Take with lots of water
Works great but swallow it all the way down with lots of water. I had the foulest burp of my life when it got stuck halfway down. I would still buy this product again because it works to get me to fall and stay asleep. Just want to forewarn even though you'll figure it out anyway.

Effective and good value
Great price. Started working in only three days. Helps to get you ready to go to bed. Good price. No unpleasant odor or burping. Easy to swallow. Would recommend.

Says it's pure, but the smell says otherwise
While it does still seem to work, I'm a little put off by the smell. The smell is likely from indole derivatives, a substance produced in the degradation of tryptophan. I rather wonder to what level the contamination is present. If it is in fact indole derivatives, and if they are in sufficient quantities, they will actually work against the l-tryptophan in the body. Oh, and the smell? Unfresh kitty litter. Indole is related to scatole. Scatole is a molecule responsible for the smell of feces. It's not quite that bad, though.

Capsules are only 280 mg. This is not revealed in the product description.
This company is selling 280 mg capsules. The average dose is 2000 mg from regular users. You would need to consume SEVEN of these if you are used to taking 2000 mg at night. NOBODY sells l tryptophan in less than 500 mg capsules. Waste of money. This bottle won't last two weeks. Pathetic.

Best product!
I have been using L-Tryptophan for a long time. This one is by far the best one among all that I have used.
