Vitamin B12

What Is B12?

Vitamin B12, or cobalamin, is a vital water-soluble vitamin that plays a key role in maintaining energy levels, neurological health, red blood cell formation, and DNA synthesis. It is naturally present in animal-based foods such as meat, poultry, eggs, and dairy. What sets B12 apart from other B vitamins is its ability to be stored in the liver for extended periods. However, as we age or face digestive challenges, the body’s ability to absorb B12 can decline—leading to symptoms like fatigue, memory problems, mood disturbances, and even long-term cognitive decline if left unaddressed. At the cellular level, Vitamin B12 supports mitochondrial function, aiding in the conversion of food into usable energy. It acts as a coenzyme in crucial metabolic processes that help generate ATP—the body’s primary energy currency. This makes B12 especially important for active individuals, older adults, and anyone looking to support their physical and mental stamina throughout the day.

Another essential function of Vitamin B12 is its role in maintaining the myelin sheath—the protective coating around nerves that ensures smooth and fast communication between the brain and the rest of the body. When B12 levels are low, nerve signaling can become compromised, resulting in numbness, tingling, cognitive fog, or poor coordination. This neuroprotective role is a major reason why B12 is commonly included in supplements targeting cognitive support and nervous system resilience. Vitamin B12 is also central to red blood cell formation and DNA replication. It helps ensure the production of healthy, oxygen-carrying red blood cells and supports tissue repair and renewal. A deficiency in B12 can lead to megaloblastic anemia, a condition where red blood cells are too large and inefficient—leading to symptoms like weakness, dizziness, and reduced endurance. These effects can significantly affect quality of life, particularly in older populations or those with restricted diets.

For individuals following vegan or vegetarian diets, B12 supplementation is especially important, as plant-based foods do not naturally contain this nutrient. Even for those who consume animal products, factors like low stomach acid, medications that affect absorption (e.g., metformin or antacids), or gastrointestinal disorders (such as celiac or Crohn’s disease) can interfere with the body’s ability to utilize B12 from food sources. Vitamin B12 is available in various forms, including methylcobalamin, cyanocobalamin, and adenosylcobalamin. Among these, methylcobalamin is considered the most bioactive and is preferred for its superior absorption and support for brain and nerve function. It can be taken in capsules, sublingual tablets, or even by injection depending on individual needs.
