Some of the ingredients are actually just nutrients, the nutrients that you should get in food. If someone is going to be using some function a lot more than an evolutionary environment would have had them use that function, we supplement branch chain amino acids.

We can give plants or chemicals that modulate that process but that modulate the process in a much more holistic waythan say traditional psychopharmacologic approaches.
