The shortlist

Every supplement we rate

What the research supports, what the dose actually is, and who each one genuinely suits.

Our method

How we review

We have not used these products and we never pretend we have. We read the specs, the certifications and thousands of owner reports, so you do not have to.

🧪

Start with the evidence

We look up what trials exist for the ingredient, and how strong they really are.

⚖️

Check the dose

A studied ingredient at a token dose does nothing. We compare the label to the research.

🔍

Look for third-party testing

Purity and label accuracy vary wildly. We note who tests independently and who does not.

💷

Work out cost per serving

The tub price hides the real number. We calculate what a month actually costs.

Why trust us

We answer to readers, not brands

  • No brand deals. Nobody pays for a place on this list or a kinder verdict.
  • Doses, not buzzwords. An ingredient only counts if the amount matches what was studied.
  • We say when it does nothing. Plenty of popular supplements have thin evidence, and we write that down.
  • Not medical advice. We point at the research. Your GP knows your history and we do not.

Supplement questions, answered

Do any supplements actually work?

A small number have genuinely solid evidence behind them, creatine and vitamin D among them. Most of the rest sit somewhere between promising and unproven, and a fair few do nothing at all. We tell you which group a product falls into rather than selling the whole shelf.

Why is the dose such a big deal?

Because a label can list an impressive ingredient and include a fraction of the amount that was studied. It is the single most common trick in this industry, so every review compares what is in the tub with what the research actually used.

What does third-party tested mean?

It means an independent lab has checked that the contents match the label and that nothing unwanted came along. Supplements are loosely regulated, so this matters more here than in almost any other category we cover.

Is the expensive one better?

Often not. Price tends to track marketing spend rather than quality, and some of the best value products are unglamorous. We work out cost per serving so you can see what you are really paying.

Should I speak to a doctor first?

Yes, particularly if you take prescription medication or have an ongoing condition. Interactions are real. Our reviews help you choose well, but they are not a substitute for someone who knows your medical history.

The team

The people behind the reviews

A small, slightly obsessive crew who'd rather read a spec sheet than a press release.

RO

Rachel Okonjo

Lead reviewer

Spent six years in nutrition research and now spends it reading labels that hope nobody will.

TW

Tom Whitfield

Evidence editor

Traces every health claim back to the trial it came from, and checks the trial was any good.

AR

Aisha Rahman

Purity and labelling

Follows third-party test results and recalls so a contaminated batch does not stay on our list.
