Vitamin K2 (MK-7) Powder Technical Data Sheet
Vitamin K includes two natural vitamers: vitamin K1 and vitamin K2. Vitamin K2, in turn, consists of a number of related chemical subtypes, with differing lengths of carbon side chains made of isoprenoid groups of atoms.
Vitamin K1, also known as phylloquinone or phytomenadione, is made by plants, and is found in highest amounts in green leafy vegetables because it is directly involved in photosynthesis. It may be thought of as the plant form of vitamin K. It is active as a vitamin in animals and performs the classic functions of vitamin K, including its activity in the production of blood-clotting proteins.
Vitamin K2 (menaquinone) includes several subtypes. The two most studied ones are menaquinone-4 (menatetrenone, MK-4) and menaquinone-7 (MK-7).

| Name |
Phylloquinone (single substance) |
Menaquinone (a family of similar molecules called

often consumed in food.) |
| Function |
Blood clotting – prevents excessive bleeding. (K1 is what prevents a paper cut from becoming dangerous.) |
Helps direct calcium to the right places (into bones
and teeth and out of soft issues like arteries and
kidneys)
May help support bone, heart and brain health. |
| Found in |
Green leafy vegetables |
Fermented foods (some European hard cheeses

| Toxicity |
No known toxicity if taken at recommended levels. |
No known toxicity if taken at recommended levels. |
| After taking |
Vitamin K1 travels to liver more effectively than to bones.
Liver uses Vitamin K1 to activate proteins needed for blood clotting. |
Vitamin K2 travels to bone more effectively than K1.
Bones use K2 to produce Osteocalcin, a bone-
building protein hormone, which also supports
metabolic health.
The MK-4 form of Vitamin K2 is effective at
reaching tissues other than liver and bones.
The MK-7 form of K2 is 3X better at reaching
bones and activating Osteocalcin than K1. |
