Vitamin C (monophosphate)

Vitamin C  is vital to a healthy, well-functioning immune system.

Under normal conditions, horses produce enough vitamin C in their own bodies to meet their needs.

Eating green, leafy forage also tops up the horse’s vitamin C levels.

There are circumstances where supplementing with vitamin C may be recommended.

When a horse’s immune system is depressed; during periods of stress, illness, injury, and intensive exercise a horse may not be able to synthesize sufficient vitamin C to keep up with demand. During these times supplemental vitamin C can be beneficial.

The source of Vitamin C used is very important. Progressive Earth Vitamin C is in the form of Vitamin C monophosphate which is a highly absorbable form, unlike Ascorbic acid which is poorly absorbed by horses.

Benefits of Vitamin C for horses:

  • Highly-strung horses that become over-stressed by training.
  • Horses that are fed mainly Hay or Haylage.
  • Horses without access to green pastures / on poor pasture or not allowed sufficient grazing time.

  • Horses on stall confinement.
  • Unwell or stressed horses, especially those with issues affecting the immune system.
