Douglas Laboratories® Vitamin K2

Vitamin K2, manufactured by Douglas Laboratories ®, supplies a significant amount of biologically active vitamin K2 in the form of soy-free menaquinone-7 (MK-7).


This is derived from geraniol and farnesol. Geraniol is the primary part of rose oil, palmarosa oil and musk. This nature-identical form of menaquinone-7 is extensively tested for molecular identity and bioequivalence when compared to menaquinone-7 from fermented soy beans(natto). This version is the all-trans form, thus providing a pure, biologically active form.

Vitamin K Functions

Vitamin K2 (as MK-7) supports bone and cardiovascular health, and is more bioactive than vitamin K1 and other menaquinones. Vitamin K was first discovered as the anti-hemorrhagic factor, however now it encompasses a variety of physiological processes. Other than blood clotting Vitamin K plays a role in bone and cardiovascular conditions by aiding in calcium utilization. Vitamin K is needed to activate osteocalcin (carboxylated), which functions to take calcium out of the vessels and deposit them into the bones. Therefore, consuming sufficient amounts of dietary calcium is not enough for bone and cardiovascular health; the body needs to distribute and utilize the calcium properly with aid of Vitamin K. †

Sources of Vitamin K

The major source of vitamin K in most diets is phylloquinone (vitamin K1), which is present in green leafy vegetables such as spinach, broccoli, and kale. Vitamin K2 is present in small amounts in fermented foods, milk products, cheese, and meat, and is synthesized by various human gut microbiota.
