I don't want to unnecessarily put a damper on things but I would like to suggest you take the word "supplement" literally - you should aim to supplement good nutrition, not somehow compensate for poor nutrition by taking supplements. The one should be in place before even considering the other.
The only times I might consider adding to good nutrition (apart from chronic dietary deficiencies, like B12 for a vegan) would be cases of extreme load. Possibly in connection with a lot of weightlifting or with heavy running sessions. For example, a protein shake or simply a chocolate milk after a hard session is a good idea.
