Amazon UK Site: Amfit Creatine Monohydrate Powder

If you’re anything like me, you have a lot on your mind. There are important things your partner mentions – dates, details, feelings – which, despite your best intentions, sometimes just don't stick. The mental RAM is full. And then it comes: "Why don't you ever remember?" or the one that truly stings, "You obviously don't care about me because you forget all the time."

It’s a frustrating cycle. You do care, immensely. But the brain’s filing system seems to have gone on strike. This very cycle led me on a personal quest. I wanted to find something to sharpen the edges, improve my recall, and maybe, just maybe, lead to fewer of those painful conversations.

This search led me to a supplement overwhelmingly associated with gyms and muscle growth, but which is now gaining serious scientific attention for its role inside our heads: Creatine Monohydrate.

For the past month, I have been taking a simple, unflavoured creatine powder every morning. Specifically, Creatine Monohydrate Powder, which is pure creatine monohydrate with no other fillers. So, has my memory miraculously improved? I can’t remember (that’s a joke). In all seriousness, something has shifted. Perhaps I am genuinely improving, or perhaps it's the placebo effect that my partner suspects. Either way, there has been a noticeable drop in the "you never listen" chorus.

My personal conclusion? If the risk of harm is low, which extensive research on low dosages suggests it is, and there is a potential benefit, why not try it?

But as a reviewer who values evidence over anecdotes, I needed to know why it might be working. Is there real science here? I dove into the clinical research, and what I found was both surprising and compelling. Let's break down the science behind creatine for memory and, more importantly, how it fits into the bigger picture of eating for a sharper mind.

What is Creatine, and What Does It Do To Your Brain?

Your brain is the most energy-hungry organ in your body, demanding around 20% of your total calories and oxygen, even when you're just resting. Every thought, every memory you form or retrieve, is an energy-intensive process.

This is where creatine steps in. It plays a fundamental role in the brain's energy production system. Think of it as a rapid-recharge power bank for your cells. Creatine helps to quickly regenerate your brain's primary energy molecule, adenosine triphosphate (ATP). When you perform a mentally demanding task—like concentrating in a long meeting or trying to recall a key detail from a conversation—your brain burns through ATP at a high rate.

By supplementing with creatine, you can increase the stores of creatine within the brain, enhancing its ability to produce ATP on demand and fuel these intensive mental processes.

The Scientific Evidence: Can a Scoop of Powder Boost Recall?

This isn't just a theory; it's backed by a growing body of high-quality research.

Multiple systematic reviews and meta-analyses—the gold standard of evidence which pools the results of many individual studies—have found that creatine supplementation can significantly improve memory. A comprehensive meta-analysis from 2024 concluded that creatine has a

significant, positive effect on memory performance. The researchers even graded the certainty of this evidence for memory as "moderate," which in scientific terms, shows a respectable level of confidence in the finding.

Another major meta-analysis from 2022 came to a similar conclusion, finding that creatine supplementation enhanced memory and noting a particularly strong effect in older adults aged 66-76 years. This suggests creatine might be especially helpful in counteracting the natural, age-related decline in our brain's energy efficiency.

It's important to be specific, however. While the evidence for memory is moderately strong, the 2024 analysis did not find a significant impact on other areas like overall cognitive function or executive function (things like planning and decision-making). This specificity actually strengthens the argument—creatine seems to be most effective at supporting the high-energy tasks of memory encoding and retrieval.

Is Creatine Safe?

For any supplement, safety is the number one concern. The good news is that creatine monohydrate is one of the most studied supplements on the market and is generally considered safe for long-term use (up to five years) in healthy individuals at the recommended dose of 3-5 grams per day.

The most common side effects are mild and may include some gastrointestinal upset or bloating, especially if you start with a higher "loading" dose. A more well-known side effect is a slight increase in body weight, which is simply due to water being drawn into muscle cells, not fat gain.

A common question revolves around kidney health. Numerous studies in healthy people have found no evidence that creatine harms the kidneys. It does cause a harmless increase in a blood marker called creatinine, which can sometimes be misinterpreted by standard lab tests as a sign of kidney problems. This is a known phenomenon and one for doctors to be aware of. However, to be cautious, notes from research individuals with any pre-existing kidney disease should avoid creatine unless cleared by a specialist.

The "Food First" Principle: Why Supplements Are Only Part of the Story

While the evidence for creatine is promising, no single supplement can ever replace the profound, synergistic power of whole foods. The most robust scientific evidence for protecting your brain for the long haul comes from studying comprehensive dietary patterns.

When you eat a blueberry, you're not just getting one antioxidant; you're getting a complex matrix of vitamins, fibre, and phytonutrients that work together in ways an isolated pill cannot replicate. This is why any conversation about cognitive enhancement must start with your plate.

Two dietary patterns stand out in the research for their incredible neuroprotective effects: the Mediterranean Diet and the MIND Diet.

The Superstars of Brain Food

Adopting a diet like the Mediterranean or MIND diet is the most impactful nutritional strategy you can employ for long-term brain health. These diets are built on a foundation of specific foods packed with the nutrients our brains crave.

Oily Fish: Your brain is about 60% fat, and the omega-3 fatty acid DHA is a primary structural component of your brain cells. Getting plenty of it from sources like salmon, mackerel, and sardines is crucial for the health of your neurons, which are essential for learning and memory. Some research even suggests regular fish consumption is linked to lower levels of beta-amyloid, the protein that forms harmful plaques in Alzheimer's disease.
Berries: The deep colours of blueberries, strawberries, and blackberries come from powerful antioxidants called flavonoids. These compounds can cross the blood-brain barrier, where they are thought to help reduce inflammation and improve communication between brain cells.
Leafy Green Vegetables: Spinach, kale, and other greens are packed with brain-protective nutrients like vitamin K, folate, and beta-carotene. Vitamin K, in particular, is vital for producing sphingolipids, a special type of fat that is densely packed into our brain cell membranes.
Nuts and Seeds: Walnuts, almonds and flaxseeds are great plant-based sources of omega-3s and antioxidant vitamin E, which are both linked to better cognitive function.
Eggs: The humble egg yolk is one of the best dietary sources of choline, an essential nutrient your body uses to make acetylcholine—a neurotransmitter that is vital for memory and mood. The evidence here is compelling: one recent study that followed older adults and even conducted autopsies found that those who ate more eggs had significantly fewer of the hallmark amyloid plaques and tangles of Alzheimer's disease in their brain tissue. This provides a powerful link between a specific food, its key nutrient, and a reduction in the physical cause of dementia.
Whole Grains, Olive Oil, and Turmeric: Foods like oats and brown rice provide a steady supply of glucose, the brain's main fuel. Extra virgin olive oil, a cornerstone of the Mediterranean diet, is rich in antioxidants that fight inflammation. Turmeric contains curcumin, a compound that may help clear amyloid plaques and boost Brain-Derived Neurotrophic Factor (BDNF), a protein that supports the growth of new neurons.

A Tiered Plan for a Sharper Mind

So, where do you start? Based on the weight of scientific evidence, the best approach is a tiered one.

Tier 1 (Highest Priority): The Lifestyle Foundation

This is the non-negotiable bedrock of brain health, supported by the strongest evidence.

Diet: Adopt a whole-food dietary pattern like the MIND or Mediterranean diet. This is the single most powerful nutritional strategy you can use.
Exercise: Aim for at least 150 minutes of moderate physical activity per week, like brisk walking or cycling.
Sleep: Prioritise 7-8 hours of quality sleep per night. This is when your brain consolidates memories and clears out metabolic waste.
Stay Engaged: Challenge your brain by learning new things and maintaining strong social connections.

Tier 2 (Targeted Support): Consider Creatine

This is for when the foundation is solid.

Creatine Monohydrate: For a healthy adult seeking specific support for memory function, supplementing with 3-5 grams of creatine monohydrate daily can be a beneficial, evidence-supported strategy. Always speak to your doctor first to rule out any health issues, especially pre-existing kidney conditions.

Tier 3 (Use with Caution): Other Supplements

This tier includes supplements that are popular but have weaker evidence and higher risks.

Herbal Supplements (Ginkgo Biloba, etc.): In contrast to creatine's focused data, the evidence for many herbal supplements is inconsistent and low-quality. More importantly, they carry a significant risk of side effects and serious interactions with common medications (like blood thinners and antidepressants). For most people, the uncertain benefits of these herbs are outweighed by the potential risks.

Final Thoughts

My month-long trial with creatine has been positive. Fewer "you forgot" moments have certainly improved the harmony at home. But this journey has reinforced a more important truth: preserving our precious memory isn't about finding a single magic pill. It's the result of a sustained, holistic commitment to a brain-healthy lifestyle.

Start with your fork. Fill your plate with the vibrant, nutrient-dense foods that build a resilient brain. Move your body, prioritise your sleep, and keep your mind active. Once that foundation is firmly in place, a targeted, evidence-backed supplement like creatine monohydrate can be a sensible and effective tool to add to your cognitive toolkit. It’s a small step that, backed by science, might just help you remember the big things—and the little things—that truly matter.
