Liquid Vitamin D3 + K2

Thorne's Vitamin D/K2 contains vitamin D3 and vitamin K2 MK-4 in liquid form.

Each drop contains 100 mcg of vitamin K2 MK-4 (the most clinically researched form of vitamin K) and 12.5 mcg of vitamin D3.

This balanced dosage makes it possible to use this product for both low dosages (1 drop per day) and higher dosages.

And drops are an easy way to ensure adequate intake of both vitamin D3 and vitamin K2 MK-4.

Why D3 and K2?

Vitamin D3 and K2 work together to promote bone health and a healthy immune system. Maintaining optimal vitamin D levels throughout all stages of life contributes to strong bones and a healthy immune system. The addition of vitamin K2 helps transport calcium from the blood vessels to the bones. The combination of vitamin D3 and K2 offers more benefits than each taken individually.
