A website selling Himalayan Salt advertises:

As a trace mineral, arsenic is a necessary part of healthy blood. Small amounts of arsenic are essential to life.

Is this claim true?

  • I've heard this claim before from a university Health educator. (Note: She was a little on the paranoid side, and not an expert on the topic.) – called2voyage May 12 '16 at 18:59
  • Dartmouth Toxic Metals makes the claim that it is beneficial in some birds and mammals, with humans being controversial, but sadly no additional links to proper studies (links tend to focus on acute arsenic poisoning). – Jimmy M. May 12 '16 at 19:21
  • Given that the WHO recommend 10 μg/litre (or 10 billion parts per litre) as a limit for Arsenic in groundwater, you probably don't want to supplement it into your diet... – HorusKol May 13 '16 at 5:04
  • Not sure how this question could be answered if this is not true. You could say that there are no known processes in the body that use As, I suppose.(Also : "On the other hand, arsenic the chemical formulated in a lab is highly toxic and even deadly in large doses." gah) – gilleain May 13 '16 at 7:47
  • I don't know about it being necessary for health or essential to life. I do know that it generally is prevalent (in trace amounts, at least) in the human body. – voices May 13 '16 at 12:32
