I’ve been working on my D levels, and ended up with super high levels. In trying to reverse some autoimmune issues I was taking about 50,000 a day. I started getting hot flashes and absent periods. In researching I realized I needed to add K2 and that stopped the hot flashes. A side effect of the k2 has been a huge increase in libido. Seeing that K2 can raise testosterone I thought I would post this to see if anyone else has tried. Unfortunately it hasn’t helped my fatigue. But it has helped my super sensitive and bleeding gums.
Make sure your D is optimal if you try this. I believe it to be the combo that has increased libido
