Studies show that creatine intake can increase muscle growth and increase energy levels, especially when taken with an effective resistance training program [1].

The effects on the body's muscles are undisputed, but I often get asked how much water I need to drink with creatine intake.

There are rumors that it could cause dehydration and have adverse effects on body muscles, such as muscle cramps. We've gone through hundreds of relevant pieces of information and in-depth research to put this claim to the test.

Let’s talk about how much water your body needs for proper hydration.

Quick Summary

  • Drink 500 ml of water for every 5 grams of creatine you take for better muscle protein synthesis.
  • Take at least 5 liters of water each day while taking creatine to avoid dehydration.
  • Headache is an indication you should take more water after taking your creatine supplement.
  • Increased thirst after taking creatine supplements is an indicator you should take more water.

How Much Water Should You Take With Creatine?

You should drink 300-500ml of water on top of your regular water intake if you drink with creatine (3-5g).

During the day your water intake should be at least 4 to 5 liters while taking creatine to avoid possible dehydration. If you feel some ingestion issues while consuming creatine, mix it with hot water or warm tea.

Do You Need To Drink More Water When Taking Creatine?

Do You Need To Drink More Water When Taking Creatine

You don’t necessarily need to typically drink more water when taking creatine.

If you’re doing a lot of fitness, then you will be drinking more water to ensure proper hydration. You have to replace the water you lose from the sweating created by your fitness training.

If you exercise intensely, you need to drink enough water to account for the sweat loss you experienced. If you live in a hot climate, you may also need more due to sweating throughout the day.

You should be mindful of your body and drink more water daily when you notice dehydration side effects. Some of the side effects of dehydration are:

  • Dry mouth
  • Headache
  • Increased thirsty
  • Tiredness
  • Dry Skin

Some people think that using creatine supplements causes dehydration because it causes water to go into the muscle cells.

I couldn’t find any research to support this theory—quite the opposite. I found research that suggests that it can help with hydration [2].

How Do You Mix Creatine With Water?

How Do You Mix Creatine With Water

You mix 3-5 grams of creatine monohydrate or one teaspoon with 8 oz of water until the powder is dissolved.

Here are some other things you should consider:

  • Use creatine monohydrate in micronized form as it’s smaller than normal creatine. It will mix better so you won’t have clumps in your drink.
  • Use warm water to improve the dissolving process. Creatine dissolves more slowly in cold water or liquids. However, it doesn’t make it any less effective.
  • It’s best to take your creatine freshly mixed; it might be tempting to pre-mix it, but it’s a terrible idea. Creatine supplement starts to degrade the moment it’s in contact with water, lessening its body weight gain effects.

Which Creatine Is Best For Mixing?


The micronized creatine monohydrate supplement is the best for mixing. Its particles are approximately 20 times smaller than the regular creatine powder particles, making it easier to dissolve in water without lessening its weight gain effects.

Creatine monohydrate is also the most researched version, so you will still get the full benefits of drinking the micronized form.

How Should I Take Creatine To See Results?

To see the results of taking creatine powder, you should do a loading phase. It entails ingesting 20 grams of creatine daily for 5–7 days to saturate your muscle cells rapidly, then 2–10 grams of creatine daily to sustain high levels.

This strategy can increase your muscle storage in one week or less.

Some people do a loading phase (which I’ll discuss in the next section more thoroughly). The theory is that you will see quicker results.

What Is The Correct Creatine Dosage?

The correct creatine dosage depends on your weight and if you decide to go on a loading phase first.

Loading phase means taking a lot of creatine before going into a maintenance dosage.

The usual recommendation is to consume 20-25 grams of creatine per day for about a week.

Once you complete the loading phase, or if you decide to forgo it entirely, then you can switch to the maintenance dosage.

An average dosage is between 3-5 grams of creatine per day. You can calculate how much you should consume by taking your weight and multiplying it by 14mg per pound.

Does Creatine Have To Be Taken With Sugar?

Does Creatine Have To Be Taken With Sugar

No, creatine supplementation doesn’t have to be taken with sugar to benefit your skeletal muscle cells.

I know people though who would refuse to take creatine without some sweetener. Creatine supplements can have a bitter taste.

A lot of companies add sugar to their formula to help with the taste. If that appeals to you, then go for it.

Try to avoid artificial sweeteners because they have some potential health issues linked to them.

Does Caffeine Affect Creatine Negatively?

Caffeine can affect creatine negatively. If you consume too much caffeine, you dehydrate yourself. This could affect creatine’s ability to give you a powerful gym performance.

The research is inconclusive, but it’s worth noting.

On a related note, one study did suggest that creatine supplementation and caffeine only caused mild indigestion in a few people [3].

Final Thoughts

Dehydration is a serious issue, but you don’t have to drink extra water when using creatine.

Of course, when you workout and sweat, it can cause your body to lose fluids. Take the time to check in with yourself while you exercise to see if you feel less hydrated than average. If so, drink water to avoid becoming dehydrated.

You should increase your water intake every time you exercise to prevent unwanted side effects, such as muscle cramping. Your body muscle mass will thank you every day when you drink water to stay hydrated.
