Supplements.

Vitamins are organic compounds needed in small amounts for different normal body functions. Each vitamin has its own role.

They include fat-soluble vitamins A, D, E and K, and water-soluble vitamin C and the B vitamins. A variety of foods is the basis for obtaining them.

Multivitamins combine several vitamins and often include minerals or trace elements. Formulations and amounts differ between products.

Comparisons should consider the ingredients and quantities per recommended daily dose. A long ingredient list does not mean that a product meets every nutritional need.

Minerals and trace elements are inorganic nutrients. Trace elements, including iron and zinc, are required in very small amounts.

Their roles differ: calcium contributes to bone structure, while iron is a component of haemoglobin. The guide provides separate information on individual nutrients.

Specialist formulas combine selected ingredients in specified amounts and forms. They may contain vitamins, minerals, fatty acids or other ingredients.

Each formulation should be considered alongside its directions and precautions. A formula’s name alone does not establish therapeutic properties.

Capsules enclose their contents in a shell, while tablets are solid forms made from compressed ingredients. The format depends on the formulation and intended use.

The amount per capsule or tablet is not necessarily the daily dose. Follow the individual product’s directions rather than treating different formats as interchangeable.

Effervescent tablets are dissolved in water before consumption, producing a drink containing the ingredients.

The amount of water, number of tablets and frequency of use are specified in each product’s directions. An effervescent format does not mean that different formulations contain the same nutrients or amounts.
