Vitamin B12

Vitamin B12 is an essential nutrient that your body can’t make on its own, so you need to get it from your diet or supplements. Vitamin B12 is required for proper red blood cell formation, neurological function, and DNA synthesis. Vitamin B12 is naturally found in animal foods, including meats, fish, poultry, eggs and dairy. However, it can also be found in products fortified with B12, such as some varieties of bread and plant- based milk.

Vitamin B-12 deficiency occurs when the body does not receive enough vitamin B-12. It can result in irreversible and potentially severe damage, especially to the nervous system and brain. Even slightly lower-than-normal levels of vitamin B-12 can trigger deficiency symptoms, such as depression, confusion, memory problems, and fatigue. Other symptoms of vitamin B- 12 deficiency include constipation, loss of appetite, and weight loss.
