Frequently Asked Questions
Why combine D3 and K2 in the same formula?
Vitamin D3 helps your body absorb calcium from food. That's the well-known part. Here's what most people don't know: without vitamin K2, that extra calcium can end up in the wrong places — like artery walls instead of bones. K2 acts as the "traffic director," guiding calcium into your bones and teeth where it belongs, and helping keep it out of soft tissues and blood vessels. Together, they work as a team. Separately, each is incomplete.
What's the MK-7 form of K2 — and why does it matter?
Our formula uses 90 mcg of K2 as MK-7 (menaquinone-7), plus 20 mcg as phytonadione. MK-7 is a longer-lasting form of K2 found naturally in fermented foods like natto. Because it stays active in the body longer than other forms, smaller doses are needed to achieve meaningful levels. It's the preferred form in most clinical research on K2 and bone health.
Is 2,000 IU of D3 too much — or not enough?
2,000 IU is a well-supported daily dose for most adults. It's above the outdated minimum RDA (600 IU) but well below the upper tolerable limit (4,000 IU for general use). The U.S. Dietary Guidelines recommend at least 800 IU for adults over 50. For most people who aren't getting regular sun exposure — which includes the majority of Americans — 2,000 IU is a practical, safe daily amount.
I take warfarin — can I still take this?
This formula contains vitamin K, which can interact with warfarin (Coumadin) and other anticoagulant medications. If you take blood thinners, please consult your doctor before adding this supplement. This is a genuine interaction — not a blanket disclaimer.
How long does it take to work?
Vitamin D levels in the blood typically take 4–6 weeks to meaningfully rise with consistent daily supplementation. For bone density changes, studies show results over months to years of consistent use. This is a long-term investment in your health — not a quick fix. Small steps, consistent habits.
