Vitamin D

What is Vitamin D?

Vitamin D is a fat-soluble vitamin typically synthesized via UV light exposure. Having normal levels is essential for a good immune system and healthy mineral balance. [1] [2] [3]

Why is Vitamin D included in the Inflammation and Metabolic axes?

Evidence has shown that low concentrations of Vitamin D are associated with increased levels of inflammatory markers [1], and an increased risk of Metabolic Syndrome [2]. Metabolic syndrome is a cluster of conditions that occur together, increasing your risk of heart disease, stroke, and type 2 diabetes.
