Spirulina is a micro-algae scientifically known by the name of Arthrospira (Arthrospira platensis and Arthrospira maxima). It lives in clear water in sub-tropical areas. It has a blue-green colour and a spiral shape, which is the origin of its name, spirulina.

Since ancient times, these algae has been used as food source and the many benefits of spirulina were well known among many different civilizations. They grew in Lake Chad, and can be traced back to the Aztec era. Spirulina used to be mixed in the bread and buns eaten by the people of Central and Western Europe for a long time.

But let’s find out something more about the health benefits and ways to use this algae.

What’s spirulina and why it can benefit you

Like all algae, it has many nutritional benefits making it a perfect addition to your diet. One of the peculiarities of spirulina is that it is rich in biliproteine. This protein is generated during digestion of the algae and in this form is easily assimilated by the body.

Other vitamins to be found in spirulina include: beta-carotene, which is good for the eyes, B vitamins, which protect the nervous system, heart and bones, vitamin D, which protects the immune system and strengthens bones, vitamin E which is an antioxidant and good for our immune system and vitamin K which fights osteoporosis, celiac disease and Crohn’s disease.
Actually, the only vitamin it doesn’t contain is vitamin C.

It should be said that the amount of vitamins it has is quantitatively comparable to those present in milk and meat.

Spirulina also contains calcium spirulan, which seems to have anticancer and antiviral properties. It has been used as a cure for children with cancer and for victims of the Chernobyl nuclear accident. Scientists, however, have still not come to any firm conclusions about its curative properties. In Belarus an experiment was conducted to determine the ability of spirulina to fight nuclear radiation. Scientists found indices of reduced radioactivity in urine following administration of this alga for about 20 days.

Other research has shown that spirulina, in particular its aqueous extract, may decrease or even prevent the recurrence of the virus HIV-1. However, this research is very news and a result of few studies that have not yet arrived at a conclusion shared by the entire scientific community.

Top 10 benefits of spirulina

While individual responses to this substance can vary, some commonly reported benefits of spirulina include:

  • Detoxification: It has been proposed to have detoxifying effects, helping to eliminate heavy metals and toxins from the body. However, more research is needed to fully understand this aspect.
  • Cholesterol Management: Some studies have suggested that it may help lower LDL cholesterol levels and increase HDL cholesterol levels, contributing to heart health.
  • Blood Sugar Regulation: There is evidence to suggest that it may have a positive impact on blood sugar levels, potentially benefiting individuals with diabetes or those at risk of developing diabetes.
  • Weight Management: It may contribute to weight management by promoting a feeling of fullness and potentially influencing metabolic processes. However, more research is needed in this area.
