What is The Posey Protocol?

The Posey Protocol is a research-informed, parent-friendly roadmap for supporting children on the autism spectrum using functional genomics, detox support, neuroplasticity tools, and individualized care.

At its core, it’s about meeting each child’s body where it is — and walking forward gently, layer by layer, toward resilience.

Step One:

Comprehensive Genomic Testing

We start by analyzing 800+ genes in over 30,000 combinations to understand your unique genetic blueprint.

Focus on detoxification pathways, methylation, neurotransmitter regulation, mitochondrial health, and hormonal balance.

This allows us to identify the root causes affecting your body’s function and create a fully personalized healing plan.

Step Two:

Precision Detox

Using insights from your genes, we design a targeted detox protocol:

Focus on your specific Phase I & Phase II detox pathways.

Support glutathione, NQO1, GST, and SULT enzymes where needed.

Protect the liver, balance estrogen metabolites, and clear accumulated toxins safely and effectively.

Step Three:

Nutritional Optimization

We customize your nutrition based on how your body processes vitamins and minerals:

Correct deficiencies revealed by your genomic profile.

Support methylation, mitochondrial function, and antioxidant capacity.

Optimize your DHEA-S, cortisol, vitamin D, and other hormonal pathways through precision supplementation.

Step Four:

Neurological Foundation Check

We assess for retained primitive reflexes, which can interfere with neurological development and optimal function:

Address any primitive reflex integration issues.

Improve brain-body communication for better cognitive and behavioral outcomes.

Step Five:

Advanced Cleansing

Once your body is primed and strong enough, we safely begin deeper detoxification:

Heavy metal cleansing tailored to your genes (e.g., SLC39A8, SLC30A10, MTs).

Parasite cleansing where indicated.

This phase is introduced only after the detox pathways are optimized to avoid overloading your system.

Step Six:

Reevaluate and Level Up

Healing happens in layers. After completing your initial protocol:

We reassess genomic-driven biomarkers and functional lab results.

Adjust your plan based on your progress.

Move you to the next level of healing by refining detox, nutrition, and neurological support.

The Posey Protocol isn’t a one-size-fits-all checklist —

it’s a layered, responsive roadmap.

This is not a one-size-fits-all approach — it’s a precision, gene-guided process designed to:

Identify the root causes hidden in your DNA

Personalize detox and nutrition

Rebuild neurological foundations

Restore balance and vitality step by step
