Historically, I tell people who don’t have a tan over at least 50% of their body to get their D tested. Are you usually low in D? Do you expose your skin to sun usually? Or, do you usually protect your skin with SPF, clothing or shade. Being in the sun with 15+SPF is basically the same as being inside when it comes to vitamin D.
I think most people are deficient in D without supplement, unless they work in the sun all day or are purposely always trying to achieve a tan.
However, there is a caution that for a small set of people D can be dangerous if they have certain types of medical problems.
I take a huge amount of D to stay in normal range. I know a lot of people like me, but I know some people who don’t need as much. If I’m not in normal range my muscles are terrible.
If you usually get sun and aren’t now I guess you could take a little extra D. D stores up in the body, if you have recent blood tests and the number is very high normal you can probably float a while. Actually, check your calcium level if you have a recent set of bloodwork. If it’s normal I would say take some extra D for good measure. You can always just take a small amount. If your calcium is abnormal you need medical advice about taking D.
