SerotoninFX, Supp?


It's called SerotoninFX it says Pharmaceutical grade L-tryptophan (not 5-htp) and it can be used for enhanced sleep, mood control, recovery from exercise and controlling carbohydrate intake.

I saw this just browsing through a few things and it looks interesting but not sure what to make of the product and its claims. I'm only curious about it because I have anxiety and also typically have a tough time falling asleep not matter how much I work out.

Anyone use it? or have more info or thoughts?



It's strange, but as silly as the ban on supplemental tryptophan may be, you have to wonder about a company that will defy the law outright.

This kind of illegal activity is just sketchy to me.


The FDA lifted the ban on tryptophan in 1994.



Thanks for the info Bri!

NOW I wonder why TRP is not included in any amino acid supplements... we wouldn't even use it for most studies in the lab.


I did not know this was available either, just looked it up and sure enough it's all over the place.
