I've done a fair bit of research about Vitamin K2 and this is the best buy I could find in the market. No matter which vitamin K2 product you decide to use, make sure it is Vitamin K2 as MenaQ7. That is the only clinically validated vitamin K2 on the market. I would prefer a stronger dose (180 instead of 100 mcg) of Vitamin K2 (MK-7)in a single pill, but until that arrives I will use this product to maintain a healthy heart and strong bones. (Below is an update half a year later after my review above) One very positive side effect I did not expect! - I am working a lot in front of a computer and have had issues with Repetitive Stress Injury (RSI) for many years. A month or so after I started to take MenaQ7 the pain disappeared and has not come back!

Hi I think I got heart palpitations and difficulty breathing from this product. When I upped the dose the palpitation got worse. I am switching to mk4, in the hope there won't be such side effects.
