Why D3 + K2 together?

✓ D3 increases calcium absorption — but doesn't control where it goes

✓ K2 activates the proteins that direct calcium to bones and teeth

✓ Without K2, excess calcium can accumulate in arteries and soft tissues

✓ Together they support bone density, cardiovascular health, and immune function

✓ Clinically studied synergy — one is incomplete without the other

The Science Behind The Perfect Pair

Two vitamins that were made to work together — here's why.

D3: The Calcium Absorber

Without adequate D3, your body absorbs only 10-15% of dietary calcium. D MAX delivers 5,000 IU per capsule to maximize absorption.

K2: The Calcium Director

MK-7 activates osteocalcin and matrix GLA protein — directing calcium into bones and teeth while keeping it out of arteries.

Bone + Heart Protection

D3 and K2 together support bone mineralization while preventing arterial calcification — addressing two critical concerns as we age.

Immune + Mood Support

D3 activates immune cells and supports mood and cognitive health — benefits you get on top of the bone and cardiovascular synergy.

What our customers say

★★★★★

“I pair D Max with vK2 every morning. Simple routine, clean ingredients, and I've noticed my overall energy and mood have been more consistent since I started. Exactly what I was looking for.”

— Richard L.

★★★★★

“I have been taking vK2 along with my vitamin D3, and I recently had a calcium CT scan of my heart — the results showed zero percent detectable calcium buildup. In my book, that is exactly what one should expect.”

— Rosie Williams

★★★★★

“Top-notch quality on both products. The D3 dosage is perfect at 5,000 IU and the K2 uses both MK-4 and MK-7 forms. Buying the bundle just makes sense — these two should always be taken together.”

— Sam Freese

Frequently Asked Questions

Why should I take D3 and K2 together?

Vitamin D3 increases calcium absorption, but it doesn't control where that calcium goes. Without K2, excess calcium can accumulate in your arteries, kidneys, and soft tissues instead of your bones. Vitamin K2 activates the proteins that direct calcium to your bones and teeth — where it belongs — and away from your cardiovascular system. Taking D3 without K2 is only doing half the job.

Can I take both capsules at the same time?

Yes. D3 and K2 work synergistically and can be taken together. Both are fat-soluble vitamins, so we recommend taking them with a meal containing some fat (eggs, avocado, nuts, etc.) for optimal absorption.

Why 5,000 IU of D3? Is that safe?

Yes. 5,000 IU is a widely recommended daily dose for adults with vitamin D deficiency or insufficiency — which includes an estimated 42% of American adults. The Endocrine Society considers up to 10,000 IU daily safe for most adults. We recommend having your vitamin D levels tested and consulting your healthcare provider to determine the right dose for you.

What form of K2 is in vK2?

vK2 uses MK-7 (Menaquinone-7), the most bioactive and longest-lasting form of Vitamin K2. Unlike MK-4, which is cleared from the body within hours, MK-7 remains active for up to 72 hours — meaning a single daily dose provides around-the-clock calcium-directing support.

Is this safe with blood thinners?

If you take blood-thinning medications such as warfarin (Coumadin), consult your healthcare provider before taking Vitamin K2. Vitamin K can affect how these medications work. Your doctor can help determine the right approach for your individual situation.
