Vitamin B12 has many uses in the body and especially affects the nervous system.
It is known to cause mental retardation in developing children who are deficient in this vitamin. But does it affect the mental acuity of adults? A recent study suggests that vitamin B12 deficiency may be partly responsible for poor cognition in the elderly. Here is an article from Health Day about the study: http://consumer.healthday.com/Article.asp?AID=657177
Most people eat enough animal products to get the needed vitamin B12, but B12 is very difficult to absorb.
Acid is required in the stomach to absorb not only vitamin B12, but proteins and many other nutrients as well. The problem in acid reflux is not acid, but reflux!! The best way to prevent and even treat B12 deficiency is to improve the digestive system. One of the worst things you can do for the digestive system is take antacids.
So work on getting off of your antacids and improving your digestive health. I will have more posts on digestive health in the coming weeks.
