Spirulina Overview
Spirulina is a blue-green algae superfood providing complete protein with all essential amino acids, exceptional iron bioavailability, and potent phycocyanin antioxidants that reduce inflammation and support immune function.
Why Spirulina Helps With Immune System Support
A robust immune system depends on adequate nutrition, particularly key micronutrients involved in immune cell function and antibody production. A diet rich in colorful plants, quality protein, and fermented foods provides comprehensive immune support.

Key Nutrients in Spirulina for Immune System Support
Best Ways to Eat Spirulina for Immune System Support
- Blend 1 tsp into smoothies with banana and mango to mask earthy flavor
- Mix into fresh juices or coconut water for quick nutrient boost
- Add to energy balls or protein bars for sustained energy
