Hello,

1. Which minerals and in what ways (overdose from supplements or improper diet, illness...) accumulate in the body?
2. Can we actually overdose on minerals, or does the body only use the necessary amounts and excrete the rest? Or does this mechanism only work for vitamins?
Thank you for the clarification.

Each element performs a range of functions in the body. Some are used for immediate needs, while others are stored in depot tissues, and this system is regulated by the body's own requirements. Essentially, all elements are stored, but to different extents and in various locations, so it is not possible to generalize this process. In practice, it is possible to experience an "overdose" of any element, not only due to excessive supplementation but also through a regular diet. For example, if there is an excess of calcium, which is relatively common, this element is most often deposited in soft tissues, leading to calcification (most commonly in arteries, potentially developing atherosclerosis).

The system of element metabolism is highly complex and occurs in the body through enzymatic reactions. Elements have mutual antagonistic relationships, meaning they both compete and cooperate with each other. If a metabolic disorder arises, or there is a significant deficiency or, conversely, an excess of certain elements, their metabolism can deviate from equilibrium, resulting in increased deposition of minerals in tissues where they essentially do not belong. Toxicity varies for each element in relation to its reference intake values.

Mgr. Martin Jelínek has been systematically involved in nutrition education since 1999. He is the founder of ATAC, the educational company behind NutriCourses, and the author of an educational system focused on nutrition, healthy lifestyle, and the practical application of nutrition knowledge.

He graduated from the Faculty of Science at Masaryk University in Brno. Throughout his professional career, he has combined nutrition, education, and the practical application of acquired knowledge. His educational system also includes the ZOF (Zone of Optimal Functioning) learning application, where students turn theory into practical work with meal plans.

In 2007, he launched the first intake of a six-month course focused on the education of nutrition advisors. Over time, this course became the foundation for the further development of the educational system and a range of specialised courses.
