Vitamin D deficiency isn’t great, but the health influencer industry really blew this out of proportion. The number of people taking excessive doses because they think more is better is getting scary.

You don’t need a lot of Vitamin D to avoid deficiency. Taking even 5000 IU for an extended period of time can cause Vitamin D excess.

Vitamin D confuses a lot of people because it accumulates over a very long time period. You can take the same dose every day but not approach overdose range for a year or more. It builds up if you’re taking too much, and there is a lot of overlap between “too much” and some of the regimens pushed by health influencers.
