I've been feeling a bit off lately and a friend mentioned it might be a vitamin D deficiency. Is there a specific test I can take to check for this? And what should the ideal levels be if I'm looking at the results?

Yes, a simple blood test, specifically the 25-hydroxyvitamin D (25(OH)D) test, can diagnose vitamin D deficiency; the ideal level is generally considered to be between 30-50 ngmL, with levels below 20 ngmL indicating deficiency, 21-29 ngmL indicating insufficiency, and above 50 ngmL potentially indicating toxicity
