# Creatine: what it is, what it does and how people take it

Creatine is one of the most researched supplements in sport. It is also surrounded by myths. Here is a plain summary of **creatine benefits**, how people usually take it, and when to be cautious.

## What creatine is

Creatine is a compound your body makes and that you also get from foods such as meat and fish. Muscles use it to regenerate energy quickly during short, intense efforts, like a heavy set or a sprint. Supplementing raises the amount stored in muscle.

## Creatine benefits

- **Performance in short, intense efforts.** Research consistently supports small improvements in repeated high-intensity work.
- **Strength and muscle with training.** Combined with resistance training, creatine is associated with greater gains in strength and lean mass for many people.
- **Ongoing research** looks at other areas, such as ageing muscle and brain health. Those results are promising but less settled.

Creatine does not replace training. It helps you do a little more of the work that causes progress.

## How people take it

- **Form:** creatine monohydrate is the most studied form.
- **Daily dose:** a common approach is around 3 to 5 grams a day.
- **Loading phase:** some people take a higher dose for a few days to fill muscle stores faster; it is optional.
- **Timing:** taking it consistently matters more than the exact time of day.

## Common myths about creatine

- **“It is a steroid.”** It is not. It is a compound your body already makes and that you also get from food.
- **“It is only for bodybuilders.”** People in many sports use it, because its benefits relate to short, intense efforts of all kinds.
- **“More is better.”** Once your muscle stores are full, taking extra does not add benefit, and large single doses are more likely to upset your stomach.
- **“The weight gain is fat.”** The early increase is usually water held in muscle, as explained below.

## Side effects and cautions

In healthy adults at common doses, creatine is generally considered safe. The most frequent effect is a small gain in body weight from water held in muscle. Some people notice stomach discomfort, especially with large single doses.

Check with a doctor first if you have kidney disease or another medical condition, take regular medication, are pregnant or breastfeeding, or are under 18. Choose products that are tested by an independent third party, as supplements are not regulated like medicines.

## Frequently asked questions

### Does creatine damage the kidneys?

Research in healthy people has not shown harm at common doses. People with existing kidney problems should not take it without medical advice.

### Do I need to cycle creatine?

Many people take it continuously at a steady daily dose. There is no widely accepted need to cycle it.

### Are creatine benefits the same for everyone?

No. People respond differently, and some notice little change at all. Your own training record is a better guide than anyone else’s results.
