Excellent Vitamin K supplement
A tad pricey, but made in in a US GMP facility and lot tested. It seems to be more effective that other VitK supplements that I've used in the past. I recommend it. Rated 4 stars because of pricing.US GMP manufacturing with lot analysis QA.

For bone health
I got this for my bone health. I take it along with my cal/mag, boron. and d-3. I have no way of knowing if it's helping, but I feel that at least it's proactive, and worth adding to my other supplements.
