Walk into any pharmacy and the supplements aisle is overwhelming. Everyone seems to be taking something, and the marketing promises a lot. So what do you actually need? The honest truth is that most people need far fewer of them than the industry would have you believe, and food comes first.
In this guide we cut through the noise on supplements, from vitamins to protein, explain why your diet and nutrition matter most, and point you to the right person to ask.
Do You Actually Need Supplements?
For most healthy people eating a reasonably balanced diet, the answer is: probably fewer than you think. Supplements are meant to supplement, to fill genuine gaps, not to replace good food. Some people do have real needs, but blanket use just in case is usually money down the drain. The starting question is always whether you have an actual gap to fill.
Food and Diet First
Here is the truth the industry glosses over: a good diet does most of the heavy lifting. Whole foods provide vitamins, minerals, protein and fibre in forms your body uses well, alongside benefits no pill can replicate. Getting your nutrition right, eating enough protein, plenty of plants and a variety of whole foods, matters far more than any product. Fix the diet first.
Where Supplements Can Help
That said, they do have their place. Genuine deficiencies, certain life stages, specific health conditions, restricted diets and some athletic goals can all be reasons a particular one makes sense. The key word is specific. A targeted product for an identified need is very different from a cupboard full of things bought on hope. Individual advice is what separates the two.
The Marketing Trap
The supplements industry is enormous and largely built on marketing, not evidence. Impressive claims, athlete endorsements and fear of missing out sell a lot of product that does very little. Be sceptical of anything promising dramatic results, detoxes or cure-alls. If it sounds too good to be true, it almost always is. Evidence, not hype, should guide your choices.
Quality, Safety and Regulation
Not all products are created equal. Quality, dosing and purity vary widely, and supplements are regulated differently from medicines. Some can interact with medications or be unsafe in high doses, so more is not better. This is another reason to involve a professional rather than self-prescribing based on a social media post.
Who to Ask About Supplements
This is the most important point. For personalised advice, speak to your GP, a pharmacist or an accredited dietitian. They can check for genuine needs, consider your health and medications, and recommend what is actually worth taking, if anything. As physiotherapists, our focus is your movement and rehabilitation, and we are always happy to point you to the right expert for nutrition.
Common Questions About Supplements
Do I really need supplements?
Most healthy people eating a balanced diet need few if any. They fill genuine gaps rather than replace good food, so it depends on your individual needs.
Can supplements replace a good diet?
No. A good diet provides nutrients in forms and combinations no pill can match. Nutrition comes first, with products filling specific gaps only.
Are more vitamins better?
No. Beyond your needs, extra vitamins offer no benefit and some can be harmful in high doses. More is not better here.
Are supplements regulated?
They are regulated differently from medicines, and quality varies. This is why choosing reputable products and getting professional advice matters.
Who should I ask?
Your GP, a pharmacist or an accredited dietitian are the right people for personalised, evidence-based advice on supplements.
