I can only surmise the reason I felt the POWERFUL effects of K2 Mk4 the first day for my gums, teeth, sinuses, and incredible Libido was that I had been taking an aspirin a day as my brilliant heart Doctors suggested! (sar off)
An aspirin a day severely reduces vitamin K absorption!
Also I had been on Warfarin for a over a year to dissolve the thrombosis clot that the medicated stent caused!
The main thing, that men want to leave women with, when they part ways albeit temporary, is a SMILE!
Here is more eye opening data:
As the data goes to show there was - despite the usual diurnal ups-and-downs a clear trend towards increased serum testosterone levels in the MK-4 group - on average, +56% more testosterone from weeks 1-5 in the MK4 group. And a whopping +70% at the end of the study period. An even greater increase of +88% was seen in the tissue concentration of testosterone within the testes. The latter went hand in hand with a profound enrichment in vitamin K2 content in the reproductive organs, as well as in the livers of the MK4-supplemented animals (no, I did not make a mistake, there really was almost no MK4 in the livers of unsupplemented animals, cf. figure 2).
