Supplements from The Diary of a CEO

16 supplements and daily-health items from The Diary of a CEO — the densest health slice in this catalog. The format explains it: Steven books clinicians and researchers and then asks what they personally take, and specialists asked that question tend to answer it concretely.

A significant share of this list comes from a small number of episodes. One conversation with a practising doctor can produce an entire protocol — several forms of one mineral, each for a different purpose — rather than a single passing mention.

Read the attribution line on each entry. Where a brand was named, it says so. Where only a compound was discussed, the entry quotes what was said and the Amazon listing beneath it is our pick, not the guest's.
