Deflect - Lectin Blocker (Blood Type B)

9 Customer Reviews Write a Review

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

Select your blood type: O A B AB

Sometimes, Avoids are simply unavoidable.

Meet Deflect B, 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 glucosamine, pectin and larch arabinogalactan, Deflect B is crafted for optimal absorption by Blood Type Bs. Dr. Peter D'Adamo's uniquely designed formula provides specific blocking sugars that attach to receptors on lectins, preventing them from weakening immune and digestive health.

  • Knocks out specific Type B 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.

N-Acetyl D-Glucosamine (NAG)
Acts like a magnet for lectins in foods such as wheat and other grains. When lectins bind to the NAG on your cells, they impair their functioning and promote inflammation. The NAG in Deflect serves as a distractor, picking up stray lectins without interrupting your metabolism.

Works by inhibiting carbohydrate-binding lectins. Inhibiting this binding prevents the activation of immune cells in the gut. Pectin is a common component of several fruits and a soluble fiber used to improve digestive health and stave off gastrointestinal discomfort.

While it can't magically turn Avoids into Beneficials, Deflect B may assist in healthy weight loss and the repair of pre-existing lectin damage. With the help of our formula, you can support a balanced digestive system.

    Since I've learned about lectin complications, I've been taking Deflect. And why not go with one that is specifically for my blood type! It works for me.

  • Great Research on Product

    Posted by Noreen E Didonna on Sep 21st, 2018

    I was convinced with the research information that this was important for Type B. But I haven't experienced any significant system changes so far.

  • A Must Have For Me

    Posted by Anonymous on Oct 13th, 2017

    I am most vigilant about taking Deflect B when I know I am going to eat some avoids, such as popcorn and a sugary drink at a movie, or when eating any fast food that is chicken or i don't know what the oils are. I find it works best when used in conjunction with smoothies made with the protein powder A/B. I have very painful muscle inflammation when I neglectmthis routine and eat avoids.

  • less inflamation?

    Posted by J. Beck on Jul 5th, 2017

    I take Deflect B only when I eat foods that are recommended that I avoid. Primarily that is wheat, corn and tomatoes. Most of the time I am fairly consistent about being on my blood type diet. What I noticed was that when I forgot about taking the Deflect I was waking up with inflammation in muscles/joints. When I take it after a meal that was 'off the diet', I am not having that inflammation.

  • Blood Type B-skin issues

    Posted by June Harrison on Jun 11th, 2016

    I've suffered with a severe skin rash for most of my life. My skin would crack open and seep followed by blisters and intense itching. After repeated doctors could offer no solution I almost gave up. After discovering my blood type I started taking Deflect B and I am now blessed with a cure to my skin problems! No more awful skin issues. I now have normal skin, no more pain, no more hiding my horrible sores and being stared at like I had some contagious disease!!! This product has changed my life, it TRULY has! Bless you Dr. D'Adamo!

  • Great product

    Posted by Jillian on Feb 11th, 2015

    I have been using Deflect B to aid in my weightloss. I have tried everything literally to lose weight. My metabolism was at a stand still. After a few months I started losing weight to my amazement. So, far I have lost almost 30lbs in eight months. Of course, I changed my diet, and started exercising. I follow the diet plan for b+ blood type.
