The Powerlifting Supplement Stack: What Actually Adds Kilos
Powerlifting is a maximal strength sport — three lifts, nine attempts, total weight. The supplement priorities are different from a bodybuilder's stack or an endurance athlete's. Here's what the evidence actually supports for moving more weight.
1. Creatine Monohydrate — 5 g/day
The single most validated strength supplement ever studied. Expect 5–10% improvement in 1RM strength over a training block, plus enhanced training volume that compounds over years. No reason any powerlifter shouldn't take it.
2. Caffeine — 3–6 mg/kg, 45–60 min pre-lift
Reliably improves 1RM in trained lifters across squat, bench, and deadlift studies. Test the dose in training first — some lifters perform better at 3 mg/kg than 6.
3. Protein — 1.6–2.2 g/kg/day
Powerlifters don't need 3–4 g/kg "to recover from heavy training." The MPS data caps around 1.6–2.2. Spend the extra calories on carbs to fuel volume.
4. Carbohydrates Around Training
Heavy training depletes glycogen. 1–3 g/kg of carbs 1–3 hours pre-session supports working sets across squats and deadlifts. Carbs are the real "pre-workout" for a strength athlete.
5. Beta-Alanine — 3.2 g/day (Optional)
Less impactful for the competition lift itself, but useful for accessory volume work — back-off sets, hypertrophy blocks, and high-rep squat/deadlift volume.
6. Vitamin D — 2,000–4,000 IU/day if Deficient
Vitamin D deficiency is correlated with reduced muscle strength. Most lifters in northern climates and indoor training are below optimal — test, then dose.
Meet-Day Protocol
Caffeine 45 min before your opener. Carbs and electrolytes throughout the day. Nothing new on the platform — every supplement should have been used in a heavy session first. Smelling salts are not a supplement, but they show up at every meet anyway.
What to Skip
BCAAs, glutamine, testosterone boosters, "nitric oxide" matrices. None move the needle for maximal strength. Spend that money on food and creatine.
The Bottom Line
Creatine, caffeine, protein, carbs. That's 95% of the value. Build the four, get strong, then worry about extras.
Frequently Asked Questions
- Does creatine help maximal strength or just hypertrophy?
- Both. Meta-analyses show 5–10% improvements in 1RM strength on top of training, on top of hypertrophy effects. It's the most validated strength supplement in existence.
- Pre-workout for a meet?
- Caffeine 3–6 mg/kg, 45–60 minutes before your opener. Skip novel ingredients on meet day — test everything in training first.
- Beta-alanine for a single lift?
- Limited benefit. Beta-alanine helps 1–4 minute efforts. For a 5-second deadlift, it's secondary — useful for accessory volume, not for the competition lift.
- Should I cut weight or eat into the next class?
- Most lifters lift better well-fed. Aggressive cuts compromise strength. Stay in your weight class with a 24–36 hour mild manipulation, not a brutal water cut.
