I strongly believe a supplements with right proportions of aminoacids can have a positive effect in everyway in any ailment. If digestion is weak (low stomach acids, blocked bile flow, overstimulation of pancreatic juices, wrong combination of foods, overeating) protein breakdown and aminoacid absorption will be reduced (along with EFAs and important nutrients). Aminoacids are raw materials for every enzyme, neurotransmitters, hormones and important chemicals that are required for a balanced system. Excess daily stress and overstimulation of adrenals can exaust these important components so the aminoacid demand will increase.
A good balanced free form amino acid supplement can slowly correct any imbalances, but one should also address the root cause of this, which is weak digestion and stress (bowel cleanse, and Liver Flushes can do wonders)
