Vitamin B12 After 60
The essential nutrient for energy, nerve function, and cognitive health in older adults.
Why B12 Deficiency Is Common After 60
Vitamin B12 absorption declines significantly with age. The stomach produces less "intrinsic factor" — a protein necessary for B12 absorption from food. Additionally, many older adults take acid-reducing medications (PPIs, H2 blockers) that further impair B12 absorption. As a result, B12 deficiency affects an estimated 10–30% of adults over 60.
What Vitamin B12 Does
- Energy production — B12 is essential for converting food into usable energy at the cellular level
- Nerve function — Maintains the protective myelin sheath around nerve fibers
- Red blood cell production — B12 deficiency causes megaloblastic anemia, leading to extreme fatigue
- DNA synthesis — Critical for cell division and repair
- Cognitive health — Deficiency is linked to memory problems, confusion, and increased dementia risk
⚠️ Signs of B12 Deficiency
- Extreme, persistent fatigue
- Weakness and lightheadedness
- Tingling or numbness in hands and feet
- Memory problems and difficulty concentrating
- Pale or yellowish skin
- Mood changes or depression
🥩 Food Sources of B12
B12 is found almost exclusively in animal products: meat, fish, poultry, eggs, and dairy. If you follow a vegetarian or vegan diet, supplementation is essential.
Important: B12 deficiency can develop slowly over years and is often missed. Ask your doctor to check your B12 level with a simple blood test.
