Micronutrients: Vitamins & Minerals for Athletes

Why Micronutrients Matter

While macronutrients provide energy, micronutrients ensure your body actually functions. They're involved in hundreds of biochemical processes – from muscle contraction to immune defense.

Athletes have an increased need for certain vitamins and minerals due to intense training. The most common deficiencies among athletes involve vitamin D, iron, magnesium, and zinc.

The 5 Most Important Micronutrients for Athletes

  • Vitamin D: Over 80% of Northern Europeans are deficient. Important for bone health, immune system, and muscle strength. Recommendation: 2,000–4,000 IU daily (especially in winter).
  • Magnesium: Involved in over 300 enzyme reactions. Prevents muscle cramps and improves sleep quality. Recommendation: 400–600 mg daily.
  • Zinc: Essential for testosterone production and immune function. Recommendation: 15–30 mg daily.
  • Iron: Oxygen transport in the blood. Women and endurance athletes are particularly affected. Recommendation: 8–18 mg daily (only supplement with confirmed deficiency!).
  • Omega-3 Fatty Acids: Anti-inflammatory, promotes recovery. Recommendation: 2–3 g EPA/DHA daily.

Food Before Supplements

The golden rule: cover micronutrients through diet first. A varied diet rich in vegetables, fruits, nuts, and whole grains covers most needs.

Supplements should complement, not replace. When in doubt, get a blood panel before supplementing randomly – especially for iron, vitamin D, and B12.

Frequently Asked Questions

How much protein do I need per day?+

Optimal protein intake depends on your goal: 1.6–2.2 g/kg body weight for muscle building, 2.0–2.4 g/kg during a diet, and 0.8–1.0 g/kg for general health. Use our Protein Calculator for an individual calculation.

Are carbs bad for weight loss?+

No! Carbs don't make you fat – a calorie surplus does. Carbohydrates are the best energy source for intense training. Low-carb diets only work because they often reduce total calorie intake.

What's the difference between good and bad fats?+

Unsaturated fats (olive oil, avocado, nuts, fish) are healthy and essential. Trans fats (processed foods, fried foods) should be avoided. Fat is important for hormones and vitamin absorption.

How can I accurately calculate my calories?+

First calculate your BMR (Basal Metabolic Rate) and multiply by your activity factor to get TDEE. Use our Calorie Calculator for precise calculation. For fat loss subtract 300–500 kcal, for muscle building add 200–300 kcal.

Is meal prep really necessary?+

Meal prep isn't necessary, but very helpful. It saves time (1–2h on Sunday instead of daily cooking), money (fewer impulse purchases) and helps you stay on track since you know exactly what you're eating.
