Maybe I’m misunderstanding your post, but are you saying you’ve never come across mislabeling in the supplements you personally take? How would you know if you’re not getting them independently tested? (Maybe you are? If so, I’d be curious about which supplements/brands you’ve tested that seem consistently legitimate).
Independent labs exist that perform testing. I typically use LabDoor. The supplements aren’t perfect by any means, so I suppose there is some “mislabeling”, and maybe the supplements that are tested aren’t representative of what’s shipped to consumers. So, it’s about as accurate as anything else that’s sold to consumers with a nutrition facts label, in my opinion.
An incentive issue I am referring to is LabDoor is funded by companies - their business model is affiliates + requiring a fee from companies to list their products. Also their selection is very limited and testing methods opaque. I want to populate the table with one click access to CoA's and product testing.
This is a super interesting question. If you don't know, and it's difficult to find out, isn't your market going to be limited by the rate of consumer education? that is a difficult goto market strategy, because you have multiple funnel fallouts happening - people who don't want to get educated, can't get educated, don't believe the education. Then they enter your "do they want to buy your product" funnel. Tough space, but it sounds like it's a problem - good luck!
