Good vitamin k supplement
Verified Purchase
I like it. But be careful, this gives me a bad headache if I try to take it every day. Once a week and I'm fine.

Pair with d3 to strengthen bones
Verified Purchase
For bone and cardiovascular health, I started looking into vitamin K supplements. This product combines three forms—K1, K2-MK4, and K2-MK7—into a comprehensive formula. It's high in K1, and while the recommended daily intake of K2 isn't definitively established, this combination is designed to work synergistically. The 45-count pack is a good size, perfect for first-timers. iHerb's "bundled offer" also saved me money. After using it for a while, I feel it's a high-quality option worth sticking with.
