ADVERTORIAL: Why most health claims you see are misleading

ADVERTORIAL

By Andrea Doolan, CEO, Atlantia Clinical Trials, Cork

If you walk down any supermarket aisle or into any health supplement store today, you'll be surrounded by products claiming to be ‘clinically proven’, ‘scientifically backed’, or designed to ‘support gut health’.

Most consumers understandably assume these phrases mean a product has been rigorously tested and proven to work. In reality, they often mean far less than people think. Take ‘clinically proven’. It sounds impressive, but on its own, it tells you very little. Proven in twenty people or two thousand? Over a few weeks or several years? Against a placebo, or not at all? The phrase may be legally permissible, but this does not necessarily make it meaningful.

There is also a significant difference between a study and strong evidence. One positive study is a starting point, not a conclusion. Scientific confidence comes from multiple high-quality studies producing consistent results across different populations. A company may be able to point to a single trial and describe its product as ‘research-backed’, but that does not automatically mean the evidence is robust.

Marketing language is extraordinarily good at borrowing the credibility of science without carrying its rigour. Phrases like ‘may support’ or 'helps maintain' are carefully chosen to imply a benefit that has not been definitively established.

Research shows that when people see phrases like ‘supports heart health’, many assume the product prevents heart disease, even when that’s not what the claim legally means.

Consumers like you and me read these as promises, but the regulators read them very differently. The question I always ask is simple: what did they actually test, and does that match the claim being made?

A study on a specific strain of probiotic or a health supplement at a particular dose does not validate a completely different product making a similar-sounding promise. Context matters enormously, and it rarely makes it onto the label.

Unlike medicines, many supplements do not require pre-approval before reaching the market, which places more responsibility on consumers to evaluate claims carefully. So how do you, as a consumer, cut through this? Look for specificity.

Vague claims are a warning sign.

Look at how much of the ingredient was tested, how long the study lasted, and how many people took part.

If a brand will not tell you where to find the underlying research, ask yourself should I even be buying this?

This is precisely why Atlantia came into existence. We were founded in Cork, out of UCC, and what began as a small team has grown into a global operation conducting clinical trials across some of the world's most prominent markets.

Today, we operate from two key locations, Cork and Chicago, working with leading companies across Europe, North America, and beyond. Our mission has not changed since day one: turn genuine scientific questions into evidence that actually holds up under scrutiny. The work is rigorous, slow, and sometimes inconvenient. The world does not need more marketing dressed as science. It needs fewer shortcuts and more honesty.

Consumers deserve better. Increasingly, they are starting to demand it.
