The products of the Marcus Rohrer brand are dietary supplements formulated on the basis of spirulina. The products are produced by the company Spirulina International.
Spirulina is a blue-green alga that is barely half a millimeter long and means "small spiral", referring to the spiral structure of algae. Spirulina is known worldwide as one of nature's richest food sources. It has a vegetable protein content of more than 60% and contains vitamins B12, K1 and K2, 96 minerals and trace elements and high levels of chlorophyll, phycocyanins and carotenoids. Spirulina provides more energy, a better resistance, a powerful detoxification and benefits for the skin, hair and nails. It also improves sports, work and learning performance.
