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.

This potassium supplement is great, especially because it's a softgel, which is better absorbed by the body, but the dosage of K2-MK7 is very low, and it's a bit expensive. The ingredients are of excellent quality. But I'm switching to another one. The price of this supplement has gone up a lot.

A good product. I liked the composition and ingredients—everything is clear, without unnecessary additives. The quality is high, the packaging is sturdy. The capsules are conveniently sized and easy to swallow. The dosage is optimal; no need to count. With regular use, the overall health benefits are noticeable. I will order more.
