I'd like to try L-tryptophan or 5-HTP. Anyone have any recommended brands or dosage instructions for these?

I take 100mg of 5-HTP every now and then, seems to help with my sleep.

Out of the products at iherb.com, this (http://www.iherb.com/Now-Foods-L-Tryptophan-500-mg-120-Vcaps/13859?at=0) is the tryptophan I chose. This (http://www.iherb.com/Healthy-Origins-Natural-5-HTP-100-mg-120-Capsules/14472?at=0) is the 5-HTP I might have bought.

Those tryptophan caps do not contain rice flour, but the 5-HTP caps do. I couldn't find any reasonably priced 5-HTP caps that didn't contain rice flour. That's one reason I chose tryptophan over 5-HTP.

The other reason is the chain of conversion: the body can convert tryptophan to 5-HTP, which it can conver to serotonin and melatonin. I prefer letting it decide how much of each it wants to make from a lower level than a higher level.
