Benefits Of Vitamin B12
By Josh Riverside
Vitamin B-12 is a safe, reliable and inexpensive vitamin. For health-conscious individuals, a regular intake of a prescribed amount of vitamin B-12 is a key element for preserving a balance in the human body. B-12 could be obtained from food sources or could be taken in the form of supplements orally or via injections.
In combination with other B-group vitamins, vitamin B-12 ensures the smooth functioning of vital life processes of the human body. It is important for maintaining a healthy nervous system and DNA production. Vitamin B-12 helps to regulate the formation of red blood cells in the body. Other benefits of vitamin B-12 include its role in maintaining and increasing energy levels in the human body.
Vitamin B-12 is highly beneficial in various forms. Methylcobalamin, the coenzyme form of vitamin B-12 is a body-friendly version, which means that no metabolic steps are required for its ingestion, and it can be used it in its normal form. It is available as a sublingual tablet that dissolves under the tongue (because the digestive system might modify this molecule). Through this method, vitamin B-12 can directly penetrate the bloodstream and yield numerous benefits. Hydroxocobalamin is another form of vitamin B-12 that has been recognized as an effective cure for cyanide poisoning.
Research studies reveal a clear, inverse correlation between homocysteine (an amino acid found in the human body) levels and vitamin B-12 levels. Blocking the formation of homocysteine leads to endothelial dysfunction (a narrowing of the arteries) and is a precursor of atherosclerosis; vitamin B-12 helps to curb atherosclerosis. A supplement of vitamin B-12 also augments the efficiency of folic acid’s capacity to lower homocysteine levels. Researchers are of the opinion that in conjunction with folic acid, an adequate dose of vitamin B-12 helps to counter heart diseases and thrombosis. The synthesis of S-adenosylmethionine (SAMe), a compound involved in immune function and mood, depends on the association of folate and vitamin B-12.
Studies indicate that absorption of vitamin B-12 ecreases with an increase in age. Hence, an increased intake of vitamin B-12 is extremely useful for adults above fifty. The recommended form of intake is in supplement form, since elderly people absorb this form better than food forms of vitamin B-12. A supplementation of vitamin B-12 aids in the cognitive function and heals neurological impairment within this group.
In most cases, vitamin B-12 should be taken in conjunction with a folic acid supplement and a B-complex vitamin. The good news is that while an intake of vitamin B-12 facilitates functions necessary for everyday existence, an extra dose causes no harm but instead could be stored for future use.
