Balance Histamine & Calm the Chaos
Naturally Stabilize Mast Cells
Say goodbye to unexplained symptoms, inflammatory flares, and histamine overload. SugarShield helps restore balance by targeting a key trigger of mast cell dysregulation—metabolic stress caused by fructose.

The Problem: Histamine Intolerance & Mast Cell Activation
Do you struggle with brain fog, hives, congestion, fatigue, or strange food reactions?
These may be signs of mast cell activation—when the immune system’s histamine-releasing cells become hypersensitive.
People with histamine issues often feel like their symptoms are random or untreatable. But research shows mast cells don’t act without reason. One powerful—and overlooked—trigger is metabolic stress.
When your cells are overloaded by sugar, especially fructose, they produce byproducts like uric acid and oxidative stress that activate mast cells, making your body more reactive and inflamed.
Mast cells are sensitive to more than allergens—they respond to environmental and internal stress, including cellular energy depletion. That’s why stabilizing your metabolism may be the missing link in calming your immune response.
FAQs About Histamine, MCAS & Metabolism
What causes histamine Intolerance?
Mast cells release histamine as part of the immune response, but in some people, they become overactive—triggered by food, stress, heat, or even spontaneous flares. A growing body of research suggests that metabolic stress from fructose may be a hidden driver of this overactivation.
What is MCAS (Mast Cell Activation Syndrome)?
MCAS is a condition where mast cells release excessive histamine and other inflammatory chemicals without a clear external allergen. Symptoms may include itching, flushing, swelling, digestive issues, or even anxiety and brain fog.
How does sugar affect histamine and mast cells?
Fructose metabolism rapidly depletes ATP (cellular energy), raises uric acid, and increases oxidative stress—all of which prime mast cells for activation. The resulting inflammation can worsen histamine intolerance and MCAS symptoms.
Can reducing sugar improve histamine Intolerance symptoms?
Yes. Many find that reducing sugar, especially fructose, can decrease their baseline inflammation and reactivity. But cravings often get in the way—especially when histamine issues are also triggering fatigue, anxiety, and brain fog.
What makes SugarShield different?
SugarShield targets the upstream driver of histamine intolerance: fructose metabolism. Its key ingredient, Luteolin, is one of the best-studied natural mast cell stabilizers—and it also blocks fructokinase, calming the root of metabolic stress.
How SugarShield Supports Histamine Balance
SugarShield supports your body’s ability to stay calm and resilient in the face of histamine triggers.
Supports Fructose Metabolism
Luteolin inhibits fructokinase, preventing fructose from draining ATP and generating inflammatory byproducts like uric acid and ROS—common mast cell triggers.
Supports Fructose Metabolism
Luteolin inhibits fructokinase, preventing fructose from draining ATP and generating inflammatory byproducts like uric acid and ROS—common mast cell triggers.
Calms the Brain & Nervous System
Luteolin is one of few compounds shown to cross the blood-brain barrier and stabilize mast cells in the brain—making it uniquely helpful for anxiety, brain fog, and sensory overload.
Stabilizes Mast Cells
Multiple studies confirm that Luteolin inhibits histamine release, reduces mast cell degranulation, and modulates inflammatory pathways—making it ideal for MCAS support.
Restores Metabolic Stability
By removing fructose’s influence, SugarShield helps restore balance across your cellular and immune systems—supporting long-term histamine resilience.

The trademark burning pain associated with fibromyalgia is all but gone - something I have suffered with for nearly 20 years. … The bloating I normally experience after a high carb meal is gone. This has definitely improved my digestion.

After a few weeks, we’ve noticed an improvement in our digestion and a boost in our immune system. … we’ve been traveling on planes/trains and around lots of people thus prone to getting sick, but so far, our immune system has kept us healthy!

Take charge of your histamine response.
When your body is under metabolic stress, mast cells are more likely to overreact—triggering histamine release and uncomfortable symptoms. By calming this stress at its root, you can restore balance and resilience. SugarShield helps support that balance, giving your immune system room to respond the way it should.
