High quality product definitely recommend!
Why did you pick this product vs others?: I've been using Thorne K Vitamin alongside my Vitamin D supplement, and I couldn't be happier with the results. The quality of this product is top-notch, which is exactly what I expect from Thorne. It’s been a great addition to my daily routine, and I really appreciate that it complements my Vitamin D to maximize absorption and effectiveness. I’ve noticed a positive difference in my overall health since incorporating it, and I feel more energized. If you're looking for a reliable Vitamin K supplement, I definitely recommend giving Thorne a try. You can trust the quality and feel confident in your purchase!

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.
