This is my second time purchasing THORNE’s Vitamin K, and I’m really happy with the quality. I trust Thorne as a brand, and this supplement feels like it’s making a difference in my overall health.

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.

Doctor recommended
This was rx by my doctor. They're kind of spendy, but necessary for bone health.
