What Are Multivitamin Supplements?

Multivitamin supplements are food supplements based on different types of vitamins, essential nutrients for the functioning and well-being of the organism.



Within these products, vitamins are contained in a concentration that satisfies the individual's daily nutritional needs.

Multivitamin supplements can be formulated in different forms, of course, to be taken orally. These include tablets, capsules, powders and solutions.

Composition

What Do Multivitamin Supplements Contain?

Multivitamin supplements contain a blend of different vitamins that perform multiple activities within the body. The most commonly used in supplements are:

  • Vitamin A: it is a vitamin involved in numerous functions of the organism and equipped with a powerful antioxidant effect. In particular, vitamin A is essential:
    • For the proper functioning of sight (including twilight vision);
    • For sexual maturation in adolescents;
    • For adult fertility.
  • B vitamins: there are eight B vitamins in total (B1, B2, B3 or PP, B5, B6, B8 or H, B9 or folate, B12). These are nutrients capable of performing numerous functions, as different as they are important and essential for the body. In detail, they mainly play a role of coenzymes in various cellular and metabolic processes and are involved:
    • In the metabolism of carbohydrates, proteins, lipids, amino acids, etc .;
    • In the synthesis of cholesterol and steroid hormones;
    • In the synthesis of nucleic acids;
    • In the reproduction of red blood cells and white blood cells;
    • In the proper functioning of the nervous system.
  • Vitamin C: : also known as ascorbic acid, vitamin C is perhaps one of the best known vitamins due to its antioxidant activity, but its functions within the body are much wider. Among these, we mention some:
    • Biosynthesis of collagen;
    • Synthesis of neurotransmitters such as noradrenaline;
    • Biosynthesis of bile acids;
    • Intestinal absorption of iron;
    • Promotes the use of selenium at physiological doses;
    • Activation of folic acid in tetrahydrofolic acid (the biologically active form);
    • Regulation of endogenous histamine levels;
    • Protection - in association with vitamin E - from damage caused by free radicals;
    • Stimulation of immune function (stimulation of the synthesis of interferons and immunoglobulins G and M).
  • Vitamin D3: also known as calciferolo, vitamin D3 is widely known for its important functions in bone health. In fact, it is involved:
    • In the absorption of calcium in the digestive system;
    • In the deposition of calcium in the bone tissue;
    • In the reabsorption of calcium and phosphorus in the proximal convoluted tubule (therefore, at the renal level).
  • Vitamin E: vitamin E - o tocopherol, if you prefer - it stands out for its own strong antioxidant properties thanks to which it is capable of protect fabrics from the damages induced by free radicals. Going into more detail, this vitamin is able to:
    • Protect cell membranes by hindering the peroxidation of membrane phospholipids;
    • Protect lipoproteins from oxidation;
    • Protect Vitamin A from oxidation.
  • Vitamin KVitamin K is also involved in maintaining bone health, but it also plays an important role in the coagulation process.

Other Ingredients

In addition to the vitamins mentioned above, multivitamin supplements can be enriched with additional active ingredients, such as, for example:



  • Mineral salts: these are other essential nutrients for the well-being of the organism. Among the best known and most used in supplements, we find:
    • Soccer (it is essential for the well-being of bones and teeth; it also regulates the functioning of muscles and blood coagulation);
    • Chrome (this nutrient appears to have hypoglycemic properties);
    • Iron (nutrient involved in the synthesis of hemoglobin, it is essential for the transport of oxygen in the blood; at the same time, it is also involved in the synthesis of collagen, in the metabolism of nucleic acids and in the processes of cellular respiration);
    • Iodine (essential for the production of thyroid hormones);
    • Magnesium (it is part of the composition of over 300 types of enzymes in the body, it is involved in energy metabolism and muscle function);
    • Manganese (it is involved in many biological mechanisms useful for the health of the organism, such as, for example, coagulation, fertility, thyroid and immune system activity);
    • Molybdenum (it mainly performs coenzymatic functions);
    • Copper (it is involved in cellular respiration and facilitates the absorption of iron);
    • Selenium (it is involved in the metabolism of thyroid hormones and is a cofactor of antioxidant enzymes that protect cell membranes from oxidative stress);
    • Silicon (it is involved in the formation of some constituents of collagen, it also plays an important role in the metabolism of mitochondria and osteoblasts);
    • Zinc (it is part of numerous enzyme complexes, is involved in energy metabolism, has antioxidant properties and contributes to the maintenance of normal cognitive functions, visual capacity and the immune system).
  • Plant extracts containing molecules that may prove useful for supporting certain functions of the organism. Some examples of extracts used in supplements are: turmeric extracts (antioxidant properties), bilberry and cranberry extracts (antioxidant properties, support of visual and urinary function), ginseng extracts (adaptogenic properties) and green tea extracts (antioxidant properties).
  • Other nutrients which can perform beneficial actions for the body, such as: amino acids; phospholipids (such as phosphatidylserine); flavonoids; carotenoids; etc.
