Vitamin B12 injections in Basingstoke — £45

Why B12?

Vitamin B12 is essential for energy production, healthy nerves and red blood cells. When levels run low — which is common, especially as we get older or on plant-based diets — the result is persistent tiredness, low energy and brain fog that diet alone often struggles to fix.

A B12 injection delivers the vitamin directly, so it’s absorbed properly and you feel the benefit within days, not weeks.

What it treats

• Low B12 from diet — vegan and vegetarian diets often need support.
• Absorption issues — tablets don't always raise B12 where injection does.
• Fatigue and low energy — where a blood result or diet history suggests a role.
• General wellbeing support — as part of a wider health picture.

Who it’s for

• Persistent tiredness or low energy that rest doesn’t seem to fix
• Fatigue and brain fog
• Plant-based or vegetarian diets, which are commonly low in B12
• Age-related absorption — B12 absorption naturally declines with age

What to expect

A quick, straightforward injection — usually into the upper arm or buttock — taking a couple of minutes. We’ll ask a few questions first to make sure it’s appropriate for you, and advise on how often to repeat it based on how you respond.

B12 pairs naturally with skin health — low energy often coincides with skin that looks dull or tired. If that’s part of the picture, the skin boosters range and polynucleotides work on the skin-quality side while B12 works on the energy side. Our under-eye polynucleotides guide covers the tired-eyes question honestly. New to B12? Read the who-actually-needs-one guide first.

The evidence

Vitamin B12 injections are a clinical treatment with a clear evidence line: intramuscular B12 is the standard, guideline-endorsed treatment for confirmed B12 deficiency, restoring levels and resolving deficiency symptoms — the evidence there is not in dispute. What the research is honest about: for people with normal B12 levels, there's no good evidence that extra B12 improves energy, fatigue or wellbeing — the “energy boost” effect reported by many patients isn't supported by controlled trials in B12-replete people. We check the picture with you first, because treatment is most useful where a deficiency or dietary gap is real.
