I started taking the same D3/K2 MK7 capsules again 5 months ago. At some point, the hectic work routine was over and incidentally I also quit using the supplements, after which I stopped having chest pains/cardiovascular problems. At that time I was working hard for long hours to finish a PhD so I thought it had to be related to working too much. The chest pains were so intense that I thought I was gonna have heart attack. After 1 month of usage, I started having severe chest pains, increased heart rate and high blood pressure. But I found a lot of useful discussions about K2 MK4 on this forum, so I'd like to share my story and help those who might have similar issues.Ī few years ago I started supplementing daily with D3/K2 (MK7) (100 ug / 75 ug) capsules along with some other supplements.

I'm 29 year old and don't have osteoporosis.
