There’s a lot of noise around post-workout supplements — half of it’s marketing, half of it’s outdated “bro science” that’s stuck around since the 90s. Here’s what’s actually worth your money and what isn’t, broken down simply.
The Quick Version
| Supplement | What It Does | Typical Dose | Worth It? |
|---|---|---|---|
| Protein | Repairs and builds muscle | 20–40g | Yes — foundational |
| Carbs | Refills energy stores | 30–60g | Yes, especially after hard/long sessions |
| Creatine | Strength, power, recovery | 3–5g daily | Yes — one of the best-studied supplements out there |
| Electrolytes | Hydration, cramp prevention | Varies | Situational — depends how much you sweat |
Protein: Still the Foundation
This one isn’t controversial. Protein gives your body the amino acids it needs to actually repair and build the muscle you just broke down training. Somewhere in the 20–40g range post-workout is a solid target, with older adults leaning toward the higher end since muscle becomes more resistant to protein synthesis with age.
Rough guide by bodyweight: 0.3–0.4g/kg post-workout. For a 180 lb person, that’s roughly 25–33g.
Here’s something worth knowing that a lot of older content gets wrong: the idea of a strict “2-hour anabolic window” where you must eat protein or lose your gains has been walked back significantly by more recent sports nutrition research. Total daily protein intake matters far more than nailing the timing to the minute. If you eat well-spaced protein throughout the day, a workout followed by a meal an hour or two later is completely fine.
Carbs: Refueling the Tank
Carbohydrates replenish glycogen — your muscles’ stored fuel — and they spare protein from being burned for energy instead of used for repair. This matters more after long or high-intensity sessions than after a casual 30-minute lift.
Dosage: Roughly 0.5–1.0g/kg post-workout, paired with your protein. For most people, that’s somewhere around 30–60g — think a banana, some rice, or oats.
Real research on timing here (from classic glycogen studies out of the University of Texas) does show that eating carbs immediately after training refuels glycogen meaningfully faster than waiting a couple hours — so if you’re training twice in a day or need fast turnaround, timing does matter more here than it does for protein.
Creatine: The Best-Studied Supplement Out There
Creatine increases available energy for short, intense efforts and draws water into muscle cells to support growth. It’s genuinely one of the most well-researched supplements that exists — the International Society of Sports Nutrition’s position stand backs it as safe and effective across a wide range of ages.
Dosage: 3–5g daily, any time of day. A loading phase (20g/day for 5–7 days) speeds up saturation but isn’t necessary — you’ll get to the same place in a few weeks either way.
Electrolytes: Situational, Not Universal
If you’re sweating heavily — long runs, hot weather, intense sessions — electrolytes help prevent cramping and support hydration. If you’re doing a 30-minute lift in an air-conditioned gym, plain water is probably fine.
Rough target: 300–500mg sodium, 200–400mg potassium if you’re replacing what you lost in a heavy sweat session.
Putting It Together
| Goal | Priority Stack |
|---|---|
| Build muscle | Protein + Creatine |
| Fast energy recovery (2-a-days, endurance) | Carbs + Protein |
| Heavy sweater / hot climate training | Electrolytes + Protein |
| Just starting out | Protein + Carbs — keep it simple |
A simple starter combo: 25g protein + a piece of fruit or some rice + 3g creatine, sometime within a couple hours of training. Doesn’t need to be more complicated than that.
A Few Things Worth Knowing
- Timing matters less than people think — except for carbs. Protein timing is flexible; carb timing matters more if you’re training again soon.
- Creatine doesn’t need to be taken post-workout specifically. Consistency day-to-day matters more than the clock.
- Quality over hype. Look for third-party tested products (NSF Certified for Sport is a good marker) rather than whatever has the flashiest packaging.
Bottom Line
You don’t need five supplements and a fancy stack to recover well. Protein and creatine do the heavy lifting for most people. Add carbs if your sessions are long or frequent, and electrolytes if you’re sweating buckets. Everything else is optional.
