Naka Platinum K2, Active MK-7 Form, 300 Capsules

Naka Platinum K2 Details

Naka Platinum K2 provides vitamin K2 in the active MK-7 form — the most bioavailable and longest-lasting form of K2 — in a generous 300-capsule supply. Vitamin K2 directs calcium to where it belongs (bones and teeth) and away from where it doesn't (arteries and soft tissue), making it a key partner to vitamin D and calcium for bone and heart health. The MK-7 form stays active in the body far longer than the shorter-acting MK-4 form, so a single daily dose maintains steady levels. Naka is a long-standing Canadian brand. A long-lasting standalone K2 to add to a vitamin D or bone routine.

Quick Facts

Who Naka Platinum K2 Is For

• Adults taking vitamin D and/or calcium who want K2 to help direct calcium to bones
• People focused on bone health and density, especially older adults and post-menopausal women
• Adults focused on cardiovascular wellness who understand the calcium-artery connection
• Anyone wanting a standalone high-quality K2 to add to an existing routine
• People wanting the longer-lasting MK-7 form rather than shorter-acting MK-4
• Adults wanting a very long supply (300 capsules) from a Canadian brand

Who this product is NOT for: If you take blood-thinning medication (warfarin/Coumadin), do NOT start vitamin K2 without your healthcare practitioner's guidance — vitamin K directly affects how these medications work, and this interaction is significant. If you want vitamin D and K2 combined in one product, see Naka Platinum D3+K2. If you want a Vitamart Exclusive K2 at a fair price, see Vitacheck Vitamin K2. If you want a complete bone formula rather than standalone K2, see AOR Bone Basics. If you have a clotting disorder, consult your practitioner before use.

Vitamart's Take

Naka Platinum K2 is a vitamin K2 supplement that supports bone and heart health. Vitamin K2 helps the body direct calcium toward the bones, which is why it's often taken alongside vitamin D and calcium. It uses MK-7, a long-lasting active form of K2, and the 300-capsule bottle gives an extended daily supply.

How Naka Platinum K2 Compares

Naka K2 vs Vitacheck Vitamin K2

Naka K2 (this product): MK-7 K2 with a very large 300-capsule supply, from a long-standing Canadian brand.
Vitacheck Vitamin K2: Natto-derived MK-7 from one of our Vitamart Exclusive brands at a fair price. A fit if you want Exclusive-brand value. See Vitacheck K2.

Naka K2 (standalone) vs D3+K2 Combined

Naka K2 (this product): Standalone K2 to add to your existing vitamin D. Dose K2 independently.
Naka D3+K2 Combined: Both vitamins in one softgel. A fit if you want the convenience of D and K2 together. See Naka D3+K2.

MK-7 vs MK-4 Forms

MK-7 (this product): Long-lasting, stays active in the body for days. One daily dose maintains steady levels.
MK-4: Shorter-acting, cleared within hours, requiring multiple daily doses. Usually synthetic. A fit only for specific practitioner protocols.

Vitamin K1 vs K2: What's the Difference?

Vitamin K comes in two main forms with different roles:

• Vitamin K1 (phylloquinone): Found in leafy greens. Primarily involved in blood clotting. Most people get enough K1 from diet.
• Vitamin K2 (menaquinone) — this product: Found in fermented foods and animal products. Primarily involved in directing calcium to bones and away from arteries. Most people get little K2 from diet.
• Why K2 specifically for bone and heart: K2 activates proteins (osteocalcin and matrix Gla protein) that bind calcium into bone and keep it out of arterial walls. This is the calcium-direction role that makes K2 valuable alongside vitamin D and calcium.
• The K2 dietary gap: K2 is found mainly in natto, certain cheeses, and organ meats — foods most North Americans eat little of. This is why K2 supplementation makes sense for many adults, even those eating plenty of leafy greens (which provide K1, not K2).

MK-4 vs MK-7: Why the Form Matters

Within vitamin K2, there are two main subtypes:

• MK-7 (this product): Long half-life — stays active in the body for days. A single daily dose maintains steady blood levels. The preferred form for most supplementation.
• MK-4: Short half-life — cleared within hours, requiring multiple daily doses. Usually synthetic. Used in some specific therapeutic protocols at much higher doses.
• Why MK-7 is generally preferred: Its long-lasting activity means convenient once-daily dosing and steady levels. For general bone and heart support, MK-7 is the practical, effective choice.
• Take with fat: Vitamin K2 is fat-soluble, so taking it with a meal containing some fat supports absorption.

How To Use

Adults: Take 1 capsule daily with food, ideally a meal containing some fat (vitamin K2 is fat-soluble), or as directed by your healthcare practitioner. Because MK-7 is long-lasting, one daily dose maintains steady levels.

Important: If you take blood-thinning medication (warfarin/Coumadin), do NOT start vitamin K2 without your healthcare practitioner's guidance. Vitamin K directly affects how these medications work. This interaction is significant and requires medical oversight. Talk to your practitioner before use if you have any clotting disorder or take any medication affecting blood clotting.
