Does Creatine Break a Fast?

Reviewed by the FastTrack team · Updated June 2026

Short answer: No

Plain creatine does not break a fast. Creatine monohydrate has no calories and does not raise insulin, so it will not interrupt fat loss, ketosis, or autophagy.

Why creatine is fast-safe

Creatine monohydrate is a calorie-free compound that the muscles use for energy production. On its own it does not provide dietary calories or meaningfully raise insulin, so a daily dose of plain creatine does not break a fast. This makes it popular with people who train fasted.

Avoid the loaded versions

Stick to plain creatine monohydrate powder mixed in water. Many pre-mixed or flavored creatine products, and creatine gummies, add sugar or carbohydrate that will break a fast. Read the label and choose an unflavored, single-ingredient powder.

How much is safe

The usual three to five gram daily dose of plain creatine in water is fine at any time during a fast.
