Why Women Need More Protein (and Creatine) After 35
There's a quiet shift that happens somewhere in your mid-30s. You're not doing anything differently — same workouts, same diet, same routine — but your body starts responding differently. Recovery takes a little longer. Strength feels harder to hold onto. And if you're paying close attention, you might notice you don't quite look or feel the way you did a few years ago, even though nothing dramatic has changed.
This isn't in your head, and it isn't really about ageing “badly.” It's muscle — and it's one of the most consistent, well-documented shifts your body goes through in this stage of life. It's also one of the most responsive to what you do about it, starting with what you eat.
The muscle loss nobody warns you about
From around your mid-30s, most people begin to lose a small amount of lean muscle mass each year — a process that speeds up through your 40s and beyond. It's gradual enough that you don't notice it happening day to day, but it adds up quietly in the background.
Left unsupported, this steady decline doesn't just affect strength. Muscle plays a role in how your metabolism functions, how your body handles blood sugar, and how well you recover from everyday activity — not just workouts, but things like carrying groceries, keeping up with kids, or getting up off the floor without thinking about it. It's also closely linked to bone health, which becomes an increasingly important part of the picture through midlife.
The frustrating part is that nobody really tells you this is coming. Muscle loss doesn't get anywhere near the airtime that other midlife changes do, even though it's happening to almost everyone, almost silently, from decades earlier than most people assume.
Why your protein needs are changing
Protein has always mattered, but the amount your body actually needs to maintain muscle increases as you get older. That's partly because your body becomes less efficient at using protein to build and repair muscle tissue as the years go on — sometimes called “anabolic resistance.” In practice, it means the same amount of protein that used to be enough may no longer cut it, and spreading protein intake more evenly across the day tends to matter more too.
Not all protein does the same job here either. Leucine, one of the three branched-chain amino acids (BCAAs), plays an outsized role in actually switching on muscle protein synthesis — the process your body uses to repair and rebuild muscle. A protein source that's genuinely rich in leucine works harder for you than one that just ticks the “protein” box on a label.
This is also where quality and format start to matter. A highly filtered whey protein isolate — the kind that's been through extra processing to strip out lactose and sugar — gives you a cleaner, easier-to-digest source of protein, without the heaviness or bloat that can come with less refined blends. It tends to mix clearer and lighter too, which matters more than people expect when you're trying to build a genuine daily habit rather than push through a chore.
Creatine isn't just for the gym
If protein is the ingredient most women expect to hear about, creatine is usually the one that raises an eyebrow. It's spent years being associated almost exclusively with bodybuilders and gym culture, which is a shame — it's actually one of the most well-researched supplements available, and a growing body of research is specifically looking at its role in women's health, including through the midlife transition.
Beyond strength and exercise performance, creatine plays a role in how your muscles produce and use energy at a cellular level. That matters even if lifting heavy weights isn't part of your routine — it's part of why creatine is increasingly being looked at for everyday energy and recovery, alongside strength.
The form and purity matter here too. Creatine monohydrate in its purest, most refined form — fine in texture, low in impurities — is the version with the strongest research behind it, and the one your body can actually use efficiently.
What to actually look for in a protein + creatine blend
If you're looking to support muscle, strength and energy through food or supplementation, a few things are worth paying attention to:
- A protein source that's genuinely high in leucine and BCAAs, not just protein in name
- Low lactose and sugar, so it's easy on digestion and doesn't undo the point of a “clean” daily habit
- Creatine in its purest form, with minimal impurities
- Something that mixes easily and tastes good enough that you'll actually finish it, every single day, without it feeling like a task
It sounds simple, but a lot of products on the market miss at least one of these — usually taste, or purity, or both, which is often why so many good intentions end up unfinished in the back of a cupboard.
Where Salus fits in
This is exactly the thinking behind Women's Essential+ Daily Blend. It combines an extra-filtered whey protein isolate — naturally low in lactose and sugar, high in BCAAs and leucine — with the purest form of creatine available, in a clean, clear protein water rather than a thick, milky shake. It's designed to mix into your day easily, not add another chore to it.
Muscle isn't something you need to chase with intensity or perfection. It responds to consistency — small, daily inputs that add up over time. Supporting it now, rather than waiting until you notice it's gone, is one of the simplest things you can do for how you feel, move and function through this stage of life and beyond.
Frequently asked questions
Can women take creatine?
Yes. Creatine is one of the most well-researched supplements available, and a growing body of research is looking specifically at its role in women's health, including through the midlife transition.
Is creatine only useful if I lift heavy weights?
No. Beyond strength and exercise performance, creatine plays a role in how your muscles produce and use energy at a cellular level, which is why it's increasingly looked at for everyday energy and recovery too — not just training.
Why do protein needs increase with age?
Your body becomes less efficient at using protein to build and repair muscle as the years go on — sometimes called “anabolic resistance” — so the amount that used to be enough may no longer be, and spreading protein more evenly across the day tends to matter more.
