== Protection from radiation Comment == 

 Reading the discussions, I am not the first to notice and am in no way appeased by statements such as, "I admit the article needs some work." 

 Long before I reached this subheading I was fairly certain I was reading an advertisement for snake oil.  A bit of clarification would be helpful here.  For instance: Are the properties which limit damage to the human body from radiation related to the properties by which Melatonin reduces the effect of voodoo curses?  This is important to the few who may have been born not only with a functioning brain but also armed with skepticism and not afraid to use it. 

 Not worried about Fukushima?  Then try it as a recreational drug like Marijuana, or maybe even LSD!  No?  Then how about using it to kick that cocaine habit!  Sex life got you down?  Melatonin is the drug supplement for you!  Also good for fire ant infestation, global warming and acne!   

 I'm a fraction of a tick away from lobbying for deletion. 

    

 :It may be snake oil as it stands, but there could be something to it. Melatonin is an antioxidant, as the article covers (I think); and absence of melatonin (as in shift work disorder) is linked to cancers...   16:12 5 May 2011 (GMT) 

 ::Something that is pretty much as bad as a snake oil salesman is someone who claims something is snake oil based on preconceptions rather than the scientific evidence. It is clear from the scientific evidence that melatonin has significant antioxidant properties, and various physiological effects as a result, including (obviously?) reducing the effect of various toxins (some of which are carcinogenic) and radiation. But presumably the fact that this statement includes the words "antioxidant" and suggests medically significant benefits makes it automatically "snake-oil" to someone who then has the arrogance to suggest there should be no article on melatonin in wikipedia (perhaps he believes the chemical should be deleted from metabolic pathways as well? ) )
