Vitamin A+D3 mse pairs two fat-soluble vitamins that were chosen specifically because of how they behave together, not just individually. Each daily dose of 2 capsules delivers 2,666 IU (1,010 mcg) of vitamin A as retinyl acetate — the naturally occurring storage form the body itself uses — alongside 2,000 IU (50 mcg) of vitamin D3 as cholecalciferol.

Research into the two nutrients shows a synergistic relationship: vitamin A helps activate vitamin D3, while pairing the two roughly triples D3's absorption compared with taking it alone; in isolation, each vitamin has even been shown to draw down levels of the other over time. Their roles in bone and calcium metabolism are similarly complementary — vitamin D3 raises blood calcium levels and supports phosphorus absorption in the small intestine, while vitamin A helps direct that calcium toward bones and teeth rather than soft tissue.

Beyond bone health, vitamin A supports healthy mucous membranes, normal skin, iron metabolism, and eye health — it's a structural component of the retina's photoreceptors, contributing to color and low-light vision. Vitamin D3 additionally supports normal immune system function.
