How much protein for a woman over 50
Protein targets for women over 50 from the PROT-AGE recommendations, why spreading it across the day matters, and what a day of ordinary food looks like.

Why the adult figure is not the older adult figure
The familiar 0.8 grams of protein per kilogram of body weight per day was set to prevent deficiency, not to maintain muscle in someone who is sixty and training. The PROT-AGE expert group recommends more for older people, in the region of 1.0 to 1.2 grams per kilogram per day for healthy adults over 65, and 1.2 to 1.5 for those who are ill or doing regular exercise, unless kidney disease makes that inappropriate. For a woman of 65 kilograms, that is roughly 65 to 100 grams a day rather than 52.
Muscle is the reason
Strength, not size, is at the centre of the European definition of sarcopenia, and losing it is what turns an ordinary fall into a fracture and a fracture into a lost year. Training gives the signal to keep muscle; protein gives the material. One without the other produces half a result, which is why women who eat well but never lift, and women who lift but eat like a bird, both plateau.
Spread it, do not stack it
Older muscle responds less to a small dose of protein than young muscle does, so three meals of roughly 25 to 30 grams each work better than a token breakfast and a large dinner. Breakfast is where most women are short: toast and coffee is close to zero. Adding eggs, Greek yoghurt, cheese or beans to that one meal often closes half the daily gap on its own.
What 25 to 30 grams looks like on a plate
Three eggs. A tin of tuna. A 120 gram chicken breast. 150 grams of Greek yoghurt plus a spoon of nuts. 200 grams of cottage cheese. A 150 gram salmon fillet. For plant-based days: 150 grams of tofu, a large bowl of lentils, or beans plus wholegrain bread, which together supply the range of amino acids that either one alone would miss.
| Food | Portion | Protein |
|---|---|---|
| Eggs | 3 large | 19 g |
| Greek yoghurt | 200 g | 20 g |
| Chicken breast | 120 g | 28 g |
| Tinned tuna | 1 tin, drained | 25 g |
| Tofu | 150 g | 18 g |
| Lentils, cooked | 300 g | 27 g |
Around your training
Protein within a few hours of a strength session is the useful window, not the twenty minutes that supplement marketing invented. If you train in the morning, a proper breakfast covers it. If you train in the evening, dinner does. Powders are convenient and not required; they are food in a tub, priced by the marketing on the label.
When to check with a doctor
If you have kidney disease, or you have been told to limit protein for any reason, these figures do not apply to you and the target must come from your clinician. If you are losing weight without trying, or your appetite has fallen away, that is worth a consultation rather than a bigger protein target.
Questions
How much protein should a woman over 50 eat?
The PROT-AGE recommendations suggest 1.0 to 1.2 grams per kilogram of body weight daily for healthy older adults, and 1.2 to 1.5 for those who are ill or exercising regularly, unless kidney disease makes that inappropriate.
Do I need protein powder?
No. Powders are convenient, not necessary. Eggs, dairy, fish, poultry, tofu and legumes cover the same ground at a lower price.
Does it matter when I eat protein?
Spreading it across three meals of roughly 25 to 30 grams works better than one large evening portion, because older muscle responds less to small doses.
