Are dietary supplements dangerous for health? Detailed analysis of risks and advantages
I. Definition and classification of dietary supplements

2.1. Lack of strict regulation and quality control
Unlike drugs, dietary supplements do not go through such a strict check for safety and efficiency. Dad manufacturers are not required to provide evidence of their effectiveness before the market. This means that many dietary supplements do not have a sufficient scientific base confirming their declared properties.
In addition, quality control of dietary supplements is often less strict than for drugs. This can lead to the inconsistency of the composition of the dietary supplement declared on the label, the presence of impurities and pollution, as well as to improper dosage of active substances.
2.2. Discrepancy between the composition of the declared on the label
Studies show that a significant part of the dietary supplement does not correspond to the composition indicated on the label. Some dietary supplements may contain fewer active substances than stated, while others can. This can lead to ineffectiveness of dietary supplements or to an overdose of active substances.
In addition, impurities and pollution, such as heavy metals, pesticides, bacteria and other harmful substances, can be found in the dietary supplement. These impurities can be a serious health hazard.

Bades containing St. John’s wort can reduce the effectiveness of antidepressants and contraceptives.
It is important to inform the doctor about all the dietary supplements in order to avoid undesirable interactions with drugs.
2.4. Side effects and allergic reactions

2.5. The risk of an overdose
Reception of dietary supplements in large doses can lead to an overdose of vitamins, minerals and other active substances. An overdose of some vitamins and minerals can be dangerous to health.

It is important to observe the recommended doses indicated on the Bad label, and not exceed them without consulting a doctor.

Reception of dietary supplements can mask the symptoms of serious diseases, postponing timely diagnosis and treatment.

It is important to consult a doctor to establish an accurate diagnosis and prescribe adequate treatment, and not self -medicate using dietary supplements.
2.7. Fraud and unfair advertising
The dietary supplement market is often an object of fraud and unfair advertising. Manufacturers can declare the miraculous properties of dietary supplements who do not have scientific confirmation, and use marketing strategies to be misleading.
