it can improve both growth performance and digestive health. (6)
"I recommend supplementing with the species lactobacillus and bifidobacterium, and there are different strains within those species that are each beneficial. Garden of Life and Align probiotics contain bacteria that help the gut microbiome and maintain digestive balance, and 1MD's Complete Probiotics Platinum is one of the best probiotics with over 50 billion live cultures that help with gut and digestive health."

This probiotic doesn’t contain any bacteria that produce histamine, a substance linked to inflammation, according to Nour Zibdeh, MS, RDN, CLT, an integrative and functional dietitian in Washington, DC. “Histamine intolerance is more common in women because of estrogen. The higher your estrogen level, the more histamine your body will produce. Symptoms of histamine intolerance include headaches, itchy and red skin, anxiety, congestion, post-nasal drip, stomach pain, diarrhea, and period cramps. If these symptoms are worse at ovulation or right before your period, I suspect histamine intolerance and recommend a probiotic that will help break histamine down.” Dr. Zibdeh recommends this brand. “It’s a mix of strains that are either neutral or may help metabolize excess histamine,” she explains.
To avoid those and other problems, I strongly recommend buying a professional brand from a reputable health care professional or other vendor who stands by their products and undergoes third-party testing. Some of these professional brands have created advanced technology that preserves a probiotic supplement’s survival on the shelf and in your gut.
Chlorella, a type of green algae, is thought to be one of the most nutrient-dense foods available. It contains chlorella growth factor (CGF), a complex of proteins, vitamins, and sugars that works with fiber in the GI tract to promote the growth of healthy intestinal flora. It also contains chlorophyll, a potent antioxidant that binds to toxins and helps remove them from the body. “Chlorella is known for detoxification, but I’ve found that it does wonders for promoting normal GI function,” Dr. Rawls says.

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.
Probiotics are generally considered safe8 for most healthy people, but may cause gastrointestinal discomfort (abdominal tenderness, pain, gas, and/or diarrhea) if intake exceeds individual needs. People with certain health conditions like suppressed immunity or sensitivity to probiotics may experience more severe side effects9. Probiotics can also interact with some medications. Please consult your doctor before starting any new supplement.
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.
Every day, we’re exposed to toxins and inflammation-causing molecules from food and the environment that negatively impact digestion through pathways, such as leaky gut, known in the medical field as intestinal hyperpermeability. In leaky gut, the tight junctions that are supposed to keep disease-contributing compounds from leaving the digestive system are disrupted, allowing a lot of things through into the bloodstream that don’t belong there.
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.

As you age, your body needs different supplements and vitamins to stay healthy. Renew Life 50+ Ultimate Flora Probiotic is a smart choice for adults over 50 because it is specifically formulated with seniors in mind. It has 30 billion live cultures and 12 strains of probiotics, including Bifidobacteria, which is a probiotic that decreases in your body as you age. Seniors develop less of the “good” bacteria as they age, and Ultimate Flora has three times the average live cultures in each dose to help replenish and protect gut and immune health. This 60-day supply should be refrigerated to maintain the live cultures.
Pure Therapeutics Power Probiotic 100B offers 100 billion CFUs of 4 powerful probiotic strains, including science darling, the HN019 strain of Bifidobacterium lactis. Since environmental factors, including moisture, oxygen and heat, can degrade the stability of your probiotics, Pure Therapeutics 100B is delivered in nitrogen-purged aluminum blister pacts, which ensure viability until the probiotic hits your system. No refrigeration is required.

If these issues and many others are connected to gut health, then what elements are essential for digestive health? Consider this: According to the National Institute of Diabetes and Digestive and Kidney Diseases, upward of 60 million to 70 million Americans are affected by digestive diseases. In addition, digestive disease and disorders cost the United States over $100 billion per year.

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.
In the past, probiotics have been proposed as part of a weight loss diet. However, a 2015 meta-analysis looked at available randomized, controlled trials investigating this effect and determined that the studies did not seem to support this hypothesis, as body weight and BMI were not consistently reduced. The researchers did point out the need for better designed trials, because they were not convinced the results were based on well-designed science.
Probiotics, like all strategies for helping promote your health, might not work for everyone. People have different diets, the microbes colonizing their gut are specific to each of us and everyone’s physiology is unique. Research often shows that some people respond to a specific probiotic strain and others do not. So if you feel a probiotic is something you’d like to use, one strategy is to try a product for about a month. If you don’t see a benefit, then perhaps it’s not the right one for you.
Lactobacillus predominantly live in your small bowel (the portion of your gut that follows the stomach). Probiotics containing Lactobacillus sp. help to repopulate the small intestine with friendly organisms that aid in supporting digestion and immune function. The most beneficial are L. acidophilus, L. plantarum, and L. paracasei. One study found Lactobacillus acidophilus could reduce gut inflammation. L. rhamnosus helps increase GABA expression (an inhibitory neurotransmitter that helps you feel relaxed) in the brain, resulting in lower anxiety and depression-related behavior. Another found that a combination of Lactobacillus and Bifidobacteria (which we'll talk about next) improved symptoms of bloating in patients with functional bowel disorders, and yet another found that when people took the Lactobacillus rhamnosus GG strain, it significantly reduced the risk for antibiotic-associated diarrhea.
