Because of unique physiological and hormonal characteristics, female runners and athletes need specific nutrition plans that differ from those of their male counterparts. This tailored approach is essential for optimizing their performance and maintaining overall health. Now, let’s dig into some variations in micronutrient needs and understand why they are crucial for female athletes.


Ensuring adequate calcium intake is crucial for the well-being of female athletes, especially runners, due to its impact on hormones and bone health. Additional calcium is recommended for specific groups like postmenopausal female runners and younger counterparts experiencing absent or irregular menstruation.

Recommended Intake

The Recommended Dietary Allowance (RDA) for calcium for women aged 19 to 50 is 1,000 mg/day.

Age-Specific Adjustment

Women over 50 are advised to increase their calcium intake to 1,200 mg/day as they enter perimenopause and menopause. This is imperative because the decline in estrogen during this stage negatively affects bone health, and estrogen serves a protective role for bones.

To meet these calcium needs, consider incorporating the following sources into your diet:

  • Dairy Products: Such as milk, yogurt, and cheese.
  • Calcium-Fortified Foods: Examples include soy milk or orange juice.
  • Dark Leafy Greens: Like kale or collard greens.
  • Broccoli and Bok Choy: These vegetables contribute to your calcium intake.
  • Canned Sardines or Salmon with Bones: Excellent sources of both calcium and omega-3 fatty acids.
  • Blackstrap Molasses: A sweet addition with added nutritional benefits.

By including these calcium-rich foods, female athletes can support their overall health, addressing the specific nutritional requirements essential for optimal performance and bone strength.

Vitamin D

Securing sufficient vitamin D is vital for female athletes, particularly runners, as it facilitates calcium absorption, which is essential for bone health.

Geographical Considerations

Female runners residing in northern parts of the United States and Canada, where sun exposure is limited from October to April, need special attention to their vitamin D levels.

Recommended Intake

The Recommended Dietary Allowance (RDA) for vitamin D for women aged 19 to 70 is 600 IU/day.

Challenges in Dietary Sources

Obtaining enough vitamin D solely through food can be challenging. Therefore, supplementation may be necessary, forming a crucial part of nutrition plans, especially in sports nutrition for women.

To enhance your vitamin D intake, include the following sources in your diet:

  • Fatty Fish: Cod and salmon provide a natural source of vitamin D.
  • Egg Yolks: Another dietary component contributing to vitamin D levels.
  • Fortified Foods: Items like milk, soy products, and cereals are fortified with vitamin D, offering additional supplement options.

Female athletes can support calcium absorption by prioritizing vitamin D, fostering bone health, and optimizing performance.


Iron is crucial in nutrition for female athletes, especially for female runners, as it contributes significantly to overall performance.

Prevalence of Iron Deficiency

A considerable 15 to 35 percent of female athletes face iron deficiency, emphasizing its importance in their diets.

Vital Role in Performance

Iron is essential for athletic performance and oxygen transfer for cardiovascular activities like running.

Factors Affecting Iron Levels

Female runners may experience low iron levels due to various factors. Intense exercise can reduce iron absorption, increase iron loss through sweat, and contribute to the breakdown of red blood cells.

Unique Requirements for Women

Women generally have higher iron needs than men, primarily due to menstruation causing regular blood loss. Coupled with restrictive diets, this factor can further elevate the risk of iron deficiency in female runners.

To boost iron intake, consider incorporating these iron-rich foods into your diet:

  • Beef and Pork: Excellent sources of heme iron.
  • Eggs: A nutrient powerhouse for runners.
  • Shrimp and Turkey: Providing essential iron content.
  • Iron-Fortified Cereals: A convenient option for supplementation.
  • Lentils, Tempeh, and Kidney Beans: Plant-based sources of iron.
  • Recommended Daily Allowance (RDA): For women aged 19 to 50, the RDA for iron is 18 mg/day. Women over 50 and in menopause only need 8 mg/day, as they no longer lose iron through menstruation.

Prioritizing iron in the diet of female athletes, particularly runners, is essential for sustaining energy levels and promoting overall health.


Understanding RED-S: Nutrition Challenges for Female Runners


Ensuring proper nutrition for female athletes is crucial, and one concern is the risk of Relative Energy Deficiency in Sport (RED-S). This occurs when an athlete consistently consumes fewer calories than needed to meet the exercise demands and maintain normal body functions.

Symptoms of RED-S include

  • Absence or infrequency of menstruation (amenorrhea or oligomenorrhea).
  • Increased susceptibility to injuries, such as stress fractures, and compromised bone health.
  • Poor recovery from injuries.
  • Weight loss, decreased coordination, and muscle loss.

Female runners, in particular, require more calories per kilogram of fat-free mass than their male counterparts to support hormonal functions. Falling below the 30 kcal/kg FFM/day threshold can result in low energy availability. A minimum of 45 kcal/kg/FFM daily is recommended for a female runner’s diet.

Special Considerations for Female Distance Runners

There’s a heightened risk of RED-S among female distance runners who may restrict carbohydrates or calories, thinking it improves performance.

However, being excessively thin doesn’t necessarily translate to faster running. Instead, it may lead to injuries, bone loss, muscle loss, poor performance, and even an unhealthy obsession with food.

Importance of Carbohydrates

Carbohydrates are essential for runners, and women are more sensitive to a lack of carbs due to hormonal factors. Avoiding low-carb running is crucial.

Tips for Maintaining Energy Levels

Eating enough before and after workouts is key. Consider incorporating carbohydrates to meet energy needs.

For personalized nutrition advice, consulting with a team of dietitians can help female runners better understand and meet their specific nutritional requirements.


Fueling Female Athletes with Carb Loading


For female athletes, especially runners, carb loading may need a different approach than their male counterparts. Since female runners generally have a lower overall calorie intake, the practicality of carb loading might look a bit different.

Increasing carb intake to the levels seen in studies with male athletes (10 or more grams per kilogram of body weight) could be challenging for some female runners. This is because it might compromise getting enough protein and fat in their diet.

A more practical approach for female runners could be gradually increasing their carb intake (around 5g/kg) during a carb-loading phase. Instead of aiming for the higher end right away, slowly working up to 8g/kg is more realistic.

Pasta dishes can be an excellent choice for this purpose, as pasta is known for its high carb content and is often recommended for runners.

During exercise, ensuring an adequate carb intake is crucial. Energy gels and running chews can play a role here. It’s essential for women to find ones they enjoy to prevent glycogen depletion in their muscles, positively impacting muscle recovery.

Carb loading for women over 50 may vary based on several factors, emphasizing the importance of individualized approaches. Considerations include the activity level, training intensity, menopausal status, hormonal balances, food preferences, genetics, etc. There’s no one-size-fits-all solution in nutrition for female athletes.


Nutrition for Women Runners on Vegan and Vegetarian Diets


For women runners embracing vegan or vegetarian diets, there are crucial nutrition factors to consider.

Protein Intake

  • Plant-based and vegan runners may risk inadequate protein if their diet lacks a variety of plant-based protein sources.
  • Protein shakes with soy protein powder can be beneficial for these runners.

Sources of Plant Proteins

  • Include legumes (beans, lentils, peas), soy products, grains, and pseudo-grains (quinoa, amaranth, buckwheat).
  • Endurance athletes generally aim for a protein intake of 1.2 to 1.4 grams per kilogram of body weight per day.
  • As plant protein isn’t as easily absorbed, aiming for the higher end of this range is advisable.

Considerations for Fiber Intake

  • Many plant-based proteins are high in fiber, so runners should time their meals around training sessions to avoid gastrointestinal issues.
  • Vegan breakfast meal prep ideas with low-fiber options can be beneficial before running.

Iron and Vitamin B12

  • While women are generally more susceptible to iron deficiency, well-balanced plant-based diets don’t increase this risk.
  • Iron supplementation should only be considered with a diagnosed deficiency under medical guidance.
  • Vitamin B12 deficiency concerns vegan runners; fortified foods like plant milk, nutritional yeast, or cereals can help.
  • A B12 supplement is recommended if these fortified foods are not consumed regularly.

Overall Nutrition

  • Well-planned plant-based diets can fully meet the nutrition needs of female runners.
  • Consultation with a medical provider is crucial before considering iron supplements.
  • Transitioning to a plant-based diet requires thoughtful planning to meet all nutritional requirements for optimal performance and well-being.


Supplements for Female Runners


Regarding supplements for female runners, there’s no one-size-fits-all approach. Recommendations should be tailored to individual needs rather than applying blanket guidelines.

Individualized Considerations

  • For vegan athletes, vitamin D, fish oil, and Vitamin B12 might be recommended based on personal requirements.
  • Multivitamins are generally only necessary if deficiencies are identified, making periodic lab work beneficial to track nutrient levels.

Caution with Excess

  • Taking vitamins and minerals beyond daily requirements won’t boost performance or health and can be harmful.
  • High antioxidants like vitamins C and E may hinder recovery and disrupt performance.

Food-First Approach

  • Prioritize a food-first mentality in nutrition, addressing dietary adjustments before taking supplements.
  • Collaborate with a sports nutrition practitioner or dietitian for personalized guidance.

Guidance is Key

  • If supplementation is necessary, seek guidance from a healthcare practitioner to ensure appropriateness and safety.
  • Avoid products exceeding 100% of the daily intake of any mineral to prevent potential adverse effects.
  • Approaching nutrition with a personalized and cautious mindset, focusing on whole foods, ensures that female runners meet their nutritional needs without unnecessary supplements and potential health risks.


Other Considerations


Ensuring an adequate diet for female athletes involves considering several factors beyond nutrition.

Hydration Matters

  • While some females may not sweat as much as men, salty sweaters require extra attention to electrolytes.
  • Menstrual cycles can influence body water status, and women with high fluid needs should consider hydration packs for longer runs.
  • Electrolyte enhancements or flavored recovery drinks can appeal to those who prefer options other than plain water.

Alcohol Considerations

  • Alcohol may affect women differently, especially with age. Its impact after running, particularly on an empty stomach or with inadequate nutrition, requires careful attention.
  • Adequate hydration and nutrient intake from food before consuming alcohol are crucial to prevent hindrances in recovery and nutrition.

Collagen Supplementation

Female athletes over 50, dealing with constant injuries or joint pain, may benefit from supplementing with collagen to support their nutritional needs.

Importance of Magnesium

  • Magnesium is a vital mineral for runners, involved in over 300 chemical reactions in the body.
  • Many runners fall short of the recommended magnesium intake, impacting optimal performance and overall system functionality.
  • Incorporating these considerations into the female athlete’s diet ensures a comprehensive approach to nutrition, hydration, and overall well-being.




To maintain good health and enhance performance, female runners must adapt their nutrition to accommodate their distinct physiological and hormonal requirements. Prioritizing calcium, vitamin D, and iron intake is essential, along with ensuring an adequate calorie intake to support the demands of endurance training.
