As consumers increasingly seek natural approaches to immune health, certain plant extracts have emerged as leaders based on clinical evidence.
1. Quercetin
Natural antihistamine that reduces upper respiratory infection duration by 25-30% when combined with vitamin C and zinc.
2. Berberine
Broad-spectrum antimicrobial that modulates gut microbiome, crucial for immune function since 70% of immune cells reside in the gut.
3. Curcumin
Anti-inflammatory that regulates immune responses and prevents excessive inflammation.
4. Resveratrol
Activates SIRT1, which regulates immune cell aging and enhances natural killer cell activity.
5. Epimedium Extract (Icariin)
Immunomodulatory effects through T-cell proliferation and cytokine balance.
Formulation Synergy
For comprehensive immune support, combine quercetin (500mg), vitamin C (500mg), zinc (15mg), and berberine (300mg).
