2. Vitamin C

• What it does: Supports white blood cell function, helps fight off infections, and acts as a powerful antioxidant.

• Recommended daily intake: 500–1000mg for adults.

• Best forms: Ascorbic acid, liposomal vitamin C, or natural sources like rosehip and acerola.

3. Vitamin D

• What it does: Regulates immune response, supports white blood cells, and lowers the risk of respiratory infections.

• Evidence: Daily or weekly vitamin D supplementation reduces the risk of acute respiratory infections by 8–12%, especially in those with low baseline vitamin D.

• Recommended daily intake: 600–1000 IU (15–25 mcg) for adults.
