Quercetin Immune Complex, 90 capsules

Quercetin Immune Complex – the Perfect Combination for Strong Immune Support: Quercetin, Vitamins C & D3, plus Zinc

Quercetin Immune Complex is an advanced formula designed to support immunity, prevention strategies, and the management of viral infections. It combines some of the most researched nutrients known for strengthening immune defense while helping reduce the duration and severity of cold, flu, and other viral respiratory infections.

Quercetin Immune Complex: A Synergistic Formula

Quercetin Immune Complex delivers a carefully balanced blend with synergistic action. Vitamin C — often called the “immunity vitamin” — enhances the effectiveness of quercetin, while quercetin acts as a zinc ionophore, helping zinc enter cells where it can exert its antiviral activity. Complementing this synergy is vitamin D3, essential for maintaining a well-functioning immune system. Together, quercetin, vitamin C, and zinc not only support immunity but may also contribute to healthy metabolism, proper circulation, and mental clarity.

Each capsule provides:

• 250 mg Quercetin
• 500 mg Vitamin C (625% NRV)
• 1000 IU Vitamin D3 (500% NRV)
• 15 mg Zinc (150% NRV)

Quercetin — A Standout Nutrient in Respiratory Health

Previously known mainly as a powerful natural anti-allergic compound, quercetin has become one of the most sought-after immune-support nutrients, used both for prevention and during viral infections. It provides antioxidant, anti-inflammatory, immunomodulatory, and antihistamine effects. In respiratory infections, quercetin may help protect against a broad spectrum of viruses, reduce illness duration, and lessen symptom severity, while supporting immune function in physically stressed individuals.

Research published in Antiviral Research (2010) reported that quercetin may inhibit replication of influenza A and B viruses.

Vitamin C, Vitamin D3, and Zinc Strengthen Immunity All Year Round

Quercetin Immune Complex also includes three essential nutrients that play a key role during respiratory infections:

• Vitamin C, often called the “immunity vitamin,” supports cellular immune defense (antiviral, antibacterial, antitumoral) and helps enhance the body’s natural resistance against pathogens.
• Vitamin D3 supports immune system regulation by contributing to the activity of monocytes — a group of white blood cells involved in fighting infections — and helps maintain balanced immune responses.
• Zinc contributes to normal immune function and supports innate immunity. Research suggests that zinc supplementation may help reduce the duration of common colds.

Quercetin Immune Complex is a food supplement.
