Does Creatine Make You Gain Weight? Here's What Actually Happens

If you've been thinking about taking creatine but keep hearing it "makes you gain weight", you're not alone. It's one of the biggest myths surrounding one of the world's most researched sports supplements.

Here's the good news: while creatine can cause a small increase in body weight, that doesn't mean you're gaining fat. In fact, for many women, it's a sign the supplement is doing exactly what it's supposed to do.

So, what actually happens when you start taking creatine, and should you be worried about the scales?

Does creatine make you gain weight?

Short answer: Yes, you might notice a small increase in body weight during the first few weeks of taking creatine, but it's almost entirely due to extra water being stored inside your muscles, not an increase in body fat. Don't stress about it.

For most people, any weight gain is temporary and modest. Over time, creatine can help support greater strength, improved training performance, and increased lean muscle mass when combined with resistance training.

What is creatine and what does it do?

Creatine is a naturally occurring compound found in your muscles that helps produce energy during short bursts of high-intensity exercise, like lifting weights, sprinting or HIIT workouts.

Your body makes creatine on its own, and you also get small amounts from foods like red meat and seafood. Taking a creatine supplement increases your muscles' creatine stores, helping you produce energy more efficiently during intense exercise.

This means you may be able to:

• Lift heavier weights

• Complete more reps

• Recover more effectively between sets

• Improve high-intensity exercise performance

• Support long-term gains in strength and lean muscle

Creatine monohydrate is the most researched form of creatine, with decades of evidence supporting its safety and effectiveness for healthy adults, including women.

Why does creatine make the scales go up?

When you start taking creatine, your muscles store more phosphocreatine. Research explains that along with that stored creatine comes extra water inside your muscle cells.

This is known as intracellular water retention, meaning the water is stored inside the muscle rather than under your skin or as body fat.

That's why some people notice a small increase in body weight shortly after starting creatine. Research suggests this is typically around 0.5-2 kg, particularly if you begin with a loading phase (around 20 g per day for 5-7 days).

Research suggests that if you skip that loading phase and simply take 3-5 g daily, your muscles will still become saturated over time, but the increase in water weight is often more gradual.

Does creatine make you gain fat?

No, creatine itself does not cause fat gain. It contains virtually no calories and doesn't increase body fat.

The only way to gain body fat is by consistently consuming more calories than your body burns.

If you've got a consistent strength-training routine and balanced nutrition, then creatine may help support your body composition goals by allowing you to train harder, recover better, and build or maintain lean muscle. Weight gain shouldn't be a concern here.

And if your goal is fat loss, it's worth remembering that the number on the scales doesn't always tell the whole story. A small increase in muscle water doesn't mean you've stopped making progress.

Does everyone gain weight on creatine?

Not necessarily. Some people notice the scales increase within the first couple of weeks, while others experience little or no change.

How much your weight changes can depend on several factors, including:

• Whether you use a loading phase

• Your muscle mass

• Your training routine

• Your usual diet

• How much creatine your muscles naturally store before supplementation

Everyone responds a little differently, so don't be surprised if your experience doesn't match someone else's.

Does creatine cause bloating?

Some people report feeling "bloated" when they first start taking creatine, but this is often misunderstood.

The extra water is primarily stored inside your muscle cells, not beneath your skin or around your stomach. Rather than making you look soft or puffy, many people actually notice their muscles appear slightly fuller.

If you're concerned about bloating, taking 3-5 g of creatine monohydrate per day instead of using a loading phase may help minimise temporary water retention.

Should women take creatine if they're trying to lose weight?

Absolutely! If you're working towards fat loss, seeing the scales increase can feel frustrating, but it's important to understand what's actually changing.

A small increase in water stored inside your muscles isn't the same as gaining body fat. Instead of relying on the scales alone, try tracking your progress using a combination of:

• Strength improvements

• Progress photos

• Body measurements

• How your clothes fit

• Energy and performance during workouts

Creatine can be a valuable addition to a fat-loss journey because it helps support strength, lean muscle, performance and recovery while you're in a calorie deficit.

How to take creatine

For most women, 3-5 g of creatine monohydrate per day is all you need.

Here's how to get the most out of it:

• Dosage: 3-5 g daily

• Type: Creatine monohydrate is the most researched, effective and affordable form (we definitely recommend that over gummies)

• Timing: Any time of day is fine as consistency matters more than timing

• Loading phase: Totally optional. It saturates your muscles faster but isn't necessary to experience the benefits

• Hydration: Drink enough water to support your body's normal hydration needs

Unlike some supplements, you don't need to cycle creatine on and off. Taking it consistently each day helps maintain your muscle creatine stores.

Level up with creatine

Yes, creatine can cause the number on the scales to increase slightly, but that doesn't mean you're gaining body fat.

The temporary increase in weight is largely due to extra water being stored inside your muscles, which supports energy production during exercise and helps you get more out of your workouts.

If your goal is to get stronger, improve your performance, support muscle recovery or build lean muscle, creatine is one of the most effective and well-researched supplements available. And while the scales might move a little at first, the long-term benefits can be well worth it.
