Proven Vitamin D3 Benefits

Vitamin D is widely studied for all kinds of health benefits, like bone health, calcium absorption, heart health, and immunity.

When you take vitamin D, you lower your chances of getting sick from viral infections, like colds and the flu, by at least 10 percent. But people who are deficient in vitamin D actually see a greater protective benefit when they supplement, reducing their risk by 50 percent. 

What doesn’t change, however, is the immune system’s reliance on vitamin D levels, making it a more secure way to boost immunity.
