## Questions & Answers

**Q: do any of the ingredients come from China?**
A: I can't believe how many people are outraged by supplements coming from China. 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.
