What this category covers
This section explains what supplements are used for, in plain language, for readers in South Africa. Vitamins, minerals, amino acids, herbal products, protein powders and rehydration formulas all sit here, along with the products sold beside them on pharmacy and supermarket shelves.
Supplements are regulated differently from medicines. A medicine has to prove it works for a stated condition before it can make that claim. Most supplements do not clear that bar, which is why packaging tends to talk about “supporting” or “maintaining” something rather than treating it. That difference in wording is not marketing fluff — it reflects a real difference in the evidence required, and it is worth carrying with you when you read any label.
These guides tell you what a product is generally taken for and what to check before buying. They do not tell you that you need it. Most people eating a reasonably varied diet do not have a deficiency, and a supplement cannot fix a problem it was never the cause of. Where a genuine deficiency is suspected, a blood test ordered by a doctor answers the question properly, and guessing is both more expensive and less useful.

How to choose the right guide
Search the exact product name on the tub or box. Supplement brands in South Africa often sell several formulations under one family name, and the strengths differ enough that the guides are not interchangeable.
If you are looking for a nutrient rather than a brand, start from the topic list. Bear in mind that the same nutrient appears in many products at very different strengths — a multivitamin, a single-nutrient tablet and a fortified drink can all contain vitamin B6, and only one of them is likely to be near a meaningful dose.
Where a product combines several ingredients, read the guide for the ingredient you actually care about. Combination products are often chosen for one component, and the rest is filler you are paying for.
Safety, accuracy and South African context
Supplements are not automatically safe because they are sold without a prescription. Several interact with prescription medicines, and a few are genuinely risky at high doses.
Check with a pharmacist or doctor before starting a supplement if you:
- take prescription medicine of any kind, particularly blood thinners, thyroid medicine or antiretrovirals;
- are pregnant, trying to conceive, or breastfeeding;
- are buying it for a child;
- have a liver or kidney condition;
- are about to have surgery or a blood test.
Two specifics are worth knowing. Iron is the most common cause of supplement poisoning in young children, so it belongs out of reach and in its original container. Fat-soluble vitamins — A, D, E and K — accumulate in the body in a way that water-soluble vitamins do not, so “extra” is not harmless.
Tell any doctor treating you about everything you take, including herbal products. A supplement is easy to forget when someone asks what medication you are on, and it is exactly the sort of thing that changes an interaction picture.
Where these guides make a factual claim, they follow the product label, manufacturer information and credible published sources, and they separate wellness use from treatment claims rather than blurring the two.

Frequently asked questions
Do I actually need a supplement? Often not. A varied diet covers most needs for most people. Genuine deficiencies exist and matter, but they are diagnosed with a test rather than assumed.
Is a more expensive brand better? Not necessarily. Compare the amount of the active nutrient per dose rather than the price or the packaging. Two products at very different prices frequently deliver the same thing.
Can I take several supplements together? Sometimes, but overlapping products can push a single nutrient well past a sensible intake, particularly when a multivitamin is combined with single-nutrient tablets. Add up the totals, and ask a pharmacist if you are unsure.
Will a supplement treat my condition? These guides do not make treatment claims. If you have a diagnosed condition, the treatment decision belongs with your doctor.
Are these guides specific to South Africa? Yes. They reference products and pack formats sold here and point to South African professionals. Availability and formulation elsewhere may differ.
