Vitamin B12, Folic Acid and B6
reduce cardiovascular disease

Over thirty years ago Dr Kilmer McCully, a pathologist at Harvard Medical School, identified the link between high homocysteine levels and cardiovascular disease. His study was focused on a group of children with extremely high levels of homocysteine caused by inborn errors of metabolism. He noticed that these children had suffered conditions which are normally associated with adults – blood clots and strokes. In search for explanation Dr McCully found that there was a link between high homocysteine levels in the body and cardiovascular diseases. He also discovered a simple solution to this problem – Vitamin B12,  which proved to be effective in reduction of the number of heart attacks and strokes in people with high homocysteine levels. Unfortunately, Dr McCully’s finding was ignored at the time when a controversial hypothesis of cholesterol involvement became a big news. Thirty years later, the medical profession once again take notices of Dr McCully’s research.

How Vitamin B Therapy (B12, B6 and Folic Acid) Helps Lower Homocysteine Levels

The food we eat contains amino acids. One of which is methionine which is broken down in the body in several steps to produce homocysteine. The body utilises Folic Acid and Vitamin B12 to recycle the homocysteine back into methionine. However, those people who are deficient in either of these vitamins have a poor recycling process therefore levels of homocysteine gradually build up. High levels of homocysteine cause blood vessels to lose their elasticity that makes it harder for the blood vessels to dilate. This in turn results in damage to blood vessel linings that allows LDL cholesterol and other substances to stick to the inner lining, leading to atherosclerosis. This gives rise to a risk for stroke, heart attack and blood clots.

The cheap and easy way to lower homocysteine levels is a therapy based on daily intakes of Vitamin B12, Vitamin B6 and Folic Acid. Many doctors are aware of the Folic Acid link, but not many know the importance of Vitamin B12, which is essential to Folic Acid assimilation. Studies show that using Folic Acid alone can reduce homocysteine for some people but it does not work very well for others. Adding B12 and B6 is the solution because all three vitamins work in synergy. So if your homocysteine levels are high you should ensure that your doctor tests your Vitamin B12, B6 and Folic Acid levels. The Methylmalonic Acid (MMA) test is the most accurate for testing B12 levels.

Who is at Risk of deficiency?

The groups most at risk of Vitamin B12 deficiency are the elderly, vegans and vegetarians, those who have had gastric surgery and those who abuse drugs and alcohol. Some prescription and over the counter drugs can also lead to B12 deficiency.

Vitamin B12 is a water soluble B vitamin naturally found in fish, dairy produce, organ meats, beef, pork, nuts and seeds.

Functions of Vitamin B12:

  • Supports energy yielding metabolism
  • Supports functioning of the nervous system
  • Supports normal homocysteine metabolism
  • Supports psychological function
  • Supports red blood cell formation
  • Supports the normal function of the immune system
  • Supports the reduction of tiredness and fatigue

Vitamin B12 has a role in the process of cell division.

Folic Acid (Vit B9) is needed for the utilisation of sugar and amino acids. It is essential for the division of body cells and during pregnancy it can prevent spina bifida. Folic Acid also helps prevention of some types of tumours and heart disease.

Functions of Folic Acid (Vit B9)

  • Crucial for proper brain function
  • Plays an important role in mental and emotional health
  • Supports the production of DNA and RNA, the body’s genetic material,
  • Plays an especial role for the growth of cells and tissues during pregnancy and in infancy
  • Works closely with vitamin B12 to help make red blood cells
  • Helps iron work properly in the body

Vitamin B9 works with vitamins B6 and B12 and other nutrients to control blood levels of the amino acid homocysteine.
