Spirulina is a nutrient dense blue-green algae that grows in both fresh and salt water.
For its small size it is packed full of nutrients such as protein, vitamin B1, B2, B3, copper, iron, magnesium, and many other trace minerals. Compared to many other plant sources it has some of the highest nutrient concentration per gram.
Its blue-green coloring comes from a pigment-protein complex called phycocyanin. Phycocyanin has antioxidant and anti-inflammation properties that can support cellular oxidative stress and damage. This can be beneficial for endurance where exercise induced stress can be a big contributor to muscular fatigue. Consuming spirulina may promote increased endurance and reduced time to fatigue.
Spirulina also seems to have a positive effect on blood lipids. Some studies have shown lower triglycerides, reduced lipid peroxidation, and reduced blood pressure through the stimulation of nitric oxide.
With additional research indicating immune support and eye health its easy to see why you may want to include some of this small cyanobacteria in your diet.
