* Most animals can synthesize their own vitamin C: Their bodies produce it from glucose, so they don't need to obtain it from their diet.
* Some animals cannot synthesize vitamin C: These include primates (including humans), guinea pigs, bats, and some birds. They must obtain vitamin C from their food sources.
Therefore, the type of vitamin C needed by animals depends on their species:
* Animals that synthesize vitamin C: They don't require specific forms of vitamin C as their bodies can create it.
* Animals that cannot synthesize vitamin C: They need to consume L-ascorbic acid in their diet. This is the biologically active form of vitamin C and is readily absorbed by the body.
Here are some examples:
* Dogs and cats: They can produce their own vitamin C and do not need supplementation unless there is a specific health issue.
* Horses: They can also synthesize vitamin C, but their needs can vary depending on their workload and diet.
* Guinea pigs: They need to get vitamin C from their diet, usually through fresh fruits and vegetables.
* Humans: We need to obtain vitamin C from food sources such as fruits, vegetables, and fortified foods.
If you are unsure whether your pet needs supplemental vitamin C, it's best to consult with your veterinarian.
