Vitamin D or vitamin Antirachitic

Friday, July 16th, 2010

Vitamin D is also called calciferol or vitamin Antirachitic. It is a fat soluble vitamin which means it is soluble in fat. Its role is to stimulate intestinal absorption of calcium and phosphorus.

Vitamin D which I will talk more specifically called vitamin D3 or cholecalciferol. It is synthesized in the skin by the action of ultraviolet (290-315 nm) cholesterol. It is also present in foods of animal origin such as fish oils.

Risk factors for vitamin D deficiency are: latitude, skin pigmentation, exposure to light and age.

Thus we do not synthesize all the same amount of vitamin D depending on where we live in the world, according to our age and our skin color. (more…)

Benefits for the body of vitamin B6

Sunday, July 11th, 2010

Vitamin B6 occurs in three forms, pyridoxine, pyridoxal, and pyridoxamine. B6 is absorbed in the large intestine. The muscle stores approximately 75-80% of vitamin stores while phase approximately 5-10%.

B6 is required for transaminations of decarboxylation of dehydratase, reactions of side chain cleavage, and release of ammonia. Her group of aldehyde acts as a Schiff base to react with amino groups of amino acids. It basically acts to shuttle between the nitrogen compounds.

Functions

The three forms of B6 can all be converted to coenzyme PLP, which facilitates the transamination and the metabolism of proteins. PLP is essential for the degradation of glycogen, it also helps with the formation of the neurotransmitter, serotonin, in part, without protein hemoglobin (heme), nucleic acids, and lecithin. Vitamin B6 is essential for the metabolism of tryptophan to niacin. (more…)

The many B’s

Thursday, January 7th, 2010

vitaminMany B vitamins, B-3 (niacin), B-6, B-9 (folic acid) and B-12, have been associated for years with better heart health. These vitamins can become even more important if it is determined the role of homocysteine.
Homocysteine is an amino acid that is found naturally in the body. Elevated levels of homocysteine in blood are associated with increased risk of heart disease, cerebrovascular attack and peripheral vascular disease. A higher level of homocysteine in blood, the greater risk. Several vitamins, particularly B-6, B-12 and folic acid can reduce blood levels of homocysteine. What is not currently known, however, is whether taking these vitamins reduces the risk of heart disease.

Vitamin B-3 (niacin)
Sometimes doctors prescribe high doses of niacin to help people improve fat levels in their blood. Niacin can:
Lowering LDL cholesterol.
Raise HDL cholesterol or high density lipoprotein. HDL cholesterol is often called “good” cholesterol because it can remove cholesterol deposits from artery walls and can send it to the liver for disposal.
To achieve these effects, niacin should be taken in doses greater than 1,000 mg per day. At these doses, niacin is considered a medication, not a supplement, and should only be taken under the advice of your doctor. High doses of niacin can be toxic. Side effects include headaches, cramps, nausea, itching, liver damage, gastrointestinal disorders, high blood sugar and irregular heartbeat. Blood tests are needed to monitor the results of regular niacin. (more…)
