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 Muscle Building
Building muscle requires more than just lifting weights—nutrition plays an equally crucial role. The right foods provide the protein for muscle synthesis, carbohydrates for energy, and micronutrients for recovery and hormone optimization.
