I dont have much faith in natural stuff, but what about this kind of thing? Using these to try to lower PGD2 just with supplements. This web site sells supplements so maybe they have a bias on this, but you can buy these cheaper on amazon instead. Lowering PGD 2 might be possible naturally so maybe that does tie in with diets. Would lowering PGD2 even stop or alter male pattern baldness?
