The Science
Behind D3 + K2

Clinical study stat graphic for Vitamin D3 + K2

Why D3 Needs K2

Vitamin D3 increases calcium absorption from your gut. That’s great for bones, but here’s the problem: without K2, that calcium can deposit in your arteries instead of your bones.

K2 activates proteins that shuttle calcium into bones and teeth while preventing arterial calcification. Taking D3 without K2 is incomplete—you get bone benefits but miss cardiovascular protection.

How Our Formula Works

We use 5000 IU of vitamin D3, the dose recommended by many longevity researchers for optimal levels. The 100 mcg of K2 as MK-7 stays active in your body for 72 hours, compared to 8 hours for other K2 forms.

The coconut oil base increases D3 absorption by 50% compared to dry tablets. Both vitamins are fat-soluble, meaning they need dietary fat to absorb properly. We built it right into the formula.*

The Ingredients

Backed by research. Chosen for synergy. Proven to work.

Vitamin D3

(as Lanolin)

Vitamin D3 from lanolin is the same form your skin makes from sunlight. It’s more potent and longer-lasting than D2, raising blood levels of 25-hydroxyvitamin D more effectively.

See the research

Vitamin K2

(as MK-7)

MK-7 is the most bioavailable form of vitamin K2. It activates osteocalcin, which binds calcium to bone matrix, and matrix Gla-protein, which prevents arterial calcification.

See the research

Coconut Oil Base

We use coconut oil as the delivery system because D3 and K2 are fat-soluble vitamins. Without dietary fat, absorption can be as low as 10%.

Why do I need both D3 and K2 together?

Vitamin D3 increases calcium absorption from your digestive system. K2 activates the proteins that direct calcium to bones and teeth while keeping it out of arteries and soft tissues. Taking D3 alone could theoretically increase arterial calcification without K2 to manage calcium properly. That’s why vitamin D3 and K2 supplements are most effective when combined.

How long before I notice benefits from D3 + K2?

Most people report feeling more energetic within 2-4 weeks. Blood work typically shows improved vitamin D levels within 6-8 weeks. Bone density changes take 3-6 months to measure, though bone turnover markers improve within 8-12 weeks.

What’s the best time to take D3 + K2 softgels?

Take your softgel with your largest meal of the day. The dietary fat helps absorption of both vitamins. Morning or afternoon works equally well, just maintain consistency.

Can I take this if I’m on blood thinners?

Vitamin K2 can interact with warfarin and similar medications. Consult your healthcare provider before starting K2 supplementation if you take any anticoagulant medications. Your doctor may need to adjust your medication dose.

How do I know if I need vitamin D supplementation?

A simple blood test can measure your vitamin D levels. Optimal levels are between 40-60 ng/mL. Many people test below 30 ng/mL, especially in winter. Our AgingSOS panels include vitamin D testing.

Is 5,000 IU of vitamin D3 safe for daily use?

Research shows 5,000 IU daily is safe for most adults and often necessary to achieve optimal blood levels. The upper safe limit is 10,000 IU daily. People with certain medical conditions should consult their doctor.

What makes MK-7 better than other forms of K2?

MK-7 has superior bioavailability and remains active in your body for up to 72 hours. Other forms like MK-4 only last 8-12 hours. This means more consistent benefits with once-daily dosing.

Can I get enough D3 and K2 from food alone?

It’s challenging. You’d need 15-30 minutes of midday sun exposure for D3, which also differs between populations and latitudes. K2 is mainly in fermented foods like natto and aged cheeses that aren’t common in Western diets. Supplementation ensures consistent, adequate intake.
