I’m fairly certain I accidentally gave myself K2 toxicity. I was taking two 100 mcg of MK-7 per day, once in the morning and once in the evening. I think this was working well for me. It thought it would be more convenient to buy the single 300 mcg capsules and take it once a day. You can probably guess where this is going…
So I started taking these higher dose capsules, but forgetting that they were 300 mcg each, I took them twice a day for a total of 600 mcg per day. Shortly after I was getting all sorts of strange symptoms.
Once I recognized what happened I stopped K. It was 2-3 months after when I began supplementing with vitamin E and NAC. I’ve been slowly but gradually feeling better.
Worth to mention that a large number of Japanes studies on vitamin K and osteoporosis (by Yoshihiro Sato and Jun Iwamoto) have been retracted due to "general misconduct, falsification/fabrication of data and results, false/forged authorship, concerns about results and findings, duplications of articles, and unreliable images, data, and findings" (see https://bps.stanford.edu/?page_id=9731)
They have (co-)produced massive amounts of studies, unfortunately now it is difficult to filter out the junk ones :(
