In the United States, most probiotics are sold as dietary supplements, which do not undergo the testing and approval process that drugs do. Manufacturers are responsible for making sure they're safe before they're marketed and that any claims made on the label are true. But there's no guarantee that the types of bacteria listed on a label are effective for the condition you're taking them for. Health benefits are strain-specific, and not all strains are necessarily useful, so you may want to consult a practitioner familiar with probiotics to discuss your options. As always, let your primary care provider know what you're doing.
Probiotics for allergies are fast becoming a preferred treatment method because they are understood to be much safer than traditional allergic rhinitis medication. A nasal spray for allergies is often a ‘go to’ treatment, for example, but allergy nose spray medications often contain corticosteroids, like Beclometasone dipropionate, which could affect bone metabolism, blood cells, and the pituitary gland.

There are many health benefits of probiotics, but there are also a few cautions to heed as well. First, if you are immune compromised (catheters, cancer treatments, HIV, trauma, and so on), please consult your physician to check if there are any contraindications for using probiotics. Second, if you never used probiotics or a particular type of probiotic before, and/or never ate much raw food or indulged in fermented probiotic-rich foods and drinks (such as sauerkraut, kimchi, kefir, or kombucha), please proceed slowly with probiotic supplements and use. Although probiotics are tiny organisms, they can have very potent effects on your body.
Because there's a huge variety of probiotic products available on the market, many people struggle to find the right one for them. "There are many different strains of bacteria in different combinations within different probiotic supplements," explains Brooke Scheller, a clinical and functional nutritionist. "For example, a probiotic may contain a single strain of bacteria or many. It may also contain other vitamins, minerals, or other ingredients that may tout health benefits," she says. There are many different dosages, delivery systems (powder, tablets, capsules), and formulations (refrigerated vs. shelf-stable), and some probiotics also contain prebiotics, which basically act as fertilizer for the probiotics.

Reviews looking at the treatment or prevention of vulvovaginal candidiasis in women, pneumonia in patients hooked up to respirators, and colds in otherwise healthy people show some positive results. But the authors note that the studies are almost all of low quality, small in size, and often funded by companies with significant conflicts of interest.
To factor strain-specific benefits into our efficacy score, we referenced the information in these guides. Products were rewarded for containing strains on these lists. Additionally, measured levels of each strain were compared to what is thought to be effective based on these guides, and scores were scaled accordingly. In cases where products did not list strain-specific amounts, or their listed strains were not included in these guides, total measured CFUs were compared to a general effectiveness threshold of 1 billion CFUs cited by research published in the American Journal of Clinical Nutrition11.
Our gut is home to over 500 bacterial species. These “visitors” form a bioreactor, which facilitates digestion, provides nutrients, and helps form the immune system. Some important nutrients made by this bioreactor include several B vitamins, vitamin K, folate, and some short-chain fatty acids. Up to 10% of an individual’s daily energy needs can be derived from the byproducts of the good bacteria in your gut.
Importantly, patients with gastrointestinal conditions are not the only ones taking probiotics. 3·9 million people in the USA alone regularly take probiotic supplements, with promised benefits ranging from improved digestion and immune function to improved mental health and prevention of heart disease. However, evidence for these benefits is lacking, and because probiotics are often sold as supplements, manufacturers in many countries are not required to provide evidence of their safety and efficacy to regulatory bodies. The ubiquity of probiotic products would suggest that, at worst, they are harmless. Nevertheless, some safety concerns have been raised, including the risk of contamination, possibility of fungaemia or bacteraemia (particularly in immune-compromised, elderly, or critically ill individuals), small intestinal bacterial overgrowth, and antibiotic resistance. Adding to concerns, clinical trials of probiotics have not consistently reported safety outcomes.

Among their numerous health benefits, research shows these friendly microorganisms help prevent bowel diseases, improve your immune system, reduce traveler’s diarrhea, help you maintain a healthy weight, heal various skin conditions, improve bloating and other uncomfortable GI symptoms, and even boost your mood, helping to reduce the effects of anxiety and depression.
"Contrary to the current dogma that probiotics are harmless and benefit everyone, these results reveal a new potential adverse side effect of probiotic use with antibiotics that might even bring long-term consequences," Elinav says. "In contrast, replenishing the gut with one's own microbes is a personalized mother-nature-designed treatment that led to a full reversal of the antibiotics' effects."
The recent buzz has helped bring probiotics into the main stream.  Due to being covered on major news sites and television personalities, probiotic supplements are now more accessible than ever.  The main benefits of probiotics begin within the gut and digestive system.  The gut plays such an important role, that the level of healthy bacteria in our bodies can actually alter our mood.  It’s true!  What we eat actually affects how we feel.  This is why the gut has been called our “second brain”.
Hi Julia. I am 71 (male) and have had digestive issues for most of my life and no specific diagnosis. I eat fairly well, am not overweight, get gassy from many different foods and beverages. I have been using Culturelle for 9 months and feel the benefit from taking it is small. Your review leads me to believe there may be better choices. They certainly are not cheap but I will gladly pay for them if they give me results. I am probably going to try BlueBiotics unless you have other suggestions. My main question is since I live in Minnesota I will receive shipments in the summer with temps of up to + 100F and winters down to – 15F. Will this cause a decrease in product viability for this or other brands you recommended? Thank you for your help.
Notions don’t equal evidence though, and Lebwohl cautioned against thinking of probiotics as a cure-all, and examining the ways in which they’ve been proven to work as well as the ways in which they really haven’t. So which medical conditions have probiotics actually shown promise in treating and which claims have the credibility of a used car salesman on acid?
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.
