Product Description

Size: 50g

Best l-tryptophan products contain ajinomoto tryptopure. tryptophan is an essential amino acid readily converted by the body to the neurotransmitter serotonin. able to cross the blood-brain barrier, l-tryptophan is altered by enzymes to first form the intermediate amino acid 5-htp and then serotonin. it is also the metabolic precursor to melatonin and to the b vitamin niacin. supplementing the diet with pure l-tryptophan like tryptopure™, found in doctor’s best l-tryptophan products, can improve sleep and enhance mood, and may also be beneficial in reducing carbohydrate cravings.*

5.0 out of 5 stars Good product, April 7, 2011

Kay F Gibbs (Chapel Hill, NC United States) - See all my reviews
(REAL NAME)   
This review is from: Doctor's Best Best L-tryptophan Powder Featuring Tryptopure, 50-Grams (Health and Beauty)
I have used Doctor's Best Tryptophan from another company. I found it to be a very good product. I have also purchased tryptophan powder from other companies and they just were not the same, you can tell by the look of the powder, the taste and it's effectiveness. Doctor's Best was very effective at less than the recommended dose of 1 gram. I have used Ajinomoto's amino acid supplements from another company for over 10 years, trytophan was one of them. They are of the best quality I have used thus far and as I mentioned I have tried using other products but they just aren't the same quality. I am very picky after years of putting garbage into my body and damaging my liver making it almost necessary that I use amino acid supplements to promote the healing process.

I would recommend this product to my friends.

3.0 out of 5 stars Good product but not for everyone, December 9, 2011
Amazon Verified Purchase(What's this?)
This review is from: Doctor's Best Best L-tryptophan Powder Featuring Tryptopure, 50-Grams (Health and Beauty)
My doctor recommended tryptophan as a sleep aid. This is a good company and a great price--the comparable supplement in this amount sold with a prescription is $65!

Unfortunately, though this works great for thousands of people, it didn't work for me. It made me anxious, rather than relaxed. It happens that way sometimes. It's not the fault of the product.
