Vitamin B6 (Pyridoxine)

Vitamin B6, also known as pyridoxine is part of the B group vitamins and is water-soluble and is required for both mental and physical health.

Vitamin B6 - pyridoxine - is required for:
Pyridoxine is required for the balancing of hormonal changes in women as well as assisting the immune system and the growth of new cells. It is also used in the processing and metabolism of proteins, fats and carbohydrates, while assisting with controlling your mood as well as your behavior. Pyridoxine might also be of benefit for children with learning difficulties, as well as assisting in the prevention of dandruff, eczema and psoriasis.

It assists in the balancing of sodium and potassium as well promotes red blood cell production. It is further involved in the nucleic acids RNA as well as DNA. It is further linked to cancer immunity and fights the formation of the toxic chemical homocysteine, which is detrimental to the heart muscle.

Women in particular may suffer from pre-menstrual fluid retention, severe period pains, emotional PMS symptoms, premenstrual acne and nausea in early pregnancy. Mood swings, depression as well as loss of sexual drive is sometimes noted when pyridoxine is in short supply and the person is on hormone replacement therapy or on birth control pills.

Deficiency of vitamin B6:
Irritability, nervousness and insomnia as well as general weakness, skin changes such as dermatitis and acne as well asthma and allergies might develop when pyridoxine is in short supply. Symptoms may include nails that are ridged, an inflamed tongue as well as changes to your bones - which can include osteoporosis and arthritis. Kidney stones may also appear.

Vitamin B6 deficiency symptoms will be very much like those of B2 and B3. Vitamin B6 is needed by the body to manufacture its own B3 vitamin.

Dosage:
The dosage underneath is the Recommended Dietary Allowance (RDA), but be aware that this dosage is the minimum that you require per day, to ward off serious deficiency of this particular nutrient. In the therapeutic use of this nutrient, the dosage is usually increased considerably, but the toxicity level must be kept in mind.

Males 2 mg per day and females 2 mg per day.

Best used with:
Pyridoxine should be taken together with the entire B group vitamins, and in supplementation the quantity of B6 should be nearly the same as B2, as the B 2 is needed to activate the Pyridoxine.

Vitamin C is a good partner in nutrition and magnesium, sodium, potassium, zinc, linoleic acid and fatty acids make good running mates.

When more may be required:
Should you be taking antidepressants, contraceptive pills or be on hormone replacement therapy you may need more of this vitamin. As this vitamin is readily lost in the urine, it must be taken regularly to ensure an adequate amount in the body.
