Deep dives

Importance of Vitamin A in Conjunction with Vitamin D

Vitamin A plays a crucial role alongside Vitamin D in various bodily functions. The relationship between the two vitamins involves a process known as heterodimerization, where the Vitamin D receptor binds and co-locates with the retinoic acid receptor. While Vitamin D is often in the spotlight, Vitamin A is equally essential but sometimes overlooked. It is vital to consider sources of Vitamin A, such as retinol from animal-based products and pre-vitamin A from vegetables. Supplementing with both Vitamin A and Vitamin D, either through supplements or dietary sources, is recommended to support overall health and immune system function.
