Vitamin B12, also known as cobalamin, is a water-soluble vitamin that plays a crucial role in the normal functioning of the brain and nervous system, as well as the formation of red blood cells. It is one of the eight B vitamins and is essential for maintaining good health. In this blog post, we will explore the benefits of B12, sources of the vitamin, recommended daily intake, and potential risks of deficiency.
Benefits of B12:
Helps Maintain Nervous System Functioning: Vitamin B12 plays a key role in the normal functioning of the nervous system, including the brain and spinal cord. It also helps in the formation of myelin, which is a protective sheath that covers nerve fibers, allowing them to transmit messages more efficiently.

- Supports Red Blood Cell Formation: Vitamin B12 is required for the formation of red blood cells. Without enough B12, the body produces abnormally large and immature red blood cells, which can lead to anemia.
- Boosts Energy: Vitamin B12 helps convert food into energy by aiding in the metabolism of carbohydrates, proteins, and fats. As a result, it is often used as an energy booster.
- May Improve Mood: Vitamin B12 may have a positive effect on mood by reducing symptoms of depression and anxiety. It has been suggested that B12 may increase the production of serotonin, a neurotransmitter that helps regulate mood.
Sources of B12:
Vitamin B12 is naturally found in animal products such as meat, fish, poultry, eggs, and dairy products. It is not found in plant foods, which makes it particularly challenging for vegetarians and vegans to obtain enough B12 from their diet alone. However, some plant-based foods are fortified with B12, including breakfast cereals, plant-based milks, and nutritional yeast.
Recommended Daily Intake:
The recommended daily intake of vitamin B12 for adults is 2.4 micrograms (mcg) per day. Pregnant and breastfeeding women may require higher amounts. The amount of B12 that is absorbed by the body can vary depending on age, gender, and other factors. Therefore, it is recommended that people who follow a vegetarian or vegan diet or those over the age of 50 consider taking a B12 supplement or getting regular B12 injections.
Potential Risks of Deficiency:
A deficiency in vitamin B12 can cause a range of symptoms, including fatigue, weakness, tingling or numbness in the hands and feet, difficulty walking, and even dementia. Over time, a deficiency can lead to irreversible nerve damage. Vegans and vegetarians are at higher risk of B12 deficiency, as are older adults, those with gastrointestinal disorders, and those who have had gastrointestinal surgery.
In conclusion, vitamin B12 is an essential nutrient that is necessary for many bodily functions, including the formation of red blood cells and the normal functioning of the nervous system. It is important to include sources of B12 in your diet or consider taking a supplement to avoid deficiency and the associated health risks. If you are concerned about your B12 intake, speak with your healthcare provider who can advise you on the best course of action.
