Step No. 1 is consume more sour foods — it’s the top way probiotics benefits can be accessed. Embrace what I call “the power of sour” with sour foods like apple cider vinegar and fermented vegetables. They contain some probiotics, but also they contain certain types of acids like gluconic acid and acetic acid, healthy acids that support the function of probiotics (even functioning like prebiotics in some cases).
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.
And when you get leaky gut, food and other particles slip through the gut lining into your bloodstream. Your immune system does not recognize these, so it attacks, leading to food sensitivities and more inflammation. You might not even be aware of these sensitivities that take months or years to develop and can manifest as hives, allergies, chronic sinus inflammation, and migraines. They often become triggers for autoimmune disease or, for patients like Dawn, depression. This is why maintaining good gut health becomes crucial, and why havoc occurs throughout your body when your gut goes bad.
As far as effectiveness, keep in mind that unlike medications, dietary supplements do NOT need to be approved by the FDA. This means that manufacturers can sell supplements simply with "claims" of safety and effectiveness. Currently, researchers are undecided if probiotic supplements are effective. Some say probiotics are effective; others believe they offer no benefit whatsoever. It also remains unclear which probiotics (or combination of probiotics) work to treat certain diseases. Despite these issues, some studies have shown positive results. Still, more research is needed to confirm that probiotics are safe and effective.
Probiotic All-Flora delivers 5 billion CFU (colony forming units) of friendly bacteria and 5 billion CFU of beneficial yeast that work in synergy to balance your total microbiome. Our formulation is optimized to support healthy immune defenses and promote digestive health including bowel regularity and the reduction of occasional gas, bloating, diarrhea, and constipation.* All in just one capsule daily. Great for travel and times of GI distress, too. Shelf-stable, no refrigeration required.
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.
The large intestine is home to hundreds of trillions of bacteria. Fortunately, most are neutral or even beneficial, performing many vital body functions. For example, they help keep “bad” bacteria at bay, play a role in immunity, help us digest food and absorb nutrients and may even have anticancer effects. But will consuming them as probiotics in foods or capsules make a notable difference to your health—especially if you are already healthy? Here’s a look at the evidence.

Abdominal pain can have many causes that range from mild to severe. Some of these causes include bloating, gas, colitis, endometriosis, food poisoning, GERD, IBS (irritable bowel syndrome), ovarian cysts, abdominal adhesions, diverticulitis, Crohn's disease, ulcerative colitis, gallbladder disease, liver disease, and cancers. Signs and symptoms of the more serious causes include dehydration, bloody or black tarry stools, severe abdominal pain, pain with no urination or painful urination. Treatment for abdominal pain depends upon the cause.

B. bifidum has also been shown to prevent intestinal pathogens or digestive disrupters from flourishing in the gut, essential in restoring the bacterial balance and optimizing digestion. Clinical research found it supports a significant reduction in IBS symptoms, an improvement in quality of life and even helps relieve occurrences of ulcerative colitis, a chronic inflammatory bowel disease. [1].
Prebiotics are non-digestible food components that promote the growth of healthful bacteria in your gut. In essence, they are "good" bacteria promoters. In addition to improving digestive health, prebiotics can also enhance calcium absorption. Prebiotics are components of nondigestible fibers and are found in many plant foods. Rich sources of prebiotics include garlic, onion, leeks, asparagus, dandelion greens, and sunchokes. Prebiotics and probiotics work synergistically to optimize gut health. Hench, meals or products that combine these together have a symbiotic effect.
The GI tract plays an important role as an interface between the host and the environment. It is colonized by about 10 trillion microbes of many different species, amounting to 1–2 kg in weight [O’Hara and Shanahan, 2006]. Only a minority (300–500) of these species can be cultured in vitro and studied [O’Hara and Shanahan, 2006]. Intestinal epithelial cells have the capacity to distinguish pathogenic from nonpathogenic bacteria on the basis of their invasiveness and the presence of flagella, although the exact mechanisms that allow them to do this have not been elucidated fully [Borchers et al. 2009].
“Clients with tummy troubles, especially diarrhea, gas, and bloating have good success with Florastor,” says Cheryl Harris, a dietitian in Fairfax, VA. “It contains Saccharomyces boulardii, a special strain of probiotic yeast. Most probiotics are killed by antibiotics, but because Florastor is a probiotic yeast that encourages healthy bacteria, it’s an ideal one to take along with antibiotics.” Don’t miss 11 diseases that can start with gut bacteria.
Microbes are tiny organisms (bacteria, viruses, parasites, or fungi) -- so tiny that millions can fit into the eye of a needle -- that are so powerful that an imbalance in the body is related to numerous diseases. These microorganisms can be found in almost every part of the human body, living on the skin, in the nose, and in the gut. There are trillions of these microorganisms in our bodies. They outnumber human cells by 10 to one, but due to their small size, they only make up 1%-3% of a body's total mass.
The best case for probiotic therapy has been in the treatment of diarrhea. Controlled trials have shown that Lactobacillus GG can shorten the course of infectious diarrhea in infants and children (but not adults). Although studies are limited and data are inconsistent, two large reviews, taken together, suggest that probiotics reduce antibiotic-associated diarrhea by 60%, when compared with a placebo.
“Aside from the beneficial probiotics, this has plant-based compounds like ginger to soothe upset stomachs and support healthy digestive function,” says Beth Warren, MS, RDN, a dietitian in New York City. It also has prebiotics, which encourage the growth of healthy bacteria that support the well being of pregnant and breastfeeding women, she explains. “The formula has L. rhamnosus HN001, which has been shown to support the child’s developing immune system during the last trimester and early breastfeeding period.”
Survival past stomach acids - probiotic powder in capsule form is ill prepared when it comes to protecting the delicate bacteria from being pulverized by the harsh environment of the stomach acids. Worse, most of the organisms tend to die off before they reach their intended destination due to moisture that gets trapped between the capsule shell and the powder.
Along with about 30 other neurotransmitters, your gut manufactures about 95 percent of serotonin, the feel-good neurotransmitter that SSRIs keep circulating. (Worth noting: SSRIs prolong the time serotonin stays stimulating the neurons. These drugs don’t actually make serotonin. They falsely elevate the serotonin that is already there, leading to greater depletions down the road.)
Previous studies have investigated the use of probiotics — those healthy gut bacteria — by testing their impact in guts already affected by disease, the researchers wrote in the study. For the new investigation, they wanted to see how a probiotic would impact SCFA production in a healthy gut. They chose to work with baby poop because infants' gut microbiomes are typically free from age-related diseases "such as diabetes and cancer," and because of the sheer abundance of infant feces at their disposal. ("Their poop is readily available," Yadav said.)
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.
Bacteria die out over time. Some supplements list the potency when they were manufactured (before they rode in a truck, sat on the shelf at the grocery store, or hung out in the kitchen cupboard for a few months). In this case, there could be dramatically fewer viable bacteria by the time you consume them than when they were first encapsulated, and good bacteria are no good to you dead.
Though most probiotics are formulated for both men and women, Garden of Life’s Raw Probiotics for Women is manufactured with women in mind. This probiotic has a whopping 85 billion live cultures and 32 different probiotic strains to target everything from gut and vaginal health to thyroid and nutrient absorption. It contains two popular probiotics, Lactobacillus acidophilus and Bifidobacterium, and is gluten-free, soy-free, and made without fillers or binder—which is great for anyone with dietary restrictions or allergies. Each container comes with 90 capsules; the recommended dose is three capsules per day.
Prebiotics do contribute to a happy, symptom-free gut in the sense that they serve as fuel for the good microbes that help keep the digestive process humming. So while on their own they don’t do much, you absolutely need prebiotics for gut microbiome support and healthy digestion. Natural foods are by far the best source — supplements aren’t necessary if you’re eating a healthy, balanced, and veggie-rich diet.
Lacto-bacillus plantarum: If you’ve ever heard of the beneficial effects of fermented foods (pickles, sauerkraut, kimchi, etc.), then you’ve heard of this powerful probiotic, which may help improve the symptoms of IBS, gluten intolerance, soy allergies, and Crohn’s disease. This is also one of the most antibiotic-resistant probiotics, which is especially important if you have taken antibiotics recently.
Another systematic review of the literature evaluating efficacy of probiotics in the treatment of IBS revealed that probiotics had a statistically significant effect in reducing IBS symptoms with a number needed to treat (NNT) of 4 (95% CI 3–12.5) [Moayyedi et al. 2010]. Almost all probiotic combinations contained both Bifidobacteria and Lactobacilli; the latter had no effect as assessed by continuous data meta-analysis. This raises the possibility that Bifidobacter may be the active treatment in probiotic combinations.

Probiotics can help protect against common gynecological conditions such as bacterial vaginosis, candidiasis, and urinary tract infections, says Jennifer McDaniel, MS, RDN, CSSD, a dietitian in St. Louis, MO. “Bacteria can pass through our digestive system into the vagina, so we have the opportunity to consume probiotics that can benefit our vaginal health. L. rhamnosus GR-1 and L. reuteri RC-14 are evidenced-based probiotic strains for women’s urogenital health. Not only do they disrupt the infection of a range of unhealthy bacteria and yeast in the vagina, they offer benefits to the vagina and reduce the risk of problems such as bladder infections.” Fem Dophilus, made by Jarrow Formulas, has the critical strains and the company adheres to the highest production standards, she says.

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.
