I have had very strong, strange effects from both MK-7 and MK-4, which I'm struggling to understand. I first tried a tiny dose of MK-7 and it made me feel great, but hyper and unable to sleep. Then I switched to a tiny (I mean, like 10 mcg) dose of MK-4, and it had the same positive effects, but less excitability.
Unfortunately, I noticed after taking it for about a week that my blood pressure (normally low-normal) was way up, I was having weird heart palpitations, and I was getting an increase in floaters and flashes in my eye. My heart checked out normal, but my eye turned out to have a retinal hole with fluid that had to be lasered, and I'm still worried about it. Though the doctors doubt it was anything I took, I totally suspect the MK for if not causing, then at least exacerbating the eye problem, because one of the positive effects I had previously noticed was a brightening of colors in addition to enhanced mood. I think it increased the pressure in my eye.
Anyway, it's sad I can't take K2 because it seemed to have a lot of good effects on my mood and energy, but it also had these scary, dangerous side effects that can't be ignored and which I'm still recovering from, even at tiny, tiny doses (also makes no sense because I've eaten plenty of cheese, pepperoni, grass fed butter, and even, years ago, natto, with no remarkable effects). I wish I could understand what was going on with me and K2. Any ideas?
Thanks so much.
