Superior Labs – Pure L-Tryptophan – 500mg, 120 Vegetable Capsules – Non-GMO Dietary Supplement for Restful Sleep & Relaxation – Supports Feelings of Well Being and Healthy Circulation Circulation

I have been taking these one per night for several weeks. I can tell you this is the absolute best sleep I have gotten since 1990. I was on shift work for many years and have been retired for 7 years now. I think shift work messed my sleep up especially with the job being so stressful at times. I cannot say enough how much good this Tryptophan has done for me.

It helps me sleep but not used alone. I use Ornithine from Dr. Clark Store to help. I respect Superior Labs for not putting magnesium stearate and other harmful fillers that I am aware of. I didn't have any side effects or upset stomach. The effectiveness wasn't as good alone as I expected, but I am only one case. I will keep my trust in Superior Labs until I see something that is unnecessary filled in and dangerous additive. So far I like them.

Works GREAT for relaxation

No bad effects so far.

Give me another couple of weeks to try this and then learn what I like and if it works for me.

No nasty fillers or flow agents. I will buy again for sure

It works but I wake up groggy and foggy brained. 500mg per capsule is too much.I can’t imagine taking the recommended 1,000!!More isn’t better!! If you’re sensitive try starting with 200mg instead.
