The most damaging free radical to our bodies is the superoxide anion radical.  Approximately one percent of the oxygen we take in is converted to the superoxide anion free radical.  It is also believed to be the source of other reactive oxygen species such as hydroxyl radicals, peroxide and peroxynitrite.

This is particularly exciting, as consumption of freeze-dried  açaí, put into a liquid juice format for absorption in the body, could reduce the production of other free radicals, at the source, through its extraordinarily high superoxide scavenging ability.
