Resveratrol & Quercetin with Grape Seed Extract: Synergistic Antioxidants For Longevity, Circulation and Cellular Health – Natural Anti-Inflammatory Protection and Mitochondrial Vitality

Resveratrol & Quercetin with Grape Seed Extract, Swanson is a complex antioxidant supplement, formulated with quercetin 250 mg, resveratrol 100 mg and grape seed extract 100 mg (standardized to 95% polyphenols) – a synergistic combination designed to support cellular longevity, healthy circulation, natural immunity and protection against oxidative stress. Each of these compounds acts at molecular level, reducing inflammation, neutralizing free radicals and supporting mitochondrial function, resulting in a cumulative effect of energy, clarity and biological vitality.

This premium formula from Swanson harnesses the power of natural plant antioxidants: quercetin, a bioflavonoid with anti-inflammatory action; resveratrol, renowned for its role in activating longevity genes; and grape seed extract, a concentrated source of proanthocyanidins, with proven effects on vascular health and cellular DNA protection.

Through their combination, these three ingredients act synergistically to reduce oxidative stress, strengthen the cardiovascular system, protect the brain and slow cellular aging processes, offering complex support for maintaining daily well-being.

Detailed Benefits of Resveratrol & Quercetin with Grape Seed Extract

• Antioxidant protection and free radical neutralization

Free radicals resulting from stress, pollution, radiation and metabolism can damage cellular DNA, lipids and proteins, contributing to aging and chronic inflammation.
✅ Quercetin and resveratrol act as antioxidant shield, protecting cells against premature oxidation.
✅ Grape seed extract adds polyphenols and proanthocyanidins, known for antioxidant power superior to vitamin C and E.
✅ Together, these components reduce oxidative stress and support the body's natural detoxification.

Through these effects, the supplement contributes to slowing aging processes, preserving vitality and protecting essential cellular structures.

• Cardiovascular health and optimal circulation

Resveratrol, derived from Polygonum cuspidatum root, is renowned for its benefits on the vascular system and heart.
✅ Helps maintain blood vessel elasticity and reduce endothelial inflammation, preventing arterial wall deterioration.
✅ Quercetin contributes to blood pressure balance and improved peripheral blood flow.
✅ Grape seed extract supports capillary integrity and tissue oxygenation.

Through these mechanisms, the combination supports efficient circulation, optimal cellular nutrition and heart health, being a reliable ally for cardiovascular system vitality.

• Longevity gene activation and DNA protection

Resveratrol is recognized for its ability to activate sirtuins (SIRT1) – enzymes involved in DNA repair, energy metabolism and cellular longevity.
✅ Stimulates cells' natural repair mechanisms.
✅ Protects DNA against deterioration caused by free radicals.
✅ Contributes to slowing biological aging and maintaining vital functions at cellular level.

In combination with quercetin, which amplifies resveratrol bioavailability, the result is a more powerful and lasting anti-aging action.

• Support for cognitive function and mental clarity

Lipid oxidation and chronic inflammation can affect neurons and cerebral blood flow.
✅ Resveratrol and quercetin cross the blood-brain barrier, offering neurocellular protection.
✅ Improve cerebral microcirculation, supporting memory, concentration and reaction speed.
✅ Grape seed extract contributes to brain oxygenation and neuronal balance.

This synergistic effect supports mental clarity, alertness state and cognitive resistance against daily stress.

• Chronic inflammation reduction and immune support

Low-grade inflammation is a common cause of numerous degenerative conditions.
✅ Quercetin is one of the most powerful natural inflammation modulators, reducing proinflammatory enzyme activity (COX and LOX).
✅ Resveratrol acts on NF-kB pathways, diminishing oxidative stress and cellular inflammation.
✅ Grape seed extract amplifies antioxidant defense, supporting the immune system against external aggressions.

Through this mechanism, the body is better prepared to respond to metabolic stress and chronic inflammation, maintaining a general state of balance and vitality.

• Skin health support and collagen protection

Polyphenols and flavonoids contribute to maintaining skin elasticity and radiance by protecting collagen and elastin.
✅ Quercetin and resveratrol reduce collagen degradation caused by free radicals.
✅ Grape seed extract stimulates skin microcirculation, improving skin tone and hydration.
✅ The antioxidant effect reduces premature aging signs and pigmentation spots.

Through these actions, the supplement contributes to more radiant, firmer and younger-looking skin from within.

• Metabolism support and mitochondrial energy

Mitochondria are the cell's "power plants," and oxidative stress can damage them.
✅ Resveratrol stimulates mitochondrial biogenesis and energy efficiency.
✅ Quercetin supports glucose oxidation and lipid metabolism.
✅ Polyphenols from grape seed extract contribute to protecting mitochondria against oxidative deterioration.

The result is constant cellular energy, vitality and increased resilience against fatigue.

• Synergies and superior bioavailability

Quercetin, beyond its own benefits, increases resveratrol absorption and stability in the body.
✅ This synergy offers prolonged and profound action at cellular level.
✅ Grape seed extract completes the effect with vasoprotective flavonoids, consolidating antioxidant benefits.
✅ Together, they form a "triangle" of protection – cellular, vascular and metabolic.

• Liver support and detoxification processes

Resveratrol and quercetin favor toxic compound elimination and support liver antioxidant enzyme activity (SOD, catalase, glutathione peroxidase).
✅ Protect liver from oxidative stress.
✅ Support hepatic lipid metabolism.
✅ Contribute to a natural process of cellular purification and regeneration.

Resveratrol & Quercetin with Grape Seed Extract, Swanson represents an advanced combination of phytonutrient antioxidants that work synergistically to protect cells, support cardiovascular health and promote active longevity. With quercetin, resveratrol and grape polyphenols, the body receives complete support for energy, circulation, immunity and cellular vitality – a natural shield against oxidative stress and premature aging.
