No specific brand but this is my advice for choosing a probiotic:
Look for ones that have a minimum of 10 million live bacteria (I get ones with at least 20 million) and specific bacteria strains in the ingredients (for example don’t get ones that just list Lactobacillus acidophilus, get ones that list something like Lactobacillus acidophilus LA85 - the bacteria strain with an identifying number/letter - this is a particular strain of bacteria). They’re going to be the best. Ensure you consume and store it correctly as per its instructions.
I would not recommend buying anything like probiotics, vitamins, skincare products, makeup, shower products etc on Amazon as fake products are now being sold even through legitimate brands pages and sources, I would not trust you are getting legit products.
