Why You Need Deflect
You do your best to eat right, but sometimes ‘avoids’ happen—on the road, at restaurants, or during holidays.
Unfortunately, certain foods contain lectins that can bind to your gut lining, trigger immune responses, and lead to bloating, fatigue, and more. Deflect is your daily defense—especially when food choices aren’t perfect.
Each formula is customized to your blood type to block the specific lectins most likely to affect you.
What's Inside Your Formula
Deflect A is your first line of defense against lectins that target Blood Type A. Its custom blend is designed to block A-specific lectins before they interfere with digestion, hormone balance, or immune health.
N-Acetyl D-Glucosamine (NAG)
Acts like a magnet for lectins in foods. 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.
Chondroitin
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.
D-Mannose
Has a unique structure that can prevent adhesion of certain bacteria including E. coli and influenza virus by binding to them.
Plus: Pineapple and cranberry concentrates are included to enhance absorption and support healthy gut function.
Designed For Real Life Moments
Life isn’t always predictable. Travel, takeout, busy schedules — it’s not always possible to eat perfectly. That’s why Deflect was created: to support you when your routine isn’t.
Each formula is tailored to the lectins most likely to affect your blood type, giving your gut an extra layer of protection when meals don’t go as planned. Whether it’s a work lunch, a family gathering, or just a quick snack between errands, Deflect helps you feel healthy, even when life gets messy.
