Vitamin D3 + K2
Most adults living and working indoors are quietly deficient in vitamin D — and that deficiency contributes to low mood, fatigue, and weakened immunity in ways that are frequently mistaken for burnout. But getting enough D3 is only half the job. Without K2 (MK-7), the calcium vitamin D mobilises has no direction — and calcium that ends up in arterial walls instead of bones is a problem, not a benefit. 5,000 IU D3 paired with K2 (MK-7) and BioPerine®. The complete job, done properly.

What to expect
The honest timeline.
Most people who don't see results stopped too early. Here's what consistent use actually builds — week by week.
More stable energy and mood
The first thing most people notice.
D3 plays a direct role in serotonin production and immune regulation. Restoring depleted levels often shows up first as steadier energy and a more even mood baseline — especially through low-sunlight months.
Stronger physical foundation
Calcium finally going where it should.
Bones, joints, and connective tissue all depend on calcium being properly absorbed and directed. D3 drives the absorption. K2 handles the direction. The combination does what neither does alone.
Cardiovascular confidence
The protection most D3 supplements skip.
K2 (MK-7) actively prevents calcium from depositing in arterial walls — a risk that increases with high-dose D3 supplementation without K2. This formula is designed with that in mind.
Long-term resilience that compounds
Most apparent when you look back.
D3K2 works on a foundational level. The benefits build quietly — and become most apparent when you look back at how you felt six months ago. Consistency is the only variable that matters here.
Questions you might have
Honest answers.
-
Yes — and we'd encourage it. The D3K2 formula is designed to work alongside the Complete Multivitamin without overlapping in a way that creates excess. If you're taking a third-party multivitamin, check its D3 content — combined with 5,000 IU from this formula, most people will be well within a safe and effective range, but it's worth being aware of your total daily intake.
-
For most adults with genuine D3 deficiency — which research suggests is the majority of people living and working indoors — 5,000 IU is an appropriate therapeutic dose. The inclusion of K2 (MK-7) is specifically what makes high-dose D3 safe for long-term use by ensuring calcium is properly directed. If you have a known medical condition or are taking medications that affect calcium or vitamin D metabolism, check with your doctor first.
-
Calcium alone has poor absorption without D3 to facilitate it. D3 alone at high doses increases calcium in the bloodstream without guaranteeing it goes to bones — which is where K2 becomes essential. This formula is built around the understanding that these three nutrients work as a system, not independently. Taking them together is meaningfully more effective than taking any one of them in isolation.
-
Vitamin D toxicity is real but rare, and typically occurs at sustained doses well above 10,000 IU daily over extended periods. At 5,000 IU with K2 included, this formula is designed for adults with genuine deficiency who need a therapeutic rather than maintenance dose. If you want certainty, a simple blood test (25-OH vitamin D) before and after 90 days will show you exactly where your levels are and whether the dose is right for you.
90 days to feel the difference — or your money back.
D3K2 works on a foundational level. The most meaningful changes — in energy, mood stability, bone strength, and cardiovascular health — build over weeks and months of consistent use, not days.
That's why we give you 90 days. Enough time to actually experience what a properly formulated D3K2 does when taken consistently.
If you don't feel it's making a difference, contact us and we'll make it right — no complicated process, no awkward questions.
