A member asked:

My 30 year old boyfriend's blood test result showed 16 in d-vitamine level. his doctor prescribed 85 g d-vitamine to be taken 2-3 months. since treatment began a few days ago, he naps more than once per day. could the d-vitamine be causing this?

A doctor has provided 1 answer

Unlikely: Vitamin D supplementation is an unlikely cause of these symptoms. If the symptoms persist more than 7-10 days, talk to your doctor.
