If he's getting five minutes or more of sunlight per day, he's probably getting what he needs to be healthy. Being outside is actually the best solution of all. Windows won't do it -- they block the UV light that they need to process Vitamin D. YOu need sunlight that has not passed through glass.
There are some good UV-producing bulbs on the market, but they are expensive and need to be replaced every 6 months. A protected fixture right above the cage would be a good way to mount one, but make sure it is a true full spectrum bulb, many bulbs marketed as such are merely daylight balanced. To produce UV they need a special coating and it wears off quickly. Avian Sun is one brand that does produce measurable UV-A and UV-B light. Birds also see into the UV part of the spectrum, so being under normal bulbs does color-shift their world a bit!
