Vitamin K2

Please note, this OEL/ADE monograph also applies to Vitamin K2 (menaquinone-4) (CAS RN 863-61-6). Menaquinone-7 (MK-7) (CAS 2124-57-4) and menaquinone-4 (MK-4) (CAS 863-61-6), also known as menatetrenone, are forms of vitamin K2. Vitamin K represents a family of fatsoluble compounds with the common chemical structure of 3-substituted 2-methyl-1,4- napthoquinone. It naturally occurs in food as phylloquinone (vitamin K1) and menaquinones (vitamin K2). Menaquinones are a group of compounds with an unsaturated sidechain from 4 to 13 isoprenyl units (vitamin K2 or MK-n) and are found mainly in animal products such as meat, cheese and eggs (2, 6). The number of these units is given as a suffix(-n), they are named MK-4 to MK-13. It should be also pointed out that there can be differences between natural and synthetic vitamin K2, as was demonstrated in the case of MK-7, for which the synthetic mono-cis form (2Z) was inactive or had little activity compared with the natural all- E form.

Affygility Solutions has an occupational exposure limit (OEL) and control band assignment for this active pharmaceutical ingredient (API). This monograph also contains the acceptable daily exposure (ADE) value.
