Yes, that happened to me! I was taking MK-4. It is documented that MK-4 can raise levels of some lipids- Lp(a). My cardiologist had me stop taking and retest and three months later my test was normal. I’ve had Mk-7 cause flutters, but may try very low dose to see if that works. Some evidence that MK-7 may improve some lipids as well as help direct calcium to bones. Google for pumped/nih articles. My nutritionist says I may just not be able to take Vit. K. Good luck!
