How To Reduce The Likelihood of Stomach Problems When Taking Creatine?

Nobody wants to get digestive issues, especially if they are going to interfere with your workouts. So, how to stop stomach pain from creatine? Here, we’ll go over 5 strategies to help you avoid stomach cramps and a supplement recommendation to decrease the risk of digestive issues. 

1. Use Micronized Creatine Monohydrate

As previously mentioned, not all forms of creatine are highly soluble in water. For example, while creatine monohydrate is the best option, it might not be the most soluble. As a result, undissolved creatine crystals can irritate the stomach wall and cause negative symptoms.

In this case, you might want to choose a creatine supplement that is highly soluble in water, such as micronized creatine monohydrate.

In simple terms, micronized creatine is one that has been broken down into smaller particles, making it more soluble and easier to absorb in the body.

2. Avoid Loading Phase

People who start taking creatine often do a loading phase to get the benefits of creatine quicker. While it is not necessary or mandatory, some find it helps speed up the process. The loading phase works by taking 20 to 25 grams of creatine for 5 to 7 days.

After the loading phase, you enter the maintenance phase, which is taking 3 to 5 grams of creatine daily as long as needed.

The problem is that by taking too much creatine it can increase the risk of digestive issues. So, if you want to avoid having stomach cramps, avoid doing the loading phase and just take your regular dose daily for 30 consecutive days. You’ll still get the same results, only for a longer time.

3. Take Creatine With Meals

Taking creatine with an empty stomach can increase the risk of digestive issues because the undissolved creatine particles will affect the stomach. For that reason, it’s best to take it with a meal, it may reduce the contact of creatine particles with the stomach.

In fact, evidence suggests that taking creatine along with some carbs and protein can increase its effect, such as greater strength outcome. For example, you can mix your creatine supplement with a protein shake (protein) and fruit (carbs).

4. Avoid Coingesting Creatine With High Fiber Foods

Now, you want to take creatine with foods, but you need to be careful on what type of foods you add. Eating high-fiber food can only increase the risk of stomach cramps if you are not used to a high fiber intake.

Fiber exerts a mechanical stimulation/irritation of the colonic mucosa with increased secretion and peristalsis, which itself may cause gastric discomfort in sensitive individuals. Since fiber reaches the intestines intact, the bacteria ferment it, causing gas. When there is gas buildup, it can lead to bloating and stomach cramps.

So, if you are not used to having high-fiber foods such as whole grains, legumes, and vegetables, do not increase their amount drastically while taking creatine. Add fiber-rich foods gradually and observe how much is well tolerated.

5. Drink More Water

Creatine needs a good water intake to function properly and for its digestion. If you don’t drink enough water, it increases the risk of stomach cramps. When taking creatine, make sure you drink plenty of water. Both at the time of taking creatine, as well as the rest of the day.

If you are already well hydrated, there is no need to significantly increase your water intake when incorporating creatine into your diet. For every 3-5g of creatine, about 8 ounces of water is sufficient. Pay close attention to your body’s signals and adjust your water intake as needed.

The specific amount of water to consume when using creatine can fluctuate depending on factors such as body size, activity level, and overall hydration needs. If you don’t know how much daily water you need, consult with a health professional to get some guidance based on your goals and needs.
