Find out more information on deficiency, supplementation, sun exposure, and how vitamin D relates to your health.

Are there any chronic health conditions, diseases, or disorders that are negatively affected by vitamin D supplementation or sun exposure?

    Those with vitiligo should avoid sun exposure. If you have a parathyroid or granulomatous disorder or kidney disease, you should avoid vitamin D supplementation until you get the go-ahead from your doctor.
