Unfortunately, none of these data are usable because (in the US, at least) there is no oversight on labeling accuracy for nutritional supplements.
That means I can dump woodchips into capsules and sell them as Multivitamins with 12 vitamins & minerals, and nobody would be the wiser.
There is more rigorous testing being done in underground steroid + peptide communities than in legal nutritional supplements.
Crazy world where you can trust vialed peptides from China more than something you bought on Amazon...
Sort've related, but here in Australia pet food manufactures are not required to list the nutritional content of their foods, whereas in the US as I understand it they do.
Supplements should at least be regulated like food. List of ingredients and tests that contains ingredients and doesn't contain anything harmful.
That's true. US is a wild wild west in that regard. However, I am working next to clearly label which supplements have COA vs which are unverified.
