POTS: Low vitamin D may be associated with fatigue, joint pains, and even depression. I do recommend being seen by a specialist before starting supplementation so that a baseline and other underlying diseases may be assessed. Vitamin D is a vitamin required by muscles and bones which is an area that rheumatologists managed. I will be happy to do a consult if needed.
