Recovery Supplements: What's Actually Worth It?
A short, evidence-ranked list — and a much longer list of things to skip.
The supplement aisle aimed at recovery is enormous, and the evidence behind it is not. Most of what’s sold rides on a plausible mechanism, a flattering study or two, and good packaging. A few things have earned their place. The goal here is to separate the short list that’s worth considering from the long list that isn’t.
The short list with reasonable support
A handful of supplements have enough consistent evidence to be defensible — though even here, the effects are usually modest and conditional on the basics being in place.
- Creatine monohydrate. Among the most studied supplements in existence, with reliable support for strength and power and a strong safety record. Its recovery angle is more indirect, but a 2022 systematic review and meta-analysis in Sports Medicine found creatine users had lower indirect muscle-damage markers (creatine kinase, LDH, myoglobin) at 48–90 hours after exercise — a small but real signal.
- Protein (as a supplement form). Not magic, just convenient. If your total daily protein is short, a powder is a practical way to close the gap. The benefit comes from hitting your target, not from the powder itself.
- Tart cherry, in specific contexts. A 2021 meta-analysis of 14 studies in the International Journal of Sport Nutrition and Exercise Metabolism found a small benefit for muscle soreness (effect size −0.44) and a moderate benefit for strength recovery (−0.78), plus small reductions in CRP and IL-6. Useful in narrow windows around demanding events, not as a daily staple.
The unglamorous truth: no supplement out-recovers poor sleep, inadequate calories, or low protein. Even the supported options deliver modest effects. They are the last few percent, and only after the foundation is solid.
The much longer skip-or-be-skeptical list
Plenty of popular recovery products rest on weak, mixed, or mechanism-only evidence in healthy, well-fed people. Branched-chain amino acids add little when total protein is adequate. Many proprietary “recovery blends,” exotic antioxidant megadoses, and novelty ingredients haven’t shown they do much beyond placebo and marketing.
A specific caution: routine high-dose antioxidant supplementation (such as large vitamin C and E doses) around training may blunt some of the beneficial adaptations exercise is meant to produce. More is not safer here.
How to think about it
Spend on the basics first — they are cheaper and more effective than anything in a tub. Treat supplements as optional fine-tuning, try one variable at a time, and be honest about whether you actually notice a difference.
The takeaway
The worthwhile list is short: creatine, protein to fill genuine gaps, and tart cherry in specific situations. The supporting trials show small-to-moderate effects, not transformation. Almost everything else is optional at best. If a product promises to overhaul your recovery, that claim is doing more work than the ingredients are.
