Most adults over 50 need more protein than the standard RDA of 0.8 g/kg — not to chase a number, but to hold onto the muscle, bone, and independence that age steadily chips away. Expert groups now recommend 1.0 to 1.2 grams per kilogram a day for healthy older adults, yet many people are not even hitting the old floor. And if you lift, the target runs higher still — because for an aging body, the thing that breaks down most often is not the muscle. It is recovery falling behind the training load.
Why protein needs climb with age
Starting in your 50s and picking up speed after 65, the body loses muscle — a process called sarcopenia. This is not about looking softer. Muscle loss drives weakness and poor balance, raises the risk of falls and fractures, erodes independence, and tracks with higher mortality. Nearly half of adults over 80 are meaningfully affected, and inactivity, illness, and under-eating all speed it up.
Aging also dulls the body’s response to protein. Older muscle needs a bigger dose — roughly 25 to 40 grams in a meal — to trigger the same muscle-building response a younger person gets from less, an effect called anabolic resistance. Protein does more than build muscle, too: it supports bone, immune function, wound healing, and recovery from illness or injury. Eat too little and you speed up the very muscle loss you are trying to avoid. Yet an estimated 40 to 50% of older adults fall short of even the 0.8 g/kg RDA, often because of a smaller appetite, dental issues, cost, or chronic illness.
What the experts actually recommend
This is not a fringe view. Two major panels — the PROT-AGE Study Group and the ESPEN Expert Group — reviewed the evidence independently and landed in the same place: healthy older adults should aim for 1.0 to 1.2 grams of protein per kilogram of body weight per day, rising to 1.2 to 1.5 g/kg for those who are ill or recovering. Both stress the same companion to it — regular resistance training. The main exception is severe kidney disease, where protein may need to be limited; that is a conversation for your own health care provider.
What this looks like on a plate
For a 70-kilogram (154-pound) adult, 1.0 to 1.2 g/kg works out to roughly 70 to 85 grams of protein a day — and it lands better spread across the day, about 25 to 30 grams per meal, rather than piled into dinner. None of the portions that get you there are unusual:
| Food | Approx. protein |
|---|---|
| Plain Greek yogurt (1 cup) | ~23 g |
| Three large eggs | ~18 g |
| Chicken breast (4 oz) | ~30 g |
| Salmon (4 oz) | ~28 g |
Dairy, eggs, meat, and fish are the easiest sources; plant proteins work but usually take larger portions. The obstacle is rarely the math — it is appetite, habits, and timing.
If you lift, the bar is higher
Everything above is the baseline for older adults in general. If you strength train, you sit at the top of that range and often past it — toward 1.2 to 1.6 g/kg — because you are deliberately asking more of your muscles and connective tissue. You break tissue down in order to build it back stronger, and that rebuild runs on protein and rest. Which points to the real issue for the older lifter.
Where recovery comes in
Most of the nagging injuries that sideline older lifters do not come from one bad rep. They come from a mismatch — training load climbing faster than the body can recover. And recovery is exactly what age works against: repair slows, muscle answers protein less readily, and many lifters are quietly under-eating protein on top of it. Close that gap and you keep training; let it widen and the aches, tweaks, and flare-ups pile up.
Managing that balance — enough load to get stronger, enough recovery to absorb it — is the heart of what we do at Performance Sport Care. Our diagnosis-guided, supervised strength approach is built to keep older athletes training hard without outrunning their recovery. If you are lifting through pain that will not settle, that mismatch is usually the first place to look.
Lifting through nagging pain that won’t settle? It’s often a load-and-recovery problem, not a reason to stop training.

How much protein should adults over 50 or 65 eat?
Major expert groups — PROT-AGE and ESPEN — recommend 1.0 to 1.2 grams of protein per kilogram of body weight per day for healthy older adults, and 1.2 to 1.5 g/kg for those who are ill or recovering. For a 70-kilogram adult that is roughly 70 to 105 grams a day, well above the 0.8 g/kg RDA, which was only meant to prevent deficiency.
Why do older adults need more protein than younger adults?
Two changes arrive with age. Muscle is steadily lost (sarcopenia), and the muscle that remains responds less to protein (anabolic resistance), so it takes a larger dose to get the same muscle-building effect. More protein, paired with resistance training, helps offset both.
Can eating more protein help prevent falls and keep me independent?
It can contribute. Falls and lost independence are driven largely by weakness and muscle loss, and protein — paired with regular strength training — helps preserve muscle and physical function. It is not a guarantee or a stand-alone fix, but it is one of the levers that matters most.
Do strength trainers over 50 need even more protein?
Yes. Strength training pushes protein needs toward the upper end of the range, around 1.2 to 1.6 g/kg per day, because training breaks tissue down to rebuild it stronger. For older lifters, falling short tends to show up as recovery lagging behind training load — a common source of nagging injury.
