B vitamins: functions and deficiencies

The lack of all or some B-complex vitamins is more frequent than we can imagine, above all because deficiency states can occur during frequent events, such as:

  • protracted vomiting;
  • diarrhea;
  • convalescence and / or assisted nutrition (n.b .: the Vitamin B complex of the group should be added to all the therapies of animals that do not feed themselves, because they are indispensable for the hepatic metabolism of glucose in fats and proteins);
  • renal failure, due to poor appetite, and vomiting associated with polyuria which increases its loss, especially thiamine and niacin which can contribute to the worsening of anorexia;
  • disorders of the intestinal microflora due to treatment with sulfonamides and antibiotics;
  • pregnancy and lactation;
  • anemia;
  • paresis and tetany;
  • intense muscular work.

And then, being understood that, if lacking, all cause anorexia and weight loss, let’s get to know them better:

Vitamin B 1 ( thiamine )regulates the metabolism of carbohydrates and amino acids;Irregularity in growth.

enters the metabolism of collagen, so it is fundamental in the healing process.
Vitamin B 2 (riboflavin )essential for innumerable metabolic reactions at the level of tissues in particular skin and hair;Delayed growth.
antioxidant, together with the enzyme glutathione reductase;Apathy
stimulates the production of hydrochloric acid, thus promoting digestion.Anemia

it is necessary for the synthesis of sex hormones;Skin eruptions.
very important for brain metabolismIrritation of oral mucosa.
Vitamin B 5 (D-Calcium Pantothenate)It is the precursor of coenzyme A used by all cells in the body for the synthesis of fatty acids, for respiratory functions, for hormone synthesis and cholesterol, ...Fatigue.
supports the proper functioning of the adrenal glands;Fatty degeneration of the liver.
essential in protein synthesis.Alterations in the digestive tract.
Stopping growth.
Reduced antibody synthesis
Hair loss.
Vitamin B 6 (pyridoxine )significantly intervenes in the metabolism of amino acids (taurine, carnitine, niacin);Delayed growth.
implicated in iron metabolism;Microcytic anemia.
fundamental in carbohydrate and lipid metabolism;Convulsions.
important for muscle work and growth.Crystalline from calcium oxalate.
Kidney damage.
Vitamin B12 (cyanocobalamin)The metabolism of vitamin B12 is closely related to that of folic acid.Growth arrest (cat).
helps in fixing vitamin A in the body's tissues;Anemia.
necessary for DNA production;Skin lesions.
necessary in the Krebs cycle;Failure to coordinate movements.
stimulates the appetite;
relieves neurological disorders.
