In short, no, it varies. Most mammals can produce their own vitamin C, for example, so they don’t need to take it in with food. Humans (and other primates from the same group as humans, and also bats and guinea pigs) can’t make their own vitamin C, and therefore require to have it in their diet. In humans it’s due to a certain mutation that have broken our vitamin-C-making gene a long, long time ago.
