Carbohydrate Intolerance

A condition where carbs lead to fatigue, fat gain, or cravings—often driven by excess internal fructose conversion.

Carbs Aren’t the Enemy—Fructose Might Be

Carbohydrate intolerance often signals deeper metabolic dysfunction, and fructose may be the hidden culprit.

When fructose metabolism overwhelms the liver, it generates fat, uric acid, and mitochondrial stress—disrupting how the body processes all carbs, not just sugar. The result is unstable blood sugar, insulin resistance, and post-meal crashes that make carbs feel intolerable, even in small amounts.

SugarShield helps support your ability to handle carbohydrates by targeting the metabolic friction caused by fructose. By promoting healthier energy metabolism and reducing cellular stress, it helps you regain balance and flexibility—without extreme carb restriction.

What is Carbohydrate Intolerance?

Carbohydrate intolerance refers to an inability to metabolize carbs efficiently without experiencing adverse effects like blood sugar swings, weight gain, or energy crashes.

It's Not Just About Sugar

Many people blame carbs in general—but often, the issue is that carbs are being converted into fructose internally via the polyol pathway, especially under:
- High glucose loads
- Salt stress
- Inflammation or insulin resistance

This triggers the same metabolic damage as eating sugar directly.

Symptoms

- Brain fog
- Cravings
- Fat storage (especially visceral fat)
- Fatigue after meals

Why It Happens

Carb intolerance often signals that the fructose pathway is overactive—producing uric acid, depleting ATP, and promoting fat synthesis.

At LIV3, we help users regain metabolic flexibility by blocking the fructose conversion step, so healthy carbs can be used as fuel—not fat."

Luteolin: The Anti-Sugar Nutrient You’ve Never Heard Of (But Need to Know About)

Luteolin is a rare plant flavonoid shown to naturally quiet the fructose pathway—the same metabolic switch targeted by pharmaceutical fructokinase inhibitors. By protecting cellular energy and lowering uric acid and inflammation, it helps restore the stable, high-efficiency metabolism that modern diets have lost.

Huntington’s Disease Breakthrough: Gene Therapy AMT-130 and the Energy Failure Model

A new gene therapy has slowed Huntington’s disease progression for the first time — a historic breakthrough. Seen through the energy failure model, it also highlights how metabolic stress like fructose stacks on top of genetic insults, and why research on luteolin is showing promise across multiple neurodegenerative conditions.

Tylenol, Autism Risk, and Fragile Energy: What Does the Science Really Say?

The Tylenol–autism debate shows how easily developing brains can be tipped when cellular energy is fragile. Our research suggests a bigger story: the Fructose Model — a framework showing how daily sugar exposure creates the same low-energy state across the whole body.

The Fructose–Insulin Connection: What Doctors Aren’t Telling You About Weight Loss Resistance

Doctors often blame carbs in general, but that's only part of the story. To really answer what causes insulin resistance, we need to look at fructose. If the engine is the problem, pressing harder on the gas pedal won't help. Instead, the solution is to improve how the cell handles fuel and gradually rebuild insulin sensitivity.
