Benefits of Vitamin C for Horses

Vitamin C is a vital organic compound within a horse’s body that provides protection against cellular damage. It aids in equine collagen production, iron absorption, hormone synthesis, bone calcification, tissue growth & wound healing whilst simultaneously reducing allergy symptoms and inflammation by counteracting the production of histamines. Additionally, Vitamin C is a powerful antioxidant which neutralises free radicals and acts to strengthen equine immune function and response.

Unlike humans, horses can synthesize their own Vitamin C from glucose in their livers – however deficiency can arise during period of stress or illness. A lack of Vitamin C can lead to several health problems in horses, including poor wound healing, reduced immunity, and joint pain.

Sodium ascorbate is a more bioavailable form of Vitamin C, meaning that the body more easily absorbs it. As a result, supplementing with sodium ascorbate can help to ensure that horses get the Vitamin C they need to stay healthy.

Immune System

Vitamin C is a natural immune system booster. It helps increase the number of antibodies in your horse’s body responsible for fighting toxins, bacteria, or viruses.


Vitamin C helps the production of collagen, a vital tissue that promotes joint and bone health.


Vitamin C boosts your Horse’s level of interferon, a natural antibody that helps fight viral infections and cancerous growths.


Supplementing Vitamin C has been linked to helping the absorption rate of other nutrients in the diet (or supplement).


Vitamin C is a vital antioxidant for horses. They need it to maintain a healthy, lustrous coat. It usually combines with Vitamin E for them to look vibrant.


Vitamin C helps relieve allergy symptoms because it acts as an antihistamine, a compound that counteracts histamine and fights inflammation.

Why Sodium Ascorbate?

Sodium Ascorbate vs Ascorbic Acid

CEN Vitamin C uses Sodium Ascorbate which is a highly effective, more easily absorbed form of Vitamin C. It is pH neutral (pH 7.4) as opposed to acidic Ascorbic Acid (pH 3.0), therefore Sodium Ascorbate does not irritate the intestinal tract or kidneys. Sodium ascorbate is easily absorbed by the body, and studies have also shown that it stays in the system twice as long as the acid form. Sodium ascorbate is the only form of vitamin C approved by the FDA for intravenous injection in humans.


Vitamin C (as Sodium Ascorbate)


How much Vitamin C to give a horse?

In general, horses can be supplemented with Vitamin C at a feed rate of ~ 3-5g/day (3000mg – 5000mg) this amount may need to increase for hoses over the age of 20 or for horses needing more intensive supplementation. The National Research Council suggests the safe upper limit of 22000mg/ day (~22g)

Do horses need Vitamin C?

A horse can make their own Vitamin C, but in times of stress on the gut microbiome, this production can be lowered and supplementation maybe required. It is recommended to add a source of Vitamin C when a horse is:

  • A Competition Horses e.g Endurance, Eventers and Racehorses
  • Post-Operative Or Post-Trauma
  • Suffering from Wounds, Infections or Diseases
  • Suffering From Inflammatory Conditions
  • Suffering Heaves or Allergies
  • An Aged Horses with Chronic Infections or Decreased Immunity
What does Vitamin C do for horses?

Vitamin C is also a powerful antioxidant that helps protect from cellular damage. Vitamin C plays several important roles in horses’ bodies, including:

  • Supporting the immune system
  • Collagen production
  • Recovery after training/performance
Can horses take HUMAN Vitamin C?

Vitamin C can be present in a number of different forms. Sodium ascorbate is a less acidic form of Vitamin C when compared to Ascorbic acid which is commonly used in human varieties of Vitamin C. Human grade ingredients are generally better-quality and suitable for horses.

    I will be adding CEN VIT C to my horses diet during times of stress, another simple yet effect way to improve their nutritional profile – thanks CEN!

    Most underrated product! The difference in my horses head shaking behaviours have minimised dramatically, their immunity is incredible after a hard winter and their coats look amazing especially after we have had ticks and mosquitos buzzing around. A fantastic addition to any diet to ensure a horse is as healthy as can be!
