Science uncovers more about the microbiota and the critical role it plays in our health. A daily dose of a research-proven probiotics can help correct dysbiosis, support your gut health (in a preventive way, or for more chronic ailments) or give your system an added boost when you need it, like after a course of antibiotics or when you are travelling. When choosing to add a probiotic into your health plan, be sure to understand why you are taking it, what dosage you need, what the specific probiotic strains are good for, and if it has the research to back up what it’s claiming to do.
Renew Life Ultimate Flora offers 30 billion CFUs with 10 scientifically studied strains of Bifidobacterium and Lactobacillus, which according to current scientific research, are the two most prevalent good bacteria found in a healthy gut. In other words, you might choose these if you’re seeking a careful balance designed to re-establish proper immune health and digestive equilibrium.
If you want to supercharge your probiotic friends, you may want to feed them with prebiotics. That’s P-R-E-biotics. They nourish the good bacteria in your gut in order to keep them healthy against the bad bacteria. They should go hand-in-hand with probiotics. Prebiotics are found in many foods, including bananas, whole grains, honey, garlic and onions. Try to get two to four servings of these prebiotic-rich foods a day.
Studies have shown some benefits linked to Lactobacillus and treating and/or preventing yeast infections, bacterial vaginosis, urinary tract infection, irritable bowel syndrome, antibiotic-related diarrhea, traveler's diarrhea, diarrhea resulting from Clostridium difficile, treating lactose intolerance, skin disorders (fever blisters, eczema, acne, and canker sores), and prevention of respiratory infections.
That said, supplements with higher numbers of CFUs are sometimes used to treat conditions such as irritable bowel syndrome (IBS), allergies, and respiratory illness. While probiotics have generally been found to be safe for most people with normal immune systems, too much can cause gas and upset stomach. We narrowed our search to supplements with dosages between 1 billion and 100 billion CFUs.
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.)
Eating more foods that are naturally rich in probiotics, like yogurt, kimchi and kefir, can help restore balance in your gut and create more “good” bacteria to fight off inflammation from “bad” bacteria. But what about food products that have probiotics infused into them? Indeed, manufacturers are banking on a new crop of gut-friendly products. From chocolates and granola bars to juices and tonics, nut butters, bottled water and even air sprays, you can’t escape the probiotic movement.
Though most probiotics are formulated for both men and women, Garden of Life’s Raw Probiotics for Women is manufactured with women in mind.

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.
"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."
Better Health Review named Dr. Ohhira’s Probiotics 12 Plus on its list of the top probiotic supplements on the market.

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.*
"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.

As a world-renowned neurologist and nutritionist, Dr. David Perlmutter has become somewhat of a household name when it comes to the linkage between what we eat and how we feel. He is known as “The Empowering Neurologist” and has been featured on the Doctor Oz Show, CNN, and NPR as well as in prominent publications like The New York Times, Forbes, Time Magazine, and the Wall Street Journal. If that wasn’t enough to spark your interest, Dr. Perlmutter is also the award-winning author of the Grain Brain Whole Life Plan, Brain Maker, and Grain Brain, all of which have become international bestsellers.
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.
The U.S. Clinical Guide to Probiotic Products1, Canadian Guide to Probiotic Supplements2 and the WGO Global Guidelines for Probiotics and Prebiotics3 provide suggested effective amounts of specific strains for treating certain health conditions, such as constipation or IBS. All 37 products listed the species of bacteria they contained, but only 14 listed amounts of individual strains. We found that 9 of those 14 products provided beneficial bacteria at effective levels. The Center for Responsible Nutrition recommends4 the industry move toward specifying strains as a best-practice because whether a product works and for what purpose depends on its strains.
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.
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.
While one 2009 study did show some evidence for reducing cold and flu symptoms in children ages three to five and a 2015 analysis showed probiotics to be better than placebo in preventing acute upper respiratory infections, neither were enough to convince the National Institutes of Health of the efficacy of probiotics for colds and flu. The NIH confirms, “the evidence is weak and the results have limitations.”
