Food Sensitivity Test in Houston, TX
Find out which foods are quietly driving your bloating, fatigue, brain fog, or skin issues — a physician-reviewed at-home test measuring IgG + Immune Complex reactivity to up to 176 foods.
A Root-Cause Look at Chronic Inflammation
Food-driven inflammation affects more than 100 million people worldwide. Unlike a food allergy, it damages the integrity of your gut lining — leading to intestinal permeability, or Leaky Gut Syndrome — and can quietly drive a wide range of chronic, hard-to-diagnose conditions.
The solution? Test, don't guess.
The FIT Test is a patented, multi-pathway test that measures both IgG antibodies and Immune Complexes — the two most common food-related immune pathways — detecting your body's adaptive and innate reactions to food.
After your results are ready, you'll receive a personalized meal plan built around your "safe" foods — so you never feel deprived or overwhelmed by elimination.
Good to know: this test measures food sensitivity specifically — not food allergy (an immediate IgE reaction, diagnosed by an allergist) or food intolerance (a digestive enzyme issue). See the FAQ below for details.
