Superior LabsL-Tryptophan 500 mg Capsules, Pure Non-GMO Amino Acid, High Absorption, Natural Sleep Aid & Mood Booster, Stress & Anxiety Relief, Premenstrual Syndrome (PMS) Support, 120 Veg Caps

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

As advertised

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

This works so much better for me than melatonin but it's not time released so I take a time release melatonin too. Might wake up once but then able to go back to much needed sleep. It happens with age!

I have been on these going on 3 weeks about and seem to be working, I take one at night with a glass of calm magnesium product and in the morning I take 1 vitamin B complex by Naturelo. I really see a big difference from before and seems to be working well for me since I do have high sensitivity to certain products.
