Vitamin C injection is used in dogs, cats, camels, cows, goats, sheep, pigs and horses to treat and prevent vitamin C deficiency and urinary tract infections (UTIs). Used by animals for tissue growth and maintenance, amelioration of oxidative stress, and immune regulation.

• Treatment of Scurvy: This is a primary use in animals that cannot synthesize their own Vitamin C, such as guinea pigs and some primates.
• Nutritional Supplementation: It is used as a high-quality, rapidly absorbed source of Vitamin C in various animals (cattle, horses, sheep, swine, dogs, and cats) to address deficiencies, especially in cases of liver disease or poor diet.
• Stress Relief: Injections can help mitigate the effects of stress (e.g., related to transportation in livestock or illness) by supporting adrenal function and immune response. 

• Immune System Support: It is used to boost the immune system, helping animals fight off infections or manage chronic diseases like cancer or feline immunodeficiency virus (FIV).
• Enhanced Healing and Recovery: Vitamin C is essential for collagen synthesis, which accelerates wound healing after surgery, injury, or fractures.
• Antioxidant and Anti-Inflammatory Effects: As a potent antioxidant, it neutralizes harmful free radicals, reduces oxidative stress, and provides anti-inflammatory relief for conditions like arthritis or inflammatory bowel disease.
• Treatment of Toxicities: It is used as an antioxidant to help treat certain toxicity syndromes, such as acetaminophen toxicity in cats and dogs.
• Urinary Acidification: In some cases, it can be used to help create a more acidic urine to help manage certain types of urinary stones (struvite uroliths) in dogs and cats.
