Creatine is one of the most researched supplements in the world — yet many people still misunderstand how it works or whether it’s safe
Creatine serves as an energy source for muscles. When performing demanding activities such as weightlifting or high intensity interval training (HIIT), creatine allows for higher levels of energy production by the body. [1]
While it is most commonly taken by athletes or gym members looking for increased endurance/strength, creatine has been shown to have significant impacts on the process of synthesizing protein within the body as well.
While the body produces creatine naturally, supplementing can help saturate muscle stores for optimal performance.
Energy Dynamics of Creatine
Storage and Usage:
-
You have probably heard the expression “Mitochondria are the powerhouses of the cell,“ this is because they produce ATP (Adenosine Triphosphate), otherwise known as the energy currency of any cell, meaning that if there is ample amount of ATP available in your body, your body will perform significantly better when working out. [1]
How your body holds onto it:
- In regards to the amount of creatine in your body: 95% of creatine found in your body is found in your muscles, and the remaining 5% is found throughout your brain.
- By maintaining higher creatine levels through supplementation, you create extra reserves that your body uses to produce more ATP.
- This not only maintains the energy levels during high-intensity activity but also benefits the overall output of training.
- The supplement also alters how cells operate, which aids in muscle development.
Supporting Muscle Development:
Creatine functions as a dual-purpose supplement: it enhances short-term energy availability for high-intensity efforts while promoting long-term increases in muscle mass and strength. Research shows it can benefit athletes, older adults seeking to preserve muscle, and even individuals with lower activity levels
The primary mechanism behind these gains is your body’s improved ability to regenerate ATP. During quick bursts of effort, your energy usually craters fast; creatine helps stretch that peak performance window just a bit longer. Extensive research proves that regular use significantly boosts:
- Muscle strength and endurance
- Overall explosive power and sprinting speed
- Jumping performance and recovery timing
- High-Intensity Performance: Stretching that “peak performance window.”
- Vegetarian Support: Providing a critical boost for those who don’t consume animal-based creatine.
Beyond the Gym: Brain Health & More
Just like your bicep muscle, the brain is a high-energy organ that requires rapid fuel to operate efficiently. Creatine supplementation has proven to be a powerful tool in neurological health and can potentially treat:
- Traumatic brain injuries and Epilepsy
- Neurodegenerative conditions like ALS (Amyotrophic Lateral Sclerosis)
- Short-term memory and cognitive “intelligence” scores in healthy adults [2]
- Potential benefits for blood sugar management and heart health
Creatine supplementation has possibly shown impressive results in boosting brain functions, this effect is often more pronounced in vegetarians and vegans who don’t get creatine from meat. Other potential benefits include the management of blood sugar levels, heart health, and strokes or non-alcoholic fatty liver disease.
Recent studies from Harvard indicate that the same energy reaction (creatine kinase) used by muscles is critical for orchestrating brain networks and enhancing cognitive fidelity. [5][6]
Should you consume Heme or Supplemental Creatine?
Understanding what to consume is crucial to maximize bioavailability. Bioavailability refers to the fraction of the nutrient that gets successfully absorbed and enters the bloodstream to get utilized.[4]

Your Guide to Starting Creatine:
If you’re looking for the most effective version, stick with Creatine Monohydrate. It is the most researched, affordable, and proven form available. While other “fancy” versions exist, they lack the same level of scientific backing.
You have two choices for putting creatine in your muscles:
- Loading Phase (Quickest): You may use 20g a day split into four lots of 5g each for 5-7 days. This is best when consumed with a high-protein or high-carb meal to promote absorption. After that you may want to switch to a maintenance dose of 3-5g per day.
- Direct Maintenance: If you’re not in a hurry, you may want to take 3-5g per day (by Mayo Clinic).
Safety and Side Effects of Creatine:
- In 2009, a rugby study started the DHT/hair loss rumor because of creatine but, evidence suggests the odds of this happening are very low and that creatine is a safe product when used appropriately and by otherwise healthy individuals (provided you are indeed otherwise healthy).
- Health experts reviewed by Harvard clarify that the 2009 study on misconceptions of creatine only showed a rise in DHT (a hormone linked to baldness) but did not actually measure or prove any hair loss. [8]
- There’s no strong correlation between creatine and developing dehydration or liver disease.
Another myth that is popularly discussed is the concern regarding kidney health. - While creatine is safe for healthy people, individuals with pre-existing kidney disease or those taking medications that affect renal function should exercise caution.
[3][4]
The Bottom Line
Creatine is one of the safest and most effective supplements for increasing muscle mass,
strength, and cognitive performance. For best results, use 3–5g of Creatine Monohydrate
daily, stay well-hydrated, and choose the loading phase only if you need immediate results.
