Description

Auto Immune Disease and Vitamin D Vitamin D is a nutrient hormone although it's not a vitamin in the classic sense. Vitamin D exists as an inactive prohormone until it is metabolized within the body to a steroid hormone. Deficiencies of vitamin D have been found to contribute to various cancers and autoimmune diseases, particularly conditions of type 1 diabetes, multiple sclerosis, and psoriasis. Recent studies indicate that there's a critical need for testing blood levels of vitamin D.
