## Description

l-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 can improve sleep and enhance mood, and may also be beneficial in reducing carbohydrate cravings. L-Tryptophan also supports immune functions because it is in the body&apos;s precursor to the kynurenines that regulate immunity. If needed, L-tryptophan converts to niacin in the body, which supports circulation, a healthy nervous system, the metabolism of food, and the production of hydrochloric acid for the digestive system A healthy body needs L-Tryptophan to improve sleep, enhance mood and also promote immune system efficiency.

*by D***A on Reviewed in the United States on February 23, 2016*

I got these pills because I have pretty low serotonin levels and did a little research to see what I can take to help. Apparently tryptophan is one of the chemicals that create serotonin. It's an essential amino acid, so I must not be getting enough from my meals (though that's a whole different topic). I've also been taking 5-HTP to help me as well. I can't be positive that this is helping me but it seems to be. I feel comfortable saying that I do feel better after taking it. It's not a huge change in my mentality but I do feel as if I'm a little happier. I have been using it alone and with other 5-htp products, and that overall pleasantness is apparent in both cases. I'm sure it's good for other things as well so I would recommend at least trying it once. I received this product at a discounted rate in exchange for my honest review. The discounted nature of this product in no way influences or otherwise affects this review.

*by J***. on Reviewed in the United States on February 1, 2016*

I had only ever heard of tryptophan as the main chemical in Thanksgiving turkey that makes you sleepy and since I have trouble sleeping I started researching what may work. Again it popped up and so I thought I would try it.I wanted to wait several days before writing my review because sometimes things work very well for a few days but then stop. This has NOT b een my experience with this product. I take it in the morning after breakfast (the directions say to take it after a full meal) and it has really made a difference for me. I am able to focus better and I'm waking up much less often at night. I am not a fan of large pills but these capsuls are small and very easy for me to swallow.No side effects or negatives to report so I am giving it five stars.I received this product at a discount in exchange for my honest and unbiased review.

*by A***R on Reviewed in the United States on February 1, 2016*

First off the dosage and quantity of these capsules is perfect so you don't have to end up buying a new bottle every few weeks, so I love that. I've noticed over the last couple weeks that my moodiness in the morning has definitely gone down. Sometimes when I wake up in the morning my head feels sort of cloudy, but after taking Tryptophan before bed, I've realized no matter what time I end up waking up, that cloudiness isn't as present. I have to say I do take this in conjunction with St. Johns Wort so I can't tell what percentage of the effect I'm feeling is related to either that or this supplement. Also I haven't really found a difference with how easy/quickly it is for me to fall asleep while taking this. Overall I think it's a great supplement to any diet, and the dosing/quantity of this product is superior to the competition. This product was provided at a discounted price in exchange for my honest review.
