Importance of vitamin b12

In old age, it is essential to pay attention to health care and wellness. As we age, the body goes through changes that present new challenges, and one of the key elements to maintaining a good quality of life is ensuring an adequate intake of vitamin B12.

In this session, we will delve into the importance of vitamin B12 in the elderly and how to maintain optimal levels.

Introduction to vitamin B12

Vitamin B12, or cobalamin, is a water-soluble vitamin that plays a vital role in a variety of body functions. Although it is important at all stages of life, in old age it becomes even more important, as it is associated with a healthy nervous system, cognitive function, red blood cell formation and the prevention of some diseases.

Nervous system health

The nervous system is key to the proper functioning of the body and its care becomes especially important in the elderly. Vitamin B12 is crucial for the creation and maintenance of myelin, a substance that protects nerve fibers.

A lack of vitamin B12 can lead to neurological problems, such as peripheral neuropathy or motor difficulties.

Cognitive function and prevention of mental decline

Cognitive decline and neurodegenerative diseases, such as Alzheimer's and Parkinson's, are common concerns in old age. Vitamin B12 plays a role in neurotransmitter synthesis and proper brain function. Maintaining adequate levels can help prevent or delay cognitive decline and maintain optimal mental health.

Red blood cell production and prevention of anemia

Vitamin B12 is essential for the formation of red blood cells in the bone marrow. Its deficiency can cause pernicious anemia, a condition that prevents the proper production of red blood cells. This can lead to fatigue, weakness and other symptoms that impact quality of life in old age.

Sources of vitamin B12 and its absorption

Animal foods such as meat, fish, eggs and dairy are the main sources of vitamin B12. However, as we age, the body's ability to absorb this vitamin may decrease.

This reduction in absorption may be related to gastrointestinal problems, such as gastric atrophy, which affects the processing of vitamin B12. In these cases, supplementation supervised by a health professional may be necessary.
