NUTRITIONAL PROFILE
Amino acids
Spirulina contains between 50 and 70% protein in a highly digestible form, this is 2x higher than soya and 3x higher than meat or fish.
Spirulina is considered as a complete protein source, because it provides all of the 9 essential amino acids: Histidine, Isoleucine, Leucine, Lysine, Methionine, Phenylalanine, Threonine, Tryptophan and Valin. Essential amino acids cannot be synthesized by the body.
Spirulina also provides 9 out of 12 non essential amino acids. Alanine, Arginine, Aspartic acid, Cysteine, Glutamic acid, Glycine, Proline, Serine and Tyrosine.
Polysaccharides
Spirulina contains 10-15 % carbohydrates, primarily polysaccharides, easily absorbed by human cells with minimal intervention of insulin. Hence, Spirulina sugars provide quickly energy, while minimizing the risk of hypoglycemia. Spirulina contains specific sulfated polysaccharides, such as calcium spirulan (Ca-SP), with powerful antioxidant, antitumor and antiviral properties. Calcium spirulan, composed of rhamnose, ribose, mannose, fructose, galactose, xylose, glucose, glucuronic acid, galacturonic acid, sulfate, and calcium, was found to inhibit the replication of several enveloped viruses, including Herpes simplex virus type 1, human cytomegalovirus, measles virus, mumps virus, influenza A virus, and HIV-1.
Essential fatty-acids
Spirulina is made of only 7 % lipid, most of it in form of essential fatty acids. Spirulina is particularly rich in gamma-linolenic acid (GLA), it is the second richest source of this nutrient after maternal milk. GLA has showed positive effects on cardiovascular protection (lowering total cholesterol and LDL, raising HDL cholesterol), atopic dermatitis, immune system (increasing lymphocytes), rheumatoid arthritis and
possibly cancer treatment. Spirulina also contains sulfolipids, a class of lipids which possess a sulfur-containing functional group. Spirulina
sulfolipids, such as sulphoquinovosyl diacylglycerol (SQDG) have proved to be effective against HIV. Preparations obtained from Spirulina biomass have also been found active against herpesvirus, cytomegalovirus and influenza virus.
Minerals
Spirulina contains essential minerals and trace elements absorbed from its growth medium into chelated, easily absorbed forms:
-
Potassium : A crucial mineral that regulates body electrolyte balance. Deficiency can cause heart arrest, hypertension, adrenal exhaustion and muscular collapse.
-
Calcium : The most abundant mineral in the body, it is especially important to bone and dental health, but is also involved in neural transmissions to the muscles. Spirulina supplies about as much calcium, gram for gram, as milk.
-
Zinc : The pivot point of over thirty vital enzymatic reactions, with profound effects on mental health, skin tone, prostate function and healing capacity.
-
Magnesium : Deficiency can lead to spasmodic muscle disorders, including cardiac irregularities. Helps assimilation of vitamin C, B vitamins and protein.
-
Manganese : Activates enzyme systems, along with zinc. Promotes activity of neurotransmitter acetylcholine, and helps stabilize blood sugar.
-
Selenium : Originally believed to be a toxic heavy metal, but now known to be necessary for health. It prevents premature aging, harmful oxidation and free radical formation, reduces the toxic effect of carcinogens, and improves cardiac efficiency.
-
Iron : Promotes formation of haemoglobin, the oxygen-carrying blood pigment found in healthy red blood cells. Iron deficiency is most common among women in their reproductive years.
-
Phosphorus : The second most abundant mineral in the human body, it is found in practically every cell. Functions with calcium to maintain bone density. Helps to digest carbohydrates and the B vitamins niacin and riboflavin.
Vitamins
Spirulina supplies several of the vitamins that we need to carry on metabolic processes:
-
Provitamin A (beta-carotene) : one gram of Spirulina covers 46 % the daily requirements in vitamin A for an adult (see also below under “carotenoids”). Provitamin A is antioxidant and essential to eyesight. It protects the skin and the eyes from UV and prevent skin aging. The level of beta-carotene in spirulina is 10x higher than in carrots.
-
Vitamin B1 : for optimal functioning of our muscular and nervous system.
-
Vitamin B2 : needed for energy production.
-
Vitamin B3 : helps reducing cholesterol.
-
Vitamin B12 : Spirulina is the only non-animal source of vitamin B12. Its concentration is 4x higher than raw liver. One gram of Spirulina covers 33 % the daily requirements. Vitamin B12 fights anaemia. It is important for red blood cell creation and development. Spirulina is therefore highly recommended for vegetarian people.
-
Vitamin E : has a positive effect on the cholesterol level and prevents cardiovascular diseases.
-
Vitamin K : Increases calcium fixation, softens artery and increases blood coagulation.
-
Spirulina also provides the following vitamins : B5, B6, B7, B8, B9, and D.
Carotenoids
Carotenoids are organic pigments. They are used as precursors by our body to synthesize the appropriate vitamins. A good example is provitamin A (beta-carotene), a precursor of vitamin A. The advantage of beta-carotene is that it is converted by our body into vitamin A only when needed, thus minimizing the dangers of toxicity linked with an overdose of vitamin A (difficult to eliminate).
Enzymatic Pigments
Spirulina is also rich in pigments that are bio-chemically important. Without theses pigments, our organism would not be able to synthesize many of the enzymes necessary for the balance of our metabolism.
-
Chlorophyll: This pigment gives the green colour to spirulina. It helps human body to eliminate toxic heavy metals (mercury, arsenic, lead)
-
Phycocyanin: This pigment gives its blue colour to spirulina. It stimulates the immune system, and has antioxidant as well as anti-inflammatory effects. Spirulina is the only source of phycocyanin in the world.
-
Porphyrin: a red compound that forms the active nucleus of hemoglobin.
Enzymes
Besides enzymatic pigments, Spirulina contains many other enzymes. It is particularly rich in superoxide dismutase (SOD), a powerful antioxidant.
