🌿 1. Citrus Fruits (Vitamin C Powerhouses)

Oranges, lemons, grapefruits, and limes are loaded with vitamin C, which helps increase the production of white blood cells—key to fighting infections.

Try this weekly:

• Orange or grapefruit with breakfast
• Fresh lemon juice in warm water every morning

🍊 Bonus: Vitamin C also helps your skin stay firm and radiant.

🧄 2. Garlic (Nature’s Antibiotic)

Garlic contains allicin, a sulfur compound that boosts immune response and has antimicrobial effects. It also supports heart health.

Try this weekly:
