Protein for Women Over 35: How Much You Really Need & How to Hit It

Protein is the nutrient I talk about most with my female clients, and the one most women, especially over 35, aren't getting enough of. As we move through our late thirties, forties and into perimenopause, protein stops being a "gym thing" and becomes essential for holding onto muscle, protecting our bones, balancing hormones and staying strong and lean. Here's exactly how much protein you need, why it matters more after 35, and simple ways to hit your target every day, including the one plant-based protein I personally use.

Why Protein Matters More After 35

Protein is involved in the repair and rebuilding of tissues, in making hormones, and in supporting your immune system. After around 35, three things start working against us: muscle naturally declines from our mid-thirties unless we actively work to keep it, we digest and use protein less efficiently as we age so we need a bit more to get the same benefit, and perimenopause changes everything, with shifting hormones making it easier to lose muscle and bone, so adequate protein alongside resistance training becomes protective for metabolism, body composition and long-term bone health. In short: eating enough protein in your late thirties and beyond isn't about bulking up, it's about staying strong, functional and lean for decades to come.

How Much Protein Do Women Actually Need?

The official baseline for sedentary, generally healthy adults is about 0.8g of protein per kg of body weight, just enough to prevent deficiency. That works out to roughly 55g a day for a 68kg (150lb) person, or 72g for a 90kg (200lb) person. But that's the minimum to avoid problems, not the amount to thrive. For active women over 35 who want to maintain muscle, support recovery and protect bone, the research points higher, around 1.2 to 1.8g per kg of body weight. A practical target for most active women over 35 is around 1.5g per kg, adjust up if you train hard or are building muscle, and down toward 1.2g if you're lightly active.

My Own Protein Target (A Worked Example)

I'll use myself as the example, because the maths is the part people find confusing. I weigh 45kg, and I aim for around 1.5g per kg, so my daily target is about 67.5g of protein (45 x 1.5 = 67.5g). I hit it by anchoring every meal around protein and fibre and topping up where food falls short, including adding about 20g of plant-based protein powder to my morning porridge. Work out your own number from the table above, then build your day around it.

When You Might Need More, or Less

Adjust upwards if you train hard and frequently or have a physically demanding job, are injured, unwell, or recovering from surgery, are older (we digest protein less efficiently and need more to meet the same requirement), or are under chronic physical stress or losing protein for another reason. Adjust downwards only if advised: some medical conditions (for example certain kidney or metabolic conditions such as PKU) require a lower-protein diet. If that's you, always follow the guidance of your doctor or dietitian rather than a general rule.

How to Actually Hit Your Protein Target

Anchor every meal with protein, aiming for roughly 25 to 35g per meal across three meals to naturally land near most targets, since spreading protein through the day helps your body use it better than one big hit. Fix breakfast first, it's the meal women most often skimp on, with eggs, Greek yoghurt, or protein stirred into porridge or a smoothie making the biggest difference. Go food first, since whole-food protein comes with other nutrients you want.

Do You Actually Need a Protein Powder?

No, not everyone does, and I'm the first to say so. If you comfortably reach your target through food, you don't need a powder. But it earns its place when hitting your number from food alone is genuinely hard: busy mornings, smaller appetites, plant based diets, or a naturally high muscle mass that pushes your requirement up. In those cases, a scoop is simply an efficient, convenient way to close the gap.

How to Choose a Protein Powder (and the One I Use)

Look for a complete amino acid profile (all nine essential amino acids, so it actually supports muscle repair; blends of pea, rice and seed proteins do this well), minimal clean ingredients (no unnecessary fillers, gums, thickeners or artificial sweeteners), and a form that fits your routine (unflavoured powders are the most versatile because they disappear into porridge, smoothies and baking). The one I personally use is Form Pureblend Protein, an unflavoured, unsweetened vegan blend of organic pea protein isolate, brown rice and pumpkin seed protein, with a complete amino acid profile and no fillers or sweeteners. Every 20g tablespoon delivers 15g of protein, so it slots straight into my porridge without changing the taste. It's a UK B-Corp brand in plastic-free packaging, and a 520g pouch is around £27. It ticks every box I look for: complete, clean and genuinely versatile.

A Simple High-Protein Day (Around 70g)

Breakfast: porridge with 20g Form Pureblend protein + berries, ~20g.
Lunch: big salad with 150g chicken or a tofu and lentil bowl, ~30g.
Snack: edamame handful, ~15g.
Dinner: salmon or beans with vegetables, ~25g.

Small, repeatable choices, not a total diet overhaul, are what get you to your number consistently.

FAQ

How much protein does a woman over 35 need per day?
As a general guide, active women over 35 do best on around 1.2 to 1.8g of protein per kg of body weight, roughly 1.5g/kg for most. For a 60kg woman that's about 90g a day. The 0.8g/kg official figure is only the minimum to prevent deficiency, not an optimal target.

Is plant based protein enough for women?
Yes, if it's a complete amino acid blend. Combinations like pea, brown rice and pumpkin seed protein provide all nine essential amino acids, making them a solid alternative to whey for muscle maintenance.

Do women over 35 need a protein powder?
Not necessarily. If you hit your target through food, you don't need one. A powder simply makes it easier to close the gap on busy days, plant-based diets or smaller appetites.

What is the best time to eat protein?
Spread it across the day, roughly 25 to 35g per meal, rather than one large serving. Prioritising protein at breakfast is the single change that helps most women hit their daily total.

Does eating more protein make women bulky?
No. Protein supports muscle maintenance and tone, not bulk. Combined with strength training it helps you look leaner and stronger, not bigger.
