Spirulina is one of several forms of blue-green algae. These macroalgae are similar to seaweed and are found on the ocean floor, in soil and on rocks and plants. Spirulina also contains the entire spectrum of carotenoids. These carotenoids work together throughout the body to increase the effectiveness of antioxidants. Spirulina also contains polysaccharides, sulfolipides, glycolipids and fatty acids. There is little scientific evidence to back up spirulina's effectiveness for the many uses it is said to have.
Protein Rich
Spirulina is made up of 60 to 70 percent protein, making it good for vegetarians and vegans to include in their diets. Plant proteins are easy to digest and do not contain cholesterol or fats, like animal sources do. Because it is a plant protein, it is easier to digest and assimilated faster than other forms of protein. It also contains the entire spectrum of essential amino acids, according to Prescription for Nutritional Healing.
Iron Rich
Spirulina is very rich in iron and other minerals. As a natural source of iron, it is more easily absorbed by the body than iron that comes in supplement form. Iron deficiency, or anemia, is very common among women as a result of excessive bleeding during periods. Internal bleeding from stomach ulcers and lesions can also result in iron deficiency.
Many women take iron supplements to make up for the iron lost during their monthly periods. Spirulina provides not only iron, but magnesium and other minerals that the body needs to remain healthy, according to Vitamin Stuff.
B12
Spirulina contains more B12 than other herbs. It also has abundant amounts of other vitamins that make up the B complex chain. Because of the high levels of B vitamins, spirulina is effective in boosting the immune system and fighting off disease and infection. The vitamins and minerals in spirulina work together to increase the production of interferon and interleuken, components that fight disease, according to Drugs.com.
There are many claims that spirulina has anti-cancer properties, as well as a variety of other qualities, but little research has been done in the way of testing for specific diseases. Before using spirulina as an alternative therapy, a physician should be consulted.
Beta Carotene
Spirulina has approximately 10 times more beta carotene than carrots. Because these carotenoids are in their most natural form, the body can break them down easily and assimilate most of the nutrients that spirulina provides.
This allows the body systems to function more efficiently with less stress. Beta carotene is an important component to healthy vision and increased immunities. It also slows down the aging process and aids in the rejuvenation of tissue. Beta carotene is necessary for healthy skin and plays an integral part in how quickly wounds and lesions heal, according to Prescription for Nutritional Healing.
