Since it sounds like domestic L-Tryptophan (5HTP precursor) has been quietly allowed to be sold in the US, I wanted to examine the topic of 5HTP vs L-Tryptophan. Some books on 5HTP mention that L-Tryptophan is a better alternative to 5HTP (better absorption though BBB etc)... Has anybody heard more on this theory? I would imagine that 5HTP is better cause it's closer to serotonin in the process...
