Vitamin B1 vs. Vitamin B12: What's the Difference?
Edited by Janet White || By Harlon Moss || Published on February 16, 2024
Vitamin B1 (Thiamine) plays a key role in energy metabolism and nerve function, while Vitamin B12 (Cobalamin) is essential for red blood cell formation and brain health.
Key Differences
Vitamin B1, also known as thiamine, is crucial for carbohydrate metabolism and neural function. Vitamin B12, or cobalamin, is vital for neurological function, DNA synthesis, and red blood cell formation.
Vitamin B1 is found in foods like whole grains, nuts, and meats. A deficiency can lead to conditions like beriberi and Wernicke-Korsakoff syndrome. Vitamin B12 sources include animal products and fortified foods, with deficiencies leading to anemia and neurological disorders.
The body's absorption of Vitamin B1 happens in the small intestine and is rapidly metabolized. Vitamin B12 absorption is more complex, requiring intrinsic factor and is stored in the liver.
Vitamin B1 is water-soluble and not stored in large amounts in the body, making regular intake necessary. Vitamin B12 is also water-soluble but can be stored in the body for years.
Vitamin B1 is involved in the function of several enzymes that help produce energy from carbohydrates. Vitamin B12 works closely with folate and is necessary for the production of DNA and the health of nerve cells.
