Vitamin K2 as MK-7 (menaquinone-7) has the longest half-life of any vitamin K form — circulating in the bloodstream for several days after a single dose. This makes it well suited to once-daily supplementation and helps maintain steady vitamin K status between doses.
The all-trans configuration is the biologically active form of MK-7. Some MK-7 ingredients contain a mixture of the active all-trans form and the inactive cis form; our K2 is sourced as all-trans only, so the full labelled dose is in the form the body can use.
