This Surprising Gym Supplement Actually Makes Your Brain Better

How I 10x’d My Focus and Intensity in Just 30 Days

I thought I was doing everything right: no booze, no cigarettes, barely any caffeine, solid sleep, regular workouts.

And yet - I had no idea my brain was still running at half power.

Then I listened to a podcast on optimum brain health with Louisa Nicola.

This changed everything.

Somehow, I’ve managed to go from “really good focus” to excellent focus - and a much higher throughput given my limited working hours.

What changed?

Since listening to that podcast, I’ve been taking Creatine Monohydrate every day.
And let me tell you: it has been a game-changer.

I’m Not a Scientist

But I decided to run an experiment on myself. I took between 3–6g of Creatine Monohydrate every day for the last 30 days.

I kept everything else exactly the same.

I continued meditating daily, kept the same exercise routine, and didn’t change my nutrition or sleep patterns (still getting broken sleep tending to toddler Blueberry - not her real name). My stress levels stayed the same.

And yet - I have more clarity of thought. At first, it was quite noticeable. Now, it just feels natural.

But I did skip a day when I went to visit my sister overnight. That day, I felt incredibly groggy and foggy, which I guess was my natural state without the creatine.

What Is It?

I always used to associate creatine with bodybuilders.

At university, I met people who took it, and I managed to persuade them otherwise because there were so many apparent side effects (that was well over 20 years ago).

Research has come on leaps and bounds since then.

Creatine is a natural compound made of three amino acids — arginine, glycine, and methionine.

Your body produces it on its own, and you also get small amounts from foods like red meat and fish.

Inside your cells, creatine helps rapidly produce ATP (adenosine triphosphate), the molecule your body and brain use for quick bursts of energy.

That’s why it's famous in the gym world — but it's just as crucial for brain cells firing efficiently during thinking, learning, and memory tasks.

While there are benefits for increasing muscle performance, there are now strong studies showing that a daily dosage of creatine actually helps your brain operate more efficiently.

And get this: there are NO negative side effects.

Because the brain naturally produces creatine, it’s a complementary supplement to take for optimum brain health.

It Can Help With:

Better Memory Recall

If you’re the type who forgets where you left your keys (or your thoughts mid-sentence), creatine might be your new best friend. Studies show it helps improve short-term and working memory - your brain’s ability to hold on to and use info in real-time.

A 2022 meta-analysis found creatine made a noticeable difference in memory, especially for older adults and people with lower natural creatine levels (like vegetarians). Another 2024 review confirmed these results, calling memory support one of creatine’s clearest brain benefits.

Faster Thinking, Sharper Focus

Ever feel like your brain is lagging like a slow-loading tab?

Creatine seems to speed things up. People who take it daily have been shown to respond quicker on mental tasks and stay more alert and attentive during long periods of focus.

It might help with:

• Faster reaction times (great for gaming or high-pressure jobs)

• Staying focused during long study/work sessions

• Improved mental stamina

More Resilience Under Stress (Like Sleep Deprivation)

Here’s where it gets interesting: creatine doesn’t just help when you’re well-rested - it might be even more useful when you’re exhausted.

In one study, participants who stayed up for 24 hours performed significantly better on thinking tasks if they had taken creatine. They even felt less cranky and foggy compared to the placebo group.

So if you’ve got a big deadline, exam, or newborn baby, creatine might just help you survive with your sanity intact.

Possible Boost to Reasoning & Problem-Solving

Some research hints that creatine may support fluid intelligence - your ability to think on your feet and solve problems without relying on past knowledge.

One study even showed people did better on abstract reasoning tests after taking creatine, especially if they weren’t getting much from their diet.

That said, this area is still being explored, some reviews say the evidence is mixed.

General Brain Energy & Protection

Okay, this one’s more behind-the-scenes: creatine boosts your brain’s energy reserves by topping up something called phosphocreatine, which your brain cells use for fast fuel.

This doesn’t make you instantly smarter, but it means your brain can handle heavy workloads more efficiently and might even stay healthier over time.

Is Creatine the New Productivity Hack?

It’s no magic pill, but daily creatine may be a simple, science-backed way to support your focus, memory, and mental resilience, especially when you're tired, stressed, or pushing yourself hard.

It’s cheap, safe, and already has a massive safety record in sports and clinical studies.
Just 3–5 grams per day (about a teaspoon) is enough to get the benefits over time - no need to "load" unless you want faster results.

While the short-term wins like sharper focus and better memory are huge, the real magic might be what creatine does for your brain in the long run.

It's not just about feeling more energized today - it could be about staying sharper, longer, and keeping your mind strong as you age.

Future-Proof Your Brain

As a bonus, creatine isn’t just helping you crush today’s to-do list, it might also help future-proof your brain.

Studies are starting to show that by boosting brain energy, creatine could help ward off age-related cognitive decline like dementia and Alzheimer’s.

It's early days, but considering how safe and inexpensive it is, daily creatine might just be the ultimate low-key brain insurance.

TL;DR: Here’s Why Creatine Might Just Be the Ultimate Productivity Upgrade

• Creatine = less brain fog, better memory for names, facts, and tasks.

• Think of it as extra fuel for your mental CPU.

• Creatine helps your brain stay strong when you're running on fumes.

• Could help with quick thinking, especially during mentally demanding tasks.

• More brain energy = less mental fatigue and better long-term focus.

It’s cheap, it’s safe, and it could make you sharper today and tomorrow.
Honestly, why not?
