Protein Needs After 60

After 60, protein advice depends less on age alone and more on what’s happening around it, such as appetite, illness, a diet or kidney function. Humanic Blue is looking at protein needs after 60 through those different situations, because age alone does not settle the number.

Research has not established a protein threshold at 60. The long-standing US Recommended Dietary Allowance (RDA) is 0.8 grams per kilogram of body weight per day, while the 2025–2030 Dietary Guidelines use a higher general target of 1.2 to 1.6 g/kg/day. A separate 2013 geriatric expert consensus recommends 1.0 to 1.2 g/kg/day for generally healthy adults over 65 and 1.2 to 1.5 g/kg/day during many acute or chronic illnesses. These standards are not interchangeable, and chronic kidney disease can call for a lower target. A 2025 overview of 33 meta-analyses found no overall muscle, strength or performance benefit from protein supplements in healthy older groups, while reporting small benefits in groups with long-term conditions. Most of the included reviews were rated critically low quality. For living longer and better, adequate protein matters; evidence for routinely adding supplements is much narrower.

What are the protein numbers after 60?

The PROT-AGE Study Group, convened by the European Union Geriatric Medicine Society, set its recommendations for people over 65. Most of the evidence applies from about that age, not from a birthday at 60.

Situation	Daily protein (g/kg)	130 lb (59 kg)	160 lb (73 kg)	190 lb (86 kg)
RDA, all adults	0.8	47 g	58 g	69 g
2025–2030 US guideline target	1.2–1.6	71–94 g	87–116 g	103–138 g
PROT-AGE minimum, over 65	1.0–1.2	59–71 g	73–87 g	86–103 g
PROT-AGE, over 65 and active or exercising	≥1.2	≥71 g	≥87 g	≥103 g
PROT-AGE, over 65 with acute or chronic illness	1.2–1.5	71–88 g	87–109 g	103–129 g
PROT-AGE exception: severe kidney disease, not on dialysis	May need to limit	Individual	Individual	Individual

The RDA, the current Dietary Guidelines target and the PROT-AGE consensus were created by different groups for different purposes. PROT-AGE applies to people over 65, not everyone over 60, and it is not an official US guideline. How those numbers compare is covered in Protein Needs After 40. The uncertain per-meal evidence is in Protein Needs After 50.

The group explained its reasoning: older adults need more protein to stay healthy, recover from illness and keep functioning, and to counter the inflammation and muscle breakdown that come with the chronic and acute diseases common in later life.

What did supplement trials find in healthy older groups?

For this group, the trial evidence has important quality limits. An overview published in Age and Ageing brought together 33 reviews that had combined earlier study results, searched through August 2024. Across healthy older groups, supplemental protein did not improve muscle mass, strength or physical performance overall. The authors found more consistent benefits when protein was paired with exercise.

The quality caveat is large: nearly all reviews were rated low or critically low quality, and supplement amounts and study lengths varied widely. The overview did not analyze participants’ habitual diets. Its healthy groups therefore cannot be assumed to have had adequate protein intake. The finding is no clear overall supplement benefit in groups classified as healthy, with uncertainty about how starting intake affects that result.

What can a supplement review tell us when it has not analyzed participants' usual diets?

What if you’re eating less than you used to?

A 2026 analysis of a US national health survey compared protein intake and mobility in adults aged 60 and older. It found no clear statistical difference in mobility limitation between those eating at least 1.2 g/kg/day and those below 0.8 g/kg/day. Additional analyses suggested a possible link at lower intakes, but the survey measured diet and mobility at the same time. It cannot show that increasing protein improves mobility, and other differences between people could explain the association.

A trial tested whether people with low habitual intake benefit from dietary help. In the six-month PROMISS trial, researchers in the Netherlands and Finland assigned community-dwelling adults aged 65 or older who ate less than 1.0 g/kg/day to comparison groups. Two intervention groups received personalized advice and protein-enriched foods to reach at least 1.2 g/kg/day; one group also received timing advice. Compared with control, the combined intervention groups improved their 400-meter walk time by about 12 seconds; the uncertainty range ran from roughly 3 to 22 seconds. Leg-extension strength also improved. Grip strength, body composition, other performance measures and quality of life did not differ. COVID-19 delayed some final testing, adding a practical trial limitation.

It was one EU-funded trial in a selected, relatively mobile group with low intake; severe kidney disease and several other conditions were excluded. Its mixed outcomes support further testing, not a universal new requirement.

If you’re living with a long-term condition or recovering

For people with long-term conditions, the 2025 overview rated the small gains in muscle mass and strength among people with long-term conditions as medium certainty. But the studies covered different long-term conditions, and the underlying reviews were mostly low or critically low quality, so the result should not be treated as one effect that applies equally to every diagnosis.

The hip-fracture finding needs still more care. It came from one older Cochrane review. In its high-protein comparison, the combined outcome of death or complications was an estimated 22% lower, with an uncertainty range from 5% to 35% lower, but the evidence was graded very low quality and was driven by limited trials. Broader oral multinutrient supplements contained calories, protein, vitamins and minerals, so their complication signal cannot be credited to protein alone; mortality was not clearly reduced.

PROT-AGE sets its highest range, 1.2 to 1.5 g/kg, for this group. The 2022 ESPEN practical guideline on nutrition in older people, from the European Society for Clinical Nutrition and Metabolism, recommends routine malnutrition screening for all older people, so that any risk is spotted early. A hospital stay, surgery or a new diagnosis is a reasonable time to ask whether that screening has happened.

What could be lost by combining different long-term conditions into one protein recommendation?

If you’re trying to lose weight

Weight loss after 60 can take muscle with it. The ESPEN guideline says weight-loss diets should be considered only for older people with obesity and weight-related health problems, and only together with physical exercise. It adds that older people should generally avoid restrictive diets.

ESPEN’s restriction reflects concerns about nutritional and functional losses during weight reduction in older adults. How to preserve muscle through exercise is covered in Prevent Muscle Loss After 50.

What if you have kidney disease?

Kidney disease is one situation where general high-protein targets can be inappropriate. The current 2024 Kidney Disease: Improving Global Outcomes (KDIGO) guideline suggests 0.8 g/kg/day for adults with chronic kidney disease (CKD) stages G3–G5, spanning moderate to advanced loss of kidney function, and advises those at risk of progression to avoid more than 1.3 g/kg/day. It also cautions against low-protein diets in people whose metabolism is unstable during illness and emphasizes the risks of malnutrition and age-related muscle loss. Dialysis can raise protein needs. Guidance from NIDDK is covered in Protein Needs After 50. A nephrologist or renal dietitian can set a specific target.
