I wonder if any of these same people take pharmaceutical drugs, EVER? 90% of those are made in China. Just a thought. **Q: How long until I start seeing results?** A: I took two capsules before bed, and it took about a week for me to start feeling the benefits from this medication. As I said in my review I did not gain much as far as sleep, but it did help with depression. **Q: What does this product do for your body?** A: L-Tryptophan is an amino acid that converts serotonin in the body, this supports multiple brain functions and helps to maintain serotonin levels to promote relaxation and produce a better night’s sleep. Best Regards, Cliff **Q: is the veggie cap made from hyrpomellose?** A: You should probably contact Superior Labs in Park City, Utah for this information. ## Customer Reviews ### ⭐⭐⭐⭐⭐ More effective than others *by E***Z on December 12, 2025* Compared to a previous one I've used, this L-Tryptophan seems more effective.
