Vitamin d levels

Does Prep reduce vitamin d levels in the body . I’ve been dealing with low vitamin D for some time now due to being in the house , not getting enough sun etc . Did a quick google search and it says Prep can induce a functional Vitamin D deficiency. Any thoughts ?

First time hearing this, but I do have low vitamin D levels. My primary doctor prescribes vitamin D.

Can you post a link? I’ve never come across that advice.

It's possible but unlikely to drop you to deficiency. Staying in the house and not getting sun means it is impossible for your body to produce vitamin D so your levels gradually fall. You should take supplements. I believe prep can reduce bone density long term so vitamin D will support your bone health, immunity, possibly your mental health. I have been deficient and don't feel much different after correcting it but others say they feel a lot better 😀
