Creatine is a supplement that has gained immense popularity among athletes, bodybuilders, and fitness enthusiasts.

Its reputation as a performance enhancer and muscle builder has made it a staple in the world of sports nutrition.

However, with popularity comes myths and misconceptions. In this article, we’ll delve into what creatine is, how it works, its various types, and its benefits.

We’ll also address common misconceptions, dosages, safety concerns, and who can benefit from its use.

What is Creatine?

Creatine is a natural substance present in muscle cells that aids in the generation of energy when performing intense workouts or lifting heavy weights.

So Creatine is a naturally occurring compound found in small amounts in certain foods and synthesized in the liver, kidneys, and pancreas. It plays a crucial role in energy production during high-intensity, short-duration activities such as weightlifting, sprinting, and jumping.

How Does Creatine Work?

The use of creatine as a supplement is highly favored by athletes and bodybuilders for its ability to promote muscle growth, boost strength, and enhance overall exercise performance.

From a chemical perspective, creatine exhibits numerous resemblances to amino acids, which are vital compounds responsible for protein synthesis in the body. Your body has the capacity to synthesize creatine from the amino acids glycine and arginine.

Approximately half of your body’s creatine reserves originate from dietary sources, particularly red meat and seafood. The remaining portion is synthesized in your liver and kidneys using amino acids.

To understand creatine’s mechanism, you need to know that our cells store energy in the form of a molecule called adenosine triphosphate (ATP). During intense physical efforts, ATP is rapidly broken down to release energy. Creatine phosphate, a stored form of creatine, helps replenish ATP, allowing you to sustain high-intensity activities for longer.

Creatine also contributes to muscle gain through the following mechanisms:

  • Enhanced Workout Capacity: It allows for increased total work or volume during a single training session, which is a critical factor for long-term muscle growth (6).
  • Improved Cell Signaling: Creatine can boost satellite cell signaling, aiding in muscle repair and the development of new muscle tissue (7).
  • Elevation of Anabolic Hormones: Studies have shown an increase in hormones like IGF-1 following creatine supplementation.
  • Augmented Cell Hydration: Creatine increases the water content within your muscle cells, leading to cell volumization, which may play a role in muscle growth (8).
  • Reduction in Protein Breakdown: Creatine may enhance overall muscle mass by decreasing muscle breakdown.
  • Decreased Myostatin Levels: Elevated levels of the protein myostatin can hinder or slow down new muscle growth. Creatine supplementation can lower myostatin levels, thereby increasing the potential for muscle growth (9).

Creatine supplements also raise the levels of phosphocreatine in the brain, potentially supporting brain health and alleviating symptoms of neurological conditions (10).

Creatine provides extra energy to your muscles and induces cellular changes that promote muscle growth.

Creatine Types: Monohydrate vs. Other Forms

Creatine monohydrate is the most researched and widely used form of creatine. It is cost-effective and has proven effectiveness. Other forms, such as creatine ethyl ester and creatine nitrate, claim faster absorption, but scientific evidence supporting these claims is limited.

Benefits of Creatine Supplementation

Enhanced Exercise Performance

Creatine has been shown to improve performance in high-intensity, short-duration activities. This includes lifting heavier weights, sprinting faster, and completing more repetitions.

Increased Muscle Mass

Creatine helps increase water content in muscle cells, leading to a temporary increase in muscle size. Over time, it can also promote muscle protein synthesis, contributing to muscle growth.

Improved Brain Function

Emerging research suggests that creatine may have cognitive benefits, including enhanced memory and mental clarity.

Potential Therapeutic Uses

Some studies indicate creatine’s potential in treating certain medical conditions like muscular dystrophy, Parkinson’s disease, and depression. However, more research is needed.

Creatine’s Impact on Muscle Growth Can be Explained as follows:

  • Creatine has a positive impact on muscle growth, benefiting individuals with various activity levels, including sedentary individuals, older adults, and elite athletes.
  • A review conducted in 2022 confirmed the effectiveness of creatine supplements in promoting muscle development in healthy young adults.
  • Furthermore, a review from 2019 concluded that creatine, whether used in conjunction with resistance training or not, can enhance muscle mass and strength in older adults while also potentially reducing the risk of falls.
  • While older studies suggested that creatine could stimulate muscle fiber growth 2-3 times more effectively than training alone, more recent research has shown more moderate results.
  • Nonetheless, a comprehensive review of popular supplements identified creatine as the most effective supplement for increasing muscle mass.

Taking creatine supplements can lead to substantial gains in muscle mass, a benefit that applies to both inexperienced individuals and elite athletes.

Regarding strength and performance during physical activities:

Creatine also has the potential to enhance strength, power, and performance in high-intensity exercise. Several studies have demonstrated that creatine can:

  1. Increase muscle strength and endurance in young adults engaged in resistance training.
  2. Provide an extra burst of power for cyclists during the final sprint in a time trial.
  3. Enhance jumping and sprinting performance in soccer players.
  4. Improve power development in swimmers, particularly benefiting those in butterfly and breaststroke events.

These notable enhancements are primarily attributed to the increased capacity of the body to produce ATP (adenosine triphosphate).

Normally, ATP becomes depleted after approximately 10 seconds of high-intensity activity.

However, by augmenting ATP production, creatine supplements enable individuals to sustain optimal performance for a few seconds longer.

Creatine ranks among the top supplements for enhancing strength and high-intensity exercise performance. Its mechanism of action involves boosting your ability to generate ATP energy.

Creatine’s Impact on Brain Function

Creatine’s influence on the brain is noteworthy. Much like muscles, the brain relies on phosphocreatine and a substantial supply of ATP for optimal functioning.

Preclinical studies, primarily conducted on animals, have suggested that creatine supplementation may hold promise in the treatment of:

  1. Neurodegenerative diseases, such as Alzheimer’s disease and Parkinson’s disease.
  2. Amyotrophic lateral sclerosis (ALS).
  3. Traumatic brain injuries.
  4. Epilepsy.

Human studies have also indicated benefits for various populations. In a 2020 review, creatine supplements were found to enhance cognitive function in vegetarians. Vegetarians often have lower creatine levels due to their meat-free diet, which is a primary natural source of creatine.

Even in healthy adults, creatine supplementation may lead to improvements in short-term memory and cognitive abilities, with the most pronounced effects observed in older adults.

Creatine has the potential to alleviate symptoms and decelerate the advancement of certain neurological diseases; however, further research involving humans is required to substantiate these findings.

Other Health Benefits

Research also suggests that creatine may:

  • Lower blood sugar levels
  • Aid in the treatment of nonalcoholic fatty liver disease
  • Contribute to heart health
  • Diminish damage associated with strokes

Debunking Creatine Myths

Creatine and Kidney Damage

Contrary to popular belief, extensive research shows that creatine supplementation, when used as directed, does not harm healthy kidneys.

Creatine and Dehydration

Creatine can cause an initial increase in body weight due to water retention. However, this does not lead to dehydration when sufficient water intake is maintained.

Creatine as a Steroid

Creatine is not a steroid. It is a naturally occurring compound, and its use is legal in sports.

Dosage and Timing

Many individuals who use creatine supplements often begin with a loading phase, which leads to a swift buildup of creatine within the muscles.

To initiate the loading process, consume 20 grams of creatine daily for a span of 5 to 7 days. Divide this into four equal 5-gram servings distributed throughout the day.

Consuming a meal rich in carbohydrates or protein can aid in the absorption of creatine by the body.

Following the loading phase, maintain elevated muscle creatine levels by taking 3 to 5 grams daily. Since there is no added benefit to cycling creatine, this dosage can be sustained for an extended period.

If you opt not to undergo the loading phase, simply take 3 to 5 grams of creatine daily. However, it may take up to 4 weeks to fully maximize your creatine stores.

As creatine has the effect of drawing water into your muscle cells, it is advisable to ingest it with a glass of water and ensure adequate hydration throughout the day.

For a creatine loading phase, ingest 5 grams four times a day for a period of 5 to 7 days. Following this, a maintenance dose of 3 to 5 grams per day should be taken to sustain appropriate levels.

Creatine Loading Phase: Is It Necessary?

While some advocate for a loading phase (20 grams per day for a week), it’s not mandatory. You can achieve the same benefits with a lower daily dose over time.

Side Effects and Safety

Creatine is generally safe when used within recommended doses. Side effects may include mild gastrointestinal discomfort or muscle cramps in some individuals.

Creatine stands as one of the most extensively researched supplements, with studies spanning up to four years revealing no adverse effects.

There is no compelling evidence to suggest that creatine poses a risk to the liver and kidneys in individuals of good health who adhere to standard dosages. Nevertheless, individuals with preexisting liver or kidney issues should seek medical advice before considering supplementation.

Contrary to the common belief associating creatine with dehydration and muscle cramps, scientific research does not substantiate this connection. In fact, studies propose that creatine may actually reduce the occurrence of cramps and dehydration during endurance exercises conducted in high-temperature conditions.

A single study from 2009 found a potential association between creatine supplements and an increase in a hormone called DHT, which could contribute to hair loss. However, the majority of available research does not support this link.

Creatine is free from adverse side effects. Despite the prevalent belief that it triggers dehydration and muscle cramps, scientific research does not substantiate this claim.

Creatine and Dietary Sources

Small amounts of creatine can be obtained from red meat and seafood. However, to experience its full benefits, supplementation is often necessary.

Who Can Benefit from Creatine?

Creatine is beneficial for athletes, bodybuilders, and anyone involved in high-intensity activities. It can also be considered by individuals seeking cognitive enhancement or those with specific medical conditions under medical supervision.
