How much B12 do I need?

Vitamin B12 is essential for energy, brain function, and red blood cell production—but how much should you take?

It depends on your diet, age, and health status.

Everyday Health (0–500µg/day)
If you eat a balanced diet with some B12 sources and have no absorption issues, the recommended daily intake is 2.4µg (RDI).

Since absorption varies, many take 10–500µg/day for general health and energy.

Best for: Omnivores, those who eat some B12-fortified foods, and young adults with no absorption concerns.
Vegans & Over 50s (500–1000µg/day)
B12 is mostly found in animal products, making plant-based eaters more prone to deficiency. As we age, stomach acid levels drop, reducing B12 absorption.

Best for: Vegans, vegetarians, and anyone over 50 who needs extra B12 support.
B12 Deficiency Recovery (1000–3000µg/day)
If a blood test confirms low B12, short-term high doses (1000–3000µg/day) are often recommended to restore levels quickly.

Once levels stabilize, most people switch back to a maintenance dose (500µg or less per day).

Best for: Those diagnosed with low B12, experiencing symptoms, or following a doctor’s advice.
Medical Conditions & Megadosing (3000–5000µg+ per day)
Those with medical conditions affecting B12 absorption (e.g., pernicious anemia, Crohn’s disease, gastric bypass) may require higher doses under medical supervision.

Best for: Anyone with a diagnosed absorption issue—consult a healthcare professional.
Monitoring Your B12 Levels
For the most accurate advice, consult a health professional. A blood test is the best way to check your B12 levels.
