Over 1000 studies 

Creatine is one of the most popular and widely studied supplements, especially among athletes and fitness enthusiasts. It's a naturally occurring compound found primarily in muscle cells and is involved in producing energy during high-intensity exercise. Here are the key benefits of creatine supplementation:

What is Creatine?  

Creatine is a naturally occurring compound primarily stored in the muscles and brain. It is synthesized in the body from amino acids—arginine, glycine, and methionine—and is also available through dietary sources, particularly red meat, fish, poultry, pork, eggs. Creatine plays a critical role in cellular energy production, serving as a quick source of ATP (adenosine triphosphate), the body's primary energy currency.

 The total ATP production attributed to the Krebs cycle, including the ATP generated from the electron transport chain, is approximately 10 ATP per glucose molecule (2 ATP directly from the Krebs cycle and 8 ATP from the electron transport chain).

1. Hormonal Health and Energy Support

Women often experience hormonal fluctuations that can affect energy levels, particularly during perimenopause, menopause, and the luteal phase of the menstrual cycle. Creatine has been shown to enhance mitochondrial function and energy production, potentially alleviating fatigue associated with these hormonal changes.

1. Improved Exercise Performance -  5% to 15%

• Increased Power Output: Creatine helps replenish ATP (adenosine triphosphate), the primary energy carrier in cells, especially during short bursts of high-intensity activity. This leads to better performance in activities like weightlifting, sprinting, or high-intensity interval training (HIIT).

• Enhanced Strength: Creatine has been shown to improve strength and muscle power, allowing athletes to lift heavier weights or perform more reps, which can help in muscle growth over time.

• Increased Endurance: While creatine is more beneficial for short bursts of energy, some studies show that it can also slightly improve endurance during activities like running or cycling when performed at higher intensities.

2. Supports Muscle Growth - Creatine supplementation can increase muscle growth by about 25-33% over time compared to not taking it

• Increased Muscle Mass: Creatine is known to promote muscle hypertrophy (muscle growth) through several mechanisms:

  • Increased Water Retention in Muscles: Creatine causes muscle cells to retain water, making muscles look fuller and more volumized, especially early on.

  • Enhanced Protein Synthesis: It may also increase the activity of satellite cells, which are involved in muscle repair and growth.

  • Improved Workout Performance: By allowing you to lift heavier or perform more reps, creatine can contribute to greater overall training volume, which is a key driver of muscle growth over time.

Creatine has been studied for its potential benefits in treating conditions like muscular dystrophy, heart disease, diabetes, and neurodegenerative diseases.

Research is also ongoing in its potential use in improving bone health and as a supplement for elderly populations to help maintain muscle mass and function.

3. Brain Function and Cognitive Benefits

• Improved Cognitive Performance: Creatine may help with cognitive functions, particularly tasks requiring short-term memory, quick thinking, and decision-making. This is because the brain also uses ATP for energy, and creatine supplementation may help support energy production in brain cells.

• Neuroprotection: Some research suggests that creatine might have neuroprotective effects, potentially benefiting people with neurodegenerative conditions like Parkinson's, ALS, or Alzheimer's. It may help protect brain cells from damage by improving energy availability in the brain.

Recent research has also investigated the role of creatine in brain health, particularly in conditions like Parkinson’s disease, Alzheimer’s, and depression, as well as its effects on cognitive performance and mental fatigue.

4. Faster Recovery - creatine monohydrate (CrM) supplementation significantly reduced indirect muscle damage markers (such as creatine kinase, lactate dehydrogenase, and myoglobin) at 48-90 hours post-exercise. Additionally, it lowered inflammation and oxidative stress markers at 24-36 hours and 48-90 hours post-exercise, with large effect sizes. Delayed-onset muscle soreness (DOMS) was also lower for the CrM group at 24 hours post-exercise, with a moderate effect size.

• Reduced Muscle Damage: Creatine may help reduce muscle damage and inflammation after intense exercise, which can lead to faster recovery times between workouts.

• Reduced Muscle Soreness: Some studies suggest that creatine can reduce delayed onset muscle soreness (DOMS) after strenuous exercise, leading to quicker recovery and less discomfort after workouts.

5. Supports Healthy Aging

• Muscle Preservation: As we age, muscle mass tends to decline, a condition known as sarcopenia. Creatine may help counteract this by preserving lean muscle mass and improving strength, which is particularly beneficial for older adults to maintain mobility and quality of life.

• Improved Bone Health: Some evidence suggests that creatine might support bone health by improving muscle strength, which can reduce the risk of falls and fractures in older adults.

6. Improved Performance in Explosive Sports

• Creatine is especially effective for activities involving short bursts of high-intensity activity—such as sprinting, football, baseball, and high-intensity interval training (HIIT). The increase in available ATP means you can maintain peak performance for longer during intense, explosive movements.

7. Potential Weight Gain

• Many people experience weight gain with creatine supplementation, but it’s typically due to water retention in the muscles, which is often temporary. However, the increased ability to train harder can lead to long-term muscle gains, which will contribute to lean body mass over time.

8. May Improve Glucose Metabolism

• There’s some emerging evidence suggesting that creatine supplementation may improve insulin sensitivity and glucose metabolism, which could be beneficial for individuals with type 2 diabetes or those at risk of developing it. However, more research is needed in this area.

How Creatine Works:

1. Energy Production (ATP): Creatine is stored in the muscles as creatine phosphate. During high-intensity exercise, creatine phosphate donates a phosphate group to ADP (adenosine diphosphate), regenerating ATP (the primary energy currency of the cell) and allowing for continued muscle contraction.

2. Cell Volumization: Creatine draws water into muscle cells, which can increase the size of muscle fibers temporarily, making muscles appear larger and fuller.

3. Protein Synthesis: Creatine can influence the activation of certain pathways related to protein synthesis, helping promote muscle growth.

Common Forms of Creatine:

• Creatine Monohydrate: The most researched and commonly used form of creatine. It is effective, widely available, and inexpensive.

• Creatine HCL (Hydrochloride): A more soluble form that some people find causes less bloating or water retention, but the benefits are similar to creatine monohydrate.

• Creatine Ethyl Ester: Another variation with claims of better absorption, but less evidence supports this form compared to creatine monohydrate.

How to Take Creatine:

• Loading Phase (optional): Take 20 grams per day (divided into 4 doses of 5 grams) for 5-7 days to saturate your muscles more quickly.

• Maintenance Phase: After the loading phase (or if skipping it), take 3-5 grams per day. This will maintain creatine levels in the muscles.

• Timing: Creatine can be taken at any time of day, but it’s often recommended to take it post-workout with a carbohydrate source to enhance uptake into muscles. However, studies suggest it’s not critical to take it at a specific time.

Choosing the Right Creatine 

When selecting a creatine supplement, consider the following:  

- Purity: Look for high-quality creatine monohydrate, the most studied and effective form.  

- Additives: Avoid products with unnecessary fillers or artificial ingredients.  

• Third-Party Testing: Ensure the supplement has been tested for purity and potency by an independent laboratory.

Safety and Side Effects:

• Generally Safe: Creatine is generally considered safe for most people when taken in recommended doses. Extensive research has shown that it doesn't cause kidney damage in healthy individuals, despite past concerns.

• Possible Side Effects:

  • Water Retention: Creatine causes muscles to hold more water, which can lead to some weight gain and a “puffy” appearance.

  • Digestive Issues: Some individuals experience bloating or gastrointestinal discomfort, especially during the loading phase.

  • Muscle Cramps: Though rare, some people report muscle cramps, though the evidence linking creatine to cramps is weak.

• Consult with a Doctor: If you have any pre-existing kidney conditions, it's a good idea to check with a healthcare professional before taking creatine.

• Kidney stress

Why It Happens: Some research suggested that creatine supplementation might strain the kidneys, especially with long-term use or in those with pre-existing kidney conditions.

Who Is At Risk: For healthy individuals, there is no evidence that creatine causes kidney damage when taken in recommended doses. However, people with pre-existing kidney conditions should consult with a healthcare provider before using creatine.

Dehydration

• What It Is: Because creatine causes your muscles to hold more water, it could potentially lead to dehydration if you're not drinking enough fluids.

• Why It Happens: Creatine's effect on water retention can reduce the available fluid elsewhere in the body.

• How to Avoid It:

  • Drink plenty of water: Ensure you are consuming enough fluids throughout the day, especially if you’re engaging in intense exercise.

Electrolyte Imbalance

• What It Is: When your body holds more water in the muscles, it can alter the balance of electrolytes like sodium, potassium, and magnesium, leading to imbalances that could cause symptoms like muscle cramps or fatigue.

• Why It Happens: Creatine supplementation can affect fluid balance and may indirectly alter electrolytes.

• How to Avoid It:

  • Make sure you are hydrating properly and consider supplementing with electrolytes if you're experiencing cramping or fatigue.

Possible Interaction with Medications

• What It Is: Creatine could potentially interact with certain medications, such as diuretics (which cause the body to excrete more water) or medications for kidney or liver issues.

Potential Increase in Blood Pressure (Rare)

• What It Is: While rare, some people report a slight increase in blood pressure with creatine supplementation.

• Why It Happens: Creatine can cause water retention, which may increase blood volume and potentially raise blood pressure, particularly in those who are sensitive to changes in hydration status.

Integrating Creatine Into a Functional Medicine Approach 

Creatine is most effective when combined with a holistic approach to health. This includes:  

- Nutrition: A nutrient-dense, anti-inflammatory diet rich in whole foods.  

- Exercise: Resistance training and weight-bearing exercises to maximize muscle and bone benefits.  

- Stress Management: Practices such as breath work, yoga, or meditation to complement creatine’s cognitive and mood-enhancing effects.  

- Individualized Care: Monitoring hormone levels and overall health to tailor supplementation to a woman’s unique needs.  

Conclusion:

Creatine is a well-researched supplement with a broad range of benefits, especially for those involved in high-intensity exercise, strength training, or explosive sports. It can enhance performance, support muscle growth, aid recovery, and even improve cognitive function in some cases. For most people, creatine is safe and effective when taken in appropriate doses, and it remains one of the most trusted and cost-effective supplements in the fitness and sports world.
