> Whey protein is not banned or inherently harmful for teenagers, but food should come first, and under-18s should see a registered dietitian before using powder. South African school sport has a doping problem driven by steroids and contaminated products, not by plain whey, so avoid multi-ingredient 'mass' or 'anabolic' powders and never use supplements to replace meals.

Key facts:
- SAIDS reported Craven Week steroid positives every year: 3 (2014), 5 (2015), 4 (2016), 3 (2017) and 6 from 122 tests (2018).
- SAIDS and BokSmart advise a food-first approach for school athletes; plain whey is not a Prohibited List substance.
- Athletes are strictly liable for any banned substance found, including through a contaminated supplement.
- USN BlueLab 100% Whey costs R689 per kg (about R28 per 30 g protein), October 2026.

## Can teenagers take whey protein in South Africa?

Safe use is possible, but the right order is food first, powder as a convenience, and professional advice for anyone under 18. Evidence on adolescent protein powder use is limited, so we stay conservative.

## Do teenage athletes need extra protein?

Active teenagers need enough energy and protein to grow and train. The ISSN guidance of 1.4 to 2.0 g per kg per day was drawn mainly from adult data, so a dietitian should individualise targets for a teenager. Most South African teenagers can reach their needs through food.

| Food | Approximate protein |
|---|---|
| 2 large eggs | 12 g |
| 250 ml milk or maas | 8 g |
| 100 g cooked chicken breast | 30 g |
| 100 g biltong | 50 g |
| Tin of pilchards | 20 g or more |
| One scoop whey (typical) | 20 to 27 g |

These are rough guides; labels vary.

## What is the real risk in school sport?

SAIDS reported anabolic-steroid positives at Craven Week almost every year: 3 in 2014, 5 in 2015, 4 in 2016, 3 in 2017 and 6 from 122 tests in 2018. SAIDS and BokSmart (SA Rugby) emphasise a food-first approach, and SAIDS flags muscle-building, weight-loss and 'testosterone booster' products as the highest-risk categories. Under the World Anti-Doping Code, athletes are strictly liable for what is found in their sample, however it got there, including a supplement a coach or parent recommended. Plain whey is milk protein and is not on the Prohibited List, but contaminated multi-ingredient products are the danger.

## If a dietitian approves whey, how do you choose?

1. Pick a single-ingredient or simple whey, not a "mass", "anabolic" or stimulant blend.
2. Prefer a batch-tested product if the teenager competes under anti-doping rules, and verify the batch on the certifier's own register ([what Informed Sport means](/answers/what-is-informed-sport-certification-south-africa/)). USN and Biogen state certification on their pages; ATP Fitness does not publish any.
3. Keep portions to one scoop after training, not a replacement meal.
4. Do not combine with creatine, pre-workout or fat-burners without medical advice ([supplements under 18](/answers/supplements-under-18-what-parents-should-know-south-africa/)).

## What does it cost?

USN BlueLab 100% Whey is R689 per kg (about R28 per 30 g protein, October 2026). A glass of milk or two eggs is usually cheaper per gram of protein and adds other nutrients.

## When should you see a professional?

Before starting, speak to a registered dietitian or sports physician. See a doctor straight away if your teenager has a milk allergy, kidney disease, digestive symptoms, rapid unintended weight change, or is using any supplement to cut weight. Parents should also be alert to steroid use: see [supplements for schoolboy sport](/answers/supplements-for-schoolboy-sport-south-africa/).
