10 Common Questions and Misconceptions about Creatine Supplementation Answered By Doctors!

Table of Contents

Creatine is a naturally occurring compound found in our bodies and obtained through dietary sources such as meat. It plays a vital role in energy metabolism, particularly in high-intensity, short-duration activities.

Creatine supplementation has gained significant popularity among athletes and individuals engaging in physical exercise due to its potential to enhance muscle mass, performance, and recovery.

However, despite the extensive scientific literature on creatine, several questions and misconceptions still persist regarding its efficacy and safety.

In this blog post, we aim to address these common questions and debunk some of the prevailing misconceptions about creatine supplementation.

 

Question 1: Does creatine cause kidney damage/renal dysfunction?

Concerns about the potential adverse effects of creatine supplementation on kidney function have been prevalent.

However, extensive research conducted over the past two decades provides strong evidence that creatine supplementation at recommended dosages does not cause kidney damage or renal dysfunction in healthy individuals.

Studies have shown that transient increases in blood or urinary creatine and creatinine levels due to supplementation are unlikely to reflect a decrease in kidney function.

Individuals with pre-existing kidney conditions or those taking specific medications should exercise caution, but for the general population, creatine supplementation does not pose a risk to kidney health when used as directed.

 

Question 2: Is creatine an anabolic steroid?

No, creatine is not an anabolic steroid. Anabolic steroids are synthetic versions of testosterone that enhance muscle mass and strength by increasing muscle protein synthesis.

Creatine, on the other hand, is a naturally occurring compound that can be found in meat and is also produced by our body.

While the physiological and performance outcomes of anabolic steroids and creatine supplementation may be similar, their mechanisms of action and legal categorization differ significantly.

Anabolic steroids are controlled substances regulated by drug enforcement agencies, whereas creatine is considered a dietary supplement. It is important to understand that creatine is not classified as an anabolic steroid.

 

Question 3: Does creatine lead to water retention?

One common misconception surrounding creatine supplementation is the belief that it leads to water retention.

While early research showed that high-dose creatine supplementation could cause temporary water retention, more recent studies indicate that this effect is only observed in the initial stages and does not persist in the long term.

The increase in water retention is primarily due to creatine’s osmotic properties, which may cause intracellular water uptake. However, studies have shown that prolonged creatine supplementation at recommended dosages does not significantly alter total body water or extracellular water relative to muscle mass.

Hence, it is unlikely that creatine supplementation leads to water retention.

 
 

Question 4: Does creatine cause hair loss/baldness?

The belief that creatine supplementation leads to hair loss or baldness stems from a single study that reported increased dihydrotestosterone (DHT) levels in male rugby players after creatine supplementation.

However, this study has not been replicated, and other research has not shown a causal relationship between creatine supplementation and hair loss.

While the increase in DHT levels observed in that study is within normal clinical limits and does not indicate hair loss, it is important to note that individual responses may vary. Overall, the current evidence suggests that creatine supplementation does not cause hair loss or baldness.

 

Question 5: Does creatine lead to dehydration and muscle cramping?

Another misconception is that creatine supplementation causes dehydration and muscle cramping. However, scientific research does not support this claim.

While early speculation suggested that creatine’s osmotic properties could potentially disrupt fluid balance and increase the risk of dehydration and muscle cramping, numerous studies have demonstrated that creatine supplementation does not lead to dehydration or increased muscle cramping.

In fact, some research even suggests that creatine supplementation may enhance hydration status and reduce the risk of heat-related illnesses in athletes exercising in hot and humid environments.

Therefore, concerns about dehydration and muscle cramping should not deter individuals from using creatine as a supplement.

 

Question 6: Is creatine harmful for children and adolescents?

Creatine supplementation has been a topic of concern for children and adolescents. However, the available evidence indicates that creatine supplementation is safe and potentially beneficial for younger populations.

Studies have shown that creatine supplementation can improve muscle mass, strength, and exercise performance in adolescents, provided it is used at recommended dosages.

It is important to note that creatine supplementation should be used under adult supervision and within appropriate guidelines.

As with any dietary supplement, caution should be exercised to ensure proper dosage and adherence to safety guidelines.

Question 7: Is a creatine ‘loading-phase’ required?

One misconception about creatine supplementation is that a ‘loading phase’ is necessary to achieve its benefits.

A loading phase typically involves consuming higher doses of creatine (e.g., 20 g/day) for several days, followed by a lower ‘maintenance’ dose (e.g., 3-5 g/day). However, research indicates that a loading phase is not essential for experiencing the benefits of creatine supplementation.

Studies have shown that daily supplementation with lower doses of creatine (3-5 g/day) over a period of several weeks can lead to similar increases in muscle creatine content as the loading phase.

While a loading phase may result in more rapid increases in muscle creatine content, it is not necessary for sustained benefits.

 
 

Question 8: Does creatine increase fat mass?

Contrary to popular belief, creatine supplementation does not lead to an increase in fat mass.

Research consistently shows that creatine supplementation, even in longer-term studies, does not cause an increase in fat mass.

While some temporary weight gain may occur during the initial stages of creatine supplementation due to water retention, this does not translate into an increase in fat mass.

Studies have demonstrated that creatine supplementation, when combined with resistance training, can actually promote improvements in body composition by increasing lean muscle mass and strength.

 

Question 9: Is creatine beneficial for older adults?

Creatine supplementation has shown great promise in benefiting older adults, particularly in combating age-related muscle loss and improving exercise performance.

Research suggests that creatine supplementation, when combined with resistance training, can enhance muscle mass, strength, and functional performance in older adults.

It may also have positive effects on bone health in postmenopausal females when combined with resistance training.

Creatine supplementation appears to be a safe and effective strategy for older adults to improve muscle quality, functionality, and potentially mitigate the negative effects of aging on musculoskeletal health.

 

Question 10: Is creatine only effective for resistance/power-type activities?

Contrary to the misconception that creatine is only effective for resistance or power-type activities, there is growing evidence to suggest that creatine supplementation can benefit a variety of athletic activities.

While initial research primarily focused on its benefits for athletes involved in high-intensity intermittent activities, more recent studies have demonstrated positive effects of creatine supplementation in areas such as glycogen storage, muscle damage and recovery, injury prevention, heat tolerance, and neurological disorders.
