What Vitamin D3/K2 Does for Your Body

Corrects Vitamin D Deficiency†
Therapeutic 10,000 IU dose provides the potency needed to restore optimal vitamin D levels, especially critical for those with limited sun exposure, darker skin tones, or absorption challenges.†

Builds Stronger Bones†
D3 enhances calcium absorption while K2 activates osteocalcin, the protein that binds calcium into bone matrix, working together to support bone density and reduce fracture risk.†

Protects Cardiovascular Health†
K2 acts as your "calcium traffic cop," directing calcium to bones and teeth while keeping it away from arteries and soft tissues where it could cause problems.†

Supports Immune Function and Mood†
Vitamin D plays a critical role in immune system regulation and neurotransmitter production, helping support your body's natural defenses and promoting positive mood.†

Frequently Asked Questions

What is the optimal level of vitamin D?

Optimal levels of vitamin D have been hotly contested for decades, with “normal” being described by many physicians as anything above 30ng/dl. We recommend speaking to your qualified healthcare provider to find out what level is best for you based on your age, weight, and health history.

How can I find out my vitamin D levels?

If you’d like to have your vitamin D levels checked, all it requires is a simple and inexpensive blood test. Many doctors will order this test for you if you ask them to, and it is especially important to monitor your levels when you are taking higher amounts in an effort to raise your vitamin D to optimal levels.

When is the best time of day to take Vitamin D3/K2? Should it be taken with or without food?

Vitamin D3/K2 can be taken at any time of the day, morning or evening. Vitamin D3/K2 should always be taken with meals if possible as both vitamin D3 and vitamin K2 are fat soluble, and taking the formula with a meal will greatly improve its absorption.

    Took the vitamin D3 for six months because I was low on vitamin D and it brought my levels up 15 points.

    Love the product…need more to a bottle!

    My husband and I are very happy with our Vitamin D3 capsules, however, it would be wonderful if we could get a quantity choice. There’s so much extra room in the bottle, so it would be wonderful if we could get a 90 day/piece quantity option.
