5 Customer Reviews Write a Review

The original shield against lectins. Designed to block problematic food lectins known to negatively impact Blood Type ABs.

Select your blood type: O A B AB

Sometimes, Avoids are simply unavoidable.

Meet Deflect AB, your first line of defense against lectins in Avoid foods. A class of proteins that bind to the different antigens in each blood type, lectins can harm immune and digestive function. This causes a variety of health problems including intestinal and bowel irritation, bloating, weight gain and lethargy. Shielding your biology from these dangerous molecules is important.

An exclusive blend of larch arabinogalactan, chondroitin and pineapple, Deflect AB is crafted for optimal absorption by Blood Type ABs. Dr. Peter D'Adamo's uniquely formula provides specific blocking sugars that attach to receptors on lectins, preventing them from weakening immune and digestive health.

  • Knocks out specific Type AB dietary lectins before they hinder digestion
  • Boosts metabolism
  • Reinforces immune defenses

Our lectin-fighting team includes:

Larch Arabinogalactan
Binds dietary lectins and reduces bacterial adherence of detrimental species such as E. coli. Larch arabinogalactan is also an excellent source of dietary fiber and has been shown to increase the production of short-chain fatty acids (SCFA), principally butyrate.

Becomes smaller peptides upon breakdown in the stomach, resembling the Blood Type A antigen. These molecules can then bind to A-like lectins and prevent attachment in the intestinal tract.

Contains a naturally occurring form of mannose, providing the anti-adhesive benefits of mannose along with the anti-inflammatory benefits of bromelain found in pineapple. Pineapple is also a Beneficial for Blood Type AB.

    I've been using Deflecr AB for a few years and since I started, my terrible stomach and abdominal pains have disappeared. I should mention, I use Intrinsa and ARA 6 also. This combination is perfect.

    I have been on Dr. D'Adamo's ab diet plan for several years, but after losing 90 lbs and regaining a healthy feel, reached a year long plateau with no further weight loss. I purchased two bottles of Deflect AB and have been taking two twice a day for about a week. Two pounds have vanished. I conclude that the product may be the answer I have been seeking. Will write again after I have been taking the product for a longer period.
