KEY FUNCTION

ENHANCED ABSORPTION

Vitamin D3 (Cholecalciferol) 5,000 IU
Hormonal D Precursor
Vitamin D3 (Cholecalciferol) 5,000 IU

WHAT IS IT?

Cholecalciferol, the form of vitamin D your skin actually makes from sunlight. Fat-soluble, active once hydroxylated by the liver and kidney.

HOW IT HELPS

Supports bone density, immune function, mood, and hundreds of downstream processes that depend on adequate vitamin D status.

THE SCIENCE

5000 IU per day reliably raises serum 25-OH-D into the optimal 50 to 80 ng/mL range for most adults, the window associated with strongest health outcomes in observational data.

OUR SOURCE

Lanolin-derived D3, USP-tested for potency, stabilized in a lipid carrier.

Vitamin K2 (MK-7) 100 mcg
Calcium Placement Director
Vitamin K2 (MK-7) 100 mcg

WHAT IS IT?

Menaquinone-7, the longest-acting form of vitamin K2. Derived from natto fermentation. Directs calcium to bone and away from soft tissue.

HOW IT HELPS

Completes the D3 stack. D3 brings calcium into circulation, K2 puts it where it belongs. Without K2, the benefit of high-dose D3 is incomplete.

THE SCIENCE

MK-7 has a 72-hour half-life vs MK-4's short half-life. Trials at 90 to 180 mcg per day show measurable support for bone turnover markers and arterial flexibility.

OUR SOURCE

All-trans MK-7 from fermented natto, cis-isomer minimized, HPLC-verified potency.

Virgin Sunflower Seed Oil
Fat Carrier For Vitamins
Virgin Sunflower Seed Oil

WHAT IS IT?

Cold-pressed high-oleic sunflower oil. The lipid vehicle that makes D3 and K2 actually absorb.

HOW IT HELPS

D3 and K2 are fat-soluble. Without a proper lipid matrix, absorption is unreliable. Sunflower oil solves that cleanly.

THE SCIENCE

Controlled studies show dry-powder D3 absorbs less consistently than oil-dispersed D3. A lipid carrier is the clinical standard.

OUR SOURCE

High-oleic, non-GMO, cold-pressed sunflower oil, oxidation-stability tested.

Why D3 K2?

5,000 IU + 100mcg K2. Bone, Immunity, Mood.

Experience D3 paired with K2 in a single soft gel, the vitamin duo built to route calcium into bones, not arteries, and support year-round immune tone.

They Felt The Difference. So Will You.

5.0 stars

Winter mood, finally fixed

I live in Seattle. Every November I would crash. Started 5000 IU in September last year and made it through winter feeling stable for the first time ever.

Steady Energy Daily Wellness
5.0 stars

The pairing is the difference

Was on standalone D3 for years. Added K2 and within a month my annual bloodwork showed better calcium signaling. My doctor asked what I changed.

Deeper Sleep Morning Energy
5.0 stars

Energy, without stimulants

Did not realize I was deficient until I fixed it. Mornings are brighter, afternoons hold steady, workouts feel cleaner. All from one soft gel.

Visible Glow Stronger Nails
5.0 stars

Bone density markers improved

Mid-forties, started getting worried about long-term bone health. Twelve months in, DEXA scan moved in the right direction. Not proof, but the timing is telling.
