D3 5000 + K1&K2 bottle
D3 POTENCY
5,000 IU cholecalciferol

Clinical dose of D3.

5,000 IU is the daily intake many functional practitioners use to move serum 25(OH)D into the optimal 50–80 ng/mL range — particularly for patients with limited sun exposure or VDR-related polymorphisms.

K2 DIRECTION
MK-7 K2VITAL® menaquinone

Where calcium belongs.

Vitamin K2 as MK-7 activates osteocalcin and matrix GLA protein — the proteins that shuttle calcium into bone matrix and keep it out of arterial walls. The most bioactive menaquinone form available.

ABSORPTION
1 liquid capsule with olive oil

Fat-soluble, fully absorbed.

D3 and K vitamins are fat-soluble — they require dietary fat for uptake. The olive oil liquid capsule delivers the fat matrix at the capsule level, improving absorption over dry-powder vitamin D products.

MAY BENEFIT

Bone and artery,
same chemistry.

01
Bone density
D3 and K2 together direct calcium into bone matrix through osteocalcin activation — the framework behind skeletal strength.
02
Arterial flexibility
Vitamin K2 activates matrix GLA protein, which keeps calcium from depositing in arterial walls and cardiac valves.
03
Immune resilience
Vitamin D3 modulates both innate and adaptive immune response — a foundational nutrient for immune stability through every season.
04
Mood & seasonal balance
Low serum vitamin D tracks with low mood, seasonal fatigue, and disrupted circadian signaling in much of the population.
05
Hormone support
D3 functions as a prohormone — supporting thyroid, parathyroid, and reproductive endocrine balance at adequate serum levels.
06
Boron-enhanced action
Boron citrate extends vitamin D's half-life in circulation and supports the conversion of D3 into its active 1,25-dihydroxy form.

Formula

Four fat-soluble nutrients. One daily liquid capsule.

Questions

Frequently asked.

Why combine D3 with K2?
D3 increases intestinal calcium absorption — but without adequate K2, that extra calcium can deposit in soft tissue and arterial walls. K2 activates the proteins that direct calcium into bone and keep it out of the vasculature. Taking D3 without K2 can be counterproductive for long-term cardiovascular health.
Is 5,000 IU of vitamin D too much?
5,000 IU is a common functional-medicine daily dose and generally well-tolerated. If you have a known vitamin D deficiency or insufficiency, it's used for repletion; if your 25(OH)D is already in the optimal range, a lower dose may suffice. Test serum levels every 6–12 months with your practitioner.
Why the liquid capsule format?
Vitamin D3, K1, and K2 are fat-soluble — they absorb meaningfully better when delivered in a fat matrix. The olive oil liquid capsule provides that matrix at the point of ingestion, unlike dry-powder D3 products that rely on whatever fat is in your meal.
Can I take this if I'm on blood thinners?
Vitamin K can interact with warfarin (Coumadin) by supporting clotting-factor synthesis. If you are on warfarin or another vitamin K-dependent anticoagulant, consult your healthcare provider before starting. Many patients on these medications require specific INR monitoring if they add K-containing supplements.
What does boron do in this formula?
Boron citrate extends the circulating half-life of vitamin D and supports its conversion into the active 1,25-dihydroxyvitamin D form. It also plays a role in bone matrix density and hormone metabolism — a small but meaningful addition to the D3/K stack.
Who is this formula designed for?
Adults focused on bone density, cardiovascular calcium handling, immune resilience, or mood stability. Particularly useful for patients with limited sun exposure, darker skin tones, osteoporosis risk, or VDR-related genetic variants that affect vitamin D utilization.

Methylation and the immune system: how one cycle shapes inflammation

The methylation cycle is not just a mood and detox system — it quietly regulates how your immune cells turn on, turn off, and resolve inflammation. Here's the connection.
