MK-7 vs MK-4: Why the Form of Vitamin K2 Matters for Bone & Heart Health 💊
Two Vitamin K2 supplements can show the same dose on the label but your body may use them very differently.
The difference comes down to the form. 🌿
Vitamin K2 mainly comes as MK-4 or MK-7.
•MK-4 has a short half-life and clears from the body quickly.
•MK-7 stays active in the body much longer, helping maintain steadier levels with daily use.
But there’s another important detail most people never check…The source.
Naturally fermented MK-7 (commonly derived from natto) is predominantly the all-trans form, the biologically active form used in research.
That’s why the form and source of Vitamin K2 matters when choosing a quality supplement for bone mineralisation and cardiovascular health support.
Comment “SOURCE” and we will send you what to look for on the label.
