Mad Barn’s bulk Spirulina powder provides a concentrated form of blue-green algae to support your horse’s immune function and nutritional needs.
Spirulina is commonly referred to as an algae, but it is actually a naturally occurring bacteria that grows in saltwater and freshwater worldwide. Spirulina powder consists of two cyanobacterial species named Arthrospira platensis and Arthrospira maxima.
Spirulina is a nutritionally dense supplement that is easily digested. It is an excellent source of vitamins and minerals to support overall health and well-being of 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 mostly 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 rich source of the fatty acid gamma linolenic acid (GLA) . GLA is an anti-inflammatory omega-6 fatty acid. It has been shown to promote health benefits in humans including wound healing and tissue repair as well as exhibiting anti-bacterial and anti-viral effects.

This equine supplement might be particularly 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.
