Hi Sam,

I found some papers that deal with this subject. Maybe it can help you.

I hope this helps.

Hello Sam,

Here are a few resources for you to review that deal with nutrition and recovery specifically for elite athletes. The first organization is a leader for research on supplements, nutrition and recovery for athletes. I have worked with their members on NFL athlete related projects. Their website has links to research and resources http://www.sportsrd.org

Also a seminar and corresponding slides http://www.humankinetics.com/all-webinars/all-webinars/culinary-recovery-practical-solutions-to-feed-success

On vitamin D here's some information as it relates to athletes 

Vit. D can block the action of enzyme which is needed to make the "stress hormone" cortisol http://ow.ly/U6jIb
