There has been a lot of research over the last decades as to if vitamin C should be consumed when running. Some results say YES, while others show that there is no big difference.
One thing is sure however that taking Vitamin C with iron-containing food helps enhance the iron absorption and iron plays the very important role in getting oxygen to your muscles. Low iron – small transportation!!!
Vitamin C is said to aid the growth and repair of tissue in the body and limit fatigue and immune dysfunction. It isn’t stored in the body, so to get it, you have to consume it in your daily diet.
“A large orange or a cup of strawberries, chopped red pepper or broccoli provide enough vitamin C for the day.” Runners who participate in strenuous training for extensive periods of time may have increased needs for the vitamin.
