Sometimes food isn’t enough—especially during high-stress periods or seasonal transitions. These science-backed supplements can fill in the nutritional gaps and give your immune system a targeted boost.

4. Elderberry Extract
- Popular in syrup or gummy form, elderberry may help reduce symptoms of respiratory infections.
5. Quercetin + Vitamin C Combo
- A rising star in 2025: Quercetin (a plant flavonoid) combined with Vitamin C can help regulate histamine response and inflammation.
🥗 Bonus Tips: Immune-Boosting Habits That Work with Food
- Hydrate regularly – Water helps carry nutrients to your cells and flushes out toxins.
- Exercise moderately – Daily movement improves circulation and supports immune function.
- Get enough sleep – Aim for 7–9 hours to allow your body time to recover and repair.
- Limit sugar and processed foods – These can weaken your immune response over time.
