A unique nutrient, vitamin B12 has an unusual source and a big molecule which requires a complicated process of absorption. All these may possibly contribute to deficiency which may bring about many complications. It is critical that deficiency is avoided because the benefits of vitamin B12 in human physiology can be compromised. Even if it is water-soluble and can be removed from the system by simple urination, a certain fraction is saved in organs and tissues of the body every time some amount is absorbed. It is a vitamin that plays critical role in many metabolic reactions in the human body.
1. Having erythrocytes or red blood cells which are developing normally is one of the many benefits of vitamin B12. This the reason anemia or a condition of lowered number of red blood cells sets in affecting reduced oxygen transportation to body cells whenever there is a deficiency in this vitamin.
2. To generate energy, there is a need for oxygen so that carbohydrates, fats and glucose can be transformed and processed by metabolism to release energy. Thus, vitamin B12 has been associated with boosting of energy or fatigue and lethargy in the body when there is deficiency.
3. Neuronal or nerve cell development is another one of the important functions or benefits of vitamin B12. It is common to find people with deficiency who manifests signs and symptoms similar to Alzheimer’s disease or senile dementia. Many other brain dysfunction like brain shrinking or atrophy, stress and depression can be prevented with vitamin B12 deficiency.
4. The other benefits of vitamin B12 include the protection against dreaded diseases. Some of these are high cholesterol that leads to heart diseases and hypertension, multiple sclerosis, tinnitus, diabetic neuropathy and low sperm counts.
5. Such is also important in keeping the skin, nails and hair well nurtured and healthy. This is because vitamin B12 can make regeneration and oxygenation possible.
Another benefit that is being linked to it is weight loss. There are certainly no scientific basis to think that these could be among the benefits of vitamin B12 yet many weight loss centers are already into it. In the meantime, what is important is to prevent deficiency by ensuring that vitamin B12 is loaded daily. Fortunately, supplements are inexpensive and side effects are minimal.
