This gene encodes a member of the aldo/keto reductase superfamily , which consists of more than 40 known enzymes and proteins. These enzymes catalyze the conversion of aldehydes and ketones to their corresponding alcohols by utilizing NADH and/or NADPH as cofactors. The enzymes display overlapping but distinct substrate specificity. This enzyme catalyzes the reduction of prostaglandin (PG) D2, PGH2 and phenanthrenequinone (PQ), and the oxidation of 9alpha,11beta-PGF2 to PGD2. It may play an important role in the pathogenesis of allergic diseases such as asthma, and may also have a role in controlling cell growth and/or differentiation. This gene shares high sequence identity with three other gene members and is clustered with those three genes at chromosome 10p15-p14. 
Hmmmm interesting. Funny you mention it because I was taking gaba not too long ago and it was in a mixture with some other stuff. Anyways, I think it was causing me to wake up kind of uncoordinated and feeling just kind of weird. Dissociative I guess you could say, which makes sense because it’s related to the NMDA receptors somehow I think. It supposedly “can’t” cross the blood brain barrier, at least this is repeated despite the fact that it can and does, it’s just an unreliable mechanism in which it does. Low levels of gaba were insinuated to absorb more in the brain also. I didn’t have this issue as if I took the full 750 mg I felt very strange consistently and none of the other supplements in the mixture would seem to do this.
Hi Roman, you might be able to answer this question for me since you seem to know a lot about dht. I’ve been on Propecia for over 14 years. It lost its effect the past three years now and I have been losing ground. Do you think topical Propecia might kick start the effectiveness again since it’s going directly to the scalp?
Sorry for the broccoli thing. It’s just you hear all these random treatments with naturals and it’s gotten to the point where I can only laugh at it. I do respect the fact you are looking into other avenues to fight hair loss which is more than many of us can do on here. Fingers crossed you solve another angle to hairloss.
