Spirogyra contains a variety of essential nutrients and is a valuable source of high-calorie food. In the related green algae Cladophora and Microspora protein content is about 20 g per 100 g, and the fiber content is similar to that in common green leafy vegetables. In addition, the two genera also contain vitamins and essential minerals such as vitamin B1 and B2. Levels of vitamins, calcium and especially selenium, which is an antioxidant, are found at higher levels than in green leafy vegetables (Peerapornpisal, Makonkawkeyoon et al., 2005).
