What is creatine loading – and is it right for you?

Lauded as an essential midlife supplement for its relatively low cost, simple nutrient profile and ability to boost muscle mass and reduce menopause symptoms such as brain fog and sleepless nights, creatine is having its moment. As a wellness journalist I’m asked about it several times a week – whether in the gym, at dinner with friends or by people sliding into my DMs asking whether it’s really the wonder powder it’s made out to be.

There’s no doubt about the benefits. I’ve experienced the perks of taking the recommended daily amount of 3-5g first hand. Paired with regular weight training my once weedy arms have evolved into defined powerhouses and I can lift much heavier things than I used to.

However, though plenty of studies show that creatine is great for muscle and bone health and suggest promising results for improved cognition, there’s some debate online about how best to take it, particularly if you’re trying it for the first time. Some fitness experts recommend starting off with four to seven times the recommended serving size of creatine in order to see results faster – that’s a huge 20g serving daily. And the notion of taking a short-term mega-dose to help improve brain function is also gaining traction. One study suggests that taking 20g per day for a week can boost cognition and memory in older women aged 60+.

Taking larger amounts, particularly at the start of your supplementation journey is known as creatine loading. But is the trend an unnecessary fad or a stroke of genius for women wanting to quickly build strength and boost cognition?

How does a creatine loading phase work?

Rob Hobson, registered nutritionist and author of The Low Appetite Cookbook, £14.56, explains that this loading strategy has been used in sports nutrition for decades and is well-established for increasing muscle creatine stores more quickly.

“Part of the reason it’s suddenly trending is that social media loves the message: don’t wait a month. Get the benefits in a week,” he says.

The traditional loading protocol, says Hobson, involves taking a dose of approximately 20g of creatine per day for five to seven days. That’s a lot of creatine, so he recommends splitting that dose into four lots of 5g  throughout the day to avoid unwanted side effects, such as bloating (more on this below).

Taking a larger dose for a short time affects the speed at which muscles are saturated. When muscle creatine stores are flooded with the supplement, they reach 100 per cent capacity in the space of a week, boosting your cellular energy and making it easier to perform athletically and lift heavier. Human muscle creatine stores are usually only at about 60-80 per cent full so creatine loading forces saturation of the muscle tissues.

Is creatine loading backed by evidence?

Creatine monohydrate is a relatively inexpensive flavourless powder. Taking a dose of 20g daily wouldn’t be an impossible task if one simply mixed the powder with water, food or a smoothie. However personal trainers and experts in midlife fitness, like Lavina Mehta MBE, advise that supplementing creatine, whether in large or small amounts, is all about consistency and timing.

She says, “I’m generally a fan of creatine monohydrate because it’s one of the most researched supplements available, with evidence supporting its role in strength, muscle function and healthy ageing. Research shows that loading does work, but it doesn’t necessarily produce greater long-term benefits than taking a regular daily dose – it simply gets you there faster.”

Hobson echoes this, pointing out that if improved muscle size and definition is your goal, supplementing consistently with a lower dose of creatine is an effective, safe science-backed solution offering the same results as loading.

“Creatine is one of the most well-researched supplements available but the question is less about whether to load and more about whether you want the benefits sooner rather than later. Some evidence suggests taking it alongside a meal or after exercise may slightly enhance uptake, but the overall difference is likely to be small compared with simply taking it consistently every day.”

Creatine loading vs no loading

So why might you creatine load? Hobson explains that the protocol is commonly used by athletes to bulk up quickly, for example: “if someone has left it relatively late before a competition, race or a period of intensive training and wants to maximise muscle creatine stores as quickly as possible.”

However, loading won’t suddenly make you stronger overnight. Creatine doesn’t work in isolation, it supports your muscles during exercise so in order to feel stronger and grow muscle, you would have to lift weights and progressively challenge yourself with more weight while taking it.

So, if you’re loading before a Hyrox competition, for example, ensure that your training matches your loading protocol and that you’re also building recovery into your routine. Loading offers the best results alongside hydration, a balanced diet and rest days.

Are there any risks associated with loading?

The most common side effect of creatine loading is temporary weight gain. This is a normal effect and doesn’t mean the body is gaining fat, as nutritionist Emma Bardwell explains in her post above, it just means that muscle creatine stores are becoming saturated.

Mehta, author of The Feel Good Fix, £14.75, explains that, “this side effect is temporary because creatine draws water into the muscle cells. Some women notice they feel slightly puffier or see the scale increase by a pound or two in the first week. This isn’t body fat, but it can be unsettling if you’re not expecting it.”

Some people may also experience digestive discomfort, bloating or stomach upset when taking larger doses. Personally, this is why I stick to a 5g daily limit.

“This is one reason why splitting the daily loading dose into smaller servings throughout the day tends to be the best approach,” advises Hobson. “For healthy individuals, creatine has an excellent safety profile, but I wouldn’t recommend it to someone with pre-existing kidney disease,” he adds.

Is it a good idea for women to load? Or just gym bros?

Midlife is a particularly beneficial time to start supplementing with creatine because hormonal changes can contribute to losses in muscle mass and bone density but the most important thing to consider when taking any supplement is the uniqueness of your own health profile. Some people lift heavier weights, compete in athletic competitions and can tolerate larger doses of a supplement, others might be at the start of a relationship with the gym so it’s worth considering whether loading is right for you before jumping in.

“One of the biggest challenges during perimenopause and menopause is the accelerated loss of muscle mass and strength that occurs as oestrogen declines,”  says Mehta. “Muscle is one of the best predictors of healthy ageing. It supports metabolism, balance, mobility, independence and even bone health. Emerging research suggests creatine may help support lean muscle mass and strength in postmenopausal women, especially when combined with resistance training.”

However, Hobson points out that, “there is currently not enough research to recommend routinely taking higher doses for cognitive or menopause-related benefits. At present, 3-5g daily remains the evidence-based recommendation for most women.”

He also stresses that women do not need a special ‘female creatine’. “Many products marketed specifically at women are simply creatine monohydrate in more expensive packaging. The creatine molecule is exactly the same so save your money and choose a reputable creatine monohydrate product instead.”

What to know when creatine loading, at a glance

• Split loading doses throughout the day to minimise digestive discomfort.
• Take consistently, with food and plenty of water, including on rest days.
• Don’t expect dramatic overnight changes. Even when muscle stores become saturated quickly, noticeable changes in strength and performance still depend on consistent training.
• Combine with strength training and adequate protein intake.
• Look for third-party tested, pure creatine monohydrate and avoid added sugars and artificial dyes.
• Don’t panic if the scales go up slightly. That’s water being stored inside muscle tissue, not fat gain.

Remember that supplements supplement, they don’t replace the fundamentals. While creatine is considered safe for healthy people, talk to your GP first if you have any kidney concerns, are on medication, or have pre-existing health conditions.

Creatine loading: our verdict

Unless you’re training hard within a limited time window, have a specific physical goal to meet or are conducting your own research on the effects of loading, there’s no pressure to try the trend because the long-term benefits are exactly the same as the short term.

As Hobson points out, “for most women, particularly those taking creatine to support strength training, muscle retention during midlife or healthy ageing, there is usually no urgency. In these situations, taking 3-5g daily is often the simplest way to do it.”

It’s also worth noting that while it’s satisfying to see results more quickly, considering what your body can tolerate and building a sustainable routine that works for you is paramount. As Mehta says, “while creatine isn’t a miracle cure, it may be one of the few supplements that genuinely supports the things many women care about most: staying strong, maintaining muscle, protecting function and continuing to do the activities we love for years to come.”
