- mdorazio 6y agoHalf-life of 15 hours or ~15 days depending on the variant [1]. [1] https://www.uspharmacist.com/article/vitamin-d-supplementation-an-update https://www.uspharmacist.com/article/vitamin-d-supplementati...
- smaryjerry 6y agoRight. To clarify half life means the rate it divides in half so after 15 days about half of what you took 15 days ago is left, after another 15 days half of that is left or 25 percent of the original amount, and so on. So it stays in the body for months if you get enough vitamin D.
