do any of the ingredients come from China?

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.

How long until I start seeing results?

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.

What does this product do for your body?

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

is the veggie cap made from hyrpomellose?

You should probably contact Superior Labs in Park City, Utah for this information.
