A study of 26 commercial probiotics found that none fully supported their label claims, and another study indicated 43% contained less than half the listed probiotic amount.

“Um, these are the three that I use. These are three that I've developed. And I will say that it's not easy. We we went to an exposition for contract manufacturers and we had maybe just estimating at least 70 manufacturers and then we filtered them through our quality assurance screening and only five came out the other side. Yeah. So, um, you know, and again, I'm always careful because the quality assurance claims are something that I feel like a lot of cell phone companies hide behind as a marketing angle and a way to jack up the price. Um, but you when you look at the information I just shared in terms of 43% of probiotics don't meet their label claims, that might be another part of the reason why people say, well, you know, I went to Whole Foods, I tried a probiotic, I went to CVS or Costco, and I didn't really see much of a response. it might be because of some of these quality assurance corners being cut.”
