Here is Vitamin B12

Vitamin B12 is necessary to each cell and system, including the blood and nerve system.
Low levels of vitamin B12 ( as well as foliate and vitamin B6 ) are linked with raised levels of homocysteine, an amino acid that, at raised levels, is connected with a raised chance of coronary disease and stroke and could also perform a part in age-implicated mental decline and dementia.
Vitamin B12 is found naturally only in foods of animal origin ; lots of other foods are buttressed with it. The body can store big amounts. Claims, alleged benefits : Vitamin B12 suppresses confusion and memory loss in older people, protects the heart, peps you up, especially when given as injections. Treats canker sores. Bottom line : many people over age 50 don't produce enough stomach acid to adequately absorb Vitamin B12.
A bad diet and heavy drinking can also make a contribution to a deficiency. Vegans ( who eat no animal products ) and people with intestinal illnesses may also be in peril. Tough Vitamin B12 deficiency may result in confusion, memory loss, shivering and weakness in the limbs, hallucinations, and listlessness.
A much rarer but more significant sort of B12 deficiency that will happen at all ages is pernicious anemia, in which the stomach just about stops manufacturing acid and a protein also needed for assimilation ( natural factor ), so that nearly no B12 from food is soaked up. Initially this can cause anemia, but ultimately, when Vitamin B12 stores are exhausted, there could be irrevocable damage caused to the nerve system.
Blood tests can diagnose a Vitamin B12 deficiency ; high amounts of B12 can correct it. Older folks need six to 15 micrograms of B12 daily ( the RDA is just 2.4 micrograms ), simply purchased from food or a multi-vitamin. Most multi marketed for seniors have 25 or thirty micrograms. Unless you have been diagnosed as deficient you don't desire additional enhancement.
