Product Overview

Description

  • Dietary Supplement
  • Mood, Relaxation, Sleep
  • Non-GMO Validated

The essential amino acid L-tryptophan helps support relaxation, restful sleep, and feeling better. It plays a part in the synthesis of both melatonin and serotonin, hormones involved with mood and stress response. L-Tryptophan also supports immune functions because it is the body'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. Source Naturals L-Tryptophan is extremely pure and is regularly tested to ensure the highest standards of quality.

Suggested Use

1 tablet three times daily, between meals and preferably with fruit juice. To support restful sleep, take 3 tablets before bed.

Other Ingredients

Dibasic calcium phosphate, stearic acid, modified cellulose gum, and silica .

Seems to be helping

Posted by iHerb Customer on Oct 19, 2017 | Verified Purchase

After coming of medication, I had my first panic attack (in many years) after about 12 weeks, the L-Tryptophan give me the same headache as I got when I first went on the medication but hopefully without the other medication side effects. I hope it keeps working, I need to be very careful with my diet, anyone wanting to take tryptophan needs to do their own research about how it reaches the brain, do not rely on Doctors who are not up to date, science is constantly changing as more and better research is being undertaken.

Thanks for your feedback!

Not As Affective as the capsules

Posted by iHerb Customer on Aug 29, 2017 | Verified Purchase

I recommend the capsules over this pill form. I didn't realize I bought the wrong one. It works somewhat...but not near as affective. I'm going to stick it out with these, because I paid for them...can't wait to go back to the capsules!

Thanks for your feedback!

Great for anxiety and depression!

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

I've been taking 2 of these a night for almost a year and swear by them for the relief of anxiety and depression. They don't make me feel drowsy or hyperactive, they just gently make me feel better. It can take a week or two for them to take full effect. I haven't noticed any side effects and don't see myself ever stopping them unless I have to. I take them along with 2 x L-Theanine, also from source naturals.

Thanks for your feedback!

Meh

Posted by iHerb Customer on Jul 16, 2017 | Verified Purchase

I didn't find this form of Tryptophan effective. It was better when I crushed the pills and dissolved under my tongue (which was pretty bitter!!), but it still wasn't very effective at decreasing sugar cravings or regulating sleep. I was very disappointed because I usually have great success with Source Naturals.

Thanks for your feedback!
