Customers Also Ask:

1. What is vitamin D3?

Vitamin D3 is a form of vitamin D that your body naturally makes when your skin is exposed to sunlight, and it’s also found in certain foods such as fatty fish, eggs, and fortified dairy products. It’s a fat-soluble vitamin that plays an important role in how your body functions.

Vitamin K2 is a form of vitamin K found in foods such as fermented products like natto and certain cheeses

3. Why is it better to take D3 and K2 together?

A growing body of evidence suggests a synergistic effect of vitamin K combined with vitamin D. Vitamin D promotes the production of vitamin K-dependent proteins that play a key role in various functions in the body. While research is ongoing, vitamin D has strong clinical backing for immunity and bone health support.*

3. Does vitamin D help calcium absorption?

Yes, vitamin D helps your body absorb calcium from the foods you eat by increasing intestinal absorption.
