Troy Vitamin C Injection is a sterile injectable solution formulated for dogs and horses. It's a veterinary-use product intended to deliver a rapid dose of ascorbic acid when supplementation through diet isn't practical or fast enough — typically during recovery, illness, or periods of physical stress. Administration should follow veterinary advice.

Vitamin C acts as an antioxidant and supports collagen synthesis, immune function, and wound healing. Because it's water-soluble, animals excrete it quickly, which is why some veterinary protocols call for injectable top-ups rather than oral dosing. The 100ml multi-dose vial is designed for clinic use, where dose volume and frequency are set by the treating vet based on the animal's weight and condition.

Owners generally encounter this product through their vet rather than picking it off a shelf. It's chosen when a measured, fast-acting dose matters — post-surgery, during recovery from illness, or in performance horses under heavy training loads.
