4 Signs You’re Not “Just Getting Old” – New Research on Healthy Aging

Written by Lean Greens Crew | Evidence-Based

At a certain point in life, a quiet narrative starts to creep in.

You feel a bit more tired than you used to. Muscle seems harder to hold onto. Sleep isn’t as deep. Names, words, and little details take longer to surface.

Most of us brush it off with the same phrase:

“I guess that’s just getting old.”

It sounds sensible. Even responsible.

But a growing body of research suggests something more hopeful, and more practical.

A comprehensive critical analysis published in the National Library of Medicine makes a compelling case that healthy aging isn’t about luck or genetics.

It’s about maintenance.

And more specifically, it’s about whether your body is still getting the inputs it needs to function at the level you expect.

The One Big Thing Most People Miss About Aging

We come back to this idea again and again because it explains so much frustration.

The Rule of 1.

If something feels like an inevitable decline but doesn’t happen evenly across all people, there’s usually one underlying driver.

In the case of aging, the research points to what we’ll call The Input Deficit.

What is the Input Deficit?

As we age, our bodies become:

• Less efficient at digesting food
• Slower at absorbing nutrients
• Less responsive to the same protein and micronutrient intake

In other words, the same diet that worked at 35 no longer delivers the same result at 55.

The study highlights a counter-intuitive but critical point:

Older adults often need more of certain nutrients just to maintain the same baseline function as younger adults.

That doesn’t mean you’re broken.

It means the goalposts have moved.

And if you don’t adjust your inputs, your output naturally drops.

4 Signs It’s Not “Age”… It’s Under-Fueling

1. The Muscle Math Problem (It’s Not Just Protein)

One of the most overlooked aspects of aging is muscle loss.

Not dramatic muscle wasting, but gradual, silent decline.

This process has a name: Sarcopenia.

Research shows that from around age 50 onwards, adults lose roughly 1–2% of skeletal muscle per year.

That might not sound like much.

But over a decade, it adds up to:

• Reduced strength
• Slower metabolism
• Higher fall risk
• Loss of independence

Why “eating a bit more protein” isn’t enough

Most people respond sensibly:

“I’ll eat more chicken.”

The problem?

The study highlights anabolic resistance.

As we age, muscle tissue becomes less responsive to amino acids. That means:

• You absorb less
• You build less
• You need more input for the same effect

The research suggests older adults may require 1.2–1.6g of protein per kg of bodyweight per day, significantly higher than standard recommendations.

The hidden gem: Creatine

This is where the study becomes very clear.

Creatine isn’t just for athletes.

In adults over 50, creatine supplementation is associated with:

• Increased muscle mass
• Improved strength
• Better functional performance

Most importantly, it helps protect against the deconditioning that leads to falls and frailty.

The fix

Stop thinking of creatine and protein as “gym supplements”.

They’re maintenance tools.

If strength and independence matter to you long-term, these aren’t optional extras.

2. The Sleep Quality Trap (Why Melatonin Isn’t the Answer)

Sleep is one of the first things people notice changing with age.

You might:

• Fall asleep later
• Wake up earlier
• Feel less refreshed
• Drift in and out of light sleep

Fatigue builds. Focus drops. Everything feels harder.

Why melatonin is a problem

Many people turn to melatonin because it’s easy and marketed as “natural”.

But the study raises a red flag.

Because melatonin supplements are poorly regulated, analyses have found:

• Huge variation in actual dose
• Presence of serotonin (a controlled substance) in some products

That creates unnecessary risk, especially for long-term use.

What the research points to instead: Magnesium

Magnesium works differently.

It doesn’t force sleep.

It supports the nervous system by:

• Regulating neurotransmitters
• Supporting relaxation pathways
• Improving sleep onset and efficiency

The review highlights that magnesium supplementation has been shown to:

• Improve subjective sleep quality
• Reduce time taken to fall asleep
• Reduce early morning waking in older adults

The fix

Prioritise minerals over hormones.

Magnesium supports sleep as a system, not a switch.

That’s how you make sleep better without creating dependency.

3. The Brain Barrier (Inflammation Is the Real Enemy)

When people worry about aging, what they’re often afraid of isn’t wrinkles.

It’s cognitive decline.

Memory slips. Brain fog. Loss of sharpness.

The study highlights something crucial here:

Chronic inflammation is a major driver of cognitive decline.

Inflammation damages brain tissue over time. That’s why dietary patterns like the Mediterranean diet are associated with a 33% lower risk of cognitive decline.

The role of Omega-3s

Omega-3 fatty acids, particularly EPA and DHA, are structural components of brain tissue.

The research links higher Omega-3 intake with:

• Better global cognitive performance
• Reduced inflammatory markers
• Support for neuronal repair

The study also highlights the role of B vitamins, which help lower homocysteine, a compound associated with brain atrophy.

The fix

Your brain isn’t abstract.

It’s physical tissue.

If you don’t feed it anti-inflammatory fats and micronutrients, it can’t maintain itself.

This isn’t about “brain boosting”.

It’s about preventing erosion.

4. The Absorption Cliff (Why Eating Well Stops Working)

This may be the most important insight in the entire review.

As we age, digestion changes.

Specifically:

• Stomach acid production declines
• Enzyme output drops
• Nutrient activation becomes less efficient

The study notes that reduced stomach acid directly impairs absorption of:

• Vitamin B12
• Amino acids
• Protein-based nutrients

This creates a frustrating situation.

You can:

• Eat well
• Choose quality food
• Follow all the advice

And still fall short because your body simply can’t extract what it needs.

The fix

You must prioritise bioavailability.

That means:

• Hydrolysed proteins instead of whole ones
• Enzyme-assisted formulas
• Easily digestible formats

Healthy aging isn’t about eating more.

It’s about absorbing better.

The Problem With “Doing Everything Right”

When you step back, the study paints a demanding picture.

To age well, older adults need:

• More protein
• Creatine for muscle
• Magnesium for sleep
• Omega-3s for the brain
• Digestive support for absorption

Trying to manage this with:

• Separate pills
• Multiple powders
• Complicated routines

Is a recipe for burnout.

And burnout leads to inconsistency.

Supplements We Suggest (And Why)

This is where we applied the Rule of 1 again.

The problem wasn’t motivation. It wasn’t discipline.

It was fragmentation.

So instead of selling isolated supplements, we built a daily system that covers the core inputs highlighted in the research.

1. The Morning Builder: Collagen Greens

Collagen Greens is designed to support structural maintenance, not trends.

Sarcopenia defence

Each scoop includes:

• 4g Creatine Monohydrate

Exactly what the research highlights as beneficial for adults over 50 to maintain strength and function.

Absorption support

Because digestion changes with age, we include:

• DigeZyme, a multi-enzyme complex

This helps ensure the nutrients you consume actually get used.

Structural support

We also include:

• Bovine collagen peptides

Supporting joints, connective tissue, and skin, areas that naturally degrade with time.

2. The Brain Shield: Good Fats (Omega-3)

Good Fats is designed to support low-inflammation aging.

• High-potency EPA and DHA
• 75% concentration to avoid filler fat
• Supports cognitive tissue maintenance

This aligns directly with the research linking Omega-3s to cognitive performance.

3. The Night Repair: Drift Off

Instead of melatonin, Drift Off uses:

• Magnesium Bisglycinate

A highly absorbable form shown to support:

• Sleep efficiency
• Faster sleep onset
• Better rest quality

Without hormonal interference.

The Bottom Line

Aging is inevitable.

Decline isn’t.

If you feel:

• More tired than you should
• Weaker than expected
• Foggy rather than sharp

It’s not a personal failure.

It’s likely an input problem.

Give your body what it now requires, not what it used to get away with.
