Five everyday supplements, and what they actually do

Walk down any supplement aisle and the promises come thick and fast. The honest truth is quieter. Supplements are not magic, and they do not replace real food, decent sleep, or a bit of sun. What they can do is help fill a gap when your diet or your routine leaves one. Here is a plain look at five of the most common ones, and where they genuinely earn their place.

Vitamin C
Best known for immune support, vitamin C also helps your body absorb iron from food and plays a part in keeping skin and tissue healthy. Most people get enough from fruit and vegetables, but a supplement can help when your meals are short on fresh produce or you feel run down.

Vitamin D
This one is worth singling out. Your body makes vitamin D from sunlight, so people who spend most of the day indoors, stay covered up, or work nights often run low. It supports healthy bones, muscles, and the immune system, which makes it one of the more sensible supplements to consider through the year.

Omega-3
Found naturally in oily fish, omega-3 fatty acids support heart and brain health. If fish rarely makes it onto your plate, a fish oil supplement is a simple way to top up. Look for one that lists its EPA and DHA content, since those are the parts doing the work.

Zinc
Zinc plays a role in immune defence, wound healing, and even taste and smell. It tends to matter most when you are recovering or when your diet is limited. It is not something to take in large amounts without a reason, so stick to sensible, labelled doses.

A daily multivitamin
Think of this as a safety net, not a cure-all. A once-a-day multivitamin can cover the small gaps in an otherwise reasonable diet. It will not fix poor eating, but it can steady things when life gets busy and meals get skipped.

Doing this safely
A few honest rules. Food comes first, and more is not better, since some vitamins and minerals cause problems in excess. If you are pregnant, breastfeeding, managing a health condition, or taking regular medication, check with a pharmacist or doctor before starting anything new, because some supplements interact with medicines. And if you are not sure what, if anything, you actually need, ask us. We would rather point you to the right one than sell you the whole shelf.
