How to use

How

Take one softgel daily with a meal containing fat for best absorption.

When

Any time of day, ideally with your largest meal.

Dose

1 softgel

Notes

Consult your healthcare professional if you take blood thinners.

Why it matters

Better calcium absorption

D3 raises calcium absorption, while K2 (MK-7) activates the proteins that route that calcium into bone rather than soft tissue.

Synergistic dosing

5,000 IU D3 paired with 200mcg K2 follows peer-reviewed ratios shown to elevate 25(OH)D serum levels effectively.

Bioavailable forms

We use cholecalciferol (D3) and MK-7 K2 — the forms your body uses most efficiently, with a longer half-life than MK-4.

Got questions? We have answers.

Why combine D3 with K2?

Vitamin K2 directs calcium absorbed with D3 into bones and teeth rather than arteries. The combination is more effective than D3 alone for bone health and cardiovascular support.

What form of D3 do you use?

We use cholecalciferol (D3), the same form your skin produces from sunlight. It raises blood levels of 25(OH)D more effectively than D2.

Can I take this every day?

Yes. Follow the dosage on the label. If you take blood thinners or have a medical condition, consult your healthcare professional first.

Is this product third-party tested?

Every batch is tested by accredited third-party laboratories for potency, purity, heavy metals, and microbial contaminants.

5,000 IU Vitamin D3 (cholecalciferol) paired with 200mcg Vitamin K2 (MK-7) for optimal calcium absorption and bone mineralization. Peer-reviewed dosing protocol. Tested for 25(OH)D serum elevation in clinical setting.
