Is there a subreddit for finding links to information?

I am looking for information on severe Vitamin D deficiency and it's long term effects. For eaxample, I have been severe Vitamin D deficiency for years (since 2010 that I know of for sure). I am trying to find out what health issues I could be facing are, and treatments when all of the supplements make me sick.

I am not looking for doctors advice (I see one) or dietary advice. I just want links to articles and such.

Apparently my son and I are the 2nd and 3rd lowest levels he has ever seen. I am at 6 last time they checked and he is below 5, if that helps.
