Glutathione 500 mg – "Master" antioxidant, liver detox, immunity and cellular vitality

Glutathione 500 mg, Now Foods is a premium formula designed to support the body's redox balance, liver detoxification and antioxidant defense at cellular level. Each serving offers 500 mg glutathione in its reduced form (GSH) – the biologically active form – alongside 100 mg milk thistle extract (standardized to 80 mg silymarin flavonoids) and 50 mg alpha-lipoic acid (ALA), cofactors that support glutathione regeneration and protection against oxidative stress. The intelligent combination of glutathione, silymarin and ALA creates a "triangle" of support for liver, immunity, mitochondrial energy and skin appearance.

 

Glutathione is considered the "master antioxidant" because it directly participates in free radical neutralization, recycling of other antioxidants (vitamin C, vitamin E) and toxin conjugation for excretion. Silymarin from milk thistle offers liver and membrane support, while ALA – an amphoteric antioxidant (active in both aqueous and lipid environments) – contributes to restoring oxidized glutathione to GSH, thus supporting an efficient antioxidant cycle.

Detailed Benefits of Glutathione 500 mg, Now Foods

• Antioxidant defense at cellular level

Oxidative stress affects lipids, proteins and DNA. Reduced glutathione (GSH) acts as a front-line defense at cellular level, supporting neutralization of reactive oxygen and nitrogen species.

✅ Helps protect cells against oxidative stress;
✅ Contributes to maintaining membrane integrity;
✅ Supports recycling of other endogenous antioxidants.

• Liver detoxification and redox balance

The liver is the center of the body's "detox station". GSH participates in toxin conjugation phases, facilitating their elimination. In the formula, silymarin from milk thistle supports liver function and stabilizes hepatocyte membranes.

✅ Support for natural detoxification processes;
✅ Contributes to liver comfort;
✅ Helps maintain a healthy GSH/GSSG ratio.

• Glutathione regeneration and synergy with ALA

Alpha-lipoic acid participates in converting oxidized glutathione (GSSG) to its reduced form (GSH), keeping the "glutathione cycle" active. The GSH + ALA synergy represents an advantage in maintaining the antioxidant network.

✅ Cofactor for active GSH restoration;
✅ Supports redox balance in aqueous and lipid environments;
✅ Optimizes antioxidant response capacity in demanding conditions.

• Immunity support in daily life

Immune cells use glutathione to maintain their functionality against daily challenges. An adequate GSH level supports balanced immune response and body resilience.

✅ Contributes to normal immune cell function;
✅ Support during demanding periods;
✅ Helps maintain general well-being.

• Mitochondrial energy and vitality

Mitochondria are sensitive to oxidative stress. By protecting cellular structures and supporting redox balance, GSH and ALA can support a favorable environment for ATP production and fatigue resistance.

✅ Helps protect mitochondria;
✅ Supports energy metabolism;
✅ Contributes to a sensation of vitality throughout the day.

• Luminous skin and protection against environmental factors

Glutathione participates in cutaneous antioxidant defense, while silymarin supports regeneration processes at cellular level. By controlling oxidative stress, the formula can contribute to well-groomed skin appearance.

✅ Support for skin uniformity and luminosity;
✅ Contributes to protection against external aggressors;
✅ Helps maintain skin suppleness and comfort.

• Digestive comfort and membrane support

Silymarin stabilizes membranes and supports bile secretions, an important aspect for digestive processes and lipid solubilization. Synergy with GSH supports the general metabolic environment.

✅ Supports good hepato-biliary function;
✅ Contributes to digestive comfort;
✅ Helps with natural fat emulsification processes.

• Balance after demanding periods

Intense schedule, pollutants, training or irregular nutrition can increase antioxidant demand. By restoring intracellular GSH reserves and redox protection, the formula supports return to balance.

✅ Support for adaptation and resilience;
✅ Suitable during periods of increased oxidative stress;
✅ Contributes to functional recovery.

• Integrated antioxidant network

Glutathione is a central node of the antioxidant network, interacting with vitamins C and E, coenzyme Q10 and enzymes like glutathione peroxidase. ALA enhances this network, while silymarin offers liver "shielding".

✅ Support for endogenous antioxidant cooperation;
✅ Helps maintain antioxidant response flexibility;
✅ Holistic approach: GSH + ALA + silymarin.

• Quality, traceability and composition clarity

Now Foods utilizes standardized and precisely dosed ingredients for reproducible results. Clear labeling confirms potency: GSH in reduced form, quantified silymarin and ALA in functional dose.

✅ Glutathione (reduced form) – 500 mg per serving;
✅ Milk thistle extract – 100 mg (standardized to 80 mg silymarin flavonoids);
✅ Alpha-lipoic acid – 50 mg per serving.

• Suitable for modern wellness routines

The formula integrates easily into a care routine that includes hydration, varied nutrition and movement. Its purpose: to support, from within, natural processes of defense, detox and restoration.

✅ Complement for active lifestyle;
✅ Support for maintaining daily tone;
✅ Aligned with current cellular protection needs.
