Vitamin K2

别名: menaquinone, MK-7

Vitamin K2 activates proteins that bind calcium into bone and take part in blood clotting. It is found in fermented foods (natto, cheese); the long-acting MK-7 form stays in the blood longer than K1.

用途

Maintenance of normal bones and blood clotting – strong evidence for the role of vitamin K (EFSA)
Lower fracture risk – weak to moderate, inconsistent evidence
Slowing vascular calcification – weak evidence

剂型及区别

MK-7

long half-life, once daily is enough; most common supplement form

MK-4

short half-life, studies used high doses

K2 with D3

common combination; check the vitamin D dose on the label

form not stated

the manufacturer should state whether it is MK-7 or MK-4

何时服用

With a meal containing fat, can be taken together with vitamin D.

适合搭配

Vitamin D3, calcium, magnesium.

不宜同服 / 需错开

Do not combine with warfarin-type medicines without consulting your doctor.

注意事项

If you take warfarin-type blood thinners (vitamin K antagonists), vitamin K changes their effect – use it only after agreeing with your doctor. With other blood thinners, in pregnancy and with liver disease also consult your doctor.

安全性

EFSA has not set an upper limit; do not exceed the label dose.

实用建议

If you take vitamin D above 2000 IU, adding K2 is a reasonable choice – though not yet backed by clear evidence.
