99% of multivitamins are nothing more than pharmaceuticals (chemically reproduced, isolated substances that were found in food, typically showing the most biological activity in vitro).
Thus, as someone who IFs, uses (nearly all) whole-food supplements (not isolated nutrients in a whole food base, they are very different!), and takes three days off a week from all my supplements (fasting days), I don't see this as applying to me at all.
Yes, I do believe that the 99% of isolated multinutrient combinations (multis) that people are taking, especially those that are megadosing, are harming their health. The results of this analysis are evidence of this. This is not a surprise to me.
