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.

Taken along with vit. B6 at bedtime helps to stay asleep all night. I cut the 500mg. tab in half, with 25mg. of B6.

I use Tryptophan on nights that sleep is elusive, and they work well. It is also a precursor to serotonin.
