Plant Pigments and the Equine Immune System

Green drinks are a hot human health craze these days with good reason. But did you know brightly colored foods are as healthy for your horse as they are for you?

Plant polyphenols are natural compounds with strong antioxidant capacity, with plant pigments having a variety of benefits for the immune system. Green pigment (chlorophyll) is only a piece of the picture. Flavonoids, carotenes, lycopene, zeaxanthin, anthocyanins and betalains are also plant pigments that provide amazing benefits for immune function.

Antioxidant Phenolic compounds are widely distributed through nature in herbs. These Phenolics are some of the most potent antioxidants ever found, and penetrate into body tissues easily. It has also been confirmed that combinations of different plant Phenolics and Bioflavonoids work together to produce a greater effect, meaning that lower dosages can be used.

Immunity is an amazing and complicated function. It is divided broadly into two reactions that shoot first, and ask questions later. The innate immune system responds immediately to any foreign substance or organism. The sophisticated immune system targets specific invaders with antibodies and remembers them in stored cells.

Healthy inflammation is a built-in immune response to invading organisms or toxins, as well as the method of removing dead or injured tissues. The immune system also has an intricate set of checks and balances that protects the body’s own tissues from direct attack as well as from collateral damage from friendly fire. 

Many plant flavonoids also work with the body’s defense systems in fortifying defense systems against the invasion of cells by harmful organisms.

  • Chlorophyllin, a derivative of chlorophyll, supports the natural healing of open wounds and its consumption is associated with higher numbers of all immune system cells. Chlorophyll and chlorophyllin are also natural antioxidants, as are all plant pigments.
  • Bioflavonoids are a diverse class of plant chemicals with well documented antioxidant effects and include Hesperidin, Quercitrin, Rutin and Tangeritin, which can help preserve Vitamin C levels in the tissues. Some Citrus Bioflavonoids can also stabilize capillary walls, help prevent swelling at areas of allergic reaction, and help maintain normal, healthy levels of inflammation.
  • The skin and seeds of grapes are rich in polyphenol, with the most well known being Resveratrol. Grape polyphenols also have directly support a population of T cells that contribute to targeted immune responses. They also have the capacity to balance inflammatory reactions.
  • The pigments of the blue-green algae Spirulina work with the horse’s body in the same way, and also helps stabilize the mast cells that release histamine.

Vitamins are also known to be supportive of healthy immune function.

  • Vitamin C is an important antioxidant in the immune system that protects the interior of the cells. It has been clearly shown that Vitamin C levels in lung fluid from horses with chronic lung disease are low.
  • Vitamins A and E are fat soluble antioxidant vitamins which work protecting the cell membrane from attack. Vitamin A, from Beta-Carotene, is particularly important for skin.
  • The B vitamins support active division of immune system cells and some have specific immune system functions. Riboflavin is involved with both the destruction of organisms by immune cells and in cellular immunity. Thiamine is also essential to normal functioning of T cells in the cellular immune system. Folic acid deficiency has been clearly linked to increased infection risk.
