Vitamin B12, also known as cobalamin, is a vital nutrient that plays a pivotal role in maintaining overall health. It's essential for red blood cell production, DNA synthesis, and nerve function. A deficiency in vitamin B12 can lead to anemia, fatigue, neurological issues, and even irreversible nerve damage.
Many people, especially vegetarians and vegans, are at risk of B12 deficiency because it is primarily found in animal-based foods. Additionally, age-related declines in B12 absorption can affect older adults. Thus, taking B12 supplements or consuming fortified foods is crucial to ensure adequate intake. Proper B12 levels are essential for sustained energy, cognitive function, and overall well-being.
