Regular food is fine - I haven't found an ingestible magic bullet that works any better than sufficient liquids and a decent meal.

What has made a *much* bigger difference for me is stretching and foam roller sessions following rides (when necessary/really stepping up my CTL). If I'm getting to the point where my legs ache, they'll often keep me from getting good sleep and that's the worst enemy of recovery. Stretching/rolling makes an immediate difference. That, and don't be afraid to do actual recovery rides (followed by stretching and rolling) when you're sore - I find that helps more than taking the day off.
