I've been using 200 mg. Of Natpro per day for a few weeks now. Been reading lots from this site.. I take taurine, magnesium glycinate, tyrosine, vit. B sublingual, vit. B6 at bedtime, tryptophan, valerian root. I just got the vitamin d3 k2 (mk-4) in to begin taking. It says on the label there is 1mg. of the k2 and 2000 iu of vitamin d3. I've read that this amount of vitamin d3 is too low...but unsure how much of the vitamin k2 is too much..I've also read that vitamin k2 is used to coagulate blood. I don't want to take too much of the vitamin k2 (mk-4) to get enough vitamin d3. I would need to take 5 of the chewable tablets per day to equal 10,000 ius of d3...that would be 5 mgs. Per day of the k2. I don't take blood thinners, except a dose of 400 mg. Of ibuprofen at bedtime. I am 56 and I do have concerns about thickening or sticky platelets could cause a heart related incident. I do not take any rx meds at all.
Look forward to your reply..and reading experiences of others.
