WHAT IS HAPPENING
After about sixty, two things work against your muscle at once. Appetite and the per-meal response both decline, so the same breakfast that fed you at forty does less at seventy, and you tend to eat less of it.
The muscle’s reduced response to a given dose of protein and to a given bout of exercise is called anabolic resistance. Basal turnover does not fall much with age; a healthy seventy-year-old at rest is building and breaking down muscle at close to the rate a thirty-year-old is. What falls is the response to the signal. Give the same 20 grams of protein to both and the older muscle responds less, which is why the per-meal dose has to go up, not just the daily total [1, 2]. In the tracer dose-response work, young muscle reached its maximum synthesis response at about 0.24 grams of protein per kilogram of body weight in a meal; older muscle at about 0.40 [1]. I have written that story in full at the protein-per-meal threshold.
The clinical name for the muscle loss itself, once it crosses a threshold of low mass and low strength, is sarcopenia, and it is a diagnosis your doctor can make, using grip strength and the chair-stand test among other measures [3]. I am going to say this once, clearly, so there is no confusion later: a supplement does not treat, prevent or reverse it, and I will not say it does.
WHAT THE EVIDENCE SUPPORTS, AT ITS REAL SIZE
The geriatric nutrition societies, after reviewing the field, recommend 1.0 to 1.2 grams of protein per kilogram per day for healthy older adults and 1.2 to 1.5 when ill or recovering, paired with exercise [4, 5]. That is well above the 0.8 on the government chart, which was set to prevent deficiency, not to keep legs strong. Our evidence chart carries it as the protein guideline entry for adults 65+, graded good.
Observational data point the same way. In a large cohort of adults aged 70 to 79, those in the highest protein group lost about 40 percent less lean mass over three years than those in the lowest [6]. A later analysis in the same cohort, using a different muscle measure, found no association, so I hold that one loosely [7]. One cohort, two answers; that is what “promising” looks like, and I would rather show you both than pick the one I like.
On supplements, be clear-eyed. Leucine reliably raises the muscle-building signal in older adults but does not reliably add lean mass over months: a meta-analysis of nine trials found the synthesis effect without the body-composition effect [8], and a review of leucine-rich protein supplements in the elderly found the same pattern [9]. That is the leucine entry on the chart, mixed results. The largest sarcopenia nutrition trial, nearly 400 older adults on a leucine-enriched whey and vitamin D supplement, improved muscle mass and a chair-stand measure but missed its primary strength endpoints [10]; the chart carries it as mixed.
The essential-amino-acid trials that show lean-mass gains in older adults are real and they are small: a dozen or so people each, mostly from one research group, including the bed-rest study in which older adults given essential amino acids held onto leg muscle and strength that the others lost [11, 12, 13]. The chart grades the essential amino acids and lean mass in older adults entry as promising, which is the right word for consistent small trials. HMB, a leucine metabolite, does little in athletes but helps preserve muscle in the frail and the bed-bound [14, 15]; see the HMB in older adults entry, which carries a caveat that the grade is borderline.
Read those four paragraphs together and the pattern is clear. The nutrition evidence in older adults is consistent on the signal and modest on the muscle. Which brings me to the thing that is not modest.
THE ONE INTERVENTION THAT BEATS ALL OF THEM
Resistance training. A meta-analysis of 49 studies found that resistance training added about 1.1 kilograms of lean mass in older adults, supplement or no supplement [16]. And the famous trial in frail nursing-home residents aged 72 to 98 showed strength and mobility gains from lifting that nutrition supplements alone did not produce [17]. Ninety-year-olds got stronger! If there is an age at which the muscle stops answering the load signal, nobody has found it yet.
Creatine, taken with resistance training, is the best-evidenced add-on in the whole category: about 1.4 kilograms more lean tissue than training alone across 22 trials in older adults [18]. That is the chart’s creatine with resistance training in older adults entry, graded strong. It is worth a conversation with your doctor, and it is not an amino acid supplement in the everyday sense.
If you take one thing from this page, it is that the fork and the barbell beat the capsule, and a capsule works best as a way to get the fork’s job done when appetite is the limit. That is the most optimistic sentence in my book, because forks and barbells are cheap and they are everywhere.
THE PLAN
One framework, four versions. This is version C: assess, set the target, build the meals, add the load, re-assess at four weeks, adjust.
- Target: 1.2 grams of protein per kilogram per day as a floor, not 0.8, and 1.2 to 1.5 if you are ill, recovering, or already losing [4, 5]. Spread it so that three meals clear the older-adult per-meal bar of roughly 30 to 40 grams [1, 19].
- Breakfast is the lever. Older adults most often miss the bar at breakfast, where toast and coffee carry almost no protein. Eggs, Greek yoghurt, dairy, or a shake at breakfast is the single highest-payoff change for most people in this group.
- Load. Resistance training two or three times a week, started wherever you are, even seated bands, even standing from a chair on purpose. This is not optional; it is the part that works [16, 17].
- A protein source (whey, a complete essential-amino-acid blend, or a leucine-enriched product, chosen as a category) earns its place when appetite, chewing or shopping keeps you below the bar at a meal. Creatine with training is worth a conversation with your doctor [18].
- Re-assess at four weeks: grip, the five-chair-stand, and whether breakfast is clearing the bar. Direction over single numbers.
Key Points:
- The per-meal dose rises with age because older muscle responds less to the same signal; 30 to 40 grams per meal is the working bar after sixty [1, 2, 19].
- Geriatric societies recommend 1.0 to 1.2 g/kg/day for the healthy and 1.2 to 1.5 when ill, with exercise [4, 5].
- Leucine, leucine-enriched whey and essential amino acids raise the signal reliably and add lean mass inconsistently, in small or mixed trials [8, 9, 10, 11, 12, 13].
- Resistance training added about 1.1 kg of lean mass across 49 studies and worked in nonagenarians; creatine with training added about 1.4 kg more across 22 trials [16, 17, 18].
- Sarcopenia is a medical diagnosis. No supplement treats, prevents or reverses it [3].
REAL-WORLD OBSTACLES
The plan above assumes you can shop, chew and cook. Many cannot, every day, and the plan has to bend without breaking.
- Dentures or dental pain: soft proteins carry the same amino acids as a steak. Eggs, fish, dairy, tofu, minced and slow-cooked meat, a shake.
- Cooking for one, or grief, or low mood: the breakfast fix matters most because it needs the least effort. A tub of Greek yoghurt, a carton of liquid eggs, a scoop in milk. Make the easy meal the protein meal.
- Shopping limits: shelf-stable protein (canned fish, dairy that keeps, a protein powder) removes the “I ran out” failure.
- A small appetite: a dose that misses the per-meal bar still counts toward the daily total. Six small feedings can build a day that three meals cannot. Plate protein first and eat it first.
HOW TO MEASURE WHETHER IT IS WORKING
The scale tells you about weight. These two tell you about muscle that works, which is the thing you actually care about, and they are the measurements the sarcopenia researchers settled on because they predict falls, disability and recovery better than a bathroom scale does [3].
- Grip. A hand dynamometer costs about the price of two bottles of any supplement. Squeeze it hard three times with each hand and record the best. The European working group’s cut-points for concern are below 27 kilograms for men and below 16 kilograms for women [3].
- Chair stand. Sit in a dining chair, arms folded across your chest, and stand up and sit down five times as fast as you safely can while someone times you. Longer than about 15 seconds is the working group’s cut-point for poor lower-body strength [3].
- Weight trend. Losing faster than about one percent of your body weight per week, for any reason, pulls disproportionately from lean tissue [20]. Unintended loss is a doctor’s visit, not a bigger scoop.
- Re-test every four weeks. Grip climbing and chair stands getting faster is the plan working, whatever the scale says.
RED LINES
Sarcopenia is a medical diagnosis; a supplement does not treat, prevent or reverse it. If you are losing weight you did not intend to lose, that is a doctor’s visit. And get your kidney numbers checked (creatinine and eGFR) before a sustained high-protein push at this age. For healthy adults, a meta-analysis of 28 trials found no change in kidney filtration on higher-protein diets [21], but the ordinary “healthy kidneys handle it” rule needs to be confirmed to apply to you, and for diagnosed chronic kidney disease the guidelines set a lower, controlled intake, written by your clinician [22].
The Bottom Line. After sixty the breakfast has to carry more protein, the daily target is 1.2 grams per kilogram as a floor, and the thing with the strongest evidence is a barbell, a band, or a chair you stand up from on purpose. The supplements raise a signal; the training builds the muscle. Measure your grip and your chair stands, re-test in four weeks, and finish every month better than you started it. Then get educated, ask questions, and advocate for yourself.
