Schizochytrium powder - It is a powder that is made from microalgae (Schizochytrium sp.), and is highly nutrient-dense, especially packed with polyunsaturated fatty acids (docosahexaenoic acid, or DHA). The powder is made from spray drying and usually comes as a powder of fine white or pale yellow, with a distinctive odor. Schizochytrium powder is widely used in animal feed, food supplements and nutraceuticals because of its DHA content and health benefits.
