What supliment do guinea pigs need because thir boddies cant produce it?

Guinea pigs, like humans, cannot synthesize vitamin C in their bodies. This means that they must obtain this essential nutrient from their diet. Vitamin C is necessary for a variety of bodily functions, including the synthesis of collagen, the absorption of iron, and the functioning of the immune system.

Guinea pigs should be fed a diet that is rich in vitamin C. Good sources of vitamin C for guinea pigs include fresh fruits and vegetables, such as oranges, strawberries, bell peppers, and broccoli. Guinea pigs can also be given vitamin C supplements, but it is important to follow the directions on the package carefully to avoid giving them too much.
