Source Naturals Vitamin K2 -- 60 Tablets

Supports Bone Health. 100 MCG - 60 TABLETS Vitamin K2 is a more biologically active form of Vitamin K extracted from a fermented Japanese soyfood called natto, a powerhouse of nutrients. Fat-soluble, it is an essential cofactor for the production of proteins that bind calcium - supporting cardiovascular and bone health. Vitamin K2 is more efficient than K1 because it remains in circulation longer and is active in more tissues. Contains milk/dairy and soy.

"I am convinced that this is the best form (natto extracted K2) of K available. The only downside is the cost compared to the lab made K1."

"This product contains good amounts of vitamin D, and a good version of vitamin K. But the amounts of vitamin K are microscopic for the use I needed - cardiovascular amounts are around 20 mg, I understand, but this measures in micrograms. I think it is sort of mislabelled and should be called vitamin D with a dash of K2 instead of vitamin K2. I am going back to vitamin D only tabs, until a vitamin K tab arrives that fits me better. Service, however, was great!"

Vitamin K2 is BEST form for bone/heart!, April 9, 2007
By scottls

"To experience benefits for bone and vascular (heart!) health, 100 micrograms per day of supplemental Vitamin K2 (with fatty food is best) is suggested.
1. Vitamin K2 does NOT concentrate in liver, like K1 does (toxic...!) !
2. This is best value, as it also has 400mcg of vitamin D3 (D3 is !BEST! form & necessary!).
a. I also take another 400mcg of D3 with breakfast (recommended not to exceed 1000mcg of ANY D per day!- Reportedly, more D can cause hardening of arteries!)."
