Deflect A is a unique dietary supplement designed to block problematic food lectins known to interact with blood type A. 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 A 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 feel better eating something I shouldn't occasionally when I know I can take a couple of Deflect A for my blood type. It's nice to know Deflect gets rid of lectins that are no good for your body.

    I use Deflect fairly regularly when eating something that could harm me, also been using the capsules mealtimes to help with allergies which I seem to suffer with as I age!

    I take the capsules with a meal if I know I will be eating something not good for my blood type, as far as I'm concerned they work.

    I stick more or less to the foods for my blood group. But when I know I will be eating something not suitable I take Deflect with the meal.

    As a follower of the blood group diet, I find these products an essential part of my diet. I have used many of my blood group supplements and find them helpful.
