Discussion: Peak K2 is menatetrenone (MK-4), a form of vitamin K2 made in the body form phylloquinone (vitamin K1) and distinct from the menaquinones made by probiotic bacteria. Available science indicates that vitamin K2 — and especially menatetrenone — is superior to Vitamin K1. Clinical trials have shown that high-dose vitamin K2 does not cause excessive or abnormal blood clotting, although it will interfere with "blood thinning" medications.

Suggested Use

Adult Dosage: Take 1 capsule up to three times daily with food, or as directed by a qualified health care practitioner.

Other Ingredients

Microcrystalline cellulose.

Capsule: hypromellose.

Re: AOR Peak K2 - Excellent Product

Posted by 5355319119812756870 on Feb 17, 2017 | Verified Purchase

Hello, The "Peak K2" is excellent. I have been taking the 15mg. (2 caps. a day) of Menatetrenone for years. I have tried other brands over the years, but this one is the best. AOR has top quality products & you can't beat the price. I take this product because I have Osteoporosis. Since I live in Canada & we cannot get K2 in mg., even though the company AOR is located in Calgary. Puzzling! I do love that I can order it from iHerb.

Thanks for your feedback!
