Systematic Nutritional Supplementation – Why Diagnostics Before Taking Supplements Matter
Dear Patients,
Vitamin supplements, iron capsules, magnesium, zinc or herbal remedies: nutritional supplements have long been part of our everyday lives. They promise more energy, stronger immune systems or better sleep, are available over the counter and are usually well-intentioned. However, many people take such supplements on their own initiative without knowing whether their body actually needs them or can utilize them properly. The problem is that what is lacking can be replaced, but too much can be harmful.
The danger of self-medication
The body only needs vitamins and minerals in very small amounts. A balanced diet usually covers these requirements. Taking them indiscriminately “just to be on the safe side” can therefore not only be unnecessary, but also harmful to your health. For example, vitamin D is often taken as a precaution in winter.
However, an overdose can cause kidney damage. Excessive amounts of vitamin A can put strain on the liver. Iron supplements should only be taken if there is a proven iron deficiency, as they can otherwise cause vascular calcification or organ damage.



B vitamins: when the body can’t process them properly
B vitamins: when the body can’t process them properly
B vitamins are a special case, as they are crucial for energy metabolism, nervous system function and numerous enzyme reactions. Vitamin B12 and folic acid (vitamin B9) are particularly noteworthy. They play a central role in the so-called methylation cycle, a biochemical process that is responsible, among other things, for detoxification, DNA formation and nervous system function.
In some people, however, this cycle does not function properly, for example due to a genetic mutation in the MTHFR enzyme.
The result:
- The ingested vitamins cannot be converted into their active form.
- Despite taking dietary supplements, symptoms such as fatigue, irritability or concentration problems persist.
- The homocysteine level in the blood remains elevated, which is considered a risk factor for vascular disease.
Only targeted diagnostics, such as genetic testing or laboratory analysis, can reveal whether a methylation disorder is present. In such cases, only active forms of vitamins that bypass the defective step in metabolism can help.
Hormones in focus
Another key aspect of prevention concerns hormone levels. Testosterone deficiency is not uncommon in middle-aged men. However, many are unaware that such a deficiency can have far-reaching effects on metabolism, energy levels and body composition.
Testosterone promotes muscle mass growth, increases basal metabolic rate (energy consumption at rest) and influences fat distribution.
Furthermore, even when vitamins and micronutrients are taken correctly, the desired effect is often not achieved if hormonal blockages exist.
At the Alpstein Clinic, we therefore also check hormone status as part of our prevention programs, if necessary, in order to obtain a complete picture. This allows us to consider targeted, medically supervised therapy.

Conclusion: less is more – but only if it’s the right thing
Dietary supplements can be very helpful, but only when tailored to real needs.
Prior diagnostics are not a luxury, they are an investment in long-term health.
