I’m in the process of restoring an old home, and the drywallers are just finishing up. However, I did not put “green board” up in the bathrooms, and am nervous about water damage. Are there any waterproofing products out there that I would be able to apply to prevent future damage?

Source control, ventilation, and filtration are the keys to healthy indoor air quality. Dehumidification is important too.

Don't sweat it. Geenboard is overrated, and shouldn't even be on ceilings unless you strap it 12" on center. Prime the drywall well, and paint it, and you shouldn't have any problem. I've heard rumours that the greenboard line was going to be discontinued eventually anyway, but who knows.
Edit, Meant to add that I usually use a setting compound regardless what type of rock is used.

Never use it unless someone else specs it. Never had a moisture related call back. DanT
Ditto to the others - and it won't hurt to make sure the bathroom is properly ventilated. Even better if you can use one of those fan switches with a built in timer.
Greenboard is a product looking for a market. Latest building code will outlaw using GB in a wet area e.g. shower. This is coming about 25 years too late.
