At the end of last year, there were several attention grabbing headlines spouting the redundancy of multivitamin supplementation. "Multivitamins are a waste of money." "Multivitamins Don't Improve Health."
There was such a huge bandwagon of articles written about the studies that were shown to "not improve cognition or life expectancy."
This is an excellent video on why these studies were a joke. I found Dr. Rhonda Patrick on a Joe Rogan Podcast and was impressed by her knowledge base.
