Immune SupportKey Benefits
How It Works
Elderberry (Sambucus nigra) anthocyanins and flavonoids directly inhibit viral entry and replication by binding to viral surface proteins. They also stimulate cytokine production to enhance immune response and provide potent antioxidant protection.
Dosage & Timing

500-1,000 mg standardised extract daily during cold/flu season
Best Time to Take
At first sign of illness: every 3-4 hours. Preventively: once daily during winter.
Recommended Form
Sambucol or standardised elderberry extract (not raw)

GI discomfort. Raw elderberries are toxic (must be cooked/processed). Previous cytokine storm concerns now considered unlikely.
