IV vitamin drips: what to know before you book one

IV vitamin therapy is heavily marketed and the claims made for it are often well ahead of the evidence. We offer it, so we have an interest here - which is exactly why this is written the way it is. If you are considering a drip, these are the things worth knowing first.

What a drip is good at

Delivering fluid and nutrients directly into the bloodstream, bypassing the gut. That is genuinely useful in specific situations - most clearly where someone cannot absorb something adequately by mouth, or where a deficiency has been confirmed and oral replacement has not worked or is not tolerated.

The clearest example is iron. Where blood tests confirm iron deficiency and oral iron is not suitable, tolerated or effective, an iron infusion is an established treatment with real evidence behind it.

What the evidence does not support

For a healthy, well-nourished person with no deficiency, there is little good evidence that routine vitamin infusions improve energy, immunity or general wellbeing beyond what you would get from an ordinary diet. If your levels are normal, your kidneys excrete the excess of most water-soluble vitamins fairly promptly.

If a clinic tells you a drip will detoxify you, boost your immune system or cure a hangover, treat that as marketing. Your liver and kidneys do the first job continuously and for free.

Test before you treat

This is the practical point. If you are tired and run down, the useful first step is usually a blood test, not a drip. A full blood count, ferritin, thyroid function, vitamin D and B12 will identify most of the common, treatable causes - and if something does come back low, you then know what you are actually treating.

Buying a generic vitamin infusion before testing means you may be treating something you do not have, and missing something you do.

Risks worth knowing

Any cannula carries a small risk of bruising, infection or inflammation of the vein. Allergic reactions are uncommon but possible. Some ingredients are unsafe in specific conditions - people with kidney disease, heart failure or certain metabolic disorders need proper assessment before any infusion.

What to check before booking anywhere

• Is it given in a registered clinical setting, with a doctor available?
• Who inserts the cannula, and what happens if you react?
• Is there a consultation first, or does it go straight to treatment?
• Will they test before they treat, or sell a drip regardless?
• What exactly is in it, and at what dose?
