Vitamins and minerals: buy as dietary supplements – a detailed guide
Chapter 1: Fundamentals of Vitamins and Minerals
1.1 The role of vitamins and minerals in the body:
Vitamins and minerals are micronutrients necessary for the normal functioning of the body. They participate in metabolic processes, support immunity, provide growth and development, and also protect cells from damage. Unlike macronutrients (proteins, fats and carbohydrates), vitamins and minerals are not a source of energy, but they are absolutely necessary for converting macronutrients into energy and for other vital functions.
1.1.1 Vitamins: These are organic compounds that the body cannot synthesize independently (or synthesizes in insufficient quantities) and should receive from food or additives. Vitamins are divided into two main groups:
-
Fat -soluble vitamins: (A, d, e, k) dissolve in fats and can accumulate in the body. Excess fat -soluble vitamins can lead to hypervitaminosis.
-
Water -soluble vitamins: (B-complex, C) dissolve in water and do not accumulate in the body in significant quantities. Excess water -soluble vitamins are usually excreted in urine.
1.1.2 Minerals: These are inorganic substances necessary for various biochemical reactions and structural functions. Minerals are divided into:
-
Macro elements: (Calcium, phosphorus, magnesium, sodium, potassium, chlorine, sulfur) are necessary in large quantities (more than 100 mg per day).
-
Microelements: (Iron, zinc, copper, manganese, iodine, selenium, chrome, molybdenum, fluorine) are necessary in smaller quantities (less than 100 mg per day).
1.2 The need to receive vitamins and minerals as dietary supplements:
In an ideal world, a balanced diet rich in various products should provide the body with all the necessary vitamins and minerals. However, in the modern world this is not always possible because of:
-
Dining of the soil: Intensive agriculture leads to the depletion of the soil and a decrease in the content of vitamins and minerals in agricultural crops.
-
Product processing and storage: The process of processing, storing and transporting foods can reduce the content of vitamins and minerals in them.
-
Unstable nutrition: Many people do not consume a sufficient amount of fruits, vegetables and whole grains, which leads to a deficiency of the necessary micronutrients.
-
Age -related changes: With age, the body’s ability to absorb some vitamins and minerals decreases.
-
Certain health states: Some diseases or conditions (for example, pregnancy, lactation, chronic diseases) increase the need for certain vitamins and minerals.
-
Restrictive diets: Vegetarianism, veganism and other restrictive diets can lead to a deficiency of certain vitamins and minerals (for example, vitamin B12, iron, calcium).
In these cases, taking vitamins and minerals as biologically active additives (dietary supplements) can be useful for maintaining health and preventing deficiency.
1.3 Differences of dietary supplements and medicines:
It is important to understand the difference between dietary supplements and drugs. Medicines undergo strict clinical trials and must comply with certain quality and efficiency standards. Bades, on the contrary, are adjusted less strictly.
-
Regulation: Bades are usually regulated as food, and not as medicines. This means that dietary supplement manufacturers are not required to prove their effectiveness or safety as strictly as manufacturers of drugs.
-
Appointment: Medicines are intended for the treatment or prevention of diseases. Bades are designed to maintain health and replenish the deficiency of nutrients.
-
Dosage: The dosage of drugs is strictly controlled and prescribed by a doctor. The dosage of dietary supplements is usually indicated on the packaging, but it may not always be optimal for each person.
-
Quality: The quality of the drugs is strictly controlled. The quality of dietary supplements can vary depending on the manufacturer.
