Seems to have pure ingredients. No carageenan or magnesium stearate. Read your labels
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.

Best Sleep I have gotten in Years!!!
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.

The road to health in a bottle.
Give me another couple of weeks to try this and then learn what I like and if it works for me.

Superior Labs – Pure L-Tryptophan – 500mg
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!
