It didn't work the same for my wife though, she took it and couldn't sleep

L-tryptophan is naturally found in animal and plant proteins

Works good and does not contain any filler

I take 5 grams (1) teaspoon and it works! best products on the market for supplements

Good for sleeping My husband takes this along with several other amino acids (mainly ornithine, lysine & arginine) & he has been packing on the muscle since he's been taking it

For one I'm getting actual product without all the binders
