> 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.

Key facts:
- 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](/answers/how-much-protein-per-day-south-africa/).

## 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](/best/best-creatine-south-africa/) and [can creatine cause a failed drug test](/answers/can-creatine-cause-a-failed-drug-test-south-africa/).

## What about schoolboys and seniors?

Under-18s should follow a food-first approach ([supplements for schoolboy sport](/answers/supplements-for-schoolboy-sport-south-africa/)). 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.
