Age might determine the amount of energy and nutrient requirement of athletes. Older women need more of B12 and D because of the body’s compromised ability to absorb it.

Competitive intensity and sport type

Difference in the requirement of nutrients. High-intensity sports need more of the vitamins.

Dietary restrictions

Vegetarian and vegetarian’s athletes’ major concern. Such athletes aren’t able to get most of the vitamins easily accessible in animal products.

Environmental Factors

Women who are training in high-altitude or cold environments may also need to consume extra amounts of some vitamins due to the elevated metabolic demands and oxidative stress.

Meeting Daily Vitamin Needs For women engaged in sports, comprehensive and well-balanced daily delivery of vitamins from food is fundamental.

Here are some general recommendations to help in the provision of vitamin requirements:

  • Diversify your diet by introducing a wide variety of fruits, vegetables, whole grains, lean proteins, and healthy fats;
  • Consider supplementation in some situations when the balance of vitamins is not able to be provided through nutrition. However, supplementation should be discussed with a qualified physician;
  • Monitor the blood level and adjust the vitamin intake with supplementation in accordance with the data received. There is no sense in taking more than needed;
  • Hydrate. Water is essential for all biochemical reactions in the body. It also supports vitamin absorption into the bloodstream and use in cellular activities.

By understanding the women’s specific needs and focusing on the right daily vitamin intake, professional or amateur women athletes can be sure that they consume enough of the elements they need for the best biological performance.

Regular monitoring and additional provision of vitamins, if necessary, also contribute to hormone balancing and metabolic regulation, increasing the absorption and use of proteins and carbohydrates.
