Vitamin B6, Pyridoxine -Deficiencies can cause arthritis

[Guest guest]

Pyridoxine is involved in more bodily functions than almost any other single

nutrient. It affects both physical and mental health. It is necessary for

the production of hydrochloric acid and the absorption of fats and protein.

Pyridoxine also aids in maintaining sodium and potassium balance, and

promotes red blood cell formation. It is required by the nervous system, and

is needed for normal brain function, and for the synthesis of the nucleic

acids RNA and DNA, which contain the genetic instructions for the

reproduction of all cells and for normal cellular growth. It activates many

enzymes and aids in the absorption of vitamin B12, in immune system

function, and in antibody production.

Pyridoxine acts as a mild diuretic, reducing the symptoms of premenstrual

syndrome, and it may be useful in preventing oxalate kidney stones as well.

It is helpful in the treatment of allergies, arthritis, and asthma.

Deficiencies

A deficiency of vitamin B6 may be recognized by anaemia, convulsions,

headaches, nausea, flaky skin, a sore tongue, and vomiting. Other possible

signs of deficiency include acne, anorexia, arthritis, conjunctivitis,

cracks or sores on the mouth and lips, depression, dizziness, fatigue,

hyperirritability, impaired wound healing, inflammation of the mouth and

gums, learning difficulties, weak memory, hair loss, hearing problems,

numbness, oily facial skin, stunted growth, and tingling sensations. Carpal

tunnel syndrome has been linked to a deficiency of vitamin B6 as well.

Antidepressants, estrogen therapy, and oral contraceptives may increase the

need for vitamin B6. Diuretics and cortisone drugs block the absorption of

this vitamin by the body.  

Sources

All foods contain some vitamin B6; however, the following foods have the

highest amounts: brewer's yeast, carrots, chicken, eggs, fish meat, peas,

spinach, sunflower seeds, walnuts, and wheat germ. Other sources include
