If there’s one dietary supplement to invest in and actually reap the benefits, it’s creatine. Oh, and protein powder if you aren’t consuming enough high-protein foods.

The International Society of Sports Medicine¹ (ISSN) reports, “Creatine monohydrate remains one of the few nutritional supplements for which research has consistently shown has ergogenic [enhancing physical performance] benefits.”

There’s gotta be a catch, though… Right?

As with any supplement, there can be trade offs, but is creatine headaches one of them? Join us as we explore if creatine causes headaches and tips to help prevent them if so.

What Is Creatine?

Creatine is a compound the body can create from nonessential amino acids—glycine, arginine, and methionine—in the liver, pancreas, and kidneys. It’s naturally found in red meat and seafood and sourced from creatine supplements, including the widely popular and studied form creatine monohydrate¹.

RELATED: What Is Creatine?

Creatine is primarily stored in the skeletal muscles as phosphocreatine, which the body breaks down into adenosine triphosphate (ATP) for quick energy, especially during high-intensity activities and to initiate muscle contraction.

The ability to increase the capacity of ATP and energy produced during heavy, anaerobic exercise is why bodybuilders and fitness enthusiasts lean on creatine supplementation. The evidence-based benefits of creatine seem to outweigh the risks, but some potential side effects are worth exploring—but are headaches among them?

Potential Side Effects of Creatine Supplementation

Google Scholar your way through “creatine supplementation side effects,” and you’ll find creatine is consistently deemed safe and effective, including in a 2021 update published in Current Sports Medicine Reports².

Moreover, the International Society of Sports Nutrition¹ proposes both short-term and long-term creatine supplementation as safe and well-tolerated in healthy individuals throughout the lifespan—even in children³ and older adults.

However, despite most reputed creatine side effects being attributed to high doses or debunked as myth, the most common concerns include:

Weight gain, primarily due to fluid retention and subsequent water weight gain in lean mass rather than body fat.

Digestive issues, including bloating and stomach pain, mainly when containing a high dose of 10 grams based on this 2008 study.⁴

Muscle cramps and dehydration, although that myth⁵ has since been debunked. Research⁶ even hints creatine may help prevent muscle cramps and improve heat tolerance when taken properly.

Kidney damage, as creatine supplementation has been speculated to overwhelm the kidneys. However, a meta-analysis⁷ shows that creatine supplementation does not cause kidney damage.

If you noticed creatine headaches didn’t make the list, it’s because no sound evidence shows creatine is directly responsible for them and it’s not as wide-spread of a myth as some of the others. Some research even suggests creatine may reduce headaches—more on this coming up, so stick around for that!

This isn’t to say creatine users don’t experience headaches, but other contributing factors likely cause them. Let’s explore possible headache culprits if you experience headaches alongside your creatine dose.

How Might Creatine Cause Headaches?

While creatine doesn’t seem to cause headaches directly, people who take creatine are primarily active in sports, bodybuilders, or interested in optimizing their fitness and health. These individuals may experience headaches while taking creatine due to sports and fitness-related headache risks.

Headaches in Sports

A review published in Headaches⁸ reports up to 3.8 million people per year have a sports-related mild traumatic brain injury (TBI) frequently followed by various headaches. Moreover, a recent 2023 longitudinal study⁹ suggests a history of concussions significantly adds to the headache burden among American adolescents and young adults.

Sports-related headaches may be directly related to traumatic concussions and head injuries. Non-traumatic headaches associated with sports also include:

Exertional headaches evoked by sustained activities—like running and rowing—that become a greater risk with high altitude, hot weather, decreased fluid intake, and extreme exertion. Increased muscle power and endurance are benefits of creatine, as you’ll soon learn, so this could also intensify exertion.

Weightlifter’s headaches—also known as cough headaches—triggered by a Valsava maneuver¹⁰, or essentially holding a big breath to increase intra-abdominal pressure and spine stability while lifting.

External compression headaches, which can be caused by external pressure to the forehead and scalp like a tight hat, football helmet, or swim goggles.

Again, this is simply to say athletes are at great risk of headaches and theorizing they might supplement with creatine. (Correlation does NOT mean causation.)

Other Fitness-Related Headache Risks

Fitness-minded folks may also experience headaches while taking creatine due to other factors such as:

Hydration status: Despite inadequate evidence showing creatine causes dehydration, active individuals taking creatine may under- or overhydrate, which could trigger a headache.

Training environment: As mentioned with exertional headaches, high altitude and hot weather training environments can increase headache risk.

Caffeine intake: Headaches are among the most common pre-workout side effects athletes might experience. Caffeine can also cause insomnia, further increasing headache risk.

Muscle tension: Muscle tension, especially in the neck and shoulders, can induce tension-type headaches¹¹.

And, of course, we wouldn’t present risks without offering solutions! Fortunately, there are steps you can take and habits to adopt to help prevent “creatine headaches.”

How to Prevent Creatine Headaches

Because underlying health conditions can cause secondary headaches, you should first and foremost consult with a healthcare professional for your utmost safety. With that out of the way, these tips may prevent the risk of headaches and other creatine side effects:

Rethink the creatine loading phase, and adjust your creatine dosing if you’re still experiencing symptoms. (Here’s how to take creatine safely and effectively.)

Stay hydrated by drinking enough water and replenishing with the best electrolyte powders as needed, especially if training in intense weather environments.

Evaluate your pre-workout; some contain creatine, and you might consume more than needed. Also watch out for the caffeine content, especially if you consume from other sources like coffee, and consider trying out one of the best stim-free pre-workouts.

Dress appropriately and pay extra attention to the climate you’ll be training in to avoid overheating.

Don’t overexert yourself, especially if you’re not properly recovered, warmed up, hydrated, or experienced in a hot or high-altitude training climate.

Can Creatine Prevent Headaches?

Rather than causing headaches, creatine may actually help reduce them.

A small pilot study¹² shows creatine offers neuroprotective effects in children and adolescents with traumatic brain injuries. After creatine administration, specifically 0.4 grams of creatine per kilogram of body weight for six months—researchers found improvements in various parameters—like headaches, dizziness, and fatigue—in all patients (without side effects)!

A letter to the editor¹³ of the pilot study further suggests creatine loading—20 grams per day—significantly increases brain creatine levels in healthy individuals. The researchers also encourage that this should be verified in chronic migraine patients.

Moreover, the ISSN¹ feels that government legislatures and sport organizations who restrict and discourage creatine use may place athletes at greater risk, particularly in contact sports with a greater risk of head trauma and neurological injury.

The Benefits of Creatine

We can’t discuss potential side effects without addressing evidence-based creatine benefits, and many studies¹⁴ confirm it boosts fitness, athletic performance, and overall health. GGR senior staff writer and certified nutrition coach Amanda Capritto outlines 10 creatine benefits that’ll convince you to add it to your supplement stack:

Increases muscle strength, even in as little as four weeks¹⁵
Increases muscle power due to creatine’s role in ATP synthesis
Improves muscular endurance, particularly in high-intensity, short-burst movements during strength training
Produces more muscle growth in tandem with an adequate resistance training regimen
Expedites recovery time¹⁶ by reducing overall muscle damage and post-workout inflammation
Might reduce dehydration and muscle cramps despite alterations in water retention
May help stabilize blood sugar¹⁷, especially when combined with aerobic training
May be neuroprotective with neurological benefits, including in the treatment of Parkinson’s disease¹⁸
Improves brain function and health¹⁹ with more pronounced benefits in a challenged state, such as sleep deprivation
Fights fatigue, including general tiredness and fatigue during exercise

Overall, supplementing with creatine increases creatine muscle stores and is ideal for increasing muscle mass and size while improving physical performance.

Creatine Headaches: Final Thoughts

While some consumers report creatine headaches, no sound evidence proves creatine directly causes them. In fact, creatine may even reduce headaches!

But if headaches occur while taking creatine, they’re more likely related to dehydration, overexertion, overheating, and other risk factors. Athletes are also more likely to experience sports-related headaches related to traumatic concussions and head injuries.

While creatine might seem too good to be true, it’s one dietary supplement with a glowing track record backed by data. It can enhance your physical performance and may even augment your overall health, and comes with very few risks when dosed to individual needs.

Note: It’s essential to consult your doctor if headaches persist, especially if taking appropriate steps to prevent headache-related risks.

Creatine Headaches: FAQs

What is the biggest side effect of creatine?

The International Society of Sports Nutrition Position Stand¹ on the safety and efficacy of creatine supplementation suggests weight gain is the only consistently reported side effect in the literature. However, the weight gain is water weight gain, often short-lived, and unlikely to occur if following a low-dose yet effective protocol—about 3 to 5 grams daily.

Can creatine make you feel lightheaded?

While lightheadedness has been reported when taking creatine, there’s no actual evidence to confirm it causes it. Lightheadedness is, however, common after a concussion²⁰, and it may be triggered by dehydration, low blood sugar, and positional changes like standing up.

How much water should I drink with creatine?

How much water you should drink with creatine mostly depends on individual fluid needs. Generally, drink at least 8 ounces of water with a 3- to 5-gram creatine dose on top of routine water intake. If you’re creatine loading, drink at least 32 to 40 ounces of water with the supplement doses in addition to your daily water intake.

What happens when you stop creatine?

When you stop taking supplemental creatine, the levels in your body will start to decrease in its absence. How long creatine stays in your system depends on several factors, but research²¹ shows stopping creatine and reducing training volume may significantly reduce muscle endurance after 12 weeks. However, no effects on the rate of strength, endurance, and lean tissue loss are noted in this study.
