Muscle building?

Alright, so Im on a new Navy SEAL workout program and all I gotta say is WOW it has challenged me to work out in a whole new way and pushed myself to my utter limits. What are good foods to consume while on this workout plan? I know protein and carbs are important but what other suppliments can I use to feed my body & build muscle? Also…any tips on building muscle and endurance? Thanx
