Vitamin K2 & Testosterone
What Is Vitamin K2
How Does It Impact Testosterone?
There have been no human trials in this area, but some rodent studies provide interesting results:
- Rats given 75mg of vitamin k2 per kg of bodyweight experienced nearly a doubling of their testosterone levels (6).
- In another study, vitamin K deficiency in rats significantly reduced their testosterone levels (7).
Vitamin K2 can provide tremendous benefits and should be included as a part of any healthy diet. It has also been shown to be associated with significantly higher testosterone levels in rats. Whether this effect carries on to affect us in the same way is hard to say.
