What is spirulina algae?

Spirulina is a blue-green microalgae. Its botanical name is Arthrospira platensis and it is considered "green" because it contains chlorophyll and "blue" because it contains phycocyanin. Spirulina comes in tiny microscopic filaments and its name comes from the Latin "Spiral". Spirulina has been present on earth for over 3 billion years: blue-green algae are thought to have created our atmosphere, allowing life to evolve. It is incredibly rich in proteins and nutrients : it is not for nothing that spirulina falls into the category of "superfoods", being one of the most powerful sources of nutrients we have available. Spirulina algae has in fact been used since ancient times and was already known to the Aztec people as "food of the gods" . The rediscovery of this incredible microalga and the interest of the scientific community in it began about 40 years ago. NASA has even incorporated this microalgae into space programs to feed astronauts, purify the air and transform waste!

Additionally, the same amount contains only 20 calories and 1.7 grams of digestible carbohydrates. Gram for gram, spirulina may be the most nutritious food on the planet!

Spirulina algae has powerful antioxidant and anti-inflammatory properties

Oxidative damage can damage DNA and cells, generating a state of chronic inflammation that contributes to cancer and other diseases. Spirulina is a fantastic source of antioxidants , which may protect against oxidative damage. Its main active component is called phycocyanin . This antioxidant substance also gives spirulina its unique blue-green color!

How to use spirulina algae?

Spirulina algae can reduce blood pressure

High blood pressure is a major factor in many serious illnesses, including heart attacks, strokes, and chronic kidney disease. Although 1 gram of spirulina is ineffective, a dose of 4.5 grams per day has been shown to reduce blood pressure in individuals with normal levels. This reduction is thought to be driven by increased production of nitric oxide, a signaling molecule that helps blood vessels relax and dilate.

Spirulina algae can improve muscle strength and endurance

Exercise-induced oxidative damage is a major contributor to muscle fatigue. Some plant foods have antioxidant properties that can help athletes and physically active people minimize this damage. Spirulina brings great benefits in this sense, since some studies have indicated an improvement in strength and muscular endurance generated by the consumption of this food.

Spirulina algae improves the symptoms of allergic rhinitis

Allergic rhinitis is characterized by inflammation of the nasal passages. It is triggered by environmental allergens, such as pollen, animal dander or even grain dust. Spirulina is a popular alternative treatment for allergic rhinitis symptoms and there is evidence that it may be effective. In a study of 127 people with allergic rhinitis, 2 grams per day dramatically reduced symptoms such as nasal discharge, sneezing, nasal congestion and itching.
