Q. How long before they can expect to see a "calming" effect with cd Stress?

Answered By

A. Both supplementation studies (L-tryptophan and hydrolyzed casein) were conducted over 8 weeks, so I would conclude that it may take up to 8 weeks or longer before an effect is noted.

I would also add results may vary between individual patients because not every patient in either study was found to have a beneficial or change from baseline.
