The Role of Diet
Most people get enough vitamin B12 and folate from a balanced diet, but vegans and vegetarians may need supplements since plant foods lack vitamin B12. Folate is abundant in leafy greens and fortified grains, making deficiency rare with a diverse diet.
Understanding Absorption
Vitamin B12 absorption is complex, involving several steps from the stomach to the intestine. Issues like pernicious anemia or medications can disrupt this process. Folate absorption occurs mostly in the small intestine and can be affected by intestinal disorders.
Common Causes of Deficiencies
Vitamin B12 deficiency often results from poor absorption due to conditions like pernicious anemia or long-term use of certain medications. Folate deficiency is less common but can occur with poor diet or absorption issues, especially in people with increased needs like pregnant women.
