B Vitamins Deficiency has shown to be linked to several diseases and supplementation of these classes of vitamins may help most people.
Early is the discovery process of the entire field of vitamin study experts found that too little folic acid, one of the eight B vitamins, is linked to birth defects.
These include spina bifida and anencephaly and this started this change of view.
Fifty years ago no one knew what caused these birth defects, which occur when the early development of tissues that eventually become the spinal cord, the tissues that surround it, or the brain goes awry.
Understanding this deficiency was one of the advances that changed the way we view vitamins.
Over 25 years ago, researchers found that the mothers of children with spina bifida had low vitamin levels of one of the B vitamins, another one of the potential B vitamins deficiency issues.
Two large trials of random selection were conducted where women were assigned to take folic acid or a placebo.
These showed that getting too little folic acid increased a woman's chances of having a baby with spina bifida or anencephaly, and that getting enough folic acid could prevent these defects.
What is considered enough folic acid, at least 400 micrograms a day, isn't easily consumed from the food that we eat.
That's why women of child-bearing age are urged to take extra
folic acid and perhaps helping to avoid one of the deficiency
It is also why the US Food and Drug Administration now requires that folic acid be added to most enriched breads, flour, cornmeal, rice, pastas, and other grain products.
The other exciting discovery about the usage and benefits of folic acid and two other B vitamins is that they fight against heart disease and some types of cancer.
It is too early to tell if there is merely an "association" between the increased intake of folic acid and other B vitamins and heart disease or cancer, or if high intakes prevent these chronic diseases.
In the late 1960's, there was a case where two children had died from massive strokes.
The case was examined by a Boston pathologist.
Both children had inherited conditions that caused them to have high levels of a protein breakdown called "homo-cysteine" in their blood.
However that was not all as both also had arteries that where as clogged of those of a 65 year old man that was a fast food addict.
After analyzing the case, the pathologist hypothesized that high levels of homo-cysteine contribute to the artery-clogging process of atherosclerosis.
Since then, there have been several other studies that have also linked high levels of homocystenine with increased risk of heart disease and stroke, more B vitamins deficiency possibilities.
Folic acid, vitamin B6, and vitamin B12 play key roles in recycling homocystenine into methionine, one of the 20 plus building blocks from which the body builds new proteins
Without enough folic acid, vitamin B6, and vitamin B12, this recycling process becomes inefficient and homocystenine levels increase.
Several other studies have also shown that high levels of homocystenine are associated with increased risks of heart disease and strokes.
Increasing the intake of folic acid, vitamin B6, and vitamin B12 decreases homocystenine levels, all good signs of helping more B vitamins deficiency potentials.
Other studies show lower risks of cardiovascular disease among people with higher intakes of folic acid, those who use multivitamin supplements, or those with higher serum folate (the form of folic acid in the body).
In addition to recycling homocystenine, folate plays a key role in building DNA, the complex compound that forms our generic blueprint.
Observational studies have also shown that people who get higher than average amounts of folic acid from their diets or supplements have lower risks of colon cancer and breast cancer.
