Vitacheck Vitamin K2 100mcg, Natto-Derived MK-7, Supports Bone and Heart Health, 150 Vegetable Capsules

Vitacheck Vitamin K2 100mcg Details

Vitacheck Vitamin K2 delivers 100 mcg of natto-derived MK-7 — the most bioavailable and longest-lasting form of vitamin K2 — per vegetable capsule. 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, derived from natto (fermented soybeans), stays active in the body far longer than the shorter-acting MK-4 form. One of our Vitamart Exclusive brands, delivering practitioner-quality K2 at a fair price. 150 vegetable capsules — a generous 5-month supply. Made in Canada.

Quick Facts

Who Vitacheck Vitamin K2 Is For

• Adults taking vitamin D and/or calcium who want K2 to help direct calcium to bones rather than arteries
• People focused on bone health and bone 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 vitamin D routine
• People wanting the longer-lasting MK-7 form rather than shorter-acting MK-4
• Adults wanting practitioner-quality K2 at a fair price from a Vitamart Exclusive brand, with a generous 5-month supply

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 Vitacheck Vitamin D3+K2. If you have a soy allergy, note that MK-7 is derived from natto (fermented soybeans) — though the final product typically contains negligible soy protein, those with severe soy allergies should consult their practitioner. If you want K2 in liquid drops, see Vitacheck D3+K2 Liquid Drops.

Vitamart's Take

Vitacheck Vitamin K2 is one of our Vitamart Exclusive brands, delivering 100 mcg of the premium natto-derived MK-7 form at a fair price. Here's why K2 matters: vitamin D helps your body absorb calcium, but it's vitamin K2 that directs that calcium to your bones and teeth (where you want it) rather than your arteries and soft tissue (where you don't). This is why K2 is increasingly recommended alongside vitamin D and calcium. The MK-7 form is the one to want — it stays active in the body far longer than the shorter-acting MK-4 form, so a single daily dose maintains steady levels. The sensible choice for adults who take vitamin D or calcium and want to add standalone K2 for proper calcium direction. With 150 capsules, this is a generous ~5-month supply. If you'd prefer D3 and K2 together in one product, Vitacheck Vitamin D3+K2 combines both. One important note: if you take blood thinners like warfarin, talk to your practitioner before starting K2 — the interaction is significant.

How Vitacheck Vitamin K2 Compares

Vitacheck K2 (standalone) vs Vitacheck D3+K2 Combined

Vitacheck K2 (this product): Standalone K2 to add to your existing vitamin D. Flexible — dose K2 independently of D.
Vitacheck D3+K2 Combined: Both vitamins in one softgel. A fit if you want the convenience of D and K2 together and don't already take vitamin D separately.

Vitacheck K2 vs Other MK-7 Brands

Vitacheck K2 (this product): 100 mcg natto-derived MK-7, Vitamart Exclusive brand at a more accessible price. Generous 150-capsule supply.
Other MK-7 Brands (Prairie Naturals, Naka, Biomed): Similar MK-7 form from established brands. A fit if you prefer a specific brand. Vitacheck delivers the same MK-7 quality at a Vitamart Exclusive price.

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. Natto-derived.
MK-4: Shorter-acting, cleared from the body 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 (fermented soybeans), 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): Derived from natto (fermented soybeans). 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: Usually synthetic. Short half-life — cleared within hours, requiring multiple daily doses to maintain levels. 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.
• Natto source: MK-7 is produced through the fermentation of soybeans into natto. The supplement extracts the MK-7, typically leaving negligible soy protein — but those with severe soy allergies should consult their practitioner.

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.
