I agree. My doc sent me for blood tests in 2019 to see why I felt foggy brained and forgetful. Of all the things they tested for, it was D that showed up as deficient. It was dangerously low at 18 ng/mL. Things are much clearer now at ~60 ng/mL.

What is really interesting in relation to this discussion is an OTC memory product Prevegen. They claim the active ingredient is some compound from a jellyfish yet the only other listed ingredient is vitamin D3.

From what I've seen that is just a bunch of marketing hoopala.
