A. Yes, as I know you supplement your diet with vitamin C. This is reduced when you exercise extensively. And its recovery helps in muscle formation. Excessive body heat and sweat loss during the exercise can reduce the blood plasma levels of vitamin C. Have balanced diet along with plenty of fruits and vegetables. Drink 8-10 glasses or more of water every day.
