Tons of us already take creatine for strength and muscle mass, but as trainer Dan Go shared, it’s also a powerful fat-burning supplement. If you have fat-loss goals this year, creatine should be part of your routine, he says.

“It [creatine] supports fat loss by helping you build and retain muscle, which helps you maintain a healthy metabolism,” Go tweeted.

Go is a fitness coach who specializes in training busy professionals and entrepreneurs. Last week, he shared how he’s been experimenting with max doses of creatine, averaging about 15 grams a day—raking in a lot of creatine-related questions.

“Creatine is a natural substance found in your muscles and brain. It’s made of amino acids and acts as a quick energy booster for your workouts while also having a positive impact on your brain,” he said.

It’s been extensively studied, and shown to enhance athletic performance, helping increase strength and power output, as well as, improving sprint speed and recovery. Go says it also plays a key role in boosting muscle mass, especially when paired with resistance training.

Building muscle has a direct impact on your metabolism because muscle tissue requires more energy to maintain than fat tissue. This means that the more muscle you have, the higher your resting metabolic rate will be.

As a result, your body burns more calories at rest—even when you’re not actively working out—helping support fat loss.

For dosage, Go says to start with five grams per day. If you’re a larger individual, you may need between five and ten grams. However, if you experience stomach discomfort, try reducing the dose to two grams a day and increase as tolerated.

“Be patient—it takes a few weeks to see results,” Go says.
