Came here to post Jperm, highly recommended. Got me from never picking up a cube before to a sub 2 minute solve with the beginner’s method. He has a website as well with graphic instructions that is very handy

I was reading some breakdown recently, forget if it was the CDC or whoever, but basically they found that the vast majority of Americans were totally good on vitamin D when tested despite survey results indicating people didn’t get enough from their diet generally. This was attributed to sun exposure

Then I looked it up and in many cases you get your full dose of vitamin D from the sun in literally a few minutes lol. Honestly I think the whole supplement industry in general is just a very successful scam

Edit: found it, section of note is vitamin d intakes and status.

evidence suggests that the majority of people have sufficient serum concentrations of vitamin D based on the thresholds set by the Food and Nutrition Board

If your doctor literally told you to take it then that’s great. The constant fear mongering among the general public about supplements is the scam
