Headache Relief: Jarrow Formulas MK-7 Softgel 90 mcg

Maybe I got a bad batch, or maybe this is bad for some …

I began taking this a few days ago. Last night my chest started to feel "heavy" and tonight as well. I do have slightly high blood pressure and very rarely have heart palpitations......haven't had them for months tho, until I started taking this vitamin. I'm going to stop taking it now and send it back for a refund. Maybe I got a bad batch, or maybe this is bad for some people. It is always a good idea to do alot of research on any supplement before taking it and talk to your doctor first. Now going through all these reviews I'm seeing alot of other people have also had problems with high blood pressure and heart paliptations while taking this too. I wish I hadn't taken it and I hope it wears off soon because I feel really uncomfortable right now........which I don't normally. I've also had a Headache all day today, which I also don't normally have either. Very concerning

I took the supplement for 12 days before doing a bit more research due to stagnant blood in my tomato-red toes, and unusual Headache. What I found is that the amount of vitamin K2 necessary for proper coagulation is far less than the amount required for bone-building/preservation, and also that this product thickens blood. I did take note that the recommended dosage was just one small softgel, and I see the reason for that being that it is very potent. It exacerbated my own problems, and I would encourage anyone using or considering this product to give thought to the fact that it is a blood thickener. Edited to add 11/27/12 - I just came across this excerpt from Yahoo News, and thought it was relevant to the discussion. - Leafy green vegetables. Kale, spinach, Brussels sprouts, and cabbage can make medication that combats blood clots less effective. That's because these foods are high in vitamin K, a crucial nutrient for clot formation, while the goal of anticoagulant therapy is to slow down production of vitamin K to reduce clot risk. In effect, these foods counteract the drug's desired effect. Drugs these foods can interact with: Warfarin (Coumadin). If you take this drug, it's not necessary to avoid leafy greens--instead doctors advise eating a consistent amount week to week, so your dose of warfarin can be calibrated accordingly. [...
