📋 Every biomedical protocol in one single book

Not theory about behaviors.
PROTOCOLS that reduce symptoms.

🧭

You understand what's happening biologically to your child

Stop searching Facebook groups and random blogs. The book explains with real science which metabolic pathways are compromised and why that translates into specific symptoms.

→ Scientific clarity in plain English
📋

You know exactly which tests to request from the doctor

FRAT, MTHFR, OAT — what each measures, how to order it, how much it costs, and how to interpret results to guide the protocol.

→ Walk into the appointment prepared
💊

You have documented supplementation protocols

Leucovorin, methylfolate, magnesium, CoQ10, omega-3 — what each does and when it's indicated, according to published evidence from Dr. Richard Frye and Dr. Martha Herbert.

→ Protocols, not guesswork
🥗

You change diet with a scientific foundation

Which foods inflame the autistic brain, which help, the GFCF protocol and the validated nutritional pyramid. Every decision backed by evidence.

→ Diet that amplifies the protocol
🦠

You restore your child's gut health

Full 5Rs protocol, microbiota, intestinal permeability and the gut-brain axis documented by Dr. Alessio Fasano. Without the gut, nothing else works.

→ The foundation of the biomedical protocol
⏱️

You save months of searching and hundreds of dollars

200 pages with everything you need in one place. The same information available to families who can read the original research — organized and ready to bring to your doctor.

→ An investment that saves time and money
What makes this book different

PROTOCOLS.
Not empty theory about behaviors.

This book doesn't talk about behavioral techniques or therapeutic games. It talks about biology. About reducing inflammation, correcting nutritional deficits and supporting compromised metabolic pathways with protocols that science validates.

🧬 Methylation & folate 🦠 Microbiota & permeability ⚗️ Oxidative stress 🔬 Mitochondrial dysfunction 🛡️ Heavy metals 🥗 Anti-inflammatory nutrition 💊 Documented supplementation 🧪 Tests: FRAT · MTHFR · OAT

What you'll find inside

💊

Leucovorin and Methylfolate

What they are, how they work in the autistic brain, when they're indicated and what the published evidence says according to Dr. Richard Frye.

🧪

The tests you need to order

FRAT test, MTHFR and OAT explained step by step. What each measures, where to order them, how much they cost and how to interpret results with your doctor.

🥗

Nutrition and diet

Which foods inflame the autistic brain and which help. GFCF protocol, gluten-free, dairy-free, and the validated nutritional pyramid.

🦠

Gut, microbiota and beyond

The complete 5Rs gut protocol, parasite clearance, intestinal permeability, essential supplements and the gut-brain axis with research from Dr. Alessio Fasano.

Everything you need in one place

🧠

Cerebral Folate Deficiency

Complete diagnosis and treatment protocol with leucovorin according to Dr. Frye and Dr. Quadros.

🔬

Mitochondrial Dysfunction

CoQ10, carnitine and Dr. Rossignol's studies on cellular energy and autism.

🌿

5Rs Gut Protocol

Remove, Replace, Reinoculate, Repair, Rebalance — applied to the gut of the child with autism.

🧬

MTHFR and Methylation

Variants C677T and A1298C, their impact on the autistic brain and when to use methylfolate vs leucovorin.

⚗️

Oxidative Stress

Glutathione, N-acetylcysteine and the antioxidants with the most published evidence in autism.

🛡️

Heavy Metals & Detox

What the science of Grandjean and Landrigan says about neurotoxins and how to support detoxification.

💤

Sleep and Melatonin

Sleep regulation protocols based on the biochemistry of tryptophan and melatonin.

🧲

Magnesium and Cofactors

Forms of magnesium that cross the blood-brain barrier and the essential cofactors of folate.

Guide for Talking to Your Doctor

What to ask, how to ask it and what to say so your doctor understands and supports the protocol.

How do I know if my child needs folate?
These are the tests.

Before starting any protocol, you need to confirm whether a real deficiency exists. The book explains each of these tests in detail — how to order them and what each result means.

Test 1
FRAT Test
Folate Receptor Antibody Test · CPT 0399U · fratnow.com
Detects whether antibodies are blocking the folate receptor in the brain. The most specific test for indicating leucovorin therapy.
HSA/FSA Eligible
Test 2
MTHFR
Methylenetetrahydrofolate reductase gene · Variants C677T and A1298C
Evaluates whether the body correctly converts folic acid into its active form. Key for choosing between leucovorin or methylfolate.
Standard genetic panel
Test 3
OAT
Organic Acids Test · Organic acids in urine
Global view of metabolism: mitochondria, folate, gut and nervous system. Urine sample only — no blood draw required.
Urine sample only
💡 Did you know? These tests can be paid with your HSA (Health Savings Account)

The FRAT, OAT and other specialty diagnostic tests used in biomedical autism protocols are typically eligible for payment with a Health Savings Account (HSA) or Flexible Spending Account (FSA). This means you can use pre-tax dollars — effectively reducing your out-of-pocket cost by 20–35% depending on your tax bracket. Always verify eligibility with your HSA provider.

This is not an opinion.
This is what science already knows.
