Complan Original - It's great straight, but you can make it almost any flavour you like. If you lead a busy active life, there are lots of reasons why you might need the nourishment Complan can give you. You might not have time to eat a normal meal, you could just be suffering an afternoon energy low, or you might want something light but satisfying before you go to the gym. Complan can also provide the nourishment you need when you are off colour or recuperating from illness.
