Best supplements for age-related muscle loss (sarcopenia)

Resistance training is the main treatment for age-related muscle loss: international sarcopenia guidelines strongly recommend it, while protein gets only a conditional recommendation. Supplements add modest gains on top of training, mostly in people who are already losing muscle or eating too little protein. Picks are ranked by the evidence in older adults, not by popularity.

Picks are ranked by the strength of published evidence for this goal in otherwise healthy adults. A persistent symptom needs a clinician's evaluation, and no supplement on this list replaces treatment.

Solid options

OptionEvidenceBest forThe honest note
Whey Protein Isolate Strong evidence older adults losing muscle Meta-analyses show whey with resistance exercise improves muscle mass and strength in sarcopenia, and one found gains in lean mass and function in sarcopenic or frail adults but not in healthy ones. Use 20–40 g per serving toward your daily target; older adults often need the higher end. View
Creatine (monohydrate) Strong evidence more strength from resistance training In a meta-analysis of 8 trials with 482 older adults, creatine plus resistance training raised leg strength and lean mass more than training alone, though the effects were small. Take 3–5 g a day, with no need to load or cycle. View
HMB (β-Hydroxy-β-Methylbutyrate) Limited evidence preserving muscle in older adults A meta-analysis in older adults found HMB added to exercise gave small gains in muscle mass and some strength measures, and it is most useful in older, untrained or clinically compromised people. The study dose is 3 g a day, split across meals. View
Urolithin A Moderate evidence muscle endurance, not mass Two 4-month trials in middle-aged and older adults found better muscle endurance or strength at 500–1,000 mg a day, but the primary endpoints, such as 6-minute walk distance, did not consistently improve. Most trials were funded by the manufacturer. View

Situational

OptionEvidenceBest forThe honest note
Free-Form Amino Acid Complex Moderate evidence undernourished or low-appetite older adults With resistance training, amino acids improved grip strength, gait speed and physical performance in sarcopenia, at low certainty and with little effect on muscle mass. The benefit concentrates in undernourished people; if you already eat enough protein, food does the same job. View
EAA (Essential Amino Acids) Moderate evidence when appetite limits protein intake Improvements in older adults are small, clearest where protein intake was inadequate, and shrink toward zero once protein targets are met. Trials gave 7.5–15 g twice daily between meals. View
Vitamin D3 Strong evidence only when blood levels are low In a meta-analysis of 10 trials, vitamin D alone did not improve any sarcopenia measure in community-dwelling older adults, and the guidelines make no recommendation for it. Correct a measured deficiency for bone health, where the evidence is strong. View

Training for this goal

Supplements only help on top of the right training. The evidence-graded base program for this goal:

Strength training after 50: what the evidence says

Free base program: 2–3 days full body after 50

Frequency
2–3 full-body sessions per week, never two days in a row
Weeks 1–4
1–2 sets of 10–15 reps with light loads, stopping 3–4 reps short of failure, to learn the movements
From week 5
2–3 sets of 8–12 reps, building toward about 70–80% of 1RM, 1–3 reps in reserve
Rest
1.5–2 min between sets

See the full program →

How to get stronger: what the evidence says

Free base program: 3-day full-body strength

Frequency
3 full-body sessions per week, each main lift 2–3× per week
Main lifts
3–5 sets of 3–6 reps at about 80–90% of 1RM, 1–3 reps in reserve
Assistance
2–3 sets of 6–12 reps for rows, pulldowns, lunges, core
Rest
3–5 min on main lifts, 1–2 min on assistance

Popular for this goal — but the evidence says skip

  • Nicotinamide Riboside Limited evidence

    A 2025 meta-analysis of NAD+ precursor trials found no effect on muscle mass or function, despite clear rises in NAD+.

  • NMN (Nicotinamide Mononucleotide) Limited evidence

    Pooled NMN and NR trials show no effect on muscle mass or strength, and NMN can no longer be legally sold as a dietary supplement in the US.

  • DHEA Moderate evidence

    In 25 trials in older men the only measured benefit was a modest drop in fat mass that disappeared after adjusting for hormone changes, and it is banned in sport.

  • Turkesterone Limited evidence

    No human randomized trial exists, and independent testing finds many products contain little or no turkesterone.

  • BCAA (Branched-Chain Amino Acids) Limited evidence

    Without the other six essential amino acids, BCAAs cannot build muscle, and complete protein beats them in head-to-head comparisons.

Our verdict

Do resistance training 2–3 times a week and get enough protein, using whey if food falls short, then add 3–5 g of creatine a day if you want more from the training. Skip NAD+ boosters, DHEA, turkesterone and BCAAs. If you have kidney disease, talk to your doctor before taking protein powders or creatine, and get unexplained weight or strength loss checked.
