Spirulina is a blue green algae and is a complete protein. It's nature's highest source of chlorophyll pigment, rich in such chelated minerals as iron, calcium, zinc, potassium, and magnesium. It is also a fine source of vitamin A and B-complex vitamins, and it contains phenylalanine, which acts on the brain's appetite center to decrease hunger pangs-while keeping your blood sugar at the proper level. Spirulina is a wonderful aid for weight reduction. Take three 500mg. tablets one-half hour before meals. Once the dosage begins to work, decrease to two or one tablet before meals. Spirulina is one of the many herbs found in GreenGold Nutrition.
