Protein needs rise with age rather than falling, and after 50 the gap between the RDA and what actually protects muscle widens sharply. Adults over 65 are advised to take at least 1.0 to 1.2 g per kg.
This article covers why ageing muscle responds less to the same protein dose, what that means for women through and after menopause, and how much of the standard advice needs adjusting.
Quick Answer: Protein After 50
Take at least 1.0 to 1.2 g per kg daily after 65, which is 65 to 78 g for a 65 kg adult. Aim for 25 to 30 g per meal rather than one large dinner, and pair it with 2 resistance sessions a week.
Key Takeaways
- Adults over 65 need at least 1.0 to 1.2 g per kg daily
- Muscle mass falls 3 to 8% per decade after age 30
- Ageing muscle needs 25 to 30 g per meal to respond
- Protein alone does little without at least 2 resistance sessions weekly
- Menopause accelerates muscle and bone loss for roughly 5 years
- Appetite typically falls by 20 to 30% with advancing age

Muscle becomes less responsive to protein as you get older, a phenomenon called anabolic resistance. The same 20 g serving that produced a strong building response at 25 produces a noticeably weaker one at 70, so the amount required per meal goes up. The underlying calculation does not change, only where you land inside it, and it is set out in what protein does and how much of it you need.
This is not a small technical detail. Muscle mass declines by roughly 3 to 8% per decade after 30, and that rate accelerates after 60 unless it is actively defended.[1]Dietary Protein Needs and Skeletal Muscle in Older Adults — Journals of Gerontology View source
- Anabolic resistance means the same dose triggers a weaker response.
- Per-meal threshold rises from about 20 g to 25 to 30 g.
- Appetite falls by 20 to 30%, so intake often drops as needs rise.
- Recovery slows, raising demand after illness or injury.
The PROT-AGE position paper recommends at least 1.0 to 1.2 g per kg daily for healthy older adults, well above the 0.8 g per kg RDA, specifically to defend muscle mass and physical function.[2]Optimal Dietary Protein Intake in Older People — Journal of the American Medical Directors Association View source
Where a shortfall already exists, supplementing has its clearest measurable effect in exactly this group rather than in younger people already eating enough.[3]Effects of Protein Supplements on Muscle Mass, Strength and Power — Sports Medicine View source
What the Numbers Look Like
The practical figures are more approachable than the multipliers suggest. Most people in this group are aiming for something between 65 and 100 g a day, which three solid meals can deliver without any supplement.
| Body weight | RDA (0.8) | Recommended (1.0–1.2) | Per meal across 3 |
|---|---|---|---|
| 55 kg / 121 lb | 44 g | 55–66 g | 18–22 g |
| 65 kg / 143 lb | 52 g | 65–78 g | 22–26 g |
| 75 kg / 165 lb | 60 g | 75–90 g | 25–30 g |
| 85 kg / 187 lb | 68 g | 85–102 g | 28–34 g |
Notice the gap between the RDA column and the recommended one. For a 75 kg adult that difference is 15 to 30 g a day, which is roughly one extra serving of Greek yogurt or fish. The broader calculation is explained in working out your grams per day.
What Changes for Women Around Menopause
Oestrogen has a protective effect on both muscle and bone, and its decline through perimenopause and after removes part of that protection. The result is a period of several years where losses accelerate noticeably.
Protein does not replace hormones, but it does supply the raw material that resistance training uses to slow the decline.
| What changes | Why | What helps |
|---|---|---|
| Faster muscle loss | Oestrogen decline plus anabolic resistance | 1.0–1.2 g/kg and resistance training |
| Bone density falls | Oestrogen supports bone turnover balance | Protein, calcium, vitamin D, loading |
| Body composition shifts | Fat redistributes centrally | Protein for satiety, training for muscle |
| Recovery slows | Repair capacity declines with age | Even 25–30 g protein across meals |
Bone is often overlooked in this conversation. Roughly 50% of bone volume is protein by structure, and the collagen matrix that mineral attaches to depends on adequate intake.
Why Training Is Not Optional Here
Protein alone produces very little change in older adults. It supplies material, and resistance training supplies the signal that tells the body to use it rather than discard it.
Two sessions a week is enough to shift the outcome substantially, and it does not require a gym membership or heavy loading.
- 2 sessions weekly is the practical minimum for a measurable effect.
- Bodyweight movements such as sit-to-stand count as resistance work.
- 8 to 12 weeks is the usual window before strength changes show.
- Progression matters more than intensity at any single session.
Where appetite makes hitting the target difficult, our 12 oz chocolate whey adds around 20 g in a form that does not require cooking or a large meal.
Getting There When Appetite Has Dropped
Falling appetite is the practical obstacle, not motivation or knowledge. When total food intake shrinks by 20 to 30%, protein tends to fall further because it is the most filling macronutrient and gets displaced first.
The answer is to raise protein density rather than meal size, so every mouthful carries more. It helps to know the target first, and you can calculate your daily protein target with age and build already factored in.
- Start each meal with the protein portion rather than finishing with it.
- Choose dense sources: Greek yogurt at 20 g, cottage cheese at 25 g per cup.
- Add milk powder or a scoop to soups, porridge and mashed potato.
- Treat a shake as a between-meal drink rather than a meal replacement.
For anyone avoiding dairy, our Remedy's plant protein powder delivers 22 g per scoop and mixes into the same foods without the lactose question.
Frequently Asked Questions
What is a good amount of protein for a 50 year old woman?+
Aim for 1.0 to 1.2 g per kg of body weight, which is 65 to 78 g daily for a 65 kg woman. If she is training or losing weight, 1.2 to 1.6 g per kg is more appropriate, taking it to 78 to 104 g. The RDA figure of 52 g is a floor rather than a target at this age.
Which protein is best for a 50 year old woman?+
Whichever one gets eaten consistently. Greek yogurt at 20 to 23 g per cup, eggs, fish, and cottage cheese at around 25 g per cup are all excellent because they are dense and easy to eat. Whey has the highest leucine content per serving, which matters more with age since the per-meal threshold rises.
Should a 50 year old woman take protein powder?+
Only if food is not getting her to 1.0 to 1.2 g per kg. Powder is a convenience, not a requirement, and whole foods bring calcium, vitamin D and fibre alongside the protein. It becomes genuinely useful when appetite has fallen or when breakfast routinely delivers under 10 g.
What are the signs of protein shortfall in older adults?+
The 5 most common are losing strength or finding stairs harder, slow recovery from illness or minor injury, constant hunger between meals, hair thinning, and nails that split easily. In older adults, difficulty rising from a chair without using the arms is a particularly telling early sign of muscle loss.
Does protein help with bone density?+
Yes, and it is often overlooked. Around 50% of bone volume is protein, forming the collagen matrix that mineral attaches to. Older research suggested high protein leached calcium from bone, but that has not held up. Adequate protein alongside calcium, vitamin D and weight-bearing exercise supports bone rather than harming it.
Can you build muscle after 60?+
Yes. Studies consistently show people in their 60s, 70s and beyond gaining measurable strength and muscle from resistance training. The response is slower than at 30 and requires more protein per meal, around 25 to 30 g, but the direction of change is the same. Expect visible progress in 8 to 12 weeks.
How much protein at breakfast for older adults?+
Aim for 25 to 30 g, which is where most older adults fall shortest. A typical breakfast of toast and tea supplies 6 to 8 g, well below the threshold needed to trigger a building response. Two eggs plus Greek yogurt, or porridge made with milk and a scoop of protein, closes that gap comfortably.
Is too much protein dangerous for older adults?+
For those with healthy kidneys, intakes up to 2 g per kg have been studied without evidence of harm, and the far more common problem in this age group is eating too little. Anyone with reduced kidney function, which becomes more prevalent with age, needs an intake set by their doctor rather than a general guideline.
Do women need less protein than men?+
Not proportionally. The calculation runs on body weight, so a 65 kg woman and a 65 kg man arrive at the same figure of 65 to 78 g at 1.0 to 1.2 g per kg. Women often need less in absolute terms simply because average body weight is lower, not because the requirement per kilogram differs.
Does protein help with menopause weight gain?+
Indirectly, in 2 ways. It is the most satiating macronutrient, so raising it reduces total intake without conscious restriction. It also preserves muscle, which keeps resting energy expenditure higher. Neither reverses the hormonal shift, but together with resistance training they change how body composition responds to it.
How long before more protein makes a difference?+
Appetite and energy changes appear within 1 to 2 weeks. Strength gains take 8 to 12 weeks of consistent intake paired with resistance training, and measurable muscle change usually needs 12 weeks or more. Grip strength and the ability to rise from a chair unaided are the easiest markers to track at home.
