Dietary supplements are usually described as products being the source of the concentrated nutritional components and others of physiological activity. Their popularity and easy availability for everyone may raise doubts.

Dietary supplements and drugs – comparison of legal requirements

Part I of the paper introduces specific legal requirements both for medicinal products and dietary supplements, including their application aims, labeling of packaging and contents of advertising leaflets. The attention was paid to point out significant differences between them. The main task of dietary supplements is to keep the equilibrium of the organism on the level assuring good health, whereas medicinal products are applied to restore equilibrium in the organism, disturbed by any disease. Production of medicinal products is only possible after confirmation of their effectiveness through suitably long clinical investigations, which is not required for dietary supplements. The packaging of medicinal products contains important information about the product and its potential adverse events. However, the packaging of diet supplements contains only indications and dosage recommended but one can seldom find any contraindication, which might suggest that diets supplements are safer than medicinal products.

Selected components of dietary supplements and their application

The dietary supplements mainly contain vitamins and minerals, and also among others: amino acids, fatty acids, fiber and different vegetable products. Supplements were divided because of the composition and their application. There are supplements helping slimming, correct vision and influencing appropriate organs of movement, concentration, condition of skin, hair and nails, relieving processes of aging, and also supplements for athletes and many other kinds. The attention was paid to the safety of supplementation in children and to the dietary supplements reducing cancer risk.

Interaction between dietary supplements and drugs

Dietary supplements can change working scheme of applied medicinal products through decrease in their absorption, increase of their excretion or disruption of metabolism. Many adverse events can occur due to simultaneous application of dietary supplements and medicinal products. Therefore it is very important that patients consult a doctor or a pharmacist before the application of any dietary supplement if no contraindications exist.
