Organic spirulina is a microscopic algae that is a quality dietary supplement and a source of iron. 100% natural and organic, spirulina contains more beta-carotene, iron, vitamin B12 and gamma linoleic acid than any other food. It also contains the same amount of vitamin E as wheat, and the same amount of calcium, phosphorus and magnesium as milk. Spirulina is especially effective in helping in case of fatigue as it helps to maintain the vitality of the body and to feel more energetic. Spirulina contains antioxidant compounds (e.g. beta-carotene), which contains iron and other minerals. It has a high vitamin B12 content (3 times higher than in liver). Its high iron content makes it the perfect complement to the diet of vegetarians.
