Why Your Blood Needs Vitamin B6 (Pyridoxine)

Why Your Blood Needs Vitamin B6 (Find Out Here)

Our bodies depend on vitamin B6 to produce red blood cells. Vitamin B6 is also needed for the normal functioning of the brain, heart, kidneys and muscles.

It is a vital nutrient that helps prevent many chronic health problems including anemia, depression, heart disease, high blood pressure and even diabetes.

Did you know that vitamin B6 is critical to helping your body produce energy, make DNA and other cell components, and keep your nervous system running smoothly?.

In this article, we’ll talk about some of the reasons why your blood might depend on getting enough of this vital nutrient.

What is vitamin B6 and what does it do?

Vitamin B6, usually referred to as pyridoxine, is required for the synthesis of neurotransmitters serotonin and norepinephrine, and for myelin formation.

Pyridoxine deficiency in adults principally affects the peripheral nerves, skin, mucous membranes, and the blood cell system.

Vitamin B6 is a water-soluble vitamin. There are three different natural forms of vitamin B6:
pyridoxine, pyridoxamine, and pyridoxal, all of which are normally present in foods.

Pyridoxine is a form of vitamin B6 dietary supplement that is used to treat pyridoxine deficiency and sideroblastic anemia.

A dietary intake of vitamin B6
contributes to:

  • Protein and glycogen metabolism
  • Normal function of the nervous system
  • Red blood cell formation
  • Immune function
  • The regulation of hormonal activity
  • Homocysteine metabolism
  • Energy-yielding metabolism
  • Cysteine synthesis
  • Psychological functions

Is vitamin B6 good for your blood?

Yes. Sufficient intakes of foods and dietary supplements containing vitamin B6 is good for your body. Here are the reasons why your blood needs vitamin B6.

Heart disease

Several observations have suggested that low dietary intake of vitamin B6 leads to higher risk of heart disease.

In addition, vitamin B6 has been shown to play a role in lowering blood levels of homocysteine; high levels of this amino acid appears to be linked with heart disease, but it is not clear whether lowering levels of homocysteine will reduce the risk of heart disease.

Immune function

Studies indicate that an adequate vitamin B6 intake is especially important in the elderly, as this
group often suffers from impaired immune function.

The amount of vitamin B6 required to improve the immune system has been shown to be higher than the current recommended intake.

Cognitive function

Because of mixed study findings, it is presently unclear whether supplementation with vitamin B6
and other B vitamins might lessen age-related cognitive decline.

Kidney stones

Some study findings suggest that increased intake of vitamin B6 might decrease the risk of developing kidney stones, while other trials have not shown such relationship.

What foods provide vitamin B6?

Vitamin B6 is found naturally in many foods and is added to other processed foods. You can get recommended amounts of vitamin B6 by eating:

  • Cereal grains
  • Fish
  • Legumes
  • Spinach
