- Improve oxygen transport and blood circulation
- Support red and white blood cell production
- Repair damaged tissues and cells
- Enhance gut microbiota, which supports overall immunity
- Reduce systemic inflammation
- Strengthen the lungs and respiratory function
Superfoods contain concentrated nutrients and bioactive substances that have been shown to aid in these functions. Let’s explore the top ten superfoods for 2025 that will boost immunity.
