Настройки на бисквитките Vitamin A - Royal Canin



also known as: Retinol

La vitamine A joue un double rôle pour l'organisme.

Vitamin A deficiency causes:

  • eye problems (reduced night vision, opacification of the cornea, dryness of the conjunctiva) ;
  • skin problems (dry skin, atrophy of the sebaceous glands);
  • reproduction anomalies;
  • greater sensitivity to infections and pulmonary complications.

An excess of vitamin A is also harmful to the body (joint problems, reproduction problems).

A little background information

In antiquity, liver was used to treat some visual disorders. Vitamin A was isolated in 1913 and its chemical structure was mapped in 1931. It is a long-chain alcohol that is soluble in fat. It is absorbed in the small intestine and stored in the liver. Beta carotene is a vitamin A precursor for dogs, but cats are unable to realise this synthesis.

Its role in the body

  • Vision: adaptation to darkness.
  • Reproduction: synthesis of certain hormones.
  • Metabolism: synthesis of proteins.
  • Skin and hair : regulates the growth of epidermis cells and the production of sebum. Vitamin A helps fight seborrhoea and the dandruff that often forms after pruritus. It acts in synergy with zinc and sulphur amino acids.

Natural sources

As retinol: liver, meat, fish, eggs, dairy products.
