And again, I find it particularly interesting because there's a logical biochemical pathway to support the finding that it improves mood and can offset the effects of major depression in some cases, or can improve the effects of antidepressant medication in many cases. When I see mechanism and I see effectiveness, and the mechanism and the effectiveness map to a lot of the same mechanisms that are involved in prescription drugs, that gives me great reassurance that this isn't just some sort of mysterious pathway or mysterious compound by which a creatine might be working.
