There are many types of depression & so many routes to curing it.
If you're serious, you need to read a book on the subject such as Julia Ross's "The Mood Cure". She lists lots of supps - chiefly amino acids & NT precursors such as 5HTP, GABA & tyrosine.
But if your thyroid is low, or you have a Mg or Fe deficiency, you'll be depressed because of that - & will need to supplement accordingly. If you suspect these, do tests.
