Vitamin B12, also known as cobalamin, is a water-soluble vitamin essential for red blood cell formation, nerve function, and DNA synthesis. It is naturally found in animal products such as meat, fish, poultry, eggs, and dairy. Some fortified foods, like certain breakfast cereals and nutritional yeasts, also provide vitamin B12. The recommended daily intake for adults is 2.4 micrograms. Deficiency can lead to anemia, fatigue, muscle weakness, nerve damage, and mood disturbances. Individuals at risk include older adults, those with digestive disorders affecting nutrient absorption, and people following vegetarian or vegan diets. Vitamin B12 supplements are generally considered safe when taken at appropriate doses. However, high doses may cause side effects such as headache, nausea, vomiting, diarrhea, fatigue, or tingling sensations in the hands and feet. Certain medications, including metformin and proton pump inhibitors, can interfere with vitamin B12 absorption. It's important to consult a healthcare provider to determine the need for supplementation and to address potential interactions with other medications.
