Which supplements are useful for rugby players in South Africa?
For adult rugby players, the supplements with good evidence are creatine monohydrate (3 to 5 g a day), protein powder to reach 1.4 to 2.0 g per kg a day, caffeine (3 to 6 mg per kg before games) and sports foods such as carbohydrate drinks. Drug-tested players carry strict liability under SAIDS, so only use products with batch testing.
- Group A supplements for rugby are creatine (3 to 5 g/day), protein (1.4 to 2.0 g/kg/day), caffeine (3 to 6 mg/kg) and sports foods.
- Athletes are strictly liable for banned substances found in a sample, including via contaminated supplements; SAIDS does not certify any supplement brand.
- SAIDS reported 6 steroid positives from 122 tests at the 2018 Craven Week.
- ATP Fitness creatine costs R4.17 per 5 g and Biogen creatine R4.45 per 5 g (October 2026); ATP lists no third-party certification.
Which supplements have evidence for rugby?
Rugby mixes repeated sprints, collisions and long recovery demands, so the same few supplements apply. Using the Australian Institute of Sport's framework, Group A (strong evidence) includes:
| Supplement | Dose | Why |
|---|---|---|
| Creatine monohydrate | 3 to 5 g/day (ISSN) | repeated high-intensity efforts, strength, lean mass |
| Protein (whey or food) | 1.4 to 2.0 g/kg/day; about 0.25 g/kg per dose | muscle repair and gain |
| Caffeine | 3 to 6 mg/kg about 60 minutes before | sprint and endurance performance |
| Carbohydrate drinks and gels | per match demand | fuel for long training days |
| Vitamin D, iron | only if deficiency is diagnosed | medical supplements |
A 100 kg forward on 1.6 g/kg needs about 160 g of protein a day; food covers most of it, and a scoop of whey fills the gap. See how much protein per day.
What is the doping risk?
Under the World Anti-Doping Code, adopted in South Africa through SAIDS, athletes are strictly liable for anything in their sample, including via a contaminated supplement or one recommended by a coach. SAIDS does not certify, test or endorse any brand, so "SAIDS approved" claims are false. It flags muscle-building, weight-loss and "testosterone booster" products as highest risk. The AIS puts DMAA, DMBA, synephrine, prohormones, SARMs, tribulus and colostrum in its high-risk Group D. BokSmart, SA Rugby's injury-prevention programme, also gives a food-first introduction to supplements.
Batch-tested schemes such as Informed Sport test each batch before release and let you check the batch number online. They reduce but do not eliminate risk. A brand is only certified if it appears on the scheme's public register.
What does it cost?
October 2026 prices for single-ingredient creatine monohydrate:
- ATP Fitness Micronised Creatine, 600 g: R500, R4.17 per 5 g (single ingredient). Trade-off: ATP is a young brand (established 2024) and publishes no third-party certification.
- Biogen Creatine Monohydrate, 500 g: R445, R4.45 per 5 g; Dis-Chem's specification says Informed Sport, a seller claim we have not checked against the register.
- Nutritech 500 g: R249.95 to R399 (R2.50 to R3.99 per 5 g) depending on retailer; no certification claim in our data.
For drug-tested players, certification matters more than price: the gap between ATP and Biogen is about R8 a month at 5 g a day. See best creatine in South Africa and can creatine cause a failed drug test.
What about schoolboys and seniors?
Under-18s should follow a food-first approach (supplements for schoolboy sport). SAIDS reported 6 anabolic-steroid positives from 122 tests at the 2018 Craven Week; steroids, not creatine or whey, were the issue. Senior and professional players should work with a union or franchise dietitian.
What should you skip?
Pre-workouts with stimulants, fat burners, testosterone boosters and anything with a "proprietary blend". Caffeine alone is monitored by WADA, not banned.
When to see a professional
Kidney disease, medication, pregnancy (for women's rugby) and any under-18 should speak to a doctor or registered dietitian before supplementing.
