If you look at melatonin, it's a primary protector from stress. And, so, if we were to compare it to something, I would like to compare it to the electromagnetic field around the earth. That's an internal-produced field that extends outside of the Earth, and it's protecting us from the ultraviolet rays that would normally kill life on the planet.

One of the interesting things I found in the literature with melatonin supplementation for a lot of gut diseases is that they actually found that there's a suppression of the bad bacteria and a support to the good bacteria.

Melatonin has actually been shown to really strengthen the autonomic nervous system—in particular, the parasympathetic nervous system ... I've actually seen some dramatic improvements with heart rate variability with both myself and also some of my patients.
