Who is at risk of Vitamin B12 deficiency?
Individuals most at risk of Vitamin B12 deficiency include older adults, people with digestive disorders such as Crohn’s disease or celiac disease, vegans, vegetarians, and those who have undergone weight-loss or gastrointestinal surgeries. Limited dietary intake or absorption challenges are common contributors.
How can Vitamin B12 deficiency be diagnosed?

What are the health benefits of maintaining adequate Vitamin B12 levels?
Adequate Vitamin B12 levels support energy production, healthy brain function, and red blood cell formation. It also helps prevent anemia, reduces the risk of birth defects during pregnancy, and promotes better cardiovascular health by regulating homocysteine levels.
Can you get too much Vitamin B12?
