"It's just for bodybuilders." 

"It'll damage your kidneys." 

"Women shouldn't take it."

If you've ever considered trying creatine, chances are you've heard at least one of these warnings from a well-meaning friend or read them in some corner of the internet. With so much conflicting information out there, it's no wonder many people feel hesitant about this popular supplement.

But here's the thing: while internet bros and gym mythology have been busy spreading misinformation, scientists have quietly conducted over 1,000 studies on creatine, making it one of the most thoroughly researched supplements on the planet (1). What they've discovered might surprise you.

In this myth-busting blog, we're diving deep into the science behind creatine to separate fact from fiction once and for all. Whether you're a fitness enthusiast, weekend warrior, or simply someone wanting to prioritize your health, what you're about to learn could be a game-changer for your physical and mental performance.

Myth #1: Creatine Is Only for Bodybuilders & Athletes

The Real Story: Thinking creatine is just for bodybuilders is like believing sunscreen is only for lifeguards. Creatine is beneficial for virtually everyone, from elite athletes to grandparents.

Creatine works like a cellular battery charger for your muscles. Your body's energy currency (ATP) gets depleted during intense activity, and creatine helps recharge it faster (2). 

This isn't just helpful for lifting weights—it benefits (3, 4, 5):

  • Brain function: Studies suggest potentially improved memory and processing speed, especially under stress or fatigue.
  • Everyday activities: From carrying groceries to climbing stairs, creatine may help power daily movements.
  • Aging adults: Research indicates creatine may help preserve muscle mass and cognitive function as we age.
  • Vegetarians and vegans: Since natural creatine comes mainly from meat, plant-based eaters often see even greater benefits from supplementation.

Myth #2: Women Shouldn't Take Creatine

The Real Story: Suggesting women shouldn't take creatine is like saying women shouldn't strength train—it's outdated advice that ignores both science and the diverse fitness goals women have.

This myth likely stems from several misconceptions:

  • That creatine will make women "bulky". 
  • That women don't need or benefit from increased power output.
  • That women's hormonal profiles make creatine less effective.

Research tells a completely different story (6, 7, 8, 9, 10):

  • Equal benefits: Studies suggest women experience the same performance improvements as men—about 5-15% increases in strength and power output. 
  • No hormonal effects: Creatine doesn't contain hormones and doesn't directly influence testosterone or estrogen levels.
  • Body composition advantages: Women often see improved lean muscle retention while losing fat especially when combined with resistance training, helping achieve that "toned" look many desire.
  • Cognitive benefits: Female participants in studies show the same mental performance enhancements as males.
  • Bone health potential: Emerging research suggests creatine may support bone mineral density, particularly important for women as they age.

Myth #3: Creatine Makes You Gain Weight & Look Bloated

The Real Story: The initial weight gain from creatine is like upgrading your car's coolant system—it's not making the engine bigger, just improving its performance.

When you start taking creatine, your muscles pull in extra water—which is a good thing! However it may cause a temporary 2-4 pound weight increase (11). Think of your muscles as sponges that become more saturated and full.

This fluid retention (12):

  • Occurs primarily inside muscle cells (intracellular), not under your skin.
  • Actually helps with protein synthesis—like providing a better environment for building muscle.
  • Is not fat gain—your body composition typically improves with proper creatine use.

The scale might show a small increase, but what's happening is your muscles are becoming more efficient at generating energy. Most people report their muscles looking more 'full' rather than bloated.

If you’re still worried about gaining weight because of supplementing creatine, here are a few ways to decrease the chance of water retention. 

  1. Lower sodium intake: More sodium can make you retain more water, so if you want to keep that added water weight in check, monitor your daily sodium intake. The best way to help keep it down is relatively easy—cut out as many highly processed foods as possible.
  2. Lower carb intake: Similar to sodium, more carbs also means more water in the body. You need carbs for the energy they provide, but keep the level (and quality) of carbs you’re eating in check. 
  3. Drink more water throughout the day: Consuming more fluids means peeing more, which means you’re shedding excess water. 
  4. Don’t be so hard on yourself: Unless you’re competing in weight classed athletics or prepping for the stage at a bodybuilding competition, a couple pounds spread over your whole body will likely not even register for you, visually. Remember: it’s water, not fat mass. You’ll be fine. 

Myth #4: Creatine Will Damage Your Kidneys

The Real Story: Worrying about creatine damaging healthy kidneys is like fearing that rain will flood your house when the plumbing works perfectly.

The science on this is remarkably clear:

  • Multiple clinical studies spanning decades show no evidence of kidney damage in healthy individuals. However, creatine might be unsafe for women with pre-existing kidney problems. More research is needed A landmark review examining over 1,000 studies found creatine supplementation does not adversely affect kidney function in individuals with normal kidney function (13)
  • Your body naturally produces about 1-2 grams of creatine daily, and supplementation simply provides more of what your body already makes (14)

Your kidneys are designed to filter various compounds, including creatine's waste product creatinine. For healthy individuals, this process works smoothly even with supplementation.

Native Note: If you do have a history of kidney issues, it’s always best to consult your doctor or healthcare provider before starting creatine.

Myth #5: You Must "Load" Creatine With Massive Doses to See Results

The Real Story: Creatine loading is like taking the express lane on a highway—you'll get to the same destination either way, just a bit faster with the express route.

There are two effective approaches to creatine supplementation (15):

  • Loading protocol: 20-25g daily for 5-7 days, then 3-5g maintenance
  • Consistent approach: 3-5g daily from the start

Research shows both methods eventually achieve the same muscle saturation levels—loading just gets you there in days rather than weeks. It's like filling a swimming pool: you can use a fire hose (loading) or garden hose (consistent approach), but the pool fills completely either way.

Many people—including myself—prefer skipping the loading phase to avoid potential digestive discomfort. I’m happy to wait a few extra weeks for full benefits in exchange for a smoother start.

Myth #6: You Need to Cycle On & Off Creatine

The Real Story: The "cycling" recommendation for creatine is like suggesting you should periodically stop brushing your teeth to maintain dental health—it's based on misunderstanding, not science.

Long-term studies suggest  (16):

  • Generally no negative effects from continuous creatine use if taken as directed for up to five years (the longest studies conducted)
  • Likely no  evidence of the body reducing its natural creatine production when supplementing
  • Probably no diminishing returns or adaptations that would necessitate taking breaks

Creatine isn't a hormone that your body develops resistance to. It's more like vitamin D—something your body can make naturally but often benefits from consistent supplementation.

The Bottom Line

Creatine monohydrate stands as perhaps the most researched supplement in sports nutrition history, with over 1,000 studies confirming its safety and effectiveness for both men and women. It's like the reliable family sedan in a marketplace full of exotic, untested sports cars—not as flashy as newer supplements, but backed by decades of reliable performance data.

Remember that while supplements can help, they don't replace proper nutrition, consistent exercise, hydration, and adequate sleep. Think of creatine as a performance enhancer for an already well-maintained engine, not a fix for neglected maintenance.
