However, there\u2019s evidence that many of us could stand to consume more.

In a word: no. <\/p>\n<p>\u201cThis is actually one of the most common myths surrounding creatine, as research shows that creatine doesn\u2019t cause dehydration,\u201d he tells Fit&amp;Well. \u201cCreatine works by drawing water into your muscle cells, not pulling it away from other tissues.\u201d <\/p>\n<p>While studies examining heat tolerance, cramping and hydration markers found no increased dehydration risk with creatine use, O\u2019Leary adds that because creatine increases intracellular water retention, some people initially feel they need more water.<\/p>\n<p>\u201cThink of your muscles as sponges that are now holding more fluid,\u201d he explains. \u201cYour body simply needs adequate intake to maintain balance throughout all tissues.\u201d<\/p>\n<p>Topping up daily water intake by 500ml to a liter while supplementing with creatine can help accommodate this fluid shift into the muscles, he says, helping maintain optimal hydration. <\/p>\n<p>He also recommends monitoring urine color (pale yellow is ideal) and drinking consistently throughout the day, rather than chugging your daily quota of H2O at once. <\/p>\n<p><a id=\"elk-2-my-work-capacity-for-exercise-improved\"\/>2. My work capacity for exercise improved<\/p>\n<p id=\"80db78d4-62bb-494b-9635-9fd2bb81b7b2\">This month-long test coincided with training for and completing my first solo HYROX race, followed immediately by a frankly ludicrous challenge that involved doing 300 kettlebell swings a day for 30 days.<\/p>\n<p>While I am relatively active for a 38-year-old dad who\u2019s had to give up his usual morning workout for the nursery run, this was a meaty step up in training volume and intensity compared with how I usually exercise.<\/p>\n<p>Nevertheless, for the most part, my body was able to take this increased workload in its stride and I woke up feeling remarkably fresh despite the previous day\u2019s exertions.<\/p>\n<p>Creatine\u2019s potential to boost workout output has been widely accepted since <a data-analytics-id=\"inline-link\" href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/1327657\/\" target=\"_blank\" data-url=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/1327657\/\" referrerpolicy=\"no-referrer-when-downgrade\" data-hl-processed=\"none\" data-mrf-recirculation=\"inline-link\" rel=\"nofollow noopener\">a landmark Swedish study<\/a> back in 1992, which found daily supplementation boosted levels of phosphocreatine by approximately 20%.<\/p>\n<p>This high-energy molecule rapidly regenerates adenosine triphosphate (ATP), the main energy currency of every cell in the human body.<\/p>\n<p>More phosphocreatine means more energy for short-duration, high-intensity efforts, of the type I did to prepare for a HYROX race and swinging a heavy kettlebell between my legs.<\/p>\n<p>Does creatine make exercise feel easier? <\/p>\n<p>I asked O\u2019Leary if my improved work capacity could be attributed to upping my creatine intake and he said it checked out. <\/p>\n<p>\u201cThink of it like extending your muscles\u2019 battery life,\u201d he says. \u201cYour muscles store creatine phosphate, which rapidly regenerates ATP during intense efforts lasting 1-10 seconds. Supplementing increases these stores by 20-40%, meaning you can sustain maximal effort slightly longer before fatigue sets in.\u201d<\/p>\n<p>For average exercisers, O\u2019Leary says research suggests this translates to performing 1-2 more reps per set, a 5-15% improvement in high-intensity exercise capacity, recovering faster between sets and maintaining power output during repeated efforts. <\/p>\n<p>The net result of this increased work capacity is long-term physical adaptations, like improved strength and stamina. And it\u2019s just as effective for beginners and older adults alike. <\/p>\n<p>\u201cBeginners benefit because creatine helps them handle training volume better, potentially accelerating initial strength gains and adaptation,\u201d says O\u2019Leary. \u201cFor older adults (50-plus), creatine is particularly valuable as it combats age-related muscle loss (sarcopenia), supports cognitive function and may help maintain bone density.\u201d <\/p>\n<p>Beyond the gym, O\u2019Leary says many users report better performance in recreational sports, yard work or simply playing with their kids. <\/p>\n<p><a id=\"elk-3-i-felt-fresher-mentally\"\/>3. I felt fresher mentally<\/p>\n<p id=\"23ce5354-c4af-4bf1-a49e-a6588feb8f91\">I woke up feeling more mentally switched on, as well as physically fresher.<\/p>\n<p>This was something I didn\u2019t expect to notice. My increased training load meant I often had to exercise after work or after dinner, pushing my bedtime back, and back, and back.<\/p>\n<p>And yet, despite not getting anywhere near enough sleep, I rarely felt mentally fatigued.<\/p>\n<p>I was able to juggle an unholy number of tasks, including executing the mental gymnastics required to file my tax return on time.<\/p>\n<p>I shouldn\u2019t have been quite so surprised. A <a data-analytics-id=\"inline-link\" href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/14561278\/\" target=\"_blank\" data-url=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/14561278\/\" referrerpolicy=\"no-referrer-when-downgrade\" data-hl-processed=\"none\" data-mrf-recirculation=\"inline-link\" rel=\"nofollow noopener\">human trial in 2003<\/a> was the first to show that oral creatine supplementation can improve cognitive performance, not just muscle function.<\/p>\n<p>Can creatine boost brainpower? <\/p>\n<p>Certainly. O\u2019Leary says creatine acts in the brain much like it does in the muscles. \u201cYour brain, like muscles, uses ATP for function,\u201d he explains. <\/p>\n<p>Research shows promising improvements in working memory, processing speed and mental fatigue resistance, especially during stressful conditions like sleep deprivation, mental exhaustion or demanding cognitive tasks.<\/p>\n<p>\u201cThink of it as helping your brain\u2019s power grid stay stable when demand is high,\u201d he elaborates. Studies suggest the benefits are most pronounced with vegetarians, whose baseline creatine levels are lower, and older adults. <\/p>\n<p>\u201cEffects appear modest but meaningful, typically around 5-10% improvements in cognitive testing under challenging conditions,\u201d he says, adding that while the evidence is encouraging and growing, we need more large-scale studies to fully establish these effects. <\/p>\n<p>That said, O\u2019Leary stresses that creatine supplementation should not replace getting enough good-quality sleep. <\/p>\n<p>\u201cIt\u2019s quite plausible that creatine contributed to your resilience,\u201d he says. \u201cSleep deprivation depletes brain energy reserves and intense training adds physical stress. Creatine helps buffer against both.\u201d <\/p>\n<p>My scenario of combined physical and mental stress is exactly where creatine\u2019s neuroprotective effects may become noticeable. <\/p>\n<p>However, he says, this research area is still emerging and individual responses vary. <\/p>\n<p>\u201cWhile creatine played a supportive role in maintaining your mental clarity, it\u2019s not a magic solution or sleep replacement. Proper rest remains essential for optimal recovery. Consider creatine as one helpful factor among several, rather than the sole explanation for your experience.\u201d <\/p>\n<p id=\"d53630e9-12ce-4661-81b0-e4dca53a2e4c\">Browse <a data-analytics-id=\"inline-link\" href=\"https:\/\/target.georiot.com\/Proxy.ashx?tsid=110083&amp;GR_URL=https%3A%2F%2Famazon.com%2FCreatine-Nutritional-Supplements%2Fb%2Fref%3Ddp_bc_4%3Fie%3DUTF8%26node%3D3773431%26tag%3Dhawk-future-20%26ascsubtag%3Dfitandwell-gb-4378424908563785632-20\" target=\"_blank\" data-url=\"https:\/\/www.amazon.com\/Creatine-Nutritional-Supplements\/b\/ref=dp_bc_4?ie=UTF8&amp;node=3773431\" referrerpolicy=\"no-referrer-when-downgrade\" rel=\"sponsored noopener nofollow\" data-hl-processed=\"hawklinks\" data-google-interstitial=\"false\" data-placeholder-url=\"https:\/\/target.georiot.com\/Proxy.ashx?tsid=110083&amp;GR_URL=https%3A%2F%2Famazon.com%2FCreatine-Nutritional-Supplements%2Fb%2Fref%3Ddp_bc_4%3Fie%3DUTF8%26node%3D3773431%26tag%3Dhawk-future-20%26ascsubtag%3Dhawk-custom-tracking-20\" data-merchant-name=\"Amazon US\" data-merchant-id=\"1471\" data-merchant-network=\"Amazonus\" data-merchant-url=\"amazon.com\" data-mrf-recirculation=\"inline-link\">creatine supplements on Amazon<\/a><\/p>\n<p>About our expertAbout our expertMike O\u2019Leary<\/p>\n<p>Social Links Navigation<\/p>\n<p><a class=\"button-social   \" href=\"https:\/\/www.linkedin.com\/in\/olearymike1\/?originalSubdomain=pl\" target=\"_blank\" aria-label=\"LINKEDIN\" rel=\"nofollow noopener\"><\/a><\/p>\n<p>Mike O\u2019Leary Ph.D is a specialist in medical research and sports supplements product development and head of product at German sports nutrition company <a href=\"https:\/\/uk.esn.com\/\" rel=\"nofollow noopener\" target=\"_blank\">ESN<\/a>.
