What is Spirulina?
If you’re looking for a plant that can nourish your body by providing most of its protein requirements, can prevent allergies and reinforce your immune system, then spirulina is what you need.
Spirulina is a natural algae (cyanobacteria) that are incredibly high in protein and nutrients. It is obtained primarily from two species of cyanobacteria: Arthrospira platensis and Arthrospira maxima. Unlike other plants that grow in the soil, Spirulina grows in the form of blue-green algae in both fresh water and salt water in the wild. It is also commercially cultivated in Spirulina farms. The name originates from the Latin word for ‘helix’, or ‘spiral’, because of its spring like physical characteristics.
This plant is consumed as food as well as a dietary supplement. It’s available in tablet, powder and flake form. Besides being consumed by humans, it is also used as a feed supplement in aquaculture, aquarium and poultry industries. Spirulina is largely composed of proteins and amino acids and hence, is beneficial for vegetarians. The high content of protein and iron makes it beneficial during pregnancy, after surgery, and for boosting the immune system. Since it is a concentrated whole food, it is easily incorporated in various dishes, particularly for children who do not like vegetables.

- Vitamins: B-vitamins refer to a group of water soluble vitamins that are required for energy production as well as formation of red blood cells. Spirulina is a good source of B-vitamins and it contains an exceptionally high amount of vitamin B-12. It also contains vitamin B1 (thiamine), B2 (riboflavin), B3 (nicotinamide), B6 (pyridoxine) and B9 (folic acid). Other vitamins found in these algae include Vitamin, K, vitamin C, vitamin D, vitamin E and Vitamin A. The level of vitamin E in Spirulina is comparable to that of wheat germ and it possesses 4 times as much vitamin B12 as raw lever.
- Protein: Spirulina comprises of at least 60% protein. A 112 gram serving provides approximately 64 grams of protein. 83% to 90% of this is digestible because, unlike yeast and chlorella, these algae do not have cellulose walls. It has a high net protein utilization ratio (NPU) of 53% to 61%. The high protein efficiency ratio (PER) of Spirulina indicates that your body is efficiently able to use the amino acids. Protein makes up 15% of the body’s weight and is a vital nutrient for healthy growth.
- Beta-Carotene: Beta-carotene is a pigment belonging to the carotenoid family and is widely known for its antioxidant properties. It is mostly found in fruits and vegetables, imparting red, orange or yellow color to them. A half cup of dried Spirulina provides about 342 mg of beta carotene.
- Essential Fatty Acids: Essential fatty acids are also known as good fats. Since these fats are not produced within the body, they have to be provided from the food sources that contain them. Their main function is to produce prostaglandins that control the body functions like heart rate, blood pressure, fertility and immune system function. Spirulina contains 4% to 7% essential fatty acids such as gamma-linolenic acid (GLA), alpha-linolenic acid (ALA), linolenic acid (LA), stearidonic acid (SDA), eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA) and arachidonic acid (AA).
- Minerals: Spirulina is rich in minerals required for the body’s daily activities. These minerals are calcium, potassium, zinc, magnesium, manganese, selenium, iron and phosphorus. They aid in metabolism, maintain water balance and improve bone health. Its calcium, phosphorus and magnesium content are similar to that of milk.
- Carbohydrates: Spirulina has only 15% to 20% of carbohydrate content. It also contains 18 different amino acids.
