Glutathione, Cysteine & C – Synergistic Antioxidants for Detoxification, Immunity, Cellular Energy and Skin Radiance

Glutathione, Cysteine & C, Life Extension brings together three pillars of antioxidant protection in a formula designed for an active and demanding lifestyle. Each serving provides Vitamin C 500 mg (556% NRV), Setria® L-Glutathione (reduced) 50 mg and L-cysteine HCl 200 mg, in a matrix designed to support endogenous antioxidant networks, to replenish cellular glutathione and to support phase II hepatic detoxification. Vitamin C regenerates key antioxidants (including glutathione in its reduced form), L-cysteine provides the main "building block" (sulfur amino acid) for internal glutathione synthesis, and reduced glutathione Setria® offers direct support for cellular reserves, elegantly completing the body's defensive circuit.

Through this synergy, the formula targets cellular resilience, immunity, mental clarity and the tone experienced on full days. In addition, support for glutathione – considered the "master antioxidant" – is reflected in efficient detoxification, mitochondrial protection, redox balance and well-groomed skin appearance, visible signs of a well-orchestrated metabolism.

Detailed Benefits of Glutathione, Cysteine & C, Life Extension

• Advanced antioxidant shield: networks that regenerate each other

Antioxidants do not act in isolation; they collaborate in a network:
✅ Vitamin C 500 mg neutralizes free radicals and supports the restoration of other antioxidants, including glutathione and vitamin E.
✅ Reduced glutathione (Setria® 50 mg) acts intracellularly, maintaining redox balance and protecting proteins, lipids and DNA.
✅ L-cysteine 200 mg provides the critical sulfur substrate for endogenous glutathione (GSH) synthesis.
Result: a more stable antioxidant network, capable of responding rapidly to demands.

• Hepatic detoxification and redox balance

Glutathione is central to the conjugation of unwanted compounds and their controlled elimination:
✅ Supports hepatic phase II (glutathione-S-transferases), for deactivation and excretion of toxins.
✅ Contributes to maintaining the GSH/GSSG ratio, a marker of redox status.
✅ Promotes metabolic homeostasis in demanding daily contexts.
Coherent detoxification contributes to a visible state of well-being.

• Mitochondrial protection and cellular energy

Mitochondria are highly sensitive to oxidative stress:
✅ Intracellular GSH protects the respiratory chain and mitochondrial membranes.
✅ Vitamin C reduces oxidative "noise," supporting oxidative phosphorylation efficiency.
✅ Cysteine, by supporting GSH, helps maintain the continuity of ATP production.
When mitochondria are protected, energy feels cleaner and more constant.

• Immunity and coordinated defensive response

Immune cells use glutathione intensively:
✅ GSH supports lymphocyte function and cellular barrier integrity.
✅ Vitamin C contributes to the normal functioning of the immune system and to protecting cells against oxidative stress.
✅ Synergy with cysteine promotes replenishment of the GSH reserve in busy periods.
The result is defensive resilience suited to the modern rhythm.

• Mental clarity and neuronal protection

The brain consumes a lot of oxygen and is vulnerable to oxidation:
✅ GSH participates in neuronal protection and maintaining neurotransmitter balance.
✅ Vitamin C supports the synthesis of certain mediators and antioxidant flow in nervous tissue.
✅ Results in cognitive coherence, more linear attention, mental comfort over long durations.
A protected neuronal environment promotes focus in multitasking.

• Skin, collagen and "radiance from within"

Skin faithfully reflects the internal state of tissues:
✅ Vitamin C contributes to normal collagen formation, supporting firmness and elasticity.
✅ Intracellular GSH protects the extracellular matrix from oxidative degradation.
✅ The synergy reduces the impact of daily stressors, contributing to a well-groomed and uniform appearance.
It is a holistic approach to beauty from within.

• Comfort after exertion and muscle protection

Intense exercise generates free radicals:
✅ GSH and vitamin C limit the oxidation of muscle proteins and lipids.
✅ Cysteine helps restore the GSH reserve after training.
✅ This translates into the perception of better comfort in periods of high activity.
Thus, movement remains pleasant, with smoother recovery.

• Cell barrier and membrane integrity

Antioxidants support cell membrane stability:
✅ GSH protects protein thiols and maintains the structure of membrane enzymes.
✅ Vitamin C helps regenerate vitamin E, an important shield for membrane lipids.
✅ The synergy reduces lipid peroxidation and supports membrane transport.
Cells maintain their functionality in dynamic environments.

• The sensation of "lightness" on full days

Disorganized oxidative stress means sluggish transitions between tasks:
✅ The GSH–Vitamin C–Cysteine network "smooths" oxidative peaks.
✅ Results in metabolic coherence and predictable tone.
✅ Good redox support feels like daily fluidity.
It's the discreet difference between "just keeping pace" and performing consistently.

• Traceability and dose quality

The formula clearly states the active content:
✅ Vitamin C 500 mg (556% NRV) – antioxidant core and cofactor in essential syntheses.
✅ Setria® L-Glutathione (reduced) 50 mg – direct support for cellular reserves.
✅ L-cysteine HCl 200 mg – key precursor for GSH synthesis.
The transparent composition facilitates integration into any routine.

• Intelligent synergies in daily habits

The most visible results appear when the formula is accompanied by:
✅ Adequate hydration and plant-rich diet.
✅ Sleep and recovery for restoration of antioxidant enzymes.
✅ Moderate movement for stimulating mitochondria.
Together, these habits amplify the benefits of the antioxidant network.

Glutathione, Cysteine & C, Life Extension offers a complete antioxidant "triangle": Vitamin C 500 mg, Setria® L-Glutathione 50 mg and L-cysteine 200 mg. Through mitochondrial protection, efficient detoxification, immunity and mental clarity, the formula creates conditions for stable energy and a well-groomed skin appearance – a sign of well-conducted redox balance, suited to modern life and your daily goals.
