Vitamin B12, also known as cobalamin, is a water-soluble vitamin that plays a key role in the production of red blood cells and the maintenance of a healthy nervous system. One of its primary functions is to assist in the conversion of food into usable energy, making it an indispensable nutrient for our body’s metabolic processes.
The recommended dietary allowance (RDA) of vitamin B12 for adults is 2.4 micrograms (mcg) per day. However, some people may need more or less depending on their age, health status and dietary intake. For example, pregnant and breastfeeding women need 2.6 and 2.8 mcg per day, respectively, while older adults and people with certain medical conditions may have trouble absorbing vitamin B12 from food and may require supplements or injections.

Benefits of Vitamin B12
Elevated Energy Levels: Vitamin B12 aids in the production of red blood cells, which transport oxygen to body tissues. This process is crucial for maintaining energy levels, preventing fatigue, and supporting overall vitality.
Neurological Health: The vitamin is essential for the synthesis of myelin, a protective sheath around nerve fibers. This helps maintain the health of our nervous system, promoting proper brain function, and reducing the risk of neurological disorders.
Mood Regulation: Vitamin B12 is linked to the production of serotonin, a neurotransmitter that regulates mood. Adequate levels of B12 may contribute to a balanced mood and help prevent symptoms of depression and anxiety.
Heart Health: Vitamin B12 works alongside other B vitamins to regulate homocysteine levels. Elevated homocysteine is associated with an increased risk of heart disease, making B12 crucial for maintaining cardiovascular health.
