The Tolerance Induction Program®:
The New Standard of Food Allergy Care
TIP is a data-driven, individualized treatment program that retrains the immune system to tolerate food. Unlike conventional protocols focused on desensitization, TIP leverages biomarker analysis, biosimilar proteins, and AI-driven treatment planning to achieve true food freedom.
-
1
Comprehensive diagnostics (IgE, IgG4, basophil, skin prick)
The Tolerance Induction Program™ (TIP) begins with a robust diagnostic process incorporating IgE, IgG4, Basophil Activation Tests (BAT), and skin prick testing. These tools allow for deep immune profiling, identifying not only the presence of food-specific IgE but also modulating markers like IgG4 and basophil reactivity. This comprehensive dataset forms the basis for individualized treatment plans and tracks immunologic shifts over time, offering clear insight into progression toward remission.
-
2
Immune system mapping with machine learning
Using trillions of data points, TIP employs a proprietary machine learning platform to map each patient’s immune system and define specific endotypes. The resulting Allergy Snapshot—a dynamic visual representation of immune sensitivity—enables real-time monitoring of progress and precision prediction of treatment response. This platform analyzes shifts in immunoglobulins and cellular responses to optimize the Food Dosing Strategy and support long-term immune retraining.
-
3
Controlled exposure using biosimilar proteins
TIP’s treatment protocol uses biosimilar proteins—non-allergenic, structurally similar proteins—to condition the immune system safely before introducing primary allergens. These proteins exploit shared IgE-binding domains across allergen superfamilies (e.g., Ara h in peanuts and related seed/tree nut proteins) to gradually shift the immune response from sensitization to tolerance. This approach significantly reduces risk, maintains reaction rates below 1%, and primes the immune system for successful allergen challenge.
-
4
Precision Protein Gummy Dosing
Allergen-specific gummies developed in TIP’s in-house lab provide highly controlled, pharmaceutical-grade dosing tailored to each patient’s unique immune profile. These microdosed gummies ensure exact protein delivery in age- and weight-adjusted amounts, supporting consistent at-home therapy. This format promotes adherence, simplifies dosing logistics for families, and enables precise immune training with minimal risk.
-
5
In-office challenges based on biomarker readiness
Food introductions and oral food challenges are conducted in-clinic only after biomarker trends—such as reductions in IgE and basophil reactivity—indicate readiness. Each challenge serves as a functional test of immune modulation, with progression determined by real-time lab data and machine learning insights. This strategy ensures safety while confirming tolerogenic milestones prior to advancing the patient through subsequent dosing phases.
-
6
Remission: ability to eat freely without daily dosing
TIP defines remission as sustained immune tolerance—seven days of unresponsiveness to allergenic proteins with weekly exposure only. Unlike desensitization protocols requiring daily maintenance, patients in remission can eat freely without label checking, reactogenic anxiety, or food avoidance. Over 8,000 patients have achieved this milestone, with long-term remission supported through gradually tapered maintenance dosing guided by follow-up labs and ongoing immune monitoring.

Founder and Medical Director of Ocean Pediatrics, Dr. Abelowitz is a leader in the field of pediatric medicine, with a vast expertise in academic and clinical settings. He has been treating children in the Orange County area for over 29 years.
“The primary challenges my patients encounter with food allergies are lifestyle limitations, anxiety, and fear related to the dangers of food allergy, especially anaphylaxis, multiple doctor and ER visits, consistent need for medication refills, especially Epipens and Avi-Q, as well as the constant, tedious need to constantly
Complete medical forms such as school allergy and medication administration forms.
Witnessing a patient overcoming their allergies is especially rewarding and heartwarming, knowing the dramatic life-changing effect it will have. Some of the notable changes I observe when children
reach remission is an overwhelming sense of relief by the patient but especially the parents, increased confidence, and reduced anxiety.”
