It's not the first time I take Keybiotics, but I am always impressed with the results each time. I never had a problem with their customer service. I wish they were a bit less expensive, but when I compared with the other probiotics on the market, Keybiotics still offers more at a better price (especially if you buy in bundles). Oh, you will sure find some brands out there that are cheaper, but if you do the math and consider the number of different strains and the total amount in billions, the other brands on the internet (and in-store) are usually offering less for the same price or higher.
Also, I need to mention that some people really have unrealistic expectations when it comes to probiotics. For example, I gave one of my bottles to an elderly person I know who is legally blind and has about all the symptoms of Candida albicans you could think of, but she did not persevere and took them for only two weeks.
Then she said it was doing "nothing" because she still couldn't see!
Bottom Line: Yes, I would recommend this to a friend
