While the naturally occurs as a mixture of 3 forms, in the body, pyridoxine is converted into its active derivatives.

Sources of vitamin B6 in food


Part of the daily requirement for vitamin B6 is carried in the intestines through bacterial synthesis. 

However, these aren't sufficient quantities for normal functioning of metabolic processes in the body, so it is necessary to enter the amounts of vitamin B6 through food.

Vitamin C, linoleic acid and other B complex vitamins help better absorption of vitamin B6, while coffee, alcohol, and tea reduce the absorption of pyridoxine.

The role of vitamin B6 in the organism

Vitamin B6 influence the work of neurotransmitters and hormones that act on daily spirit level (serotonin and melatonin)

- Pyridoxine is the protector of the heart and blood vessels because it prevents the release of homocysteine, an amino acid that acts harmful to the health of the heart muscle.

- Vitamin B6 helps the absorption of vitamin B12, and also participates in synthesis of other vitamins from group B vitamins, namely vitamin B1.

- It has a positive effect on the excretion of excess water from the body and control of tissue fluids. 


- Vitamin B6 is also called vitamin of pregnancy, because it is essential for the growth and development of the fetus, while in women at menopause, vitamin B6 helps to relieve the symptoms of hormone imbalance
