Turning 40 can feel like a bit of a milestone. Suddenly, everyone seems to have an opinion about what your body should be doing, what you should be eating, how much you should be exercising, and why you apparently need to start worrying about your bones!

But does your body really need a complete overhaul just because you've reached 40?

Not quite.

The truth is, most of what your body needs after 40 isn't particularly revolutionary. You still need good food, enough protein, regular movement, quality sleep, and plenty of essential nutrients. The difference is that some of these things can become a little more important as we get older, particularly when it comes to maintaining muscle, supporting bone health, and giving your body what it needs to keep functioning well.

So, what actually changes after 40? And what should you be paying a little more attention to?

Let's Talk About Muscle

Muscle probably isn't the first thing that comes to mind when you think about healthy aging. We tend to focus on things like heart health, our diet, or keeping our minds active. Yet muscle has a huge influence on how we actually get through the day.

Think about everything your muscles do without you giving them a second thought. Getting out of a chair. Carrying the shopping. Climbing the stairs. Picking up the kids. Walking the dog. Opening a stubborn jar when nobody else in the house can manage it!

We naturally lose some muscle mass and strength as we age, which is why maintaining what we have becomes increasingly important. This is where resistance training comes in. You don't need to become a gym obsessive or start lifting enormous weights. Resistance bands, bodyweight exercises, weights, pilates, and plenty of other activities can all give your muscles a reason to keep working.

Current physical activity guidelines from the World Health Organization recommend at least 150 minutes of moderate-intensity activity each week for 18-64 year olds, along with muscle-strengthening activities on at least two days. You’ll find more information alongside recommendations for younger and older people on the WHO site.

The goal isn't necessarily to become stronger than you've ever been. It's to stay strong enough to keep doing the things you enjoy.

Protein Is Even More Important Than It Was Before

This brings us to protein.

Protein has always been important, but maintaining muscle becomes more of a priority as we get older. Your body uses protein to build and repair tissues, including muscle, so getting enough through your diet gives your body the raw materials it needs.

Research suggests that protein needs can be higher in older adults, particularly alongside regular physical activity and resistance training. An expert group from ESPEN recommends around 1.0 to 1.2 grams of protein per kilogram of body weight per day for healthy older adults. 

But don't panic if you have absolutely no idea how many grams of protein you ate yesterday. You don't have to turn every meal into a math equation. Start by looking at your plate. Is there a decent source of protein there? Eggs at breakfast, Greek yogurt, fish, chicken, lean meat, beans, lentils, tofu, nuts, and seeds can all help contribute to your daily intake.

It really is about making the food you're already eating work a little harder for you.

Your Bones Deserve Some Attention Too

Here's something else we probably don't think about enough in our 30s and 40s: our bones.

Bone health is something we often associate with much later in life, but maintaining strong bones is a long-term job. Calcium and vitamin D both contribute to the maintenance of normal bones, while weight-bearing and resistance exercise can also help support bone health.

Vitamin D is particularly interesting because it has more than one job. It also contributes to normal muscle function and the normal functioning of the immune system.

Getting vitamin D from sunlight isn't always straightforward either, particularly depending on where you live, the time of year, and how much time you actually spend outside. For some people, dietary sources and supplements may therefore become useful ways of getting enough.

This is one of those areas where looking after yourself now can be much more useful than waiting until there's a problem later.

Don't Just Eat Less. Eat Better.

There's a strange idea that getting older means we should simply start eating less and less.

Yes, our energy needs can change as we age, particularly if we're less active than we used to be. But that doesn't mean surviving on tiny portions and calling it healthy eating.

If anything, the food we do eat needs to provide plenty of nutritional value.

Think vegetables, fruit, whole grains, beans, lentils, nuts, seeds, fish, lean proteins, and other minimally processed foods. These give you vitamins, minerals, fiber, protein, and a whole range of other nutrients your body needs.

You don't need a perfect diet. You just need to make good choices most of the time.

Give Your Gut A Little Love

Fiber deserves a mention here too.

Most of us know that fiber is important for digestion, but it also plays a role in feeding the bacteria living in your gut. You can find it in vegetables, fruit, whole grains, beans, lentils, nuts, and seeds, so getting more doesn't have to involve buying a specialist “gut health” product.

The trick is to increase it gradually if your current diet is fairly low in fiber. Your digestive system may not thank you for suddenly going from very little fiber to a mountain of beans overnight!

Water matters here too. Your digestive system needs enough fluid to help things move along, so increasing fiber without paying attention to hydration isn't necessarily the best strategy.

What About B12 And Vitamin C?

This is where things can get a little confusing.

Walk into any health food store and you'll find enough supplements marketed to the over-40s to make you wonder whether you've somehow developed 14 nutritional deficiencies overnight.

You haven't.

There are certain nutrients worth keeping an eye on, though, particularly depending on your diet and lifestyle. Vitamin B12 is one of them. It supports normal red blood cell formation, the nervous system, and normal energy-yielding metabolism. Our ability to absorb the B12 naturally found in food can also change as we get older, so it's a nutrient that's worth paying attention to.

Then there's vitamin C. We tend to associate it with immune health, but it does quite a bit more than that. Vitamin C contributes to normal collagen formation, which is important for skin, bones, and cartilage. It also protects cells from oxidative stress.

The good news is that both can be found in everyday foods. Meat, fish, eggs and dairy provide B12, while fruits and vegetables are great sources of vitamin C.

For those times when getting everything you need from food isn't quite so straightforward, supplements can be a convenient addition to your routine. Our Liposomal Vitamin B12 and Vitamin C chews can easily fit into a daily routine alongside a varied diet.

The important thing is not to assume that turning 40 means you automatically need a shelf full of supplements. It's about looking at what you're actually getting, understanding what your body needs, and filling any gaps.

Your Cells Need Extra Support

There's another side of healthy aging that's a little less obvious. Our bodies naturally produce antioxidants, including glutathione, which helps protect cells from oxidative stress. Glutathione levels can also be affected by things like age, nutrition, and lifestyle.

This is one reason glutathione has become an interesting area of research around healthy aging. We're not talking about a magic “detox” solution here. Your body already has its own systems to handle everyday metabolic processes.

The idea is simply to support those natural systems.

Our Liposomal Glutathione provides glutathione in a convenient supplement form that’s rapidly absorbed by the body and can easily fit into a daily wellness routine.

Don't Underestimate Sleep

Then there's the thing we all know we should probably do more of but somehow keep finding reasons not to.

Sleep.

Sleep is part of how your body recovers. It's important for physical recovery, immune function, memory, and plenty of other processes happening behind the scenes.

Yet life gets busy. Work runs late. There's washing to put away. Someone needs a lift somewhere. You decide you're just going to watch one episode and suddenly it's midnight.

We've all been there.

Sometimes looking after yourself after 40 isn't about adding another healthy habit to an already packed schedule. It might mean taking something away. Whether it’s going to bed a little earlier, saying no to something, or taking a proper lunch break.  Those things all count too.

So, What Does Your Body Actually Need After 40?

Your body probably needs less of the complicated stuff than you think.

It needs enough protein to support your muscles. It requires regular movement and some form of strength training. It needs nutrient-dense food, plenty of fiber, and the vitamins and minerals that keep all those everyday processes ticking along.

It needs sleep. It needs recovery. It needs water. It needs a little attention. And most importantly, consistency.

You don't need to completely overhaul your life because you're 40, 45, or 49, but it can be a time to focus a little more on your health than you did before. Think of this stage of life as an opportunity to start paying a little more attention to the things your body has been asking for all along.

Looking after yourself after 40 isn't about trying to turn back the clock. It's about giving your body what it needs to keep up with the life you want to live.
