You've done the work for decades. The parkruns, the long rides, the early mornings. But somewhere after 45, something shifted: the same session that used to take a day to bounce back from now takes two or three. You're not slower because you've lost your edge — you're slower to recover. And there's a well-documented physiological reason for it.
It's called anabolic resistance
As we age, our muscles become less responsive to the protein we eat. The same meal that triggered strong muscle repair at 30 produces a blunted response at 55. Researchers call this anabolic resistance — and it means older athletes need more of the right amino acids, timed well, to get the same recovery signal.
Adults over 60 may need roughly double the leucine per serving to maximally stimulate muscle protein synthesis compared with younger adults.1,2
Leucine is the key. It's the amino acid that flips the "build and repair" switch in muscle. Hit the leucine threshold and recovery kicks in; fall short and the signal stays muted — no matter how hard you trained.
Why food alone often isn't enough mid-session
A steak does the job at dinner. But around training — before a long ride, mid-run, or straight after a session when your stomach can't face a meal — most athletes simply don't get a fast, complete dose of essential amino acids. That's the exact window where the over-45 body needs the most help.
- All 9 essential amino acids — the complete set your body can't make itself
- 2g leucine per serving to support the recovery signal
- Just 20 calories, zero sugar — easy on the stomach, pre, intra or post
- Lightly flavoured — not the sickly-sweet sweetener bomb most aminos are
