Spirulina is a “microscopic, spiral-shaped blue-green algae found in the sea and warm, alkaline bodies of freshwater.” Spirulina is considered a super food for your body because it contains super-concentrated sources of protein, vitamins, minerals and carotenoids.

Spirulina contains lots of essential fatty acids, and it’s an ideal food for vegetarians and vegans. It contains B vitamins including B12 and vitamins C, D and E. It also has potassium, calcium, zinc and iron. Besides being packed with vitamins and nutrients, it may also help people lose weight.

Dosage and Precautions

  • A regular dose consists of 500 mg a day; however, there is a possibility of side effects and interactions with other medications. So, be sure to speak with your doctor first before taking spirulina. In addition, talk to a doctor before giving spirulina to children.
  • Talk with a doctor first before taking spirulina if you are pregnant or nursing.
  • People with phenylketonuria (PKU) should avoid spirulina because they may not be able to metabolize the amino acid phenylalanine.
  • People who have an autoimmune disease like rheumatoid arthritis, lupus or multiple sclerosis should not consume spirulina because it may make their condition worse.
  • Be sure to buy spirulina from a reputable health food store. Spirulina–like any blue-green algae–may be contaminated with toxic substances and bacteria as well as absorb heavy metals from the water, which could have adverse side effects ¬†(University of Maryland).
