Creatine: the everyday energy nutrient for strength, performance, and the brain

Creatine is one of the most researched supplements in the world. It is best known for supporting short bursts of high-intensity effort, strength, and training performance. But it is not only a “gym supplement”. Creatine is also stored in the brain, where it helps support normal cellular energy metabolism.

That matters because both muscles and the brain run on the same energy currency: ATP. Creatine helps buffer and recycle energy in cells, which is why it’s being studied not only for performance, but also for cognition, mood, and healthy ageing.

What is creatine, and where do we get it from?

Your body makes creatine naturally, and you also get it from food, especially red meat and fish. The catch is that the amounts used in most research (and the amounts people often use for performance outcomes) are difficult to achieve consistently through diet alone.

This is why creatine monohydrate supplementation is so popular: it is a practical way to increase creatine stores without relying on very high intakes of animal foods.

Food first (always): At Windback, we like to start with food before we talk about supplements. Creatine is naturally found in animal foods, especially muscle meat and fish, so if you already eat these regularly you may be getting small amounts day to day. The most creatine-rich choices tend to be red meat (beef and lamb) and oily fish such as salmon and herring, followed by pork, poultry, and other fish like tuna and cod.

That said, the amounts used in many creatine studies are difficult to reach consistently through food alone. A practical “food-first” approach is to build meals around adequate protein and include creatine-containing foods a few times per week where that fits your preferences, budget, and goals. If you do not eat meat or fish (or you eat very little), you can still support your body’s natural creatine production by prioritising foods that provide the building blocks (amino acids) for creatine synthesis, such as eggs, dairy, legumes, pumpkin and sesame seeds, and nuts.

Why creatine is popular for strength and training

The strongest evidence for creatine is in physical performance, particularly where quick energy output matters. Creatine monohydrate is commonly used to support:

Strength and power during training blocks
Repeated high-intensity efforts (more quality work across sets)
Training consistency, which is a big part of long-term progress

In plain terms, creatine helps your muscles produce energy faster during hard efforts, so you can push training quality and repeatability. That matters because the real “secret” to results is not motivation, it’s accumulating enough high-quality resistance training over time.

After 40 and especially after 50, maintaining muscle becomes less forgiving. You can still build strength and muscle, but the margin for inconsistency is smaller. Creatine monohydrate is one of the most evidence-backed supplements to support strength gains and lean mass improvements when your training and protein intake are already in place.

Creatine and the brain: why longevity-focused people care

The brain uses a lot of energy. Creatine is stored in brain tissue and acts as part of the brain’s energy system, which is why it is being explored for cognitive performance in certain contexts, such as intense mental effort, reduced sleep, or low baseline creatine intake.

Creatine may be most noticeable for cognitive performance in situations like:

Lower dietary creatine intake (for example, vegetarians or people who eat very little animal protein)
High cognitive demand (busy seasons, heavy workloads, exams)
Sleep restriction (although it is not a substitute for sleep)

It’s important to keep expectations realistic. Creatine is not a replacement for sleep, nourishing food, movement, and stress regulation. It is best viewed as a supportive tool alongside the fundamentals.

Creatine for headaches and brain injuries: promising, but still emerging

Creatine is also being explored in clinical contexts, including recovery after traumatic brain injury and post-injury symptoms such as headaches and fatigue. Some early studies suggest potential benefit, but this area is still developing and findings are not definitive. If you have concussion symptoms, migraines, or persistent headaches, discuss personalised options with a qualified healthcare professional rather than self-treating.

How to take creatine

Which type is best? Creatine monohydrate is the most researched form and the standard used in most studies. It is typically the best value option and the one with the strongest evidence base.

Do you need a loading phase? For most people, no. A steady daily dose is a simple approach, and it can help avoid stomach upset that some people experience with large “loading” doses.

Does timing matter? Timing is not considered critical. Many people take it at a consistent time each day (often with a meal), simply because routine improves consistency.

Should you take it with food? Some people prefer taking creatine with food, and some evidence suggests co-ingestion with carbohydrates may improve uptake. Practically, the key factor is consistency.

What is a sensible creatine dose?

The most common daily dose used is 3 to 5 grams per day for most adults. Some people choose 5 to 10 grams per day depending on body size, training demands, and tolerance.

If you are new to creatine or have a sensitive stomach, start low (for example 3 grams daily) and increase gradually as tolerated. Staying well hydrated is also sensible, especially if you train hard or sweat heavily.

Expert perspective: why creatine matters for healthspan

Across performance science and functional medicine, creatine is often singled out as a rare supplement that is both well-studied and genuinely useful in real life. The reason is not hype. It supports cellular energy availability during high-demand moments, which is exactly where strength training, power, and training quality live.

Longevity-focused clinicians such as Dr Casey Means tend to frame creatine as an “energy nutrient” that can support midlife strength and resilience when the foundations are in place: protein, resistance training, sleep, and metabolic health. The emphasis is consistency over complexity, and creatine monohydrate is typically the form most people start with.

Performance physiologists such as Dr Andy Galpin commonly return to a simple point: if something helps you train better, recover more reliably, and stick to the plan, it can compound into meaningful long-term outcomes. Creatine is one of the most evidence-backed options for that, particularly for strength and repeated high-intensity efforts.

Keep it simple: creatine monohydrate is the most researched form.
Consistency wins: daily dosing is typically more important than timing.
Foundations first: creatine supports the work, it doesn’t replace it.

Note: This is general education, not personalised advice. If you have kidney disease, a history of kidney issues, are pregnant or breastfeeding, or take medicines that affect kidney function, get individual guidance before supplementing.

Is creatine safe?

Creatine monohydrate is widely considered safe for most healthy adults when used at standard doses. One common point of confusion is that creatine can increase blood creatinine on lab tests, which does not automatically indicate kidney damage. If you have kidney disease, a history of kidney issues, are pregnant or breastfeeding, or are taking medicines that affect kidney function, seek medical advice before using creatine.

Pairs well with creatine

If creatine is your “energy buffer” for training, these can be smart add-ons to support the bigger picture: protein targets, hydration, recovery, and staying mobile enough to keep training for decades.

The takeaway

If you care about healthy ageing, creatine deserves a serious look. Not because it’s trendy, but because it’s one of the few supplements with decades of research behind it. It supports the work that actually protects healthspan: strength training, power, recovery, and the capacity to keep showing up.

Think of it this way: the goal is not perfection, it’s staying capable. Adequate protein, progressive resistance training, sleep, and everyday movement do the heavy lifting. Creatine monohydrate is one of the simplest add-ons that can help those foundations deliver better results over time.
