Are you worried about creatine weight gain? Fear not -  the short answer is that it's mostly water weight. But stick around, in this article we'll debunk the myths and dive into all things creatine, helping you navigate those gains without sinking in a pool of misconceptions.

What is Creatine Weight Gain?

To understand creatine weight gain, we first need to understand what creatine is and how it works. Creatine is a naturally occurring compound found in small amounts in certain foods like red meat and fish. It's also produced by our bodies and stored in our muscles, where it's used to provide energy during high-intensity activities, like lifting weights or sprinting.


When you supplement with creatine, your body's stores of creatine phosphate increase. This leads to a rise in the production of adenosine triphosphate (ATP), which is the primary energy source for your muscles during short bursts of intense activity. With more ATP available, your muscles can work harder and longer, which can result in improved strength, power, and muscle growth.


Now, let's get back to creatine weight gain. As mentioned earlier, creatine causes water retention, making your muscles appear larger and fuller. This increase in water weight is often mistaken for an increase in fat mass, leading to the misconception that creatine makes you fat.

Does Creatine Make You Gain Weight?

When it comes to creatine weight gain, there are plenty of misconceptions floating around. Many people believe that creatine causes weight gain, but this is only partially true. Creatine can indeed lead to an increase in body weight, but it's not necessarily due to an increase in fat mass. Instead, the weight gain is mostly attributed to water retention, as creatine pulls water into your muscle cells, making them appear larger and fuller. This effect is temporary, and once you stop taking creatine, the water weight will decrease.

Does Creatine Make You Fat?

The short answer is no, creatine does not make you fat. As previously mentioned, creatine weight gain is primarily due to water retention, not an increase in fat mass. In fact, creatine supplementation can help you build lean muscle mass, which can increase your metabolism and help you burn more calories throughout the day.


However, it's essential to maintain a balanced diet and exercise routine while taking creatine. If you consume too many calories or don't exercise enough, you may gain fat, regardless of whether or not you're supplementing with creatine.

How Does Creatine Work?

Creatine works by increasing your body's creatine phosphate stores, which in turn boosts the production of ATP. This extra ATP allows your muscles to work harder and longer during high-intensity activities, leading to improved performance and muscle growth.


Another way creatine works is by promoting protein synthesis, which is the process by which your body builds new muscle tissue. Research has shown that creatine supplementation can increase the rate of protein synthesis, helping your muscles grow and repair more quickly after exercise.

How Can You Minimize Water Retention From Creatine?

Although water retention is a natural side effect of creatine supplementation, there are ways to minimize its impact on your weight and appearance:


  • Stay hydrated: Drinking enough water can help regulate the balance of fluids in your body and reduce water retention.
  • Choose the right type of creatine: There are several different forms of creatine available, and some may cause less water retention than others. Micronized creatine monohydrate, for example, is more easily absorbed by the body, which could result in less water retention.
  • Cycle your creatine intake: Some people find that cycling their creatine supplementation – taking it for a few weeks, followed by a break – helps to minimize water retention.

Creatine for Gaining Muscle Weight

If your goal is to gain muscle weight, creatine can be a valuable addition to your supplement regimen. As we've discussed, creatine can help increase your strength, power, and muscle growth by providing your muscles with the extra energy they need during high-intensity activities. This can lead to more effective workouts and, ultimately, greater gains in muscle mass.

To maximize the benefits of creatine for muscle weight gain, consider the following tips:

  • Follow the recommended dosage: The typical recommended dosage for creatine is 3-5 grams per day. However, some individuals may choose to perform a "loading phase" by taking 20 grams per day for the first 5-7 days to saturate their muscles with creatine quickly. After the loading phase, they switch to a maintenance dose of 3-5 grams per day.
  • Combine creatine with carbohydrates: Some research suggests that combining creatine with carbohydrates may increase its uptake into your muscles. Consuming a high-carb snack or beverage alongside your creatine supplement could help maximize its effectiveness.
  • Time your creatine intake: While there's no consensus on the best time to take creatine, many people prefer to take it before or after their workouts. This can help ensure that your muscles have adequate creatine stores during your workout, leading to improved performance and muscle growth.

What to Do If You Gain Weight on Creatine

If you notice weight gain while supplementing with creatine, don't panic. Remember that this weight gain is likely due to water retention, not an increase in fat mass. Here are a few things you can do if you're concerned about creatine weight gain:

  • Track your body composition: Instead of focusing solely on your weight, monitor your body composition (the ratio of fat mass to lean mass). This can help you determine if the weight gain is due to water retention or an increase in fat mass.
  • Adjust your diet and exercise routine: If you're gaining fat, evaluate your diet and exercise habits. Make sure you're consuming an appropriate number of calories and getting enough exercise to maintain a healthy body composition.
  • Consider cycling creatine intake: As mentioned earlier, some people find that cycling their creatine supplementation helps minimize water retention. You might try taking creatine for a few weeks, followed by a break, to see if this approach works for you.

How to Prevent Creatine Weight Gain

While it's not always possible to completely prevent creatine weight gain, there are steps you can take to minimize its impact:

  • Stay hydrated: Staying hydrated can help regulate fluid balance in your body, potentially reducing water retention.
  • Choose the right type of creatine: Opt for a form of creatine that is less likely to cause water retention, such as micronized creatine monohydrate.
  • Monitor your calorie intake: Although creatine doesn't directly cause fat gain, consuming too many calories can. Be mindful of your calorie intake to avoid unwanted fat gain while supplementing with creatine.

FAQs about creatine weight gain

Does creatine weight gain go away?

Yes, creatine weight gain, which is primarily due to water retention, typically goes away once you stop taking creatine. Your body will gradually return to its normal fluid balance, and the extra water weight will be shed.

Should I take creatine if I'm trying to lose weight?

Creatine can be beneficial even if you're trying to lose weight, as it helps build lean muscle mass, which can increase your metabolism. Just ensure you maintain a healthy diet and exercise routine to avoid unwanted fat gain.

What happens when you stop taking creatine?

When you stop taking creatine, your body's creatine stores will gradually deplete, and the extra water weight will likely decrease. However, the strength and muscle gains achieved during creatine supplementation can be maintained with a consistent workout routine and proper nutrition.

Does creatine increase muscle size?

Creatine can increase muscle size in two ways: by causing temporary water retention, making muscles appear fuller, and by helping you build lean muscle mass through improved strength, power, and muscle growth during high-intensity activities.
