Description:
Catechol is ABO friendly. An increasing amount of evidence indicates that individuals of differing blood groups have extremely different responses to the same stressor. Equally surprising, the genetics of blood group also appear to alter susceptibility to developing certain neuro-psychiatric disorders.

Type O's with mild to moderate depression benefit from the amino acid tyrosine (which can boost dopamine levels), and arginine (which is used to recycle nitrous oxide in the nervous system). This product is more specific to type O, but can be used by other types as well.
