Good product.

Used this for two months with VIT D3 10000iu daily. My OH-25 is 72 ng/l now and stable. Vit K I read in several studies is a must with Vid D to reduce the risk of deposit of calcium in artheries. Good product at the best price available on iherb i believe.

Be cautious - racing pulse in night

Posted by Reviewer2437416 From India on Aug 13, 2011

Purchased at iHerb

i have tried 3 times and every time with single capsule i have woken up in night with rapid breathing with racing pulse. The last time i tried i split the capsule and took just half of the ingredients but ended with same symptoms. reading on the net found that Vitamin K2 can cause heart arrhythmia. All i can say i am otherwise a very health individual and would advocate caution while having Vitamin K2 supplements

My doctor recommended I take this product in conjunction with Vit D and calcium. I have been taking it for over a year, and I have had no problems with it at all. IHerb's price and shipping are the best I have found for this product.

Exactly what I needed

Purchased at iHerb

This formulation of Vitamin K2 is exactly what I needed to integrate with my other supplements of Vitamin D and Calcium and the rest of my heart healthy diet. I am in Oklahoma City and there are no local distributors for this or any other Vitamin K2 supplents (as far as I can find), so I am thrilled that iHerb carries this item. Thanks!

I use this 3x/week in conjunction with Calcium, magnesium, D3, Ortho Molecular Strontium, Selenium and Life Extension Only Trace Minerals to rebuild bones. I was able to reverse bone lose using these products in a year.
