Melatonin
My Medical Qigong teacher and Traditional Chinese Medicine doc says the best melatonin is what comes from the body itself, that exogenous supplementation isn't as good. We see greying hair when there isn't enough.
It turns out that there are two special melatonin receptors in the cerebellum.
I am taking 1-2 orally soluble tabs a night of melatonin. My sleep hasn't been as good since the start of December but the ketogenic diet is known to interfere with sleep. I try to take it in stride and get as much as possible besides that, even if it is in batches of 3-4 hours.
Preventing and Counteracting Adverse Effects of Radiotherapy
Melatonin reduces oxidative damage from the production of free radicals (Reiter RJ 2004). Several studies indicate that melatonin functions as a radioprotector (Karbownik M et al. 2000), reducing the toxic effects of radiation on mammalian cells (Vijayalaxmi et al. 2004)
