A 2017 survey of cancer patients showed that more than 80 percent were taking some sort of dietary supplement, vitamin, mineral, or herb to treat digestive issues they were experiencing due to chemotherapy. Researchers noted that while supplements can be beneficial in some cases, they can also change the metabolism of anti-cancer drugs, or lead to life-threatening conditions like sepsis because of the patient’s compromised immune system.


Make sure dosages are listed in CFU, colony forming units. (Most brands list CFU in billions now: so 30 billion CFU, 100 billion CFU, and so on.) For one, this means that the bacteria strains are living, which is essential. When you’re looking at the cost of products, be sure to look at the cost per unit. I spoke to a woman the other day who had bought probiotics that had 2 billion CFU per capsule. In comparison, to get the 30 billion CFU I recommend, she’d have to take essentially half of her bottle to get the same dosage as one of our capsules.
When the digestive tract is healthy, it filters out and eliminates things that can damage it, such as harmful bacteria, toxins, chemicals, and other waste products. The healthy balance of bacteria assists with the regulation of gastrointestinal motility and maintenance of gut barrier function. Research has shown some benefits for the use of probiotics for infectious diarrhea, antibiotic-associated diarrhea, gut transit, IBS, abdominal pain and bloating, ulcerative colitis, Helicobacter pylori infection, nonalcoholic fatty liver disease (NAFLD), and necrotizing enterocolitis.
“​You have all sorts of microbiomes in your body, in the lungs, the oral cavity, the vagina and of course the gut. Everybody was looking at the microbiome as just being about just good bacteria,​”​Afif Ghannoum said.  The elder Ghannoum, who is associated with Case Western Reserve University in Cleveland, OH, showed the importance of the fungal components of those microbiomes, he said.
If you get sick often, probiotics might be the immune booster you've been looking for. The Cleveland Clinic says they've been shown to strengthen immunity by enriching and replenishing the good bacteria in the body. And when you eat foods with probiotics regularly, it's easier for your body to produce vitamins and enzymes that help keep your intestines happy.
Hi Joan, it’s possible, but not ideal because most pill form probiotic supplements are designed to be protected from stomach acid until the capsule reaches the intestines. It’s impossible to say how many probiotic microorganisms would survive by taking them this way, but certainly less than if you swallow the pills. I would recommend trying a probiotic gummy product or some other probiotic that comes in something other than pill form rather than opening up the capsules.
Clinically shown to work in 7 days§, AZO Complete Feminine BalanceTM works differently because it contains the power of INTELLIFLORA,TM the only clinically proven blend with the 4 vaginal lactobacilli species most commonly found in healthy women.* Specially designed to restore the vagina’s microflora, it’s a safe and beneficial probiotic for women’s health—including pregnant women.*§ Add it to your daily regimen for help with protection and ongoing vaginal health support.*
But before you start reaching for the calcium supplements, there may be a more effective way to support your bone health. Like many other parts of the body, the health of your bones is closely tied to the health of your gut, especially your intestines. Temporary intestinal inflammation can trigger an immune response in which your body releases interleukins, proteins that have an immune function but also absorb bone tissue. If the temporary inflammation remains unaddressed, these molecules can take a toll on your bones, eventually weakening them.14
If this happens, it's time to consider switching to a new probiotic. Other reasons a probiotic may not be the right fit: SIBO or Candida. If you have either of these conditions, the strain of the probiotic could potentially make your symptoms worse. Remember, if you think a probiotic is not helping, seek the advice of a functional medicine provider to help you navigate the choices out there.

With the growing popularity of probiotics, there is a huge variety of supplements from which one can choose. The most important thing is to determine what type of probiotic microorganism you need for your condition. Do not just take the supplement that provides the most kinds of organisms. You need to do your research and be sure that there are scientific studies to support what you take. New research is emerging, so if you don't find what you need right now, keep looking. A doctor can help one decide if trying probiotics might be helpful for you and can advise you regarding the amount and type of probiotics that may be appropriate in your case.
We found the most evidence linking strains to antibiotic recovery, immune health, and IBS/IBD relief. We made checklists of the most researched strains that treat those issues (10 strains known to boost general health, six for immune health, seven for antibiotic recovery, and seven for IBS/IBD relief) and dug into ingredient lists to find the supplements containing the highest number of effective strains for each use case.
The other way that probiotics help is the impact that they have on our immune system. Some believe that this role is the most important. Our immune system is our protection against germs. When it doesn't function properly, we can suffer from allergic reactions, autoimmune disorders (for example, ulcerative colitis, Crohn's disease, and rheumatoid arthritis), and infections (for example, infectious diarrhea, H. pylori, skin infections, and vaginal infections). By maintaining the correct balance from birth, the hope would be to prevent these ailments. Our immune system can benefit anytime that balanced is restored, so it's never too late. 

The label should also specify that the living microbes are viable through end of shelf life or best by date rather than at time of manufacture to ensure the bacteria are still live when you take them and able to reach your colon. Quality trumps everything- supplements that are a bargain are typically not of quality. A good probiotic (depending on strands) can cost anywhere from $25-$60.

Coming in at a close second, our runner-up as the best probiotic for women is the Culturelle Women’s Healthy Balance Probiotic. As the #1 recommended brand by pharmacists, it is easy to see why so many women are turning to Culturelle for their digestive health. Featuring the LGG culture and a laundry list of other healthy bacteria, this probiotic offers a wonderful balance between digestive and feminine health. The Culturelle Women’s Healthy Balance Probiotic is also taken in an easy, chewable tablet and can even be taken during pregnancy, making it one of the most versatile formulas we reviewed!


Yes. Probiotics are incredibly important and effective. We know there are more bacteria in us and on us than our own human cells. The body is almost like a puppet—it is bacteria that really runs the show: They turn on enzymes, turn off genes, and dictate much of our health. We need them to break down nutrients, like copper and magnesium, so we can better absorb them. Interestingly, studies show that conditions like anxiety, depression, and weight gain can be transferred via fecal transplants (with mice), suggesting the broad impact bacteria has on health.
Update: I think this product is being smeared by a competitor! Look at all the reviews in April. Suddenly, a butt ton of not just negative but 1 star reviews. It's uncanny. So, what would compel a competitor to do such a thing? Well, it was the only 50 CFU, enteric coated & 20 strain probiotic on Amazon & it cost about 15 bucks. That, while products far inferior to it were priced for - often times - 2 or 3x as much.
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.
While this feature contributes to the efficiency of the product, it is unclear whether this product is vegetarian like some of the other probiotics we reviewed. Therefore, if you have any dietary restrictions or needs, this may not be the best probiotic for you and may, in fact, cause additional stomach upset or irritation. It is however gluten-free.
