Your gut health controls so many functions and is so important. Be careful when deciding which ones to buy. The one I use has 50 billion organisms and 19 strains. I read that the higher number of each, the better for you. You can find them here: https://www.amazon.com/gp/product/B01ISXH62U/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1

Also, here is one of the articles I read that covers the bases: https://www.humnutrition.com/blog/the-guide-to-choosing-the-best-probiotic-for-you/

Hope this helps you! Take care!
