Deflect O is a unique dietary supplement designed to block problematic food lectins known to interact with blood type O. Dietary lectins can bind to the blood type receptors in the gut and immune system and compromise the intestinal tract, inhibit healthy metabolism and disrupt the immune system.

One of Dr. D'Adamo's most popular and foundational formulas, Deflect® has a wide range of applications, including:

  • Assisting and maintaining healthy weight loss
  • Optimizing metabolism
  • Helping to develop a more balanced digestive system

When you eat a food containing a protein lectin that can react with your blood type O antigen, these lectins adhere to carbohydrate receptors throughout the intestines. While the reaction takes place in the gut, the harmful effects can reveal themselves throughout the body, in symptoms ranging from bloating, weight gain and lethargy.

Minimize inappropriate lectin activity by eating foods from the beneficial and neutral list for your type and supplement with Dr. D'Adamo's revolutionary Deflect formulas.

Since each blood type is susceptible to different lectins, Dr. D'Adamo has designed formulas specific to each blood type.

    I have a serious lectin intolerance. Deflect 0 is correct for my blood type and helps me to eat without getting all the usual horrible symptoms. Since I discovered it I am never without it. Thank you Dr. Adamo and all the team.
