Dr. Eric Gershwin, in his book, “Spirulina in Human Nutrition and Health,” writes that spirulina contains protein-forming amino acids. Protein, utilized by every organ and tissue in your body, powers cellular processes and is necessary for building red blood cells and repairing muscles.
Spirulina contains gamma-linolenic acid, an omega-6 essential fatty acid. Your body needs omega-6 to perform crucial functions but cannot produce it. Essential fatty acids play a role in healthy skin, hair and metabolism and may protect you from some chronic diseases, such as hypertension, and high blood pressure.
Spirulina is a source of vitamin E, B-complex vitamins and beta-carotene. B-complex vitamins are essential for many body functions, including growth and metabolism. Beta-carotene provides your body with vitamin A, a key ingredient in eye and bone development. Vitamin E helps to protect your cells from aging and improves your immune system. Spirulina contains the minerals iron, zinc, copper and selenium. Zinc is an essential mineral that boosts your immune system. Copper plays a key role in the production of red blood cells and the formation of connective tissue. Selenium helps with thyroid and heart functions. Spirulina contains chlorophyll, a type of phytonutrient, which offers antioxidant properties- protecting cells from damaging atoms called free radicals.
