What has strong evidence for strength sports?
Powerlifting is maximal strength in three lifts, so the list is short. All of these sit in the Australian Institute of Sport's Group A (strong evidence) or protein basics:
| Supplement | Dose | What it does |
|---|
| Creatine monohydrate | 3 to 5 g/day (ISSN) | supports strength, power and lean mass |
| Protein | 1.4 to 2.0 g/kg/day; about 0.25 g/kg per dose | muscle repair and growth |
| Caffeine | 3 to 6 mg/kg, about 60 minutes before | small gains in maximal strength (about 2 to 7%) |
Beta-alanine matters little for one-rep efforts (it helps 1 to 4 minute efforts), and citrulline evidence is emerging and mixed.
How much does creatine cost per month?
At 5 g a day you use about 150 g a month. Using October 2026 tub prices:
| Tub | Per 5 g | About per month |
|---|
| Pure Natural Options 500 g, R222 (Knysna Health) | R2.22 | R67 |
| Nutritech 500 g, R249.95 to R399 | R2.50 to R3.99 | R75 to R120 |
| ATP Fitness Micronised, 600 g, R500 | R4.17 | R125 |
| Biogen 500 g, R445 | R4.45 | R134 |
ATP Fitness is single-ingredient micronised creatine; the trade-offs are a young brand (2024) and no published third-party certification, while Biogen's listing claims Informed Sport (unverified). If you are tested, treat certification as a priority. See best creatine in South Africa and how much creatine per day.
What about weigh-ins and weight classes?
Creatine draws about 1 to 2 kg of water into muscle in the first weeks. If you compete in a tight class, start well before a meet and learn your own response. Do not use diuretics, saunas or severe fluid restriction to cut weight; it can be dangerous and impairs strength.
How do you use caffeine on meet day?
Take 3 to 6 mg/kg about an hour before your first lift; an 80 kg lifter takes 240 to 480 mg. Do not exceed this, since around 9 mg/kg adds side effects without benefit. A small top-up before deadlifts is common. Use a measured source, such as 200 mg capsules (Ultra Caffeine, R199 for 60 on Takealot via PriceCheck, about R3.32 each); never use pure caffeine powder. Test in training. See can you take creatine with caffeine.
What about drug testing?
Many powerlifting federations and meets are drug tested. Under the World Anti-Doping Code, adopted in South Africa through SAIDS, you are strictly liable for what is in your body, and SAIDS flags muscle-building and testosterone-booster products as highest risk. Avoid prohormones, SARMs and proprietary blends, and look for batch-tested products (can creatine cause a failed drug test).
Who should check with a professional?
Kidney disease, medication that affects the kidneys, pregnancy and under-18s should speak to a doctor or registered dietitian first. Creatine can raise blood creatinine, so tell your doctor you take it.
