GABA for Anxiety and Depression

GABA or Gamma Amino Butyric Acid is an inhibitory neurotransmitter which means that it blocks nerve impulses. It tells the nearby cells not to fire or send nerve signals.  Without GABA, the nerve cells fire too often which results into a number of anxiety disorders.  Some related results of low GABA activity are panic attacks, addiction, headaches, seizure disorders, Parkinson’s syndrome and cognitive impairment.  Some scientist says that GABA cannot penetrate into the brain. To increase the chances of GABA penetrating the brain, larger oral doses in the gram range could be used. Another strategy is to use Picamilon, it is essentially GABA bounded to Niacin which is able to cross the blood brain barrier.



“Research found that the mean GABA level in the brain of the depressed patients was less than half of that found in the healthy controls” (Sanacora, Gerard, et al. Archives of General Psychiatry, Vol. 56, November 1999, pp. 1043-47)
