13 Impressive Benefits of Spirulina

Spirulina offers many health benefits, some of which include lowering cholesterol levels, enhancing immunity, increasing red blood cell count, providing anti-cancerous properties and anti-inflammatory properties, protecting the liver, reducing the toxicity in the kidneys, controlling bronchial asthma, and enhancing the supply of antioxidants.

Spirulina is blue-green algae with a perfect spiral shape. This spiral shape is the reason for the name Spirulina. It belongs to a cyanobacteria species and it is scientifically known as Arthrospira platensis. Other subspecies include Spirulina maxima and Spirulina geitleri. It is generally found in alkaline lakes in Mexico and Africa. It is rich in nutrients, such as proteins, carbohydrates, vitamins, minerals, and trace elements. It has the capability of surviving in the harshest conditions, both environmentally and chemically. It can survive extreme alkaline conditions, highly saline waters containing 30 grams to 270 grams of salt per liter and still survive.

History of Spirulina

Spirulina is believed to be a photosynthetic species that is about 3.5 billion years old. It is also speculated that such species were responsible for releasing oxygen into the atmosphere on the early Earth.

This amazing food first came to light in the 1940s in French Equatorial Africa, when French troops stumbled upon a food that the locals were growing. It was growing on the surface of lakes and it was being collected, sun-dried and sold in the local markets. Biologists concluded that it was an algae that was being grown and eaten. It is also the food of local birds, like flamingoes.

Spirulina geiteleri was discovered in the alkaline lakes in Mexico and it was also being consumed by the locals. Historical writings revealed that it was consumed as food even during the time of the Spanish conquest during the 15th century. Even Columbus’ personal literature revealed something about an ooze-like substance being collected from lakes, sun-dried and baked like bread.

Nutritional Value of Spirulina

According to the National Nutrient Database for Standard Reference, the nutrients found in spirulina per 100 grams include 290 kcal of energy, 57 grams of protein, 7 grams of fat, 24 grams of carbohydrates, 3 grams of dietary fiber and 3 grams of sugar. Minerals and trace elements found in it include 120 mg of calcium, 28 mg of iron, 195 mg of magnesium, 118 mg of phosphorus, 1363 mg of potassium, 1048 mg of sodium, and 2 mg of zinc.

The vitamins found within spirulina include thiamin, riboflavin, niacin, folate, vitamin B6, C, A, E, and vitamin K.

It is widely regarded as one of the highest sources of protein. It contains around 18 out of the 22 amino acids that the human body needs. It is also a good source of vital micronutrients, such as beta-carotene in vitamin A, and minerals such as zinc, calcium, magnesium, iron, and phosphorus.

Easily Digestible: Closer examination of spirulina revealed that this spiral-shaped blue green algae had thinner cell walls or cellulose compared to its plant cousins. Also, the cell wall is composed of mucopolysaccharides, which are complex sugars. Thus, even the cell wall in spirulina can be digested, unlike the cellulose in plants. It is also beneficial for probiotic bacteria, such as lactobacillus, which live inside our digestive system.

Lowers Cholesterol Levels: Spirulina is helpful in reducing serum cholesterol levels and elevates HDL (high density lipoprotein), or “good”, cholesterol levels. The presence of gamma-linolenic acid in spirulina accelerates serum cholesterol reduction.

Protection Against Mercury Poisoning: Mercury poisoning is a concern for most animals, including man. Inorganic mercury concentrations are found mostly in kidneys and they are the worst affected organs. Studies have shown that spirulina significantly reduces the levels of mercury chloride-associated toxicity and renal damages caused by toxicity in mice.

Immunomodulatory Properties: Various studies on spirulina have revealed its immunomodulatory properties. These immunomodulatory properties include bone marrow reproduction, thymus, and spleen growth, increased white blood cell production, and an increase in the number of lymphocytes.

Increase in Red Blood Cell Count: Apart from improving the immune system, spirulina can also be effective in improving the red blood cell count. A study conducted on senior citizens revealed that after 12 weeks of taking spirulina, their red blood cell count and hemoglobin levels increased significantly.

Antimicrobial Properties: Spirulina extracts have antimicrobial properties. The extracts from spirulina have been successfully tested against viruses that affect both humans and monkeys. Viruses such as the herpes simplex virus, influenza virus, measles virus, mumps virus, human cytomegalovirus, and finally HIV-1 viruses were controlled to a major extent. Now, spirulina extracts are being considered as medicine for HIV positive patients so that they can live a longer life.

Control of Cancer: Spirulina is the richest plant source for beta-carotene and phycocyanin. These biochemicals possess anti-cancerous properties. Researchers believe that phycocyanin can scavenge the DNA-damaging toxins like peroxynitrite and can help in controlling cancer cells. It also has a role to play in significantly controlling liver cancer.

Anti-Inflammatory Properties: Having spirulina on a regular basis reduces inflammation. Recent scientific studies indicate this fact. When arthritic lab rats were given spirulina, arthritis-associated inflammation was reduced to a significant level in comparison to other controlled animals.

Protection of Liver: The biliprotein phycocyanin present in spirulina possesses liver protection properties. Research showed that the effects on the liver, when pre-treated with hepatotoxic chemicals such as carbon tetrachloride, were reduced to a significant extent. This study showed that spirulina helps in protecting liver cells from toxin damage.

spirulinainfoReduces Kidney Toxicity in Chemotherapy: While undergoing treatment for cancer, physicians may suggest chemotherapy. Cisplatin is a chemotherapeutic agent used in chemotherapy that can cause toxins to pile up in kidneys. The intake of spirulina reduces the side effects caused by cisplatin.

Reduces Ischemia: Research shows that spirulina helps in reducing ischemia, a condition wherein the blood supply to the tissues gets restricted.

Controls Bronchial Asthma: Spirulina is also beneficial for the control of bronchial asthma. Studies have shown that administering spirulina extracts at 1 gram per day can have almost an equal effect on bronchial asthma as medication does. This is true in the case of mild and moderate asthma.

Supply of Antioxidants: Spirulina is a good source of antioxidants such as phycocyanin, which helps in the inhibition of COX2, hydroxyl, peroxyl, and free radicals.

Caution

Nutrient supplements like spirulina may interact with medications, so they should be taken only after discussing it with your doctor.

It can sometimes be contaminated with heavy metals that can be toxic. Hence, buying it from a licensed and reputed manufacturer is advised.

Phenylketonuria is a metabolic condition where the amino acid phenylalanine cannot be metabolized. Such people must avoid taking spirulina, as it is rich in this amino acid.

Avoid giving it to children without medical advice. Consult your doctor to determine whether or not it is safe to give spirulina to your children, or to have it yourself.
