SAM-E Depletes Dopamine

These studies are essentially saying that SAMe can damage the reward/movement system of the brain/induce parkinson’s/deplete dopamine, in rats.

I’m wondering what Dr. Mariano’s opinions are on this, is this something to be concerned about when supplementing with SAM-E for depression?
