Tested as: Not recoverable from the review. Only five trials were pooled and the review reports no single zinc salt, dose or duration; in most of them zinc was given as an add-on to an antidepressant drug rather than alone.
Who was studied: Children, teens and adults. The gain came from people already on drugs for depression.
We found 1 study on this. We have not finished reading them yet, so we are not ready to say either way.
