Creatine: No Longer Just for Bodybuilders – A Science-Backed Supplement for Everyone

For decades, creatine has been associated with as a supplement for bodybuilders and serious gym enthusiasts. But here’s what the latest research reveals: creatine is actually one of the most versatile and well-researched supplements available, offering remarkable health benefits and performance boost.

Whether you’re an endurance athlete, someone wanting to lose weight, an older adult concerned about cognitive health, a woman navigating hormonal changes, or simply someone who doesn’t eat meat – creatine might be exactly what you need. Let’s dive into the science.

What Is Creatine and Why Does It Matter?

Creatine is a naturally occurring compound that your body produces from amino acids. It’s stored primarily in your muscles (about 95%) and used to produce ATP – the energy currency your cells need for quick bursts of activity. While your body makes some creatine and you get it from meat and fish, supplementation can significantly increase your muscle stores, leading to benefits that extend far beyond the gym.

The Well-Known Benefits: Strength and Muscle

Let’s start with what creatine is famous for:

Muscle Building & Strength Gains 

A July 2024 systematic review found impressive results: people under 50 yo. who took creatine gained on average 2.5 pounds more muscle while they also lost 1.5 pounds more fat compared to placebo groups.

An October 2023 study showed creatine supplementation allowed for approximately:

Why the difference? Your legs have more creatine receptors and transporters, making them especially responsive to supplementation.

The Game-Changing Discovery: Benefits for Everyone

1. Endurance Athletes and Metabolic Health

Surprise! Creatine isn’t just for short bursts of power. A 2023 meta-analysis revealed that creatine improved both anaerobic AND aerobic performance. Here’s how:

This means faster recovery between training sessions and better overall performance, whether you’re a short or long-distance athlete.

2. Brain Health and Cognitive Function

Your brain uses creatine too! Creatine provides instant energy for your brain, leading to:

Improved Memory & Focus:

Better Stress & Sleep Deprivation Management:

3. Women’s Hormonal Health – A Critical Discovery

This is huge: emerging research shows creatine offers unique benefits for women throughout their lifespan:

During Menstrual Cycle:

Perimenopause & Menopause: Recent 2025 research highlights creatine as particularly beneficial during this transition:

The Science Behind It

Women have about 10% higher baseline muscle creatine than men but produce 70-80% less endogenous creatine. This makes supplementation especially beneficial. A 2024 study found that women consuming adequate dietary creatine had a lower risk of reproductive disorders, including oligomenorrhea and pelvic conditions.

4. Bone Health – Especially Important as We Age

A 2024 study revealed something fascinating: while creatine didn’t necessarily increase bone density, it improved bone cell remodeling – especially in the femur. This makes bones more fracture-resistant by encouraging bone cells to adapt and strengthen in response to mechanical load.

Combined with resistance training, this is particularly valuable for postmenopausal women and older adults.

5. Immune System Support

Recent research shows creatine increases white blood cell production, improving immune response and reducing systemic inflammation. This has implications for:

6. For Vegetarians – A Critical Supplement

Since creatine is found primarily in animal products, vegetarians typically have 30-40% lower muscle creatine stores. Research shows these individuals may experience even greater benefits from supplementation than meat-eaters, with more pronounced improvements in:

For plant-based eaters, creatine supplementation isn’t just beneficial – it’s essential for optimal function.

7. Weight Loss Support

Here’s an unexpected benefit: the July 2024 review that showed muscle gain also found participants lost more fat when taking creatine. Creatine supplementation increases lean body mass and reduces body fat percentage. Researchers believe reduced inflammation allows for more efficient fat oxidation and lipolysis (fat breakdown).

What if Creatine Makes You Bloated?

Many people avoid creatine because of bloating, but here’s the breakthrough: the puffiness may not be from taking too much creatine, but from not enough sodium.

The primary transporter for creatine (SLC688) is a sodium-dependent transporter. Studies show up to 47% better increase in muscle creatine when taken with a little salt.

What happens without salt: Low sodium means creatine doesn’t enter muscle cells efficiently, so it stays in extracellular spaces, causing that puffy feeling. A pinch of good quality salt or electrolytes with your creatine helps it go where it should – into your muscles.

Dosing Guide: How Much for Your Goal

If you’re new to using creatine, you can either choose to do a loading phase (to access the benefits a bit faster) or simply use same daily doses and eventually accumulate the creatine level in your body. For the loading use 20g of creatine per day for 7 days (split into 4 doses of 5g). Then continue with a maintenance dose according to your goal as shown below.

For Muscle Building, Improved Recovery and Strength:

For Brain Health & Cognitive Function:

For Women (Accounting for Higher Needs):

For People Over 50:

For Bone Health:

For Vegetarians/Vegans:

Safety: Addressing Health Concerns

Kidneys: Creatinine (a breakdown product) increases are normal and don’t indicate kidney damage. Multiple studies show no harm even at high doses in healthy individuals.

Liver: No issues at normal supplementation doses. Human data shows no harm.

The Bottom Line

Creatine monohydrate is one of the most researched, safe, and effective supplements available. It’s far more than a bodybuilding supplement – it’s a versatile compound that supports muscle, brain, bone, metabolic health, and hormonal balance across the lifespan.

The best part? It’s affordable, well-tolerated, and backed by decades of research. Whether you’re 25 or 65, athletic or sedentary, omnivore or vegetarian, creatine likely has something to offer you.
