Bacteria are the source of blue-green algae. Although they don't contain any more protein than milk or meat, they can be utilized as a source. Pigments rich in protein, iron, and other minerals are produced by blue-green algae. Blue-green algae is used as a protein supplement and a treatment for high blood pressure. It is also used to treat diabetes, obesity, high blood levels of cholesterol or other fats (lipids), and a host of other illnesses. However, these additional uses are not supported by solid scientific data. Certain goods made from blue-green algae are cultivated in regulated environments. Numerous bioactive substances are produced by cyanobacteria. Others are grown in their natural habitat, where contamination is more likely to occur. Use only items that have undergone testing and been shown to be free of pollutants such as dangerous microorganisms, heavy metals, and liver toxins called microcystins. An outline of blue-green algae's health-promoting properties against inflammatory and metabolic disorders is given in this review.
