I have have been using this product for approx. 1 1/2 yrs. I have tried other brands of L-Tryptophan and I think this is the best. You also offer it at the best price around. Thank you.

My father, a Chiropractor, always had us use L-tryptophan during high stress events,ie. weddings, etc. It made such a huge difference-with no side affects. Then it was banned...... My health food store tells me it's still banned and they don't carry any! I was delighted to find several brands to choose from at iherb and Source Naturals has been my choice with many suppliments in the past.
