Supports a healthy heart and blood circulation.
Promotes bone health and calcium absorption.
Benefits immune function.
Thorne’s Vitamin D + K2 Liquid combines these two powerful vitamins to enhance bone health, cardiovascular support, and immune function. Maintaining optimal vitamin D levels throughout life is crucial for strong bones and a robust immune system. Adding vitamin K2 ensures that calcium is effectively directed to the bones, helping to protect soft tissues, such as the arteries and kidneys, from harmful calcification. The combination of vitamins D3 and K2 provides greater benefits together than either vitamin offers alone.
This formula includes MK-4, the most clinically studied form of vitamin K. The vitamin D is in its D3 form, which is more potent and better absorbed than D2. With these vital nutrients, you’re investing in a healthier future for your bones, heart, and overall wellbeing.
