What Is Spirulina—and How Do I Use It?

What Is Spirulina—and How Do I Use It?

Before you buy your own spirulina powder, let us explain why we love it, how you should try it, and why it's here to stay.

You probably never thought you would be adding algae powder from tropical lakes to your smoothies, but spirulina is becoming quite the popular addition for many health-focused eaters. Even though this superfood is in the spotlight right now because of its nutrients, bright green color, and bounty of healthy benefits, spirulina has been a superfood long before 21st-century nutritionists began adding it to their smoothie bowls.

Spirulina is quite possibly one of the oldest life forms on Earth. The first people to ever use this algae as a food source is unclear, but Aztecs and African natives may have consumed the algae in their daily diet many centuries ago.

Eating healthy should still be delicious.

Fast forward to today, we understand why spirulina is here to stay. Our assistant nutrition editor, Jamie Vespa, MS, RD, breaks down why this superfood clearly has staying power and is gaining momentum in superfood circles:

Dried spirulina contains about 60 to 70 percent protein. It’s actually considered one of the few plant-based sources of “complete protein,” meaning it contains all essential amino acids your body needs but can't produce on its own. It’s also a good source of calcium, iron, magnesium, and vitamins A, E, and K. Spirulina may be more beneficial for vegans or vegetarians that lack adequate iron in their diet. Touted as a “superfood," health claims surrounding the blue-green algae include its ability to boost immunity, fight allergies, and reduce fatigue.

With its high nutrient density, the benefits of spirulina reach far and wide. We love it in our smoothies in the morning because research suggestions the powder may boost energy, reduce fatigue, and naturally suppress appetite. Great benefits, right? That's why we say it's time to say goodbye to coffee and hello to spirulina smoothies.

Like other superfoods, spirulina may strengthen the immune system, help with digestion, balance the body's pH, and reduce inflammation. Small studies support these claims, but more research is needed to know if these claims are true.

Spirulina is available as tablets or powders. We prefer the algae in its powdered form because it's easy to add to recipes, such as our Best Green Smoothies. However, "spirulina can get a bit pricey, and it's always important to remember the lack of quality control in the supplement industry. As such, do your research to find a quality product that has been third-party tested and is certified free of contamination," Vespa explains.

Cooking With Spirulina: The Dos And Don’ts

Spirulina has been a culinary ingredient for centuries. Spanish colonists came across the Aztecs harvesting and using it while exploring Mexico. The Kanembou people in Chad are believed to have been using it all the way back in the 9th century. These days, spirulina is seen as more of a nutritional supplement in the United States but it is still viewed as a food in some parts of the world. Like any food item that has been around for a long time, there are rules regarding its use. Let’s break down the dos and don’ts of cooking with spirulina.

The two ingredients we use in our wellness shot recipe are oranges and spirulina powder, these two ingredients are readily available to buy in most big supermarkets. Unless you can’t find organic spirulina powder in your local supermarket, you will definitely find it in health and wellbeing stores. Spirulina has lots of health benefits containing all of the amino acids that are crucial for our bodies to function well. It is also packed with vitamins, minerals, and active compounds with positive effects on our health and wellbeing.

With only two ingredients to make this shot, it is very easy to make but try adding a little bit of lemon juice, lime juice, or a little bit of grated ginger you can put your own twist on it very easily.

Both spirulina and oranges are alkaline ingredients. Even though oranges are high in citric acid they are part of a food group that will alkalize our body. This is because when we metabolize or convert our food into energy there is a chemical reaction that leaves behind metabolic waste and this waste is either acidic, alkaline, or neutral. When the residue or ash is left behind whatever its Ph level is will affect our body’s acidity. The thought is that the more acidic you are the more susceptible you are to illness and disease. The more alkaline you are the more protected you are to potentially lower the risk of cancers and other acute illnesses.

Sprirulina and chlorella are powerful detoxifier so it is important to start with a small dose and work your way up so that you can see how your body responds, and then gradually increase your dosage. Some detoxification reactions that can possibly occur when consuming these algae are: a low-grade fever, dark green waste, excessive gas, restlessness, breaks out or itchy skin, and or sleepiness.

These symptoms are temporary and are evidence that your body is responding to it. If you are pregnant, nursing or have hyperthyroidism you should discuss supplements with your health care provider.
