Spirulina is a seaweed of tropical origin that is widely used in weight loss diets for its low caloric intake, high protein content and satiating properties. Its use helps to maintain the nutritional balance in low-calorie diets, without generating weakness or exhaustion. In addition, its richness in the essential amino acid, phenylalanine, present in high amounts, helps to reduce the feeling of hunger. Suitable for the elderly, athletes and convalescents. In states of malnutrition and physical exhaustion, it acts as a general tonic and revitalising the body.
