Vitamins, minerals, and more

Approximately 20% of the population experiences vitamin D deficiency, and over 50% do not consume enough magnesium through their diet. As a sports nutritionist with 15 years of experience, I can confirm that optimal intake of vitamins and minerals is the foundation for achieving high athletic performance and maintaining overall health. Even with a balanced diet, intense training and stress increase the need for these micronutrients.

Modern studies, including ISSN position stands, highlight the role of vitamin and mineral supplements in supporting immune function, energy metabolism, and recovery after exertion. The lack of even one key element can disrupt a cascade of biochemical processes, leading to fatigue, reduced performance, and an increased risk of injuries.

In my practice, I observe that adequate intake of zinc and B vitamins significantly improves recovery for my clients, especially after periods of overtraining. Do not underestimate the importance of these "small" components for the overall functioning of the body.

The choice of appropriate supplements should be based on individual needs, diet, and goals. Consult a specialist for the dosage and combination that is most suitable for you to optimize the effect and avoid unwanted interactions.

Vitamins and Minerals: Foundation for Health and Athletic Performance

In today's fast-paced world, where intense training and daily stress are part of many people's lives, and food is often processed and poor in micronutrients, adequate intake of vitamins and minerals is paramount. These micronutrients form the basis of every biological function in the body, from energy production and immune defense to tissue recovery and hormone regulation. Without them, even the strictest diet and training plan will not yield the desired results.

Why are vitamins and minerals vital?

Vitamins and minerals don't just sustain life – they optimize every aspect of it. Here's why they are so important:

Food supplements do not replace a varied diet.

Vitamin D, Magnesium, Zinc: The Three Most Important Micronutrients for Athletes

In my practice with over 1500 athletes over the years, I've found that three micronutrients are almost always deficient in active individuals: vitamin D, magnesium, and zinc. A study by the Bulgarian Agricultural Academy shows that over 70% of Bulgarians have insufficient vitamin D levels during the winter months (October–April). For athletes, this deficiency directly impacts muscle strength, immunity, and recovery. The recommended daily dose is 2000–4000 IU of vitamin D3, ideally in combination with vitamin K2 (MK-7 form) for optimal calcium absorption into the bones, not the arteries.

Magnesium participates in over 300 enzymatic reactions in the body. For athletes who sweat intensely, daily needs increase to 400–500 mg. I recommend bioavailable forms such as magnesium bisglycinate or citrate – avoid cheap magnesium oxide, which has less than 4% absorption. Zinc is critical for testosterone synthesis and immunity – 15–30 mg daily, ideally as a ZMA complex (zinc + magnesium + B6) before bed for better sleep and recovery.

Multivitamins for Men, Women, and Seniors: What's the Difference?

Multivitamins are not one-size-fits-all – the formula should match gender, age, and physical activity level. Multivitamins for men typically contain higher doses of zinc (for testosterone), selenium (for prostate health), and B vitamins for energy metabolism, with no or low iron. Multivitamins for women contain increased iron (due to the menstrual cycle), folic acid, calcium, and vitamin B6 for hormonal balance. Multivitamins for adults over 50 emphasize vitamin B12 (absorption decreases with age), vitamin D, calcium, and coenzyme Q10 for heart health.

For elite athletes, I recommend specialized sports multivitamins with electrolytes, antioxidants (vitamin C 500–1000 mg, vitamin E), and adaptogens. Well-known brands like Animal Pak by Universal Nutrition, Opti-Men by Optimum Nutrition, or our own SZ Sport line offer options formatted for various needs.

Vitamins for Children and Teen Athletes

Growing children and teenagers who exercise regularly have specific needs. Calcium (800–1300 mg) and vitamin D (600–1000 IU) are critical for building peak bone mass up to age 25. B vitamins support concentration and energy in school and during training. Omega-3 (DHA) supports brain development and focus. Always choose tablets or syrups without artificial colors and sugar, ideally with natural fruit flavorings. I recommend consulting a pediatrician before starting any supplement for children under 12 years old.

Vitamins for Immunity: Real Protection or Marketing?

Vitamin C is popular for immunity, but studies show that intake above 1000 mg daily does not reduce the frequency of colds – it only shortens their duration by about 8%. More effective for the immune system are: vitamin D (supports T-cell response), zinc (directly inhibits viral replication – I recommend 15–30 mg at the first symptoms), quercetin (a bioflavonoid with antiviral properties), and probiotics (70% of the immune system is in the gut). For intensely trained athletes, whose immunity decreases after heavy workouts (the so-called "open window" effect), glutamine 5–10 g after training also helps.
