Hi Linkadge,

I responded to your original post on increasing MAO activity with some thoughts on copper supplementation. Here's a link to my response:

http://www.dr-bob.org/babble/alter/20061013/msgs/702120.html

Another type of supplement that might increase MAO activity would be something with anti-estrogenic properties. Holschneider et al. (1998) found that estrogen administration significantly decreased MAO-A activity in the hypothalamus (-28%) and amygdala (-21%) of female rats. The researchers also detected significant reductions in MAO-B activity in the liver (-30%), kidney (-22%), and uterus (-57%) of the rats. Another group of researchers (Gundlah et al., 2002) found that estrogen treatment reduced the optical density of MAO-A mRNA in the dorsal raphe nucleus and in the hypothalamic paraventricular nucleus, lateral hypothalamus, and ventromedial nucleus of spayed rhesus monkeys.

So, if you're willing to try a supplement with anti-estrogenic properties, then that should theoretically raise MAO activity (assuming that the supplement doesn't also reduce MAO activity by some other mechanism). And that's assuming that such a supplement exists. I'm not sure if there are any commercially available supplements that reduce estrogen activity, but then again, I haven't looked.

Hope this helps a little.
