Spirulina is a blue-green algae that is usually consumed either in powder form or as a supplement.Also known as a nutrient-dense food as it is packed full of vitamins, including vitamins A, C, E and B vitamins, as well as a whole host of minerals such as calcium, magnesium, zinc and selenium.In particular, vitamin C and selenium are both antioxidants and help protect our cells and tissues from damage.This algae is also an excellent vegan source of iron, providing 2mg per tablespoon (7g) which is about 23% of the Nutrient Reference Value (NRV) for men over 18 years and women over 50 years, and 13% of the NRV for women aged 19-49 years old.
Spirulina is also high in protein, with just 1 tbsp (7g) providing almost 4g of protein per serving.
