Vitamin B12, also known as cobalamin, is a water-soluble vitamin that is crucial for various bodily functions. It is essential for the metabolism of every cell in the human body, including the formation of red blood cells and the maintenance of the nervous system¹². Vitamin B12 is naturally found in animal products such as fish, meat, poultry, eggs, milk, and dairy³.

Benefits of Vitamin B12:

1. Red Blood Cell Formation: Vitamin B12 is important for the production of red blood cells. A deficiency in Vitamin B12 can lead to anemia, which is characterized by fatigue and weakness⁴.

2. Neurological Function: It is vital for the maintenance of the protective covering that surrounds nerve fibers and is essential for the proper functioning of the brain and nervous system⁵.

3. DNA Synthesis: Vitamin B12 plays a critical role in the synthesis of DNA, which is necessary for cell division and growth⁶.

4. Energy Production: By assisting in the conversion of food into glucose, which is used for energy, Vitamin B12 contributes to the body's overall energy production⁷.

5. Heart Health: Vitamin B12 is involved in the breakdown of homocysteine, a protein linked to an increased risk of heart disease. However, while B12 supplementation can lower homocysteine levels, its effect on reducing cardiovascular events remains uncertain⁸.

Deficiency in Vitamin B12 is more common among individuals over 50, those who follow a vegetarian or vegan diet, and individuals with certain digestive system conditions or who have undergone weight loss surgery⁹. Symptoms of deficiency can include anemia, difficulty maintaining balance, numbness or tingling in limbs, weakness, and cognitive disturbances, such as dementia¹⁰.
