Yes, the proper nutrition can help you recover better.

Wound healing, for example, requires good amounts of zinc, vitamin C, E & A. And probably wouldn't hurt to take a b complex too. This article also mentions the importance of having sufficient protein too.

For increasing serotonin levels vitamin b6 and niacin are really the best ways.

I also think that digestive enzymes are wonderful. If you take them on an empty stomach they have benefits like anti-inflammatory properties, and soe other things too. But taking them with your meals can help you absorb the most from your food.

Bromelain is one enzyme that most people are familiar with for dealing with inflammation. Bromelain with papain can be good with meals or on an empty stomach to help with any inflammation.

But the proper nutrition and some enzymes might be a good start.
