The antioxidants in spirulina, including phycocyanin and beta-carotene, can neutralize free radicals and prevent oxidative damage.

2. Boosts Immune System

The antioxidants in spirulina not only protect the body from diseases but also boost the immune system. A strong immune system is essential for fighting off infections and illnesses.
