🌱 What it is
Vitamin B12 is an essential nutrient needed by bone marrow to make healthy red blood cells and to maintain nerve tissue.
✨ Why it's good for you
- Corrects a well-defined, common nutrient deficiency
- Supports healthy nerve function
- Available in easy oral, sublingual, or injectable forms
🥄 How to use it
For confirmed B12 deficiency or pernicious anemia, a doctor may prescribe 50-100 mcg injections or high-dose methylcobalamin (around 1,000 mcg) taken orally, sublingually, or by other routes as directed. Get blood levels checked before starting a high-dose regimen.
How much: 50-100 mcg injection or 1,000 mcg methylcobalamin as directed by a healthcare provider.
Why it works: B12 replaces what's missing so bone marrow can again produce mature, healthy red blood cells, and it supports the myelin sheath that protects nerves — deficiency can otherwise cause anemia, facial nerve issues, low blood pressure, or sciatica-like nerve pain.
⚠️ Cautions
- Pernicious anemia requires a medical diagnosis (often involving intrinsic factor testing) — see a doctor rather than self-treating a suspected deficiency.
- People on a strict vegan diet, older adults, and those with absorption issues (e.g., after gastric surgery) are at higher risk and should be tested periodically.
- High-dose injections should be administered or prescribed by a healthcare provider.
