HMB and Other Recovery Supplements: What's Actually Worth It

Recovery supplements are a $4B industry. The research on which ones actually work is narrower than the marketing suggests — here's the honest sorting after a decade of testing and reading the actual literature.

I've worked through most of the major recovery supplements over the last ten years — sometimes in my own training, sometimes through research deep-dives. Spending $200 a month on stacks that don't work is a real cost. Here's what the evidence actually supports.

Three with real evidence behind them

1. Protein. Whey, casein, or whole-food. The single best-supported recovery intervention. 30–40g within two hours of training has consistent evidence for muscle protein synthesis. Whey absorbs fastest; casein is slower-release and better before bed. Whole-food sources work fine for most people most of the time.

2. Creatine monohydrate. 5g daily. The most-studied performance and recovery supplement that exists. Real effects on strength, power, and recovery time. Cheap, unflavored, boring. Works.

3. Tart cherry. Some real evidence for reduced muscle soreness, particularly in endurance athletes. Effect sizes are modest but consistent across studies. Cost is moderate; benefit is real enough to try if soreness is the issue.

The HMB question specifically

HMB has mixed evidence. It shows useful effects for previously untrained subjects and during caloric deficit phases. Less convincing for experienced lifters eating adequate protein. The marketing overstates the typical case significantly. If you're a beginner or returning from a long layoff, 3g daily might marginally help. If you're a trained lifter eating enough protein, the marginal benefit is small.

What's overrated

BCAAs — if you're hitting your protein targets, BCAAs add nothing; the category is mostly marketing. Glutamine — same story; adequate protein covers it. "Recovery formula" multi-ingredient stacks are usually protein plus creatine plus something else, priced three times what the individual ingredients cost separately.

What actually drives recovery

Sleep above 7 hours — tracked with a Garmin watch or Apple Watch — is the single biggest variable, and it's free. Real food protein at every meal, 0.8–1g per pound of body weight distributed across the day. Hydration throughout the day. Ten minutes daily on a foam roller — boring, but it works. A massage gun on heavy training days has consistent subjective benefit for most users even if the long-term research is mixed.

What to skip

Pre-workout stimulant blends — some real short-term effects, but plain coffee is a better default with less adrenal-fatigue risk. Multi-ingredient "recovery stacks" at premium prices. Anything with proprietary blends that don't list individual ingredient doses — that's how the industry hides under-dosing.

Protein, creatine, and optionally tart cherry cover 90% of legitimate recovery supplementation. Total monthly cost: $40–$60. Adding more rarely produces measurable returns on top of that. The actual recovery work is sleep, food, hydration, and movement. The supplement industry sells complexity because complexity is profitable — the boring stack is what actually works.
