Nutrigenomics: Vitamin C

Posted by Athletigen on Tue, Mar 05, 2019

vitamin-CVitamin C plays many important roles in your body and can directly impact your athletic performance. In addition to helping protect your cells from free-radicals and playing a central role in the building of collagen, vitamin C supports the metabolism of vitamin E and iron. Vitamin C also helps reduce the respiratory discomfort associated with working out in cool temperatures.

Colorful fruits and vegetables are the best sources of dietary vitamin C.

Signs of vitamin C deficiency include slow healing, prolonged bruising and poor dental health. Too much vitamin C can increase your risk of developing kidney stones.

It's important to ensure you're getting enough daily vitamin C, but did you know that your DNA plays a role in your vitamin C levels?

The SLC23A1 gene influences how well your body absorbs and stores vitamin C and is primarily active in your kidneys. If you have a certain variant of this gene, you could be at risk of lower vitamin C levels.

It is easy for most people to reach their recommended daily vitamin C intake. For adults, this ranges from 75 mg/day to 95 mg/day for women and men, respectively. Pregnant and breastfeeding women require 85 mg/day and 120mg/day of vitamin C in their diets.

Here are some ways you can increase your vitamin C intake:

  • Substitute some of your energy drinks or soda with fruit juices. Be careful as some juices contain a lot of sugar.
  • Add raw, colorful fruits and vegetables to your snacks.
  • Help your body recover from heavy training or injury by adding additional vitamin C to your diet.
  • As always, consult with a medical or nutritional practitioner before making substantial changes to your diet.
