Jarrow Formulas MK-7

Bone and cardiovascular support through Vitamin K2 supplementation.. Jarrow is a top-tier brand and this MK-7 is a clean source. But 90mcg is a maintenance dose. Most clinical trials for bone density and arterial health use 180mcg to 200mcg. You will likely need to double the serving to see the best results.

7.0/10
VERY GOOD

You are getting a high quality source of MK-7, but the dose is better for maintenance than for therapeutic results.
