Some types of microalgae offer interesting applications in the field of human nutrition. Today, we already have high-volume markets for Spirulina, Chlorella, Dunaliella and Haematococcus which are sold in different forms: tablets, capsules and liquids, besides as condiments and additives.
These products are being marketed worldwide as highly nutritional dietary supplements, due to its high content in proteins, vitamins, carotenoids, antioxidants and other substances highly beneficial to human health. These microorganisms are also an important source of high quality essential amino acids (Methionine, Threonine and Tryptophan), containing all essential amino acids mankind needs.
As well as being more digestible, some of these microalgae are also the original source of polyunsaturated fatty acids, with considerable levels of: EPA, DHA, ARA & ALA.
Additionally, by including microalgae in animal feed, we are able to improve palatability and increase nutritional quality, as well as partially avoiding dependence on the frequent price fluctuations in fish meal and traditional oils.
