The Negative Feedback Loop on Melatonin

Melatonin is more than a hormone. It flexes, it's unique. In fact, I would not even put it classically in the hormone bucket. So it's not going to play like the other hormones. And again, I would never discourage people eating these plant foods that are enriched in a number of different phytonutrients,. But I wouldn't be thinking about them for melatonin. All right, last question. If I take melatonin, I won't make my own. Is that true?
