Many experts believe it's the caffeine that's providing the natural anti-depressant benefit and that almost any source of the stimulant could provide similar results. 2 - 4 cups of coffee is equal to around 400 mg of caffeine. Interestingly, drinking more than 4 cups of coffee per day doesn't appear to lower suicide risks.
Caffeine's powerful effects on human brain neurochemistry are well known. It acts as a "mimic" of an important tiredness-regulating chemical called adenosine and strongly affects levels of the neuro-stimulating chemicals dopamine and glutamate. The overall effect is a big boost in mental energy/stimulation and, it appears, a lessening of depression.
The findings aren't conclusive but at least it gives us another reason to spend all that money on Starbucks!
