Paul Saladino MD:
Most people still think creatine is just for muscle gains in the gym...
But the data consistently shows creatine does SO much more than that.
This stuff is incredible.
And it's probably one of the most well-studied, safest, cheapest supplements you can take.
So today I'm breaking down 7 benefits of creatine you may not know about yet…
Let's get into it!
#1 Makes You Smarter
Ok, some of you have probably heard this one by now… but it’s still fascinating to me.
A massive systematic review analyzed 16 randomized controlled trials and found that creatine supplementation significantly improves memory, attention, and processing speed (PMID: 39070254).
The effects may be even more pronounced in older adults (PMID: 35984306).
Why does this happen?
Your brain runs on ATP - energy currency for your cells.
Creatine stores phosphate groups in your brain that quickly regenerate ATP when your brain needs it.
More ATP = better brain function.
I talked about this in my creatine video, but at higher doses - like 20 grams per day - creatine can actually cross the blood-brain barrier and increase brain creatine stores too.
That's when you see the BIGGEST cognitive benefits… especially if you're sleep deprived, stressed, or doing cognitively demanding tasks.
So if you want a sharper brain... creatine is a no-brainer (pun intended!).
#2 Women may need Creatine even MORE than men
Most men have heard of creatine - we've seen it in bodybuilding magazines, heard gym bros talk about it.
But turns out… Women have 70-80% LOWER creatine stores than men (PMID: 33800439).
And the research shows creatine is absolutely CRITICAL for female health across the entire lifespan.
In a study of 4,522 US women, those eating higher amounts of creatine from food had 25% lower odds of irregular periods and significantly lower risks of fetal macrosomia, pelvic infections, hysterectomy, and needing HRT (PMID: 39055234).
During pregnancy, creatine is vital too…
Your reproductive tissues, placenta, and developing fetus rely heavily on the creatine-phosphocreatine energy system (PMID: 33540766).
Preclinical models even suggest maternal creatine supplementation can protect the fetus from hypoxic injury - when the baby isn't getting enough oxygen.
And in peri/postmenopausal women, creatine improves sleep quality and supports bone health when combined with resistance training.
#3 Makes S***m Stronger
Low semen creatine is associated with poor s***m count and motility. But when men supplement with creatine, pilot trials show improved s***m quality.
Research shows that higher semen creatine levels are directly linked to better s***m motility - meaning your s***m swim better and have more energy (PMID: 32902220).
Creatine provides energy to s***m cells through the same phosphocreatine system we talked about earlier.
More creatine = more ATP = stronger, faster s***m.
And a comprehensive review concluded that creatine should be considered a key component of a paternal preconception diet (PMID: 35276945).
So if you're planning to have kids, adding creatine to your diet is a smart move.
#4 Neurological + Psychiatric Disorders
This is where creatine really shows its therapeutic potential…
A comprehensive clinical review found that creatine has benefits for a LONG list of brain-related conditions (PMID: 33578876):
Traumatic brain injury (TBI)
Concussions
Depression
Anxiety
Brain energy shortage diseases
Sleep deprivation
Hypoxia
All of these conditions involve problems with brain energy metabolism.
Your brain isn't making enough ATP to function properly .And Creatine can help support that.
Another review specifically highlighted creatine's role in TBI, neurodegeneration, depression, anxiety, and cognitive decline (PMID: 35267907).
So if you or someone you know is dealing with any of these conditions, creatine supplementation might be worth exploring.
Especially since it's so safe and affordable.
#5 Metabolic & Cardiovascular Health Benefits
Creatine isn't just for athletes…
It has real therapeutic benefits for people with metabolic and cardiovascular conditions.
Research shows creatine helps with statin myopathy, muscular dystrophy, and certain cardiovascular-related markers such as homocysteine (PMID: 31533334, PMID: 17253521, PMID: 25853877).
#6 Potential Chronic Pain Support
This one surprised me!
Creatine has been studied in pain-related conditions such as fibromyalgia, where it improves muscle energy availability and strength, with pain outcomes remaining stable or improved (PMID: 23554283).
Makes sense when you think about it...
Chronic pain conditions are often associated with impaired muscle energy metabolism and reduced cellular energy availability.
Not suggesting creatine is a cure…
But if you're dealing with chronic joint pain, muscle pain, or fatigue, adding creatine to your regimen might help.
#7 Healthy Aging & Sarcopenia
I talked about this recently…
But Sarcopenia is a MAJOR problem in aging humans.
Creatine has strong evidence for putting the brakes on muscular atrophy and sarcopenia in elderly populations (PMID: 24576864).
If you have aging parents or grandparents get them on creatine NOW. Especially if they have osteopenia (low bone density).
