Vitamin B12 injection

B12 deficiency causes fatigue, brain fog, and nerve symptoms, and it is common in older adults, vegetarians, and anyone on long-term metformin or acid-reducing medication. An injection restores levels reliably where tablets often do not.

What's Involved

Level testing — Blood testing to confirm deficiency before treatment begins.
Injection schedule — A loading course followed by maintenance intervals suited to the cause.
Cause review — Investigating why the level is low rather than treating it indefinitely.

When to Come In

Unexplained tiredness — Fatigue with no other clear explanation.
Tingling or numbness — Nerve symptoms in the hands or feet.
Risk factors — Vegetarian or vegan diet, metformin, PPIs, or age over sixty.
