Not really related to the OP, but is there any scientific proof behind the whole industry of supplements? We have lived thousands of years without, even currently most people live without, and AFAIK we don’t give supplements to other species. It’s hard for me to think it’s not all snake oil.

Some even seem outright dangerous. One my girlfriend takes recommends 2 tablets per day (of Vitamin D I think) which equates 1000% of the daily recommended amount…
