Creatine vs Protein

• Protein supplies the amino acids your body uses to build and repair muscle. You need it every day, mostly from food.
• Creatine isn't a protein. It helps your muscles produce energy for short, hard efforts like lifting or sprinting, which can let you train a little harder [1].
• They do different jobs, so one doesn't replace the other, and they're fine to take together [1][2].

Creatine is a compound your body makes from three amino acids (arginine, glycine and methionine) and stores mostly in muscle. It also comes from food, mainly meat and fish [1].

In muscle, creatine is stored as phosphocreatine, which quickly regenerates the energy your muscles use in the first few seconds of an intense effort. Supplementing raises those stores, which is why the main benefits show up in repeated high-intensity work and strength training [1].

No. Even though it's made from amino acids, creatine isn't a protein and doesn't count toward your daily protein target. A 5g scoop of creatine adds nothing to your protein total, so you still need to hit your number from food or protein powder. Work out your target with the protein calculator.

Yes. There's no interaction to worry about, and mixing creatine into your protein shake is a simple way to remember it. Taking creatine with a meal or shake containing protein and carbohydrate may even help your muscles take it up [1].

Timing matters much less than taking it consistently every day, because the benefit comes from keeping your muscle stores topped up rather than from any single dose [1][2].

The most researched form is creatine monohydrate [1]. There are two common approaches:

• Steady: 3–5g a day. Muscle stores fill up over about three to four weeks [1].
• Loading: about 0.3g per kg of body weight a day (roughly 20g, split into four doses) for 5–7 days, then 3–5g a day. This fills stores faster but isn't necessary [1][2].

Both end up in the same place. Some people find a loading phase upsets their stomach, which is a good reason to just start at 3–5g.

• People doing strength or high-intensity training: this is where the evidence is strongest [1]. The Australian Institute of Sport rates creatine among the supplements with strong evidence for specific sporting situations [3].
• Vegetarians and vegans: without meat or fish, muscle creatine stores tend to be lower, so supplementing can raise them more [1].
• Older adults doing resistance training: research on creatine alongside strength training in older adults is promising [1][2].
• Not only men or bodybuilders: the research includes women, and the same dosing applies [2].

Creatine monohydrate is one of the most studied supplements. For healthy people, the research hasn't found it harms the kidneys or liver at recommended doses, including in longer-term studies [1][2]. It isn't a steroid [2].

Expect a small rise in body weight in the first weeks, mostly from extra water stored in muscle rather than fat [1][2]. If you have kidney disease, take regular medication, are pregnant or breastfeeding, or are under 18, check with your GP first. Athletes who are drug-tested should choose a product that's been batch-tested for banned substances [3].

Creatine can add a little to your training, but it won't make up for too little protein, too few calories or inconsistent training. Get your daily protein right first, spread it across your meals, then consider creatine as an extra. See our protein for muscle gain guide and how much protein per meal.
