Peak K2** 90 Veggie Caps


Peak K2 is menatetrenone (MK-4), a form of vitamin K2 made in the body from phylloquinone (vitamin K1) and distinct from the menaquinones made by probiotic bacteria. Available science indicates that vitamin K2 – and especially menatetrenone – is greater than Vitamin K1 in maintaining the health of the bones and vascular system. Clinical trials have proven that high-dose vitamin K2 does not cause excessive or abnormal blood clotting, although it will interfere with “blood thinning” medications.

ADULT DOSAGE: Take one to three capsules daily with food, or as directed by a qualified health care practitioner.

Main Applications
As reported by literature:
• Bone health
• Brain health
• Cardiovascular function

Solanesol (from Nicotiana tabacum).

Pregnancy / Nursing
Do not use.

• Clinical trials have documented that menatetrenone does not induce hemostatic activation. However, it will interfere with the activity warfarin (Coumadin®) and possibly other anticoagulant ("blood thinning") medications. Patients prescribed anticoagulants must not take this supplement.



Vitamin K is an essential nutrient, best known for its role in blood clotting. Plants make one form of vitamin K (phylloquinone, or vitamin K1) for their use. But your body doesn't use all of the K1 in your diet "as is." Instead, the body converts some of this plant form of the vitamin into a different vitamin K molecule: Menatetrenone, or MK-4, a form of vitamin K2. Tissues vary in their vitamin K needs, and it's become clear that some tissues have a specific need for Menatetrenone, which is not met by phylloquinone. For some purposes (like blood clotting), phylloquinone works fine; but extensive evidence shows that Menatetrenone has unique effects on bone health not shared by phylloquinone.

•Fracture victims' levels of Menatetrenone are more depressed than are their levels of phylloquinone.
•Areas where more K2 is consumed in the diet have lower fracture rates.
  • Menatetrenone inhibits the resorption (teardown) of bone caused by the local cellular messenger prostaglandin E2 (PGE2). The same concentration of phylloquinone has no effect.
  • Menatetrenone also cuts down on the bone cells' formation of PGE2 in the first place.
  • Menatetrenone is able to reduce the creation of osteoclasts (cells involved in the teardown of bone tissue) out of early cell types - but again, phylloquinone has no such power.
  • Menatetrenone, but not phylloquinone, actually increases the programmed cell death ("apoptosis") of existing osteoclasts.
  • Menatetrenone strengthens the bone-building legions of the osteoblasts (cells involved in the manufacture of new bone), mildly increasing both their numbers and their activity.

Over the course of the last decade, at least sixteen clinical trials have been performed using Menatetrenone, and every single one has found that K2 supplements protect bone health. Menatetrenone not only slows, halts, or even reverses loss of bone mass: it dramatically reduces your risk of suffering a fracture.

The ability of bones to withstand fractures is not just determined by the quantity of bone (as measured by Bone Mineral Density (BMD)), but also by the quality of bone - bone "microarchitecture," including especially "trabecular connectivity." Evidence suggests that Menatetrenone's most important effects are on bone quality, not bone quantity.

•Clinical trials have found that Menatetrenone provides as much protection against fracture as drugs that have much more powerful effects on BMD. Clearly, Menatetrenone's bone-protective effects extend to aspects of bone health beyond the BMD numbers.
•Menatetrenone provides powerful protection against the loss of trabecular connectivity in laboratory animal models of menopausal osteoporosis.
•Menatetrenone supplements increase bone quality in young, healthy animals.

To get the amount of Menatetrenone used to produce these effects in clinical trials and experimental studies requires a specific Menatetrenone supplement.

•Existing science shows that phylloquinone does not provide the same benefits as Menatetrenone. No clinical trials using phylloquinone supplements have been performed to show reduced fracture risk.
•The body's ability to convert phylloquinone into Menatetrenone is limited, flattening out at levels far below what's used in clinical trials. This ability is further reduced with aging.
•Very little vitamin K2 exists in the diet, even in the richest food sources.
•While the body's friendly bacteria produce some K2, little or none of this K2 is absorbed.

Menatetrenone's health benefits extend well beyond the skeletal system. Emerging science is now documenting the role of vitamin K - and specifically of Menatetrenone - in protecting our cardiovascular health, and the health of that all-important organ, the brain.
