What is Natural Factors Vitamin K2 120 mcg and what is it used for?
Natural Factors Vitamin K2 120 mcg is a vegan capsule supplement providing 120 mcg of MK-7 (menaquinone-7) per capsule, derived from natto (fermented soybean). It is used to support bone health by directing calcium into bones and teeth, and to support cardiovascular health by preventing calcium from depositing in arteries and soft tissues. One capsule provides 24-hour protection. 120 vegan capsules per bottle. NPN 80106329.
How does the MK-7 form of Vitamin K2 work, and why is natto the preferred source?
Vitamin K2 activates two key proteins: osteocalcin, which binds calcium into bone matrix, and matrix GLA protein (MGP), which inhibits calcium crystallisation in arterial walls. MK-7 (menaquinone-7) has a longer biological half-life than MK-4 — remaining active in the bloodstream for over 72 hours, compared to a few hours for MK-4 — allowing once-daily dosing at 120 mcg to maintain effective circulating levels. Natto-derived MK-7 is the form with the most consistent clinical evidence for raising serum K2 concentrations.
Who should take Vitamin K2 MK-7, and how should it be used?
Vitamin K2 MK-7 is particularly beneficial for adults over 40 with concerns about bone density or cardiovascular calcification, individuals taking vitamin D3 supplements (as D3 increases calcium absorption, K2 ensures it is directed properly), postmenopausal women at risk for osteoporosis, and adults with low natto or fermented food intake. Take one capsule daily with or without food. Consult a physician if taking blood-thinning medications (warfarin/Coumadin), as vitamin K can affect anticoagulation therapy.
What makes Natural Factors Vitamin K2 MK-7 stand out from other K2 supplements?
Natural Factors K2 uses natto-derived MK-7 at a 120 mcg dose, which is within the range used in clinical trials that demonstrated cardiovascular and bone benefits. The formula contains only MK-7 with no added MK-4, which avoids the confusion of mixed-form products whose ratios are often not clinically validated. Natural Factors products are ISURA-certified (screened for 800+ contaminants) and manufactured under TGA (Australian Therapeutic Goods Administration) standards — one of the most rigorous pharmaceutical manufacturing certifications globally. The B Corp certification adds environmental and social accountability.
What is Natural Factors, and is it a trustworthy supplement brand?
Natural Factors is a Canadian-owned supplement manufacturer founded in 1948 and headquartered in Coquitlam, British Columbia.

What is Natural Factors and is it a reliable Canadian supplement brand?
Natural Factors is one of Canada's largest supplement manufacturers, founded in 1955 by Jack and Rona Katz in British Columbia and still 100% Canadian family-owned. The company controls every production stage from raw material sourcing to finished product. Its facility holds TGA certification from Australia's Therapeutic Goods Administration, one of the world's strictest supplement manufacturing standards. All products are ISURA certified — independently tested for 800+ contaminants including pesticides and heavy metals — and Natural Factors conducts four rounds of product testing, double the industry average of two.
What sets Natural Factors apart from other supplement brands?
Natural Factors' most distinctive quality is vertical integration: the company grows its own raw herbs on 1,000+ acres of certified organic farmland in BC's Okanagan Valley, then processes and manufactures in-house. Most supplement brands source raw materials from external suppliers with no direct agricultural control. Natural Factors also uses ISURA third-party testing, a Canadian standard that screens for over 800 contaminants, well beyond typical heavy-metal panels. B Corp certification further reflects a documented commitment to environmental and social accountability, not just a marketing claim.
What makes Natural Factors different from other Canadian supplement manufacturers?
Natural Factors holds TGA certification from Australia's Therapeutic Goods Administration — one of the world's most rigorous pharmaceutical manufacturing standards, rarely earned by Canadian brands and far exceeding most North American certification requirements. Its ISURA testing program screens every product for 800+ contaminants, and it conducts four rounds of quality testing per product versus the industry standard of two. The company also operates its own farm in the Okanagan Valley for select botanical ingredients — a level of vertical integration uncommon among supplement manufacturers — and has been family-owned for over 70 years.
