What Does Creatine Do? Benefits, How It Works & How to Take It

Let's take a closer look at what creatine does, how it works and how you can make it part of your daily routine.

What is creatine?

Creatine is a naturally occurring compound found in the human body, primarily stored in skeletal muscle.

Your body can produce creatine itself, and you can also obtain small amounts through foods such as meat and fish. Creatine supplements provide an additional source, with creatine monohydrate being the most commonly used form.

When you supplement with creatine, the amount of creatine stored in your muscles can increase. European scientific literature reports increases in total muscle creatine of around 15–20% on average, although individual responses vary.

What does creatine do in your body?

To understand creatine, it helps to understand ATP.

ATP (adenosine triphosphate) is essentially an immediate source of energy for your cells. During intense exercise, your muscles use ATP very quickly.

Your muscles also store creatine in the form of phosphocreatine. This system helps replenish ATP when energy demand suddenly becomes very high.

That's particularly important during short and explosive efforts.

Think about:

• Heavy strength-training sets
• Sprinting
• Repeated jumps
• Short high-intensity intervals
• Explosive efforts during team sports

As an intense effort continues, other energy systems increasingly take over. That's one reason why creatine is particularly associated with short-duration, high-intensity exercise rather than simply being an “energy supplement” for every type of activity.

What are the benefits of creatine?

The best-established benefit of creatine is related to physical performance.

The authorised EU health claim states:

Creatine increases physical performance in successive bursts of short-term, high-intensity exercise.

The beneficial effect is obtained with a daily intake of 3 g of creatine.

This makes creatine particularly interesting for people whose training involves repeated explosive efforts.

What does creatine do for strength training?

Creatine is extremely popular among people who lift weights because resistance training frequently involves exactly the type of activity where the phosphocreatine system matters.

Imagine performing a heavy set of squats.

For a short period, your muscles need to produce a large amount of force. You rest, recover and then repeat the effort.

Scientific assessments of creatine have found improvements across different protocols involving short-duration maximal exercise, including resistance exercise, repeated jumping and sprinting.

That's why creatine isn't just something for bodybuilders. It can fit into the routine of many people performing short, intense and repeated efforts.

Does creatine build muscle?

This question needs a little nuance.

Creatine isn't protein, and taking a scoop doesn't directly “build muscle” on its own.

Its established role is in supporting performance during successive bursts of short-term, high-intensity exercise. That makes it useful alongside a well-designed resistance-training programme.

Training, sufficient protein, nutrition, recovery and consistency still matter.

In other words: creatine complements your training — it doesn't replace it.

Is creatine useful for sprinting?

Creatine can be particularly relevant for sports involving repeated short, explosive efforts.

European scientific reviews have examined creatine in activities including sprinting, repeated jumping, swimming, rowing and resistance exercise. The effects are particularly relevant where high-power efforts are repeated with relatively short recovery periods.

That means creatine isn't only for someone standing beside a squat rack.

Football players, sprinters, CrossFit athletes and other athletes performing repeated high-intensity efforts may also be interested in creatine supplementation.

How much creatine should you take per day?

A common approach is to consume creatine consistently every day.

The authorised EU performance claim is based on a daily intake of 3 g of creatine. Scientific literature has also shown that approximately 3 g per day over a longer period can gradually increase muscle creatine stores.

Bites Creatine + Dextrose provides 4 g of creatine monohydrate per serving.

That makes the routine simple:

One scoop. 500 ml water. Every day.

Do you need a creatine loading phase?

Not necessarily.

You may have heard of a “loading phase”, where a considerably larger amount of creatine is consumed for several days before switching to a lower daily intake.

Loading can increase muscle creatine stores more rapidly, but it isn't the only way to use creatine. Scientific literature also shows that taking approximately 3 g per day over around a month can gradually increase muscle creatine stores.

For many people, keeping things simple and consistent is easier.

Should you take creatine before or after your workout?

You don't need to make your creatine routine unnecessarily complicated.

Rather than obsessing over a tiny timing window, make your daily serving part of a routine you can consistently maintain.

At Bites, we like it after training.

Finish your workout, add one scoop to 500 ml of cold water, shake and drink.

On rest days, simply take it at a convenient moment during the day.

Should you take creatine on rest days?

Creatine supplementation is about maintaining increased creatine stores rather than getting a stimulant-like effect immediately after drinking it.

That's why a consistent daily routine makes sense — including days when you're not training.

An easy trick is to connect your creatine to something you already do every day.

For example:

Training day: after your workout
Rest day: with lunch or another regular daily habit

The easier your routine is, the easier it is to stay consistent.

Does creatine cause water retention?

Creatine can cause an increase in body water.

As creatine is retained in muscle, water retention can occur alongside it. Research reviewed by European scientific bodies has reported increases in body mass during high-dose creatine loading protocols, with water retention considered an important contributor to that initial change.

So seeing the number on the scale increase after starting creatine does not automatically mean you've gained body fat.

What is creatine monohydrate?

Creatine monohydrate is the classic and extensively studied form of creatine.

You may see many different types of creatine marketed online, but a complicated name doesn't automatically make a product better.

Bites uses creatine monohydrate and focuses on something very simple:

Making your daily creatine routine enjoyable enough to stick with.

Why does Bites combine creatine with dextrose?

Bites Creatine combines creatine monohydrate with a small amount of dextrose and a refreshing lemon flavour.

Dextrose is a simple carbohydrate.

You may see claims online that adding carbohydrates automatically makes creatine “work better”. Be careful with those claims. In fact, the EU Register lists proposed claims that creatine combined with carbohydrate increases creatine retention or improves its delivery to muscle as non-authorised health claims.

So our approach is simpler:

We wanted to create a creatine drink that is easy and enjoyable to make part of your routine.

Does creatine taste good?

Pure creatine monohydrate isn't exactly famous for being an exciting drink.

And that's something we wanted to change.

Bites Creatine + Dextrose has a refreshing lemon flavour and is designed to be mixed with 500 ml of cold water.

Instead of thinking:

“I still need to take my creatine.”

We want you to think:

“Time for my Bites.”

Because the best routine is one you can actually stick to.

How to take Bites Creatine

It's simple:

1 scoop
+ 500 ml cold water

Shake or stir well and enjoy.

For us, creatine doesn't need to be complicated.

Frequently Asked Questions About Creatine

What does creatine do?

Creatine helps support the rapid energy system used during short, intense exercise. Creatine increases physical performance in successive bursts of short-term, high-intensity exercise when consumed at the amount specified for the authorised EU health claim.

How does creatine work?

Creatine stored as phosphocreatine plays a role in rapidly regenerating ATP, which muscles use for energy. This system becomes particularly important when energy demand rises rapidly during intense exercise.

How much creatine should I take?

The recognised EU performance benefit is obtained with a daily intake of 3 g creatine. Follow the serving instructions of the specific product you're using.

Is creatine only for bodybuilders?

No. Creatine is relevant to repeated short, high-intensity exercise, which can occur in strength training, sprinting and various other sports.

Do I need to take creatine every day?

Creatine is generally used consistently to build and maintain muscle creatine stores rather than as an immediate stimulant. A simple daily routine can therefore make supplementation easier to maintain.

Is creatine a pre-workout?

Creatine and stimulant-based pre-workouts are different. Creatine's main purpose isn't to give you an immediate feeling of energy or alertness. Its recognised benefit relates to physical performance during successive bursts of short-term, high-intensity exercise.

Creatine doesn't have to be complicated

Creatine has been extensively studied, but your daily routine doesn't need to feel scientific.

Train consistently. Eat well. Recover. And keep your creatine routine simple.

That's why we created Bites Creatine + Dextrose with 4 g creatine monohydrate per serving and a refreshing lemon flavour.

One scoop. 500 ml water. Every day.

Creatine that actually tastes good. 🍋
