Spirulina (dietary supplement)

Information about Spirulina as a dietary supplement

Spirulina is a biomass of cyanobacteria (blue-green algae) that can be consumed by humans and animals. The three species are Arthrospira platensis, Arthrospira fusiformis, and Arthrospira maxima. Cultivated worldwide, spirulina is used as a dietary supplement or whole food. It is also used as a feed supplement in the aquaculture, aquarium, and poultry industries.

Nutritional content

Spirulina contains an array of nutrients, including protein, vitamins, and minerals. It is particularly rich in protein, providing all essential amino acids. It is also a source of vitamin B1, vitamin B2, vitamin B3, copper, and iron.

Health benefits

Spirulina is often marketed as a "superfood" due to its high nutrient content. Some studies suggest that it may have antioxidant and anti-inflammatory effects. It is also believed to help lower cholesterol levels, improve immune system function, and enhance endurance.

Potential side effects

While spirulina is generally considered safe, it can cause adverse effects in some individuals, such as allergic reactions, headaches, and insomnia. People with phenylketonuria (PKU) should avoid spirulina due to its high phenylalanine content.

Cultivation

Spirulina is cultivated in open-channel raceway ponds, where paddle wheels agitate the water to prevent sedimentation. It requires alkaline water and sunlight for optimal growth.
