Vitamin D: this is a deep subject, a large number of functional medicine doctors and bio-hackers highly recommend taking 1500 - 2000IU's of vitamin D a day for a
lot of reasons, but for the scope of this subject the vitamin D helps your body produce
less of a globulin that binds
testosterone, helping your body utilize T better (make sure to get fifteen minutes of unfiltered sun a day to help your body activate the vitamin D, to get more T, to help give her more D).
