The Essential Guide to Vitamin D3 and K2 Supplements

Vitamin D3 and K2 are essential nutrients that work together to support bone strength, calcium immersion, and cardiovascular health. While D3 helps the body absorb calcium, K2 ensures it’s directed to the bones not the arteries. Let’s explore some of the top-rated Vitamin D3 and K2 supplements available on iHerb, their key benefits, and what makes each one unique.

Why Vitamin D3 and K2 Matter

• Vitamin D3 (cholecalciferol): Boosts calcium absorption, strengthens bones, and supports immunity.

• Vitamin K2: Directs calcium to bones, prevents arterial calcification, and supports heart health.
