Let's Talk About Vitamin C
When you train regularly, nutrition is about more than just getting enough calories. Your body needs a wide range of vitamins and minerals to support normal function, and vitamin C is one of the most important.
Vitamin C is an essential nutrient, meaning your body cannot produce it on its own. It plays several important roles in the body, from supporting normal immune function to helping protect cells from oxidative stress.
Supports a healthy immune system
One of the best-known roles of vitamin C is supporting normal immune function. Regular training is an important part of a healthy lifestyle, but hard training sessions also place additional demands on the body.
Getting enough vitamin C as part of a balanced diet helps support the normal function of your immune system. For athletes, this is particularly relevant when training consistently, travelling for competitions or juggling a demanding training schedule.
Vitamin C is found naturally in foods such as oranges, grapefruit, strawberries, kiwi fruit, peppers, broccoli and tomatoes.
Helps protect cells from oxidative stress
Exercise increases oxygen use throughout the body. This is a normal part of physical activity, but it can also increase the production of compounds known as free radicals.
Vitamin C acts as an antioxidant, helping protect cells from oxidative stress caused by free radicals. This is one reason why a varied diet rich in fruit and vegetables is such an important part of an athlete's overall nutrition.
The goal isn't to eliminate oxidative stress. Some of the body's responses to exercise are part of the normal training process. Instead, the focus should be on providing your body with the nutrients it needs to function properly.
Supports collagen formation
Vitamin C also contributes to normal collagen formation.
Collagen is an important structural protein found throughout the body, including in connective tissue, skin, bones and cartilage. For athletes, maintaining healthy connective tissues is an important part of supporting an active lifestyle.
Vitamin C therefore has a role that extends well beyond simply supporting the immune system.
Helps with iron absorption
Another useful benefit for active people is vitamin C's role in iron absorption.
Iron is involved in normal red blood cell formation and oxygen transport. Vitamin C can increase the absorption of iron from plant-based foods, making foods such as beans, lentils and leafy greens particularly useful when combined with vitamin-C-rich foods.
For example, adding peppers or tomatoes to a meal containing beans or lentils can help increase the amount of iron your body absorbs.
Getting enough vitamin C
For most people, the best approach is to get vitamin C through a varied and balanced diet. Fresh fruit and vegetables can provide plenty of vitamin C while also supplying other vitamins, minerals and beneficial plant compounds.
For athletes, nutrition is about consistency rather than searching for one magic ingredient. Vitamin C won't replace quality training, adequate sleep, hydration or a well-balanced diet. But it is one of many essential nutrients that help your body perform its normal functions.
At Racefood, we believe good sports nutrition starts with understanding what your body actually needs. Vitamin C is a small part of the bigger picture, but making sure you're getting enough can help support your health and keep you ready for the next session.
