Spirulina is an organism that grows in both fresh and salt water. It is loaded with various nutrients and antioxidants that may benefit your body and brain. Spirulina was consumed by the ancient Aztecs but became popular again when NASA proposed that it could be grown in space for use by astronauts.
Gram for gram, spirulina may be the single most nutritious food on the planet, containing protein, vitamin B1, vitamin B2, vitamin B3, copper, iron, magnesium, potassium and manganese and small amounts of almost every other nutrient you need. Spirulina is a powerful antioxidant and has anti-inflammatory properties. Research has also found that spirulina may lower bad cholesterol, reduce blood pressure, improve symptoms of allergic rhinitis, improve muscle strength and endurance and aid in blood sugar control. Some evidence also suggests that spirulina has anti-cancer properties.
