💪 Creatine for Strength, Recovery, and Cognitive Edge
TLDR: Protein remains the most important nutrition lever for muscle. Once you are hitting a solid daily protein target, creatine monohydrate is the cheapest, most proven add-on for muscle growth and a small boost for brain function. All it takes is 3-5g per day plus sufficient hydration. Expect a few extra reps, faster recovery, and modest cognitive benefits.
What creatine actually does
Your liver and kidneys make roughly a gram of creatine each day. Most of it lives in skeletal muscle as phosphocreatine, a quick-access battery. Adenosine Triphosphate (ATP) is your body’s energy currency and when it is spent, it turns into Adenosine Diphosphate (ADP), which is like a drained battery. Phosphocreatine donates some of its molecules to recharge ADP into ATP.
What happens in the gym
A 2024 systematic review of randomized trials in adults under 50 reported that adding creatine to resistance training produced strength gains of ~10lbs for upper body lifts and ~25lbs for lower body lifts compared with training alone over 4 to 12 weeks.
Creatine and your brain
Creatine also lives in neurons and supports ATP recycling during high demand. Brain levels can rise with supplementation, although the increase is smaller than in muscle.
The latest quantitative look at cognition pooled 16 randomized trials and found small but significant improvements in memory and faster attention and processing speed, with benefits more apparent in people under load or with medical conditions.
Memory: On average, people taking creatine remembered about 10-12% more than those on placebo. In practical terms, if a memory test asked you to recall 10 words, creatine users might remember one extra word.
Processing speed: Here the effect is bigger. People completed timed mental tasks noticeably faster, shaving off fractions of a second per response. It does not sound like much, but across dozens or hundreds of decisions (as in reaction-time or attention tasks), it adds up to feeling more alert and less sluggish, especially when sleep-deprived or mentally taxed.
When the brain is stressed, effects can be bigger. Studies in sleep-deprived participants show improved performance after creatine, including a recent experiment using a single high dose during a night without sleep. These protocols are exploratory and not everyday dosing, but they reinforce the idea that creatine helps most when energy demand spikes.
How to take it
Dose: 3-5g per day. If you want to see effects quicker, you can do 20g per day (can be split into multiple doses) for 5 to 7 days, then take 3-5g per day.
Timing: Take it any time of day. Consistency beats timing.
Form: Choose creatine monohydrate. It has the best evidence and the lowest cost. Newer salts have not shown better real-world results.
Quality: Look for third-party testing such as NSF Certified for Sport or Informed Choice.

The gummy controversy
Creatine is rock‑solid stable as a dry powder but far more fragile when cooked into candy. The heat of gummy manufacturing and the acidity of fruit flavors can convert creatine into creatinine, a metabolite with none of the performance benefits.
In early 2025, the independent lab SuppCo pulled 10 top‑selling creatine gummy brands from Amazon and found that 6 delivered less than 20% of the label claim, and 2 contained no detectable creatine at all. The only brands that passed used low‑temperature infusion, published certificates of analysis, and shipped with refrigerated warehousing during summer.
If gummies keep you consistent, choose a lab‑verified brand (Create or Legion) and store the jar below 80 °F so the creatine you paid for doesn’t quietly degrade in the pantry.
Hair and kidney concerns
The widely shared concern about hair loss rests on a single small 2009 study that has not been replicated. Broader reviews have not found convincing evidence that creatine increases DHT or causes hair loss.
Position stands and controlled trials up to several years do not show harm to kidney function in healthy people at studied doses, although serum creatinine can rise slightly because creatine converts to creatinine and that can confuse lab interpretation. People with diagnosed kidney disease should speak with their clinician before use.
Potential downsides
Creatine is well tolerated, but a minority of people report stomach discomfort or bloating, especially when taking large doses at once. Splitting doses usually solves the problem. “Water weight” from increased muscle hydration can add 1-2 kg on the scale in the first weeks, but it’s ultimately better for performance.
Hydration is critical
Creatine draws extra water into muscle cells, which is good for performance, but only if you hydrate enough. The National Academies list adequate intakes around 3.7L per day for men and 2.7L per day for women, from all beverages and foods. Active people and hot weather can push needs higher.
We recognize how hard it is to drink a lot of water, so here’s a rule of thumb: aim for pale yellow pee (think “lemonade, not apple juice”). In other words, drink more than just “an extra glass.” Treat hydration like part of your training plan
Specific populations
Vegetarians and vegans: Baseline creatine stores can be lower on plant-only diets, which may increase the upside of supplementation, although one large modern trial found no difference in cognitive response by diet.
Women: Women saturate muscle at the same rate as men and see equivalent strength gains. Unique female wins include better cellular hydration during the luteal phase and early evidence of bone-density support post-menopause.
Older adults: Creatine with resistance training helps preserve muscle and strength with age, and cognitive benefits may matter most when the goal is independence rather than vanity metrics.
Why you should care
Protein is your foundation for muscle, while creatine helps you use muscle better. If you lift 2-4x per week and want a low-cost, high-signal supplement, take 3-5g of creatine monohydrate daily and follow a real hydration plan. You will likely squeeze out extra reps, recover a bit faster, and build or retain more strength. On the brain side, expect small but meaningful improvements, especially when life throws you sleep debt or heavy stress.
Strength is a health metric, not a vanity metric. Stronger muscles mean better metabolic health, fewer falls, and more independence as you age. A little creatine each day helps you stack the deck in your favor over time.
