Vitamin D is really important. There is an established causal link between vitamin D and immune function. It doesn't just enhance your immune response - it's a prerequisite for an immune response.

Anecdote: Prior to vitamin D supplementation, I caught something like 4 colds per year on average. I'm pretty sure I never did better than 2. I started taking daily D supplements about a year and half ago, and caught my first cold a few days ago. It's worth taking purely as a preventative cold medicine.
