Catechol product image

Research indicates that individuals of differing blood groups can have extremely different responses to the same occasional stressors.

Type Os with mild to moderate stress benefit from the amino acid tyrosine (which can boost dopamine levels), and Arginine. Catechol also features the adaptogen Rhodiola rosea, which helps to modulate the effects of excess adrenaline.

This formula is more specific to types O and AB, but can be used by other blood types as well.
