Blue Spirulina Benefits

The most common variety of blue spirulina, Spirulina maxima, is native to the salt lakes of the Mexican plains, such as the Totalcingo and the Texcoco lakes. In their waters are high concentrations of sodium bicarbonate and other potassium and magnesium salts and minerals such as selenium, which avoid the pollution of the water.

An extensive net of water channels has been recently discovered around these Mexican lakes, intended for growing blue spirulina, and built by the Aztecs more than 500 years ago. These people, the Aztecs, following popular wisdom, used spirulina long before it could be watched and identified through the microscope, and modern chemistry found out its exceptional composition.

Healing Properties and Indications

Due to its nutritional richness, the composition of this water vegetable has been the focus of some outstanding research projects for the last few years. Besides chlorophyll, like all algae, blue spirulina contains:

  1. Protein. It is one of the richest natural protein sources (up to 70 percent of its weight, while soya has 35 percent, and meat 20 percent). The spirulina protein is complete and has excellent biological value. Besides the other non-essential amino acids, they contain all eight essential amino acids (those our bodies cannot synthesize) in an optimum proportion.
  2. Lipids (fats: 8 percent of its weight), mainly unsaturated fatty acids such as linoleic, linolenic, and especially gamma-linolenic acids. Blue spirulina is one of the wealthiest vegetables regarding these important substances of great value for treating arteriosclerosis.
  3. Sugars or carbohydrates (18 percent) are a rare natural sugar: rhamnose, which promotes glucose metabolism and has a favorable effect on diabetes.
  4. Vitamins A, B group, E, and H (biotin). Its content of vitamin B12 is outstanding and exceeds even that of the mammal’s liver, which makes blue spirulina a most appreciated food for people following a strict vegan diet, that is to say, lacking even eggs, milk, and dairy products. Actually, vitamin B12 is not contained in the true algae but in a type of bacteria that usually accompanies it.
  5. Several minerals and trace elements. Spirulina is especially rich in iron: 5.3 mg per 100 g of edible product (meat contains from two to three mg per 100 g, and liver 11 mg).

Due to blue spirulina’s excellent nutritional value, it has very favorable effects in many conditions and illnesses such as:

spirulina dosage for weight loss
Blue spirulina is a good nutritional compliment for elderly people, and for those suffering from malnutrition, anemia, or exhaustion, due to the high amounts of proteins, vitamins, and minerals it contains.
  1. Diets for losing weight. Due to its relatively small amount of calories (360 calories per 100 g) compared with its protein and vitamin apportion. Its use helps keep a nutritional balance in hypocaloric diets, not provoking weakness or tiredness caused by dietary deficiencies. Besides, its contents of phenylalanine, an essential amino acid present in relatively high amounts in spirulina, help, according to some researchers, reduce the sensation of hunger.
  2. Diseases that require a strict diet, such as diabetes, hepatitis, or pancreatitis, in which there exists the risk of nutritional deficiencies.
  3. Anemia. Due to its high amount of iron and essential amino acids, it promotes hemoglobin synthesis, the vital part of red blood cells. It is recommended during pregnancy.
  4. Malnutrition, recovery, and physical weakness. It acts in revitalizing and general refreshing of the body.
  5. Arteriosclerosis and its disorders: Angina pectoris, heart attack, lack of blood flow, mainly affecting the legs. The favorable action of blue spirulina is due to its content of unsaturated fatty acids, such as linoleic and gamma-linolenic acids.

Obtaining Spirulina

When straining the water of the lakes where this alga grows, and after pulverizing and desiccating it at a 158°F (70°C) temperature, the most usually consumed form is obtained, from which the capsules and other preparations are made.

The Aztecs and other peoples living close to the lakes where spirulina grows obtained it traditionally employing sun desiccation.
