Have you ever sat and stared at the vibrant colors in a spring or lake? They are just beautiful, aren't they? Have you ever wondered what makes lakes and springs and other water sources their vibrant colors? Maybe you already know. It's algae. Various forms of blue-green algae. Spirulina is one such form of blue-green algae that is edible.
According to
NASA, "the Nutritional value of 1kg Spirulina is equivalent to 1000kgs of assorted fruits and vegetables." In other words, it would take a LOT of fruits and vegetables to give you what just a little bit of Spirulina does. In other words, a little goes a
long way.
Spirulina has joined the short list of "Super Foods" because of the amount of concentrated nutrients it contains. It is high in protein, vitamins, minerals, carotenoids and antioxidants. Pretty much anything that any other vegetable or fruit can lay claim to, Spirulina also claims and more. And unlike other forms of blue-green algae, (e.g chlorella) Spirulina does not have a cell membrane and is therefore more easily assimilated by our digestive system.
Mistakenly originally classified under the genus
Spirulina, the edible blue-green algae that we know and love are technically classified as
Arthrospira. Though we now know better the old misnomer has persisted in popular culture. Under a microscope, it look like this:
Spirulina occurs naturally in tropical and subtropical climates. Often found near volcanoes, it grows in alkaline lakes on every continent. It was a popular and much used food by the Aztecs. They referred to it as 'techuitltal'. One of Cortes' soldiers recorded how the Aztecs would harvest it from Lake Texcoco and sell it as cakes. Today, Spirulina is primarily harvested from either Lake Texcoco, Lake Chad in Central Africa or the Great Rift Valley in east Africa.
Spirulina has been recognized by the United Nations, NASA and the European Space Agency (MELISSA). In 1974 the U.N.'s Word Food Conference declared Spirulina "the best food for the future" and created the 'Intergovernmental Institution for the use of Micro-algae Spirulina Against Malnutrition' (
IIMSAM) to promote the use of Spirulina in the fight against hunger. Both NASA and MELISSA are looking into using Spirulina as a primary food source for long-term space missions.
Pretty crazy, huh?
You can buy Spirulina in many different forms--in flakes, powder, tablets, or pills.
Whenever I make myself a smoothie I always make sure and add powdered Spirulina. In small doses (1/4-1 tsp) you can't even taste it. Occasionally I will mix a teaspoon in some water and drink it that way. Though that is the best way to take it to assimilate all its nutrients, I don't recommend it for taste. Spirulina is a potent detoxifier so if you are taking it for the first time start out slow and than gradually increase your dose.
Here's a recipe to try:
Spirulina Superfood Smoothie
1 cup whole-milk organic yogurt
1/2 cup fresh pressed juice (I used apple)
1/2 cup frozen blueberries
1/4-1 tsp. Spirulina (Get it here.)
1 Tbs maple syrup (or sweeten to taste)
Using Spirulina is a fast and easy way to add more dense, green nutrients into your diet. Though it may seem expensive when you buy it in bulk at the store, a little goes a long way and it is worth its weight in gold.
Stay healthy and enjoy!

Do you take Spirulina? How do you incorporate it into your diet?
