Probiotic supplements are taken in pill form or as liquids, powders, tablets and capsules, according to WebMD. Another common way to take probiotic supplements is to eat foods, such as yogurt, that have a high probiotic content.
Because so many varieties of bacterial supplements are available, making good choices at the supermarket can be difficult and expensive. For this reason, WebMD recommends speaking with a doctor before supplementing your diet with probiotics. Probiotic supplements are used to treat many gastrointestinal issues, such as lactose intolerance and diarrhea, according to WebMD, so the more information you can obtain about your potential purchase, the more likely you are to choose the right product and save money.
It's possible to supplement your diet with naturally occurring probiotics as well. Probiotic strains of bacteria are found in soft cheeses as well as many other dairy products. WebMD suggests taking your doctor's recommendation about which method and which type of probiotic is right for you.
ConsumerLab is a website devoted to reviews of common dietary supplements, including probiotics. The site is a great place to begin your search for a reliable brand of probiotic supplement, once you have discovered which strain of bacteria you would like to take and how you would like to take it.
