- Nourish Your Body: Consume iron-rich foods in the days leading up to your donation. Leafy greens, lean meats and legumes are excellent choices that enhance the quality of your donated blood.
- Prioritize Rest: A good night's sleep prior to your donation is essential. Being well-rested contributes to a successful and positive donation experience.

Don'ts Before Your Blood Donation
- Never Skip Meals: Donating blood on an empty stomach is discouraged. Proper nutrition provides the energy needed for the donation and helps prevent fatigue and dizziness.
