Description

Vitamin K & D features vitamin K2 as menaquinone-7 (MK-7), an advanced, fat-soluble form of vitamin K that serves multiple functions in the body. The K family consists of a trio of vitamins: K1 (phylloquinone), found naturally-occurring in leafy green vegetables and plant oils; K2 (menaquinone) which is present in butter, cows liver, eggs, certain cheeses and natto, a fermented soybean food; and K3, a synthetic form of the vitamin. Only K2 in the form of MK-7 has been shown to offer 24-hour protection from a single daily dose. Other commercially-available subtypes of K2, such as MK-4, only last four to six hours in the body and are required in much larger dosages to be effective.

Vitamin D has long been considered a classic nutrient for bone metabolism. It supports bone development and is needed for calcium absorption. Vitamin K & D uses vitamin D3 (cholecalciferol), a natural form of vitamin D that is safer and more biologically active than D2 (ergocalciferol), a synthetic form of vitamin D. 

Vitamin D is required for the absorption of minerals such as calcium while vitamin K is needed to direct the minerals to the right place, preventing an inappropriate calcification of soft tissues. Likewise, cells only produce osteocalcin and the matrix Gla protein (MGP) in the presence of vitamin D, but vitamin K is necessary to activate those proteins to do their jobs. There is even evidence to suggest that the safety of vitamin D is dependent on adequate vitamin K and that vitamin D toxicity (which is extremely rare with the D3 form) is actually an induced deficiency of vitamin K2.

Notes

Doses of vitamin K2 over 45 mcg daily may negatively interact with oral anticoagulant therapy.
Patients receiving blood thinning medications (warfarin) should not take vitamin K without consulting their health care practitioner.

Although there have been reports of toxic effects from vitamin D supplementation, the question of safety surrounding vitamin D ultimately boils down to the type of vitamin D used. In all known cases of vitamin D toxicity where the dose was intentional (as opposed to accidental overdose) the form used was D2, a synthetic form of vitamin D.

There has never been a published report of toxicity resulting from intentional doses of vitamin D3. Natural Factors only uses the naturally-occurring D3 form of vitamin D.
