Spirulina platensis is a blue-green algae that is rich in antioxidants, fatty acids, vitamins, minerals, and essential amino acids. Feeding spirulina supports healthy skin, metabolism, lung function and the immune system in horses.
It is especially high in vitamin A and vitamin E which are important anti-oxidants that neutralize free radicals in all cells of the body. Horses fed hay-based diets may be deficient in several vitamins and could benefit from the abundant vitamins and minerals found in spirulina.
This supplement is a source of the fatty acid gamma linolenic acid (GLA) . GLA is an anti-inflammatory omega-6 fatty acid. It has been shown to promote support wound healing and tissue repair in humans and exhibits anti-bacterial and anti-viral effects. [1]
Spirulina powder is especially high in protein (up to 70%) and is considered a complete protein. This equine supplement might be beneficial for young animals and heavily exercised horses to support their high protein needs. Although it provides all essential amino acids, it is considered low in lysine and methionine.
