Tesseract AuRx | ASD Medical Food

AuRx is Tesseract Medical Research’s medical food for children and adults on the autism spectrum: stabilised butyric acid in a palatable, hypoallergenic powder, formulated for the short-chain fatty acid and gut microbiome imbalances that so often travel with ASD.

How AuRx Works

In ASD, fibre metabolism in the gut often produces abnormally high levels of propionic acid — a short-chain fatty acid that can cross the gut-brain barrier and set the stage for a toxic environment, physically and emotionally. It has been shown that the greater the GI disturbance in autistic children and adults (constipation, diarrhoea), the greater the risk of behavioural problems, language impairment and irritability. AuRx answers with butyric acid, the beneficial short-chain fatty acid, delivered as a single pure molecule and carried by Tesseract’s CyLoc and DexKey technology — trapped for the journey, released at the right point, highly absorbable.

Key Ingredients

Three components, one job each:

• Stabilised butyric acid — the beneficial short-chain fatty acid itself, supplied as a soluble, pure, individual free fatty acid.
• CyLoc dextrin-fibre matrix — the molecular trap that holds each butyric acid molecule until it is released in the gut.
• DexKey release agent — the key that opens the trap at the right point, for maximum absorption.
• Plant-derived enzyme — the only other ingredient on the label, there to help the matrix do its work.

Who It’s For

AuRx is for families navigating ASD where the gut keeps sending signals — constipation, diarrhoea, hard days that start in the belly. It is hypoallergenic by design, and families use it daily: consistency is where the difference shows.

Prefer to hear it from a family who’ve seen it up close? Joey’s parents describe the differences they noticed in their son’s speech, hand-eye coordination, behaviour and social interactions after a few months of AuRx in his daily diet:

Suggested Use

Mix one to two scoops in water or sprinkle over food, two times daily, as directed by your physician. One scoop is about 825 mg; the jar holds 68 servings. AuRx is a medical food, intended for use under medical supervision. Store tightly sealed in a cool, dry place.

Frequently Asked Questions

Does AuRx smell or taste like butyric acid? No — butyric acid is notorious for both, and masking them is exactly what the CyLoc trap is for. Mixed into water or with food, it goes down without a fight.

What makes AuRx different from a regular butyrate supplement? AuRx is a medical food, not a supplement: its butyric acid comes as a single free molecule in the CyLoc matrix — soluble, highly absorbable, and formulated for the specific nutritional requirements of ASD.

How long before we might notice changes? Every child is different. In Joey’s story — the video above — his parents talk about a few months of consistent daily use before the differences added up.
