Is Vitamin C Good for Horses' Respiratory System?
In the equine world, the health of a horse's respiratory system is paramount for its overall well-being and performance. Among various nutrients essential for maintaining a healthy respiratory tract, Vitamin C stands out for its significant benefits. This blog delves into the role of Vitamin C in supporting the respiratory health of horses, backed by scientific research and expert opinions.
The Role of Vitamin C in Equine Respiratory Health
Vitamin C, or ascorbic acid, is a potent antioxidant that plays a crucial role in the body's immune response and tissue repair processes. Unlike humans, horses can synthesize Vitamin C in their liver from glucose. However, certain conditions, such as stress, illness, or age, can impair this ability, making supplementation necessary.
Supporting Lung Function and Reducing Inflammation
Horses with chronic lung diseases, such as Recurrent Airway Obstruction (RAO) or Chronic Obstructive Pulmonary Disease (COPD), often exhibit low levels of Vitamin C in their lung fluid. Supplementation has been shown to support normal lung function by reducing inflammation in the airways and improving exercise tolerance. This is particularly important as high levels of free radicals generated by exercise and exposure to pollutants can exacerbate respiratory issues.

Enhancing Immune Response
Vitamin C supports immune cells in their ability to kill pathogens and develop immunity against them. An unpublished study reported that ascorbic acid supplementation at a dose of 20 g per day increased antibody response to vaccines in aged horses, highlighting its role in enhancing the immune system's effectiveness.
Antioxidant Properties
The antioxidant properties of Vitamin C are crucial for neutralizing free radicals, which are highly reactive molecules that can damage cells and tissues, including those in the respiratory tract. By donating electrons to these free radicals, Vitamin C helps to mitigate oxidative stress and inflammation, thereby protecting the respiratory system .
Sources and Supplementation
While horses can produce Vitamin C, the amount may not always be sufficient, especially in older horses or those under stress. Fresh grass is a rich source of Vitamin C, but its levels drop off in the winter when horses are on hay. Supplementation can be beneficial in these cases to maintain adequate levels of Vitamin C and support respiratory health.

Choosing the Right Supplement
When considering supplementation, it's essential to choose a product that is specifically designed for horses and contains other beneficial ingredients such as omega-3 fatty acids, MSM, and quercetin, which are known to support lung health.
