What is Glutathione?

The Body's Master Antioxidant

Glutathione is often called the "Master Antioxidant" of the body. It plays a crucial role in protecting cells from damage, detoxifying the body, and supporting the immune system. Glutathione is actually made by your body and appears in each any every single cell. Here’s the key - all other antioxidants depend on glutathione for their proper function!

Glutathione is found in every cell of the body and is essential for:

Antioxidant Protection

Glutathione neutralizes free radicals and oxidative stress, preventing cell damage that contributes to aging, inflammation, and chronic diseases.

Strengthening Immune Function

As the body’s primary immune defense, glutathione helps strengthen white blood cells and supports the body's ability to fight off infections and illnesses.

Detoxification & Liver Health

Glutathione acts as the body's most important detoxifier, helping the liver remove heavy metals, toxins, and pollutants from the bloodstream. It plays a key role in eliminating harmful substances from our environment, food, and even medications.

Energy Production & Cellular Function

Mitochondria, the powerhouses of our cells, rely on glutathione for optimal energy production, preventing fatigue and premature cell damage.

Brain & Cognitive Support

Glutathione helps protects neurons from oxidative stress, supporting brain function, memory, and mental clarity. Low levels of glutathione have been linked to neurological conditions like Alzheimer's and Parkinson's.

Muscle Recovery & Athletic Performance

Athletes and fitness enthusiasts rely on glutathione to reduce muscle fatigue, accelerate recovery, and combat inflammation after intense workouts.

Glutathione levels naturally decrease with age and are further depleted by: Poor diet and processed foods, chronic stress, exposure to toxins, pollution, and heavy metals, excessive alcohol or tobacco use, illness and inflammation, and aging.

Since the body makes glutathione itself, the best way to boost glutathione naturally is through a glutathione precursor like Immunocal (the only one of its kind), which provides the necessary building blocks (Bonded Cysteine™) to allow the body to produce its own glutathione efficiently.

Why Is Glutathione Called the “Master Antioxidant”?

Glutathione is the foundation of the body’s antioxidant defense system, as it recharges and enhances the power of other antioxidants, like Vitamin C and E.

Here’s how it works:

1. Vitamin C fights free radicals but becomes inactive after use (like a drained battery).
2. Glutathione “recharges” and “recycles” Vitamin C, keeping it active and effective.

Without glutathione, other antioxidants wouldn’t function properly, making it essential for strong immunity, a healthy body, and overall vitality. Finally, glutathione is made naturally by the body itself, other antioxidants must come from dietary sources.

How Does Glutathione Work in the Body?

Glutathione neutralizes harmful molecules, reducing inflammation and protecting cells from damage that leads to aging and disease. What are just some of the primary benefits of increasing glutathione?

• Stronger Immunity: Enhances white blood cell function
• Antioxidant Protection: Shields against free radicals
• Detoxification: Removes toxins, heavy metals, and pollutants
• Energy Boost: Fuels mitochondria for better stamina
• Brain & Cognitive Support: Reduces neurodegeneration
• Faster Recovery: Supports muscle repair and performance

Why Can't You Just Take Glutathione?

"One of the greatest myths surrounding glutathione is that you can raise your glutathione levels by eating glutathione. Time and again, this has been shown to be a very inefficient way to do this.

Glutathione is made by your own cells, and the way to achieve this is to feed your cells the specific nutrients (precursors) so that your own body can make glutathione. This is what Immunotec is defined as in major medical resource textbooks—a ‘Glutathione Precursor.’”

- Dr. Jimmy Gutman, World Leading Authority on Glutathione

This is why glutathione supplements alone are not enough. The body breaks down pre-made glutathione before it can be absorbed. The most effective way to raise glutathione is with a glutathione precursor—a supplement that provides the essential building blocks for your body to naturally produce and regulate its own glutathione.

Health Matters, Immunocal Works

Unlike other supplements, Immunocal® is a clinically proven glutathione precursor that helps your body produce its own natural glutathione.

How it works:

• Delivers Bonded Cysteine™, the key building block for glutathione production
• Supports natural regulation so the body produces only what it needs
• Backed by 79+ patents and 45+ years of research

How Does Immunocal Compare to Other Glutathione Supplements?

What is a Glutathione Precursor?

Think of a precursor as the raw ingredients your body needs to make something important—like a recipe. Immunocal doesn’t just give you glutathione—it gives your body the key building blocks it needs to produce its own glutathione, naturally.

That’s a big deal, because your body knows how to make and regulate it better than any "quick fix" ever could. And when your body is making glutathione on its own? That’s when your cells stay strong, your energy stays high, and your natural defenses stay sharp. With Immunocal, your body makes and regulates glutathione naturally, ensuring maximum absorption and effectiveness.

Why Glutathione is Essential for Optimal Health

Glutathione is your body’s master antioxidant, immune booster, and detoxifier. However, due to natural decline in levels, supporting its production with a clinically proven glutathione precursor like Immunocal® is key to long-term health, energy, and vitality.
