Where it strikes

Medical treatment

  • Resistance training prescription
  • protein optimisation
  • treat vitamin D deficiency
  • manage chronic disease
  • nutrition referral

Natural & lifestyle

  • Progressive resistance training 2–3×/week (nothing else comes close)
  • protein 1.2–1.6 g/kg spread across meals
  • leucine-rich foods
  • vitamin D
  • creatine 3–5 g

Emerging & experimental

  • Myostatin inhibitors
  • apelin analogues
  • combination with GLP-1 to preserve lean mass

Alternative, off-label & anecdotal

Approaches used outside the guidelines, with what their supporters report and what testing has found so far.

  • HMB (beta-hydroxy-beta-methylbutyrate) — trials show better muscle preservation in some mixed evidence
  • Urolithin A — early trials improved muscle endurance early / small studies
  • Omega-3 — small trials added strength to training early / small studies
