    Love this product

    Posted by iHerb Customer on Dec 25, 2017 | Verified Purchase

    It is the free form and works well for me. My labs came back with high tryptophan levels after taking for some time. This is the best, and I generally trust the brand. I check each support for the additives, this was is benign and works well.i take two to three at night. In the beginning took 3, three times a day to get my levels up. Calming for me. This is the only brand I trust right now, and it works, not gonna fix it. Worth the extra bucks..

    Thanks for your feedback!

    Take for relaxed sleep

    Posted by iHerb Customer on Mar 13, 2017 | Verified Purchase

    I have taken this L-Tryptophan now for two years. Dr. suggested it to help with RLS. Two caps taken at bedtime relaxes me and helps with sleep. I also take a slow release melatonin. My daughter also has now been taking same L Tryptophan for a year and will not go to bed without it, I recommend it.

    Thanks for your feedback!

    Excellent Quality

    I've looked at L-Tryptophan from different companies. This is the only one I've seen that's Kosher, pharmaceutical grade. It's the best bang for the buck. I take 3 of these with 3 Valerian tablets. It takes the edge off the stress when I want to relax even if I don't sleep. This product used to be available in a 100-count bottle. It was less expensive so I hope it's available again.

    Thanks for your feedback!

    Great Product

    After researching L-Tryptophan online I decided to order & have been using it since 11/09 in place of a prescription antidepressant. Believe I have noticed a positive difference, but had to adjust/increase dosage after 1 month. I would caution anyone to do research before taking this product to determine if it would be right for you. Bluebonnet has excellent products and iHerb has superb service!
