Blue-green algae is considered a green superfood because it contains many supportive nutrients. One of these nutrients is a powerful plant-based protein called phycocyanin, which is the pigment that gives Spirulina its blue-green color. Phycocyanin may have antioxidant properties and may also enhance immune function. #californiagoldnutrition #iherb #spirulina #superfoods #supergreens #supplements #antioxidants #vegans #vegetarian #healthy #wellness
