Just three grams of our organic Spirulina has the same amount of nutrients as five servings of fruits and vegetables. Spirulina has 300% more calcium than whole milk (good for bones, osteoporosis, growth of children). Spirulina has 3900% more Beta Carotene than carrots (good for eyes, strong antioxidant, immunity). Spirulina has 375% more protein than tofu (building block for muscle tissue, necessary in diet). Spirulina is a type of live blue-green algae and a natural source of small quantities of Iodine / Potassium iodide (KI). Iodine is a chemical element essential for the production of thyroid hormones that regulate growth and metabolism. Diets deficient in iodine increase risk of retarded brain development in children (cretinism), mental slowness, high cholesterol, lethargy, fatigue, depression, weight gain, and goiter: a swelling of the thyroid gland in the neck. The natural Potassium iodide (KI) / Iodine from Spirulina is absorbed by your body more slowly and safely than chemical or synthetic iodine. Further Spirulina helps promote an alkaline pH balance within the body and also boosts the immune system.
