Glutathione is found in every single cell of your body. Because it's present in every cell, glutathione isn't stored in just one "reserve"-your body makes it on demand to help maintain balance (homeostasis) in the face of everyday stressors like environmental toxins, strenuous exercise, or simply the natural aging process.

Oxidative stress happens when the production of free radicals—highly reactive molecules from normal metabolism, environmental toxins, or lifestyle factors—outpaces your body’s ability to neutralize them.

Glutathione is your body's primary intracellular antioxidant, working inside cells to keep free radicals in check. But when oxidative stress is high, your cells use up glutathione faster than they can replace it.

Over time, this can:

• Deplete cellular glutathione levels, weakening your cells’ natural defenses
• Leave proteins, fats, and DNA vulnerable to damage
• Disrupt energy production in your mitochondria, creating a cycle of even more oxidative stress

Supporting healthy intracellular glutathione levels is key to helping your cells maintain balance in the face of this constant oxidative challenge.

Think of whole blood glutathione as what's floating around in your bloodstream, while cellular glutathione is what's actually inside your cells—where the real protection happens. The concentration of glutathione inside healthy cells is hundreds to thousands of times higher than in the blood outside the cells.

Glutathione is made inside your cells through a two-step enzymatic process. When you take glutathione orally, it faces two big roadblocks:

1. Digestive Breakdown - Your stomach and intestines break glutathione down into its individual amino acids before it's absorbed. That means very little-if any-intact glutathione reaches your cells.
2. Concentration Barrier - Even if glutathione does enter your bloodstream, the level inside healthy cells is already hundreds to thousands of times higher than in your blood. This steep gradient prevents glutathione from passively diffusing into cells.

As a result, most of the glutathione you swallow never becomes intracellular glutathione, where it's needed to support healthy cell function. That's why strategies that deliver glutathione's immediate precursor—like Glyteine® - are more effective for elevating cellular levels.

Homeostasis is your body's way of keeping everything in balance-like a thermostat that keeps the temperature just right. It regulates countless processes, including how much glutathione your cells make.

When your body is at homeostasis, your cells only produce enough glutathione to meet normal, everyday needs. Even if stress, toxins, or aging increase your demand, your body's "set point" won't automatically raise production.

That's why simply taking glutathione or its common precursors often doesn't boost intracellular glutathione levels—you're still working within your body's built-in limits. Understanding homeostasis helps explain why unique approaches, like delivering glutathione's immediate precursor Glyteine®, can bypass this control loop and raise cellular levels above the normal baseline.

Focus not just on glutathione, but on cellular glutathione for the following reasons:

Glutathione does its most important work inside your cells—not in your blood. That's where it helps maintain normal cellular health by:

• Neutralizing harmful free radicals before they can damage DNA, proteins, and cell membranes
• Supporting your body's natural detoxification processes
• Recycling other key antioxidants like vitamins C and E

If your cellular glutathione levels drop-whether from aging, environmental toxins, strenuous exercise, or other stressors-your cells become more vulnerable to oxidative stress. This imbalance can disrupt mitochondrial energy production and trigger a chain reaction of cellular damage.

That's why measuring or boosting only whole blood glutathione isn't enough. For meaningful support, you need to help maintain healthy intracellular glutathione, where it's actively defending your cells every second of the day.

Cellular glutathione is like your body's built-in defense shield. Found in every cell, it plays a vital role in maintaining day-to-day wellness by:

• Neutralizing free radicals before they can damage DNA, proteins, and cell membranes
• Supporting natural detoxification, helping cells process and remove unwanted compounds
• Recycling other antioxidants like vitamins C and E so they can keep working
• Protecting mitochondria, your cells' energy powerhouses, so they can keep producing the fuel you need for every function

Glutathione is made inside your cells in a two-step enzymatic process. The rate-limiting step—joining glutamate and cysteine to form gamma-glutamylcysteine (GGC)-is tightly controlled by your body's homeostasis "set point".

Because of this, simply taking glutathione or common precursors like cysteine doesn't reliably raise intracellular glutathione-your body won't make more than it thinks it needs.

The only proven way to elevate cellular glutathione above its normal baseline is to supply GGC directly. Once inside the cell, GGC bypasses the homeostatic control step and is quickly converted to glutathione by the enzyme glutathione synthase.

Glyteine®-the proprietary form of GGC in Continual-G®-is the only ingredient clinically proven to raise cellular glutathione levels above homeostasis with a single dose and in under two hours.

Glyteine® is the proprietary, clinically studied form of gamma-glutamylcysteine (GGC)-the immediate precursor your body uses to make glutathione.

Unlike other supplements, Glyteine® bypasses your body's normal "production cap" (homeostasis) on glutathione. Once inside your cells, Glyteine® is rapidly converted to glutathione by the enzyme glutathione synthase—helping raise intracellular glutathione levels above baseline in under two hours.

Gamma-glutamylcysteine is:

• Naturally occurring in all living cells
• Safe at any dose in research studies

Glyteine® is present only in Continual-G® range of supplements.

Your body makes glutathione in two steps inside the cell. The first step-combining glutamate and cysteine to form gamma-glutamylcysteine (GGC)-is controlled by a feedback loop called homeostasis, which prevents cells from making more than their baseline amount.

Glyteine® is GGC. When you consume it, it:

1. Enters your cells directly without triggering the body’s production limit.
2. Bypasses the homeostatic “bottleneck” in glutathione synthesis.
3. Is rapidly joined with glycine by the enzyme glutathione synthase to form glutathione.

Glyteine® is available exclusively in Continual-G® dietary supplements, offered in two convenient formats:

• Continual-G® Sachets - Single-serve powdered drink mix you dissolve in water for rapid absorption.
• Continual-G® Capsules - Easy-to-take capsules for those who prefer a non-powder option.

Both formats are designed to deliver Glyteine® efficiently so it can enter your cells and be converted into glutathione—helping raise intracellular glutathione levels above baseline in under two hours.

Currently, Continual-G® is the only supplement in the world that contains Glyteine®.
