Introduction
Micronutrients, namely vitamins and minerals, are vital components of an athlete’s diet, contributing significantly to overall health, performance, and recovery.
In sprinting, speed, power, and quick recovery are paramount. Micronutrients contribute to these aspects in several ways.
Micronutrients such as Vitamin D, Iron, Magnesium and Zinc among others are essential in allowing sprinters to perform by promoting optimal muscle function, energy production and improving recovery time among other benefits.
In this article I will give a a broad overview of the key vitamins and minerals that I will discuss today, before jumping into more detail on each one in particular.
Overview of Micronutrients for Sprinters and Athletes
Vitamin D: Supports bone health, muscle function, and immune function. Deficiency can lead to impaired performance and increased risk of injury. Recommended intake for adults is 15-20µg/day.
Iron: Essential for oxygen transport in the body, supporting energy production and endurance. Particularly important for female athletes who may be at risk of iron deficiency. Recommended intake for adult men is 8mg/day and for women (aged 19-50) it’s 18mg/day.
Magnesium: Involved in muscle contraction and relaxation, energy production, and protein formation. Can help improve performance and recovery. Recommended intake for adult men is 400-420mg/day and for women it’s 310-320mg/day.
Zinc: Supports immune function, protein synthesis, and energy metabolism. Recommended intake for adult men is 11mg/day and for women it’s 8mg/day.
B-Vitamins: Essential for energy production and red blood cell formation. Can enhance performance and speed up recovery. Recommended intake varies for each B-Vitamin, but generally ranges from 1.3 to 18mg/day for adults.
Antioxidants (Vitamin C, Vitamin E, Beta-Carotene, Selenium): Neutralize harmful free radicals produced during intense exercise, reducing inflammation and promoting quicker recovery. Recommended intake varies for each antioxidant, but for adults: Vitamin C (75-90mg/day), Vitamin E (15mg/day), Beta-Carotene (no set recommendation, but incorporated within 700-900µg/day of Vitamin A), Selenium (55µg/day).

Vitamin D for Sprinters
Overview of Vitamin D and Its Benefits
Vitamin D, often referred to as the “sunshine vitamin,” is a fat-soluble vitamin that plays a crucial role in calcium absorption, bone health, and immune function.
Moreover, it has garnered attention in sports science due to its significant influence on muscle function and performance.
Role of Vitamin D in Muscle Health and Injury Prevention for Sprinters
Vitamin D plays a critical role in muscular function and strength, with deficiencies linked to impaired muscle function, increased risk of strains, and delayed recovery.
Research indicates that adequate levels of vitamin D may contribute to improved muscle function, reduced inflammation, and decreased risk of injury, particularly muscle pulls and strains that are common in sprinting.
In addition, some studies suggest that vitamin D might enhance fast-twitch muscle fibre function, a crucial aspect for sprinters who rely on these fibres for explosive power and speed.
As you can tell, Vitamin D is extremely important for sprinters and power-based athletes in general (there’s a reason I listed it first….). Now let’s move onto suggested intake and sources.
Suggested Intake and Sources
For most adults a common recommendation is 600 to 800 IU per day. Although, for sprinters and other power-based athletes, I’d recommend at least 1000 IU.
Sunlight is the most natural source of vitamin D. However, in regions with limited sunlight or during winter months, it may be challenging to get sufficient vitamin D from sunlight alone.
In such cases, food sources like fatty fish, fortified dairy products, and egg yolks, as well as vitamin D supplements, can help meet the required intake. I personally recommend a vitamin D supplement, which generally contains 1000 IU of vitamin D per capsule (seen below).
A daily dosage of 1000 UI of Vitamin D is generally enough for athletes; however, I’ve heard of some coaches recommending several thousand UIs. There is some research that suggests athletes require more vitamin D than average, however there are also side effects associated with consuming too much Vitamin D that you should be wary of.
Iron for Sprinters
Understanding the Role of Iron in Oxygen Transport
Iron is an essential mineral primarily known for its role in oxygen transport throughout the body.
It is a key component of haemoglobin, a protein in red blood cells that carries oxygen from the lungs to the body’s tissues, and myoglobin, a protein that provides oxygen to muscles.
Without sufficient iron, the body cannot produce enough of these oxygen-carrying proteins, leading to impaired athletic performance.
The Importance of Iron for Sprinters
For sprinters, having an adequate iron status is crucial. While sprinting is primarily an anaerobic activity, meaning it doesn’t rely heavily on oxygen for energy, iron is still vital.
It plays a role in energy production and is involved in various metabolic processes. Additionally, iron is necessary for optimal muscle function and recovery.
Moreover, iron deficiencies can lead to decreased athletic performance, increased fatigue, and impaired recovery, all of which can negatively impact an athlete’s performance. In severe cases, iron deficiency can lead to iron deficiency anaemia, a condition that significantly reduces exercise capacity and performance.
Iron Absorption and Recommended Intake
Iron absorption can be influenced by various dietary factors. Vitamin C (we’ll get to that later) can enhance iron absorption, so consuming iron-rich foods with foods high in vitamin C, such as citrus fruits or bell peppers, can be beneficial. Conversely, certain substances like caffeine and calcium can inhibit iron absorption.
Generally, adult men need about 8 mg per day. Athletes, particularly those in endurance sports, may require more.
Those small orange balls are the iron that allow haemoglobin to perform its function of transporting oxygen.
Magnesium for Sprinters
Understanding the Role of Magnesium
Magnesium is an essential mineral involved in over 300 enzymatic reactions in the body.
It plays crucial roles in energy production, protein synthesis, muscle and nerve function, and blood glucose control.
It also contributes to the structural development of bone and is necessary for the synthesis of DNA, RNA, and the antioxidant glutathione.
Importance of Magnesium for Sprinters
For sprinters, magnesium has several implications for performance and recovery. It’s involved in muscle contraction and relaxation, and an adequate magnesium status can help prevent muscle cramps and spasms, common issues in sprinting.
Moreover, magnesium aids in energy production, and a deficiency can affect a sprinter’s power output and overall performance.
Additionally, magnesium has been linked to improved sleep quality, which is essential for optimal recovery and performance.
It also plays a role in protein synthesis, aiding muscle recovery and growth, vital aspects for sprinters who undergo intense training sessions.
Recommended Intake and Sources
The recommended dietary allowance for magnesium varies by age and sex. For adult men, it’s typically around 400-420 mg per day, while for adult women, it’s about 310-320 mg per day. Athletes may have slightly higher requirements due to increased magnesium losses through sweat.
Magnesium deficiency is relatively common, often due to inadequate dietary intake or losses through sweat in athletes as previously stated. Therefore, it’s important for sprinters to ensure they’re meeting their magnesium needs through diet, and potentially, supplementation.
If you wish to take Mg as a supplement, you will find that there are many different forms. Generally speaking, while there may small differences between them, most magnesium supplements should work well.
Zinc for Sprinters
Understanding the Role of Zinc
Zinc is a vital trace mineral that plays a role in numerous enzymatic reactions in the body.
It is essential for immune function, protein synthesis, wound healing, DNA synthesis, and cell division. Additionally, zinc plays a critical role in the process of physical growth and development, neurological function, and reproduction.
Understanding the Role of Zinc
For sprinters, adequate zinc levels are critical for maintaining peak athletic performance. Zinc is involved in energy metabolism, aiding in the conversion of food into usable energy, which is crucial for the high-intensity efforts required in sprinting.
Moreover, zinc plays a crucial role in the growth and repair of muscle tissue, promoting recovery after strenuous workouts. It also supports a robust immune system, helping athletes stay healthy during heavy training periods.
Recommended Intake and Sources
The recommended dietary allowance for zinc varies by age and sex. Adult men require about 11 mg per day, while adult women need 8 mg per day. Sprinters, due to their high level of physical activity, may have slightly increased needs.
Zinc can be found in a variety of foods, including meat, shellfish, legumes, seeds, nuts, dairy, eggs, and whole grains. However, because the body has no specialized zinc storage system, it is crucial to get enough of this micronutrient daily.

B-Vitamins for Sprinters
Understanding the Role of B-Vitaminsc
B-vitamins are a group of water-soluble vitamins that play key roles in cellular metabolism. They are essential for converting the food we eat into energy that our bodies can use.
The B-vitamin complex includes B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folate), and B12 (cobalamin).
Importance of B-Vitamins for Sprinters
B-vitamins are particularly important for sprinters due to their role in energy production. They aid in metabolizing carbohydrates, fats, and proteins to produce energy, which is critical for high-intensity exercise like sprinting.
In addition, certain B-vitamins, such as B6 and B12, are involved in the production of red blood cells, which transport oxygen to the muscles.
This is crucial for endurance and performance in sprinting. B-vitamins also support optimal nervous system function, important for reaction times and coordination.

Antioxidants for Sprinters
Understanding the Role of Antioxidants
Antioxidants are compounds that help protect the body’s cells from damage caused by free radicals, which are produced during normal metabolic processes and during exercise.
These include vitamins such as vitamin C, vitamin E, and beta-carotene, as well as minerals like selenium.
Importance of Antioxidants for Sprinters
Sprinters, given the intensity and frequency of their training, often produce a high number of free radicals.
This can lead to oxidative stress, which can damage cells and impair muscle function and recovery. Antioxidants help to neutralize these free radicals, reducing inflammation and promoting quicker recovery after workouts.
In addition, antioxidants can support immune function, which can be compromised with heavy training. This makes sprinters less likely to get sick, which can disrupt their training and performance.
Source of Antioxidants
Antioxidants are found in a wide variety of foods. Vitamin C can be found in fruits and vegetables, especially citrus fruits, bell peppers, strawberries, and broccoli.
Vitamin E is present in nuts, seeds, and vegetable oils.
Beta-carotene is abundant in colourful fruits and vegetables like carrots, sweet potatoes, and spinach.
Selenium is found in seafood, meat, and grains.
Berries are a classic example of antioxidants
Conclusion
