9 Customer Reviews Write a Review

Blend of herbs, nutrients and vitamins to combat fatigue and support a healthy response to stress in Blood Types O and AB.


Blend of herbs, nutrients and vitamins to combat fatigue and support a healthy response to stress in Blood Types O and AB.

In today's modern world, occasional stress can be problematic. This "slow burn" can sometimes disrupt our ability to sleep, digest our meals properly, and maintain a healthy immune system. While occasional stress is a body's method of reacting to a challenge it can also disrupt the body's natural reaction to any stimuli that disturbs its equilibrium resulting in a 'fight-or-flight response.'

Research indicates that individuals of different ABO blood types can have extremely different responses to occasional stress. As a result, Dr. Peter D'Adamo, author of Eat Right 4 Your Type, developed Catechol personalized nutritional supplement to help the body regulate nutritional stress support, while helping to promote a natural state of calm in individuals with Blood Types O and AB.

This 100% vegetarian product has a unique 'three-layer design':

  • Layer 1: A base of B-vitamins (including methylcobalamin, the active form of vitamin B12) and the mineral selenium
  • Layer 2: A layer of amino acids, including tyrosine, methionine and trimethylglycine; all known to be critical nutritional factors that can be depleted due to occasional stress or poor diet.
  • Layer 3: A blend of two well-researched botanicals that have been studied for their effects on occasional stress: Magnolia and Rhodiola

60 vegetarian capsules
Suggested Use: Two (2) capsules 1-3 times daily. Best taken away from food.

    I chose Cathechol to assist me with the fogginess experienced from my thyroid condition. Cathechol work! There is increased clarity of thought; my assurance levels is up and it feels good. Considering purchase of Tranquility as the complement to Cathecol. Thank you, Dr. D'Adamo (staff) for excellent and blood appropriate products!

    I think Catechol helps me control stress levels soooo much that I considerate one of my foundational supplements. It seems I need 2-4 almost every day so I always have an extra bottle on hand! I'm a BTO nonnie.

    I take one to two per day and find I have to take these to keep my mood balanced during nenapause. Catechol helps so much

  • Great mood enhancer

    Posted by Anonymous on Jun 21st, 2015

    When I take Catechol my moods are so much better. Being a 50 year old woman, I found my moods would really swing when I didn't take Catachol twice a day. Depression and anger would get the best of me. Catechol seems to take that away. Thank goodness!!

  • wouldn't be without it!

    My life has a lot of unavoidable stress in it. Catechol helps me get through my day. A great product that works gently but is very effective at taking the edge off anxiety and stress. Highly recommended.
