17-BETA-HYDROXYSTEROID-OXIDOREDUCTASE

[unixon_31 at hotmail.com]

Does any one know of any existing vitamins , minerals etc... that can
inhibit 17-BETA-HYDROXYSTEROID-OXIDOREDUCTASE 's ability to turn
androstenedione into testosterone ?
Zinc , saw palmetto ,vitamin b 6 are known to have inhibitory effect on
testosterone's conversion to dihytestosterone by preventing 5 alpha
reductase from doing its job.
 
Thanks
