Although most studies have shown few, if any, negative side effects, it is important to keep in mind that research on probiotics is still in a preliminary phase. There may be some risk for people who have certain health conditions. As with any supplement, it is essential that before you begin to take a probiotic supplement, that you speak with your physician first to help to ensure that you will not be putting your health at risk.
The Golive Berry Probiotic and Prebiotic Supplement Blend is perfect for tossing in your bag or keeping in your desk. Each packet includes 15 billion CFUs and 15 different probiotic strains. It also has a soluble fiber prebiotic to promote the growth of good bacteria in your body. Each packet contains 30 calories and comes in five flavors including pomegranate, melon cucumber, citrus blueberry, and a flavorless option. It can be mixed in any hot or cold drink, but we recommend tossing the flavored packet into a bottle of water. You’ll get 10 packets in each order.
While Lebwohl isn't comfortable endorsing a specific brand publicly, he did say "a widely used brand in which the compound is bifidobacteria or lactobaccilus seems like a reasonable way to go in a patient who is eager to give this a try, but would be best done under the supervision of a healthcare professional.” He does advise looking for a supplement with between 1 billion and 10 billion colony-forming units, or CFUs.
Many avenues of research have examined probiotics benefits for skin, especially in children. Meta-analyses have found that probiotic supplements are effective in the prevention of pediatric atopic dermatitis and infant eczema. The integrity of gut bacteria is also connected to the development of acne, although the way this happens is still unclear.

“I recommend this to my patients because Metagenics provides high-quality, professional-grade supplements that are scientifically formulated,” says Crystal Karges, MS, RDN, a maternal health dietitian in San Diego. “Supplementing with the specific probiotic strains in this product can help maintain healthy vaginal microflora and support urogenital health. Recent research has found that consuming probiotics during pregnancy may reduce the chances of premature birth and preeclampsia in late pregnancy.”
These are live microorganisms that will not provide the promised benefits if they don't remain alive. The manufacturer and consumer must pay close attention to the conditions of storage at which the particular microorganism will survive and the end of their shelf life. The potency will indicate the number of viable bacteria per dose, and the purity has to do with presence of contaminating or ineffective bacteria.
When seeking out the best probiotic for you, consider your overall health, dietary needs, antibiotic use, GI challenges, and similar concerns. Then, review our list of the ten best probiotic supplements, which offer everything from raw probiotics, which must be refrigerated, to shelf-stable, slow-release probiotics that concentrate fewer CFUs in tiny, once-daily capsules.
Probiotics are actually bacteria – the “good” kind. Our bodies have trillions of these microorganisms, some harmful but the majority of them beneficial. “Good” bacteria help break down food and keep the “bad” bacteria at bay. Probiotic bacteria are found in cultured dairy foods like yogurt, fermented vegetables like kimchi and sauerkraut, and foods fortified with probiotic bacterial cultures. They’re also available in capsules.
A growing probiotics market has led to the need for stricter requirements for scientific substantiation of putative benefits conferred by microorganisms claimed to be probiotic.[3] Although there are numerous claimed benefits marketed towards using consumer probiotic products, such as reducing gastrointestinal discomfort, improving immune health, relieving constipation, or avoiding the common cold, such claims are not supported by scientific evidence,[3][10][11] and are prohibited as deceptive advertising in the United States by the Federal Trade Commission.[12]

Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host. For details, see FAO/WHO (2001) and the 2014 update by ISAPP: Expert consensus document: The International Scientific Association for Probiotics and Prebiotics consensus statement on the scope and appropriate use of the term probiotic.

Previous studies have been contradictory, with some yielding more positive results about the benefits of probiotics, but most of them looked at probiotics in stool samples, not directly in the gut itself. In the new research, the scientists used more invasive methods to take samples of gut bacteria directly from different areas of the digestive system.
Self-dosing with bacteria isn't as outlandish as it might seem. An estimated 100 trillion microorganisms representing more than 500 different species inhabit every normal, healthy bowel. These microorganisms (or microflora) generally don't make us sick; most are helpful. Gut-dwelling bacteria keep pathogens (harmful microorganisms) in check, aid digestion and nutrient absorption, and contribute to immune function.
Some yogurts contain the aforementioned bacteria; however, because they are sensitive to oxygen, light, and dramatic temperature changes, make sure to look for yogurts with “live and active cultures.” Many commercial yogurts are heat-treated or pasteurized, resulting in the loss of these valuable cultures.

If you have an immune system problem or another serious health condition, you may have a greater chance of issues. Some reports have linked probiotics to serious infections and other side effects. The people most likely to have trouble are those with immune system problems, people who've had surgery, and others who are critically ill. Don't take probiotics if you have any of those issues.
Further, there’s still a lot we don’t know. A recent study published in Cell compared how the microbiome of the gut reconstituted itself after antibiotic treatment with and without probiotic administration. The researchers found that probiotics (which might have improved diarrhea symptoms) led to a significant delay in microbiome reconstitution, if it occurred at all. And — again — this study was with purified strains of bacteria, which is not what you’re getting in probiotic-containing food.
