C Extra + Quercetin Bioflavonoids 500 mg/500 mg: Advanced Immunity, Powerful Antioxidants, Respiratory Comfort & Vascular Health

 

C Extra + Quercetin Bioflavonoids, Natural Factors, is a synergistic complex designed to provide complete support for the immune system, antioxidant protection, and daily vitality. Each serving provides Vitamin C (ascorbic acid) 500 mg and Quercetin (bioflavonoids) 500 mg, in a balanced 1:1 ratio that maximizes the natural synergy between vitamin C and plant-derived flavonoids.

 

Vitamin C supports collagen formation, normal immune function, and protection of cells from oxidative stress, while quercetin completes the antioxidant spectrum and helps maintain a balanced immune response, with remarkable benefits for respiratory comfort, vascular health, and resilience to environmental factors.

 

The formula is suitable for active lifestyles, busy periods, or seasonal changes, when the body requires robust defense and rapid recovery. By combining vitamin C and quercetin, the product provides support for immunity, antioxidant protection, respiratory comfort, skin, gums, joints, and vascular health.

Detailed Benefits of C Extra + Quercetin Bioflavonoids

🛡️ Year-round Immune Fortification

Effective immunity requires a network of nutrients working together. Vitamin C contributes to the normal functioning of the immune system, supporting immune cell activity and the synthesis of mediators involved in the body's defense. Quercetin, a bioflavonoid with a strong antioxidant profile, supports a balanced immune response in the face of daily challenges.

✅ Immunity support during the cold season and demanding periods
✅ Contribution to the body's natural resilience
✅ Nutritional foundation for a rapid and balanced response

✨ Broad-spectrum Antioxidant Protection

Oxidative stress affects cells in contact with pollution, screens, physical exertion, or stress. Vitamin C, a water-soluble antioxidant, neutralizes free radicals in the aqueous environment of cells and regenerates other endogenous antioxidants. Quercetin completes this protection through its action on multiple oxidative pathways.

✅ Advanced defense against free radicals
✅ Support for daily oxidative "housekeeping"
✅ Contribution to maintaining cellular integrity

🌿 Respiratory Comfort and Histamine Balance

Seasonal changes and environmental factors can influence respiratory comfort. Quercetin is appreciated for its role in supporting histamine balance and mast cell stability, while vitamin C contributes to the normal functioning of the immune system. Together, they can help the body maintain a sense of clear and comfortable airways.

✅ Support for a balanced immune response in the respiratory tract
✅ Contribution to sinus and mucosal comfort
✅ Daily routine for periods with airborne challenges

🧼 Collagen, Skin, Gums, Joints, and Blood Vessels

Vitamin C is a key cofactor in collagen synthesis, supporting the normal structure of skin, gums, cartilage, bones, and blood vessels. Quercetin, through its antioxidant action, protects tissues against oxidative degradation. The combination supports tissue elasticity and strength.

✅ Support for collagen production
✅ Natural care for skin and gums
✅ Joint comfort and vascular health

📈 Daily Energy and Post-Exertion Recovery

A stressed body needs efficient management of free radicals resulting from intense physical or mental activity. Through its role in energy metabolism and antioxidant protection, vitamin C contributes to the reduction of tiredness and fatigue and to the normal functioning of the nervous system. Quercetin provides adaptive support under physical stress conditions.

✅ Contribution to the reduction of daily fatigue
✅ Support for faster recovery after exertion
✅ Stable energy for work, study, and sports

🧘 Cardiovascular Health and Microcirculation

Endothelial health and microcirculation depend on protection against oxidative stress. Vitamin C helps maintain normal blood vessel function, while quercetin supports vascular relaxation and oxidative balance in the endothelium. The cumulative effect encourages healthy circulation and daily cardiovascular comfort.

✅ Support for blood vessel elasticity
✅ Contribution to efficient blood flow
✅ Antioxidant protection for the cardiovascular system

C Extra + Quercetin Bioflavonoids, Natural Factors, brings together two essential ingredients in a simple and effective formula, designed for daily use. Whether you are looking for solid immunity, antioxidant protection, respiratory comfort, or vascular support, this combination is a trusted partner.
