> Use shop advice as a starting point, not a prescription. Staff are usually salespeople, not registered dietitians, and may earn commission or work to sales targets. In South Africa, ask for the evidence and the dose, compare prices per serving, and see a registered dietitian or doctor for medical conditions, medication, pregnancy or under-18 advice.

Key facts:
- SAIDS advises athletes to see a registered sports dietitian before using supplements; products from well-known brands, stores or pharmacies can still contain undeclared banned substances.
- Dietitians and doctors are regulated by the HPCSA; pharmacists by the SAPC; shop staff are not regulated for nutrition advice.
- SAIDS says no supplement brand is 'SAIDS approved' or 'WADA approved'; such claims are false.
- Beginners need at most creatine (3-5 g a day) and, if food falls short, a protein powder.

## Why is shop advice a conflict of interest?

Staff in gym shops and supplement stores sell products. Many are knowledgeable, but the incentives (commission, targets, brand promotions) push toward more products, higher-margin brands and "stacks". That does not make them dishonest. It means you should check what they say.

## What qualifications should you look for?

| Adviser | Regulated by | What they can offer |
|---|---|---|
| Registered dietitian | HPCSA | Individual nutrition plans, medical conditions, sports nutrition |
| Doctor / sports physician | HPCSA | Medical advice, deficiency testing, medication review |
| Pharmacist | SAPC | Interactions with medicines, product information |
| Shop assistant or gym trainer | Not regulated for nutrition advice | Product knowledge, usually brand-focused |

SAIDS advises athletes to see a registered sports dietitian before using supplements, and notes that products from well-known brands, stores or pharmacies can still contain undeclared banned substances.

## What are the red flags?

- **Selling a "stack"** of five products to a beginner. Beginners need, at most, creatine and perhaps protein; see [what a gym beginner should buy first](/answers/best-supplements-for-beginners-south-africa/).
- **Fat burners, "testosterone boosters" or prohormone-style products** recommended without questions about age, health and medication.
- **Pre-workouts for teenagers.** Not appropriate; see [can teenagers take pre-workout](/answers/can-teenagers-take-pre-workout-south-africa/).
- **Claims such as "clinically proven", "SAHPRA approved" or "WADA approved".** SAIDS says none of these apply to supplement brands; see [is "clinically proven" legal](/answers/is-clinically-proven-on-a-supplement-label-legal-south-africa/).
- **Pressure to buy the biggest tub** or a bundle without comparing cost per dose.
- **No answer on dose.** Ask how much of the active ingredient is in a serving.

## How do you test advice quickly?

1. **Ask what evidence supports it** and whether the study used the same dose and population.
2. **Check against reference points:** creatine 3-5 g, protein 1.4-2.0 g/kg, caffeine 3-6 mg/kg, per the ISSN. See [which supplements actually work](/answers/which-supplements-actually-work/).
3. **Convert to cost per dose.** See [how to compare supplement prices](/answers/how-to-compare-supplement-prices-per-serving/).
4. **Take a photo of the label** and check it at home, away from the sales conversation.
5. **For medical questions,** go to a doctor, dietitian or pharmacist.

## What about gyms that sell supplements?

Gyms often sell brands under wholesale arrangements; some suppliers, ATP Fitness included, sell through gyms and wholesale channels. A gym's own recommendation may reflect the supply deal. That is a reason to check, not to avoid them.

## What about minors and athletes?

For school athletes, SAIDS and BokSmart emphasise food first, and SAIDS recommends against performance supplements for under-18s. For drug-tested adults, "the shop sells it" is not a defence under strict liability. Read [what third-party tested means](/answers/what-does-third-party-tested-mean/).
