"This stuff works folks. I've tried just about every alternative medicine supplement on the market for insomnia and nothing comes close to being as effective and, most importantly, consistent. I tried 5-HTP but it lost its effects after about 2 months. Plus Doctor's Best uses TryptoPure L-Tryptophan which is the same tryptophan used in hospitals. Just Google TryptoPure and research for yourself. Tryptophan can also be taken during the day for depression & anxiety. It gives me a sense of tranquility during the day and induces sleep at night. Remember that L-tryptophan is an ESSENTIAL amino acid which means the body CAN NOT manufacture it's own so it MUST be obtained through the diet or in supplemental form."

Delighted L-Tryptophan is back!,
March 22, 2008
By DaisyChainfrom California
"I have been using 5HTP as a mood enhancer and was delighted to discover that the government has lifted restrictions on over-the-counter L-Tryptophan. Doctor's Best is a superior brand. I use this product before bedtime to help me sleep and during the day when I feel highly stressed. If I waken during the night, I take it again to help me get back to sleep. It always works and I am immensely grateful for the benefits. Last week I urged my sister to take it since she was in a lot of anxiety over the memorial service we planned for our father. I could tell an immediate improvement in her behavior. I highly recommend it."

"doctor's best are excellent, quality formulations and their tryptophan is a great example of their standards. Tryptophan calms the nervous system and is useful for those under stress. I ama radionic practitioner, and can therefore test the quality of indidvidual products, and believe me, all brands are NOT the same."
