Key Highlights

• A 12-week randomized trial of 64 adults (45–65) found 10 g/day creatine produced measurable increases in lean tissue and strength even among participants who did not follow a structured exercise program.
• When combined with a modest calorie-deficit diet and an aerobic plus resistance training program, creatine supplementation amplified lean-mass gains and reduced fat mass compared with diet and exercise alone.
• Creatine’s effects extend beyond performance: mechanistic pathways and prior research indicate potential benefits for brain health, energy metabolism, and preserving muscle during weight loss, but safety and dosing should be considered case-by-case.

Introduction

Creatine is everywhere in wellness feeds: marketed to athletes, recommended for aging adults, and sold in powders, pills, and energy bars. Researchers have long documented creatine’s ability to improve short-term high-intensity performance and increase muscle mass when paired with resistance training. New data from a 12-week trial of middle-aged adults adds a surprising wrinkle: creatine supplementation produced gains in lean tissue and strength even among participants who did not follow a structured exercise routine.

The implications matter for a broad group—people aiming to preserve muscle mass as they age, those trying to lose fat without losing muscle, and individuals who lack the time or ability to adhere to a gym program. This report examines the study’s design and findings, places them in the context of existing science, explains how creatine works, and provides practical guidance on dosing, safety, and unanswered questions researchers need to resolve.

What creatine is and how it supports muscle and energy

Creatine is a naturally occurring compound synthesized from three amino acids: arginine, glycine, and methionine. The body produces about 1–2 grams per day, and dietary sources—particularly red meat, fish, and some dairy—supply additional amounts. Roughly 95 percent of the body’s creatine is stored in skeletal muscle; the remainder resides in the brain, heart, and other tissues.

At the cellular level, creatine forms phosphocreatine, a high-energy reserve used to regenerate adenosine triphosphate (ATP) during short bursts of high-intensity activity. When muscles demand immediate energy, phosphocreatine donates a phosphate group to ADP to make ATP, enabling brief, intense efforts such as sprinting, lifting, or rising from a chair. Replenishing phosphocreatine stores supports repeated high-intensity efforts, improves work capacity during resistance training, and reduces perceived fatigue.

Beyond this primary bioenergetic role, creatine influences several processes linked to muscle mass:

• Increased intracellular water retention, which can create a stronger anabolic signal for muscle protein synthesis.
• Enhanced satellite cell activity and signaling pathways that participate in muscle repair and growth.
• Improved recovery from exercise, enabling greater training volume over time.
• Potentially reduced inflammation and protection of mitochondrial function.

These mechanisms help explain why creatine is effective when combined with resistance training. The recent trial suggests that some of these effects may also operate independently of structured exercise, at least over a 12-week window, producing modest but measurable improvements in lean tissue and strength.

The Texas A&M study: design, participants, and interventions

Researchers followed 64 healthy adults aged 45 to 65 over a 12-week period. The study design allowed participants to self-select whether they would enroll in a structured exercise-and-diet program or refrain from a formal exercise regimen, then randomly assigned them to either creatine supplementation (10 grams daily) or a placebo.

Key design elements:

• Age range: 45–65 years, focusing on middle-aged adults at an inflection point for muscle mass decline.
• Duration: 12 weeks—long enough to capture short-term changes in muscle mass, strength, and body composition but not intended as a measure of long-term safety or durability.
• Supplement dose: 10 grams per day of creatine. This dose is higher than the commonly recommended maintenance dose of 3–5 grams per day but lower than aggressive loading regimens.
• Groups:
  • Exercise + creatine: participants completed an aerobic and resistance training plan and followed a mild calorie-deficit diet for weight-loss subgroups.
  • Exercise + placebo: same exercise and diet but placebo instead of creatine.
  • No-exercise + creatine: participants did not follow a structured exercise program but took creatine.
  • No-exercise + placebo: no structured exercise and placebo.
• Outcome measures: changes in lean tissue (often measured by DXA or similar-level imaging), bench press and leg press maximums, fat mass, and self-reported energy levels. The publication also reported cognitive-function and standard markers of health, though muscle and composition outcomes were central.

This mixed design—allowing participants to pick exercise status while randomizing supplement assignment—produced two important contrasts: the effect of creatine with exercise versus placebo, and the effect of creatine without exercise versus placebo in people who did not adopt a formal training plan.

What the trial found: gains in lean tissue and strength, and improved fat loss with diet and exercise

The trial produced several notable outcomes.

Lean tissue and strength in the non-exercise group:

• Participants in the “no exercise” group who took 10 grams of creatine daily gained approximately 2.4 pounds (about 1.1 kilograms) of lean tissue over 12 weeks.
• Bench press and leg press strength improved in these participants despite the absence of a structured exercise program.

Creatine plus diet-and-exercise:

• Participants who combined a mild calorie-deficit diet and a structured aerobic/resistance training program with creatine supplementation saw nearly 3 pounds of lean tissue gain and a reduction in fat mass.
• The exercise-plus-placebo group, which followed the same diet and training program but took placebo, experienced minimal change in lean tissue.
• Study authors noted this may represent one of the first controlled demonstrations that adding creatine to a diet-and-exercise weight-loss program yields greater fat loss than diet and exercise alone.

Energy and subjective outcomes:

• Participants in the exercise-and-creatine group reported sustained energy—for exercise sessions and daily life—relative to placebo.

Safety signals:

• The study did not report emergent safety concerns in the short-term timeframe for healthy middle-aged adults. However, the paper reiterated the need for caution among people with kidney or liver disease, women who are pregnant or breastfeeding, and those with certain mental health disorders, given limited data in those populations.

The combination of direct improvements in strength and measurable increases in lean tissue—without structured exercise—raises questions about the minimal activity or daily functional tasks that, with creatine, may be enough to trigger hypertrophic mechanisms in middle-aged bodies.

How might creatine increase muscle and strength without formal exercise?

Researchers propose several plausible mechanisms by which creatine supplementation could increase lean mass and strength absent a structured exercise program. These are not mutually exclusive.

1. Enhanced day-to-day functional capacity Small, routine physical actions—walking, carrying groceries, climbing stairs—impose micro-stresses on muscle. Creatine’s role in rapid ATP regeneration can improve performance in brief, everyday efforts and allow slightly greater intensity or volume during those routine tasks. Repeatedly performing ordinary movements with marginally higher force can tilt the balance toward increased muscle protein synthesis over weeks.
2. Cellular hydration and anabolic signaling Creatine draws water into muscle cells, increasing intracellular volume. Cell swelling acts as an anabolic stimulus, activating signaling pathways associated with protein synthesis and inhibiting pathways that promote protein breakdown. This volumization effect can occur independently of large training stimuli.
3. Satellite-cell activation and muscle repair Creatine may sensitize satellite cells (muscle stem cells) to low-level mechanical cues, improving repair and growth responses to minor muscle damage. Even light activity produces microdamage that would otherwise be insufficient to prompt growth; creatine could amplify the repair response.
4. Reduced muscle protein breakdown during mild calorie deficits In weight-loss contexts, creatine appears to favor retention of lean mass. The trial’s exercise-and-creatine subgroup lost fat while gaining lean tissue, suggesting creatine helps preserve or increase contractile tissue despite a caloric shortfall.
5. Neuromuscular function and motor-unit recruitment Improvements in neuromuscular efficiency and motor-unit recruitment could underlie strength gains absent large changes in muscle cross-sectional area. Creatine’s effects on the brain and central nervous system—through increased brain creatine—could also contribute to improved coordination or reduced perception of effort.

The cumulative effect of these mechanisms may explain modest lean-mass increases and strength gains in people not undertaking formal training. The study did not claim creatine can replace exercise; rather, it showed measurable benefit independent of a structured program.

How this study fits into broader evidence on creatine for aging and non-athletic health

A growing literature examines creatine beyond athletic performance. Trials and meta-analyses have explored creatine in older adults, clinical populations, and cognitive outcomes:

• Older adults and sarcopenia: Multiple trials find creatine augments the benefits of resistance training in older adults, enhancing gains in muscle mass and function. Some evidence suggests creatine may help counteract age-related sarcopenia when combined with physical activity, and it has potential as an adjunct when exercise is limited.
• Weight loss and body composition: Studies indicate creatine may help preserve lean mass during calorie restriction. The Texas A&M trial contributes novel controlled evidence that creatine can amplify fat loss while increasing lean tissue when combined with diet and exercise.
• Cognitive function: Preliminary research links creatine supplementation with improvements in certain cognitive tasks, particularly in sleep-deprived individuals or those with suboptimal dietary creatine (e.g., strict vegetarians). Creatine’s presence in the brain supports energy-demanding processes associated with memory and executive function.
• Clinical conditions: Investigations into creatine for neuromuscular diseases, depression, and mitochondrial disorders have produced mixed results. Some trials show symptomatic improvement in specific conditions; others show minimal benefit. Safety and efficacy remain condition-specific and require clinical oversight.

Collectively, these studies position creatine as a low-cost supplement with multiple potential applications. The Texas A&M results extend applicability into middle age and suggest effects when formal exercise is absent—though larger and longer-term trials are needed.

Dosing, timing, and formulations: what the evidence supports

Clinical and practical dosing regimens for creatine vary. The Texas A&M study used 10 grams per day, which differs from typical recommendations. Practical points:

• Common dosing strategies:
  • Loading phase: 20 grams per day (divided into 4 doses of 5 grams) for 5–7 days, followed by maintenance.
  • Maintenance dose: 3–5 grams per day.
  • Alternate approach: Skip the loading phase and use 3–5 grams per day; muscle creatine stores will reach saturation within 3–4 weeks.
• Study dose: 10 grams/day is higher than standard maintenance dosing and lower than traditional loading protocols. Short-term tolerability was acceptable in the trial, but clinicians may prefer established maintenance doses for long-term use.
• Timing: Creatine can be taken any time of day. When paired with a carbohydrate or carbohydrate-plus-protein meal, creatine uptake appears slightly improved due to insulin-mediated transport. Post-exercise ingestion is common in studies because it may align with nutrient-sensing and recovery windows, but timing differences are modest.
• Formulations: Creatine monohydrate is the most extensively studied formulation and remains the gold standard for efficacy and cost. Other forms—creatine hydrochloride, buffered creatine, creatine ethyl ester—claim benefits but lack robust evidence of superiority.
• Dosage for older adults: Many clinical trials with older participants use a maintenance dose of 3–5 grams/day, often combined with resistance exercise. Higher doses can be used short-term but require monitoring if used long-term.

For people considering supplementation, aligning dose with intent matters. The Texas A&M trial’s 10-gram dose demonstrated efficacy over 12 weeks in middle-aged adults; whether lower daily doses would produce identical results in the same timeframe is plausible but unproven in that cohort.

Safety profile and populations requiring caution

Safety is central to clinical decision-making. Large numbers of studies in healthy adults show creatine is well tolerated at recommended doses for months to years, with side effects typically mild. Key points:

• Common side effects: transient gastrointestinal discomfort at high single doses, modest weight gain due to intracellular water retention, occasional bloating.
• Kidney and liver disease: Persons with preexisting kidney or liver impairments were excluded from many trials. Limited evidence leaves uncertainty on safety in these populations; clinicians commonly recommend against unsupervised use in people with renal impairment or to monitor renal function if used therapeutically.
• Pregnancy and breastfeeding: Insufficient data exist to establish safety. Avoid supplementation during pregnancy and lactation unless under direct clinical supervision.
• Children and adolescents: Creatine is used in adolescent athletes in some studies, but dosing and supervision require pediatric input. Most guidelines prioritize conservative use and thorough evaluation.
• Drug interactions: Theoretical interactions exist with nephrotoxic medications (e.g., some nonsteroidal anti-inflammatory drugs, certain antibiotics) and diuretics, which could affect hydration and renal function. Clinicians should assess concurrent medications.
• Long-term safety: Trials extending for multiple years report no consistent adverse findings in healthy adults, but lifelong safety evidence is incomplete.
• Product quality: Supplements are regulated as dietary supplements in many countries, which means quality and purity vary. Contaminants and inaccurate labeling are real risks.

Before initiating creatine, people should consult their healthcare provider if they have chronic disease, are taking medications with renal implications, or are pregnant or breastfeeding. For healthy adults, creatine monohydrate at standard maintenance doses carries a strong safety record when combined with routine hydration and periodic monitoring.

Who stands to benefit most—and who might see limited returns

Beneficial populations:

• Middle-aged and older adults aiming to preserve or increase muscle mass, particularly when combined with resistance training.
• People attempting weight loss who want to minimize muscle loss while reducing fat mass.
• Vegetarians and vegans, who typically consume less dietary creatine and may show a more pronounced response to supplementation.
• Individuals with limited exercise capacity—those recovering from injury or with mobility constraints—who could derive modest functional benefits.

Populations with uncertain benefit or higher risk:

• People with advanced chronic kidney disease, liver disease, or uncontrolled comorbidities should avoid unsupervised use.
• Pregnant and breastfeeding women due to insufficient safety data.
• Individuals seeking large, rapid changes in lean mass without exercise. Creatine supports muscle-building processes but does not substitute for progressive resistance training in producing substantial hypertrophy.

Clinical decision-making should incorporate baseline diet, activity level, medication use, and renal function.

Practical guidance: choosing a creatine product and using it safely

Selecting a supplement and integrating it into daily life requires cautious pragmatism:

Product selection:

• Prefer creatine monohydrate. It is inexpensive, well-studied, and effective.
• Look for third-party testing seals (e.g., NSF Certified for Sport, USP). These reduce the risk of contaminants and verify contents.
• Avoid proprietary blends that hide exact creatine amounts or include stimulant complexes with unclear safety profiles.

Dosing plan options:

• Conservative route: 3–5 grams per day without loading. This saturates muscle stores over several weeks with minimal GI upset.
• Loading route: 20 grams spread across the day for 5–7 days, then maintain at 3–5 grams/day. Loading achieves saturation faster but raises the chance of transient GI symptoms.
• The study used 10 grams/day; using this dose in clinical practice requires weighing potential benefits and tolerability.

Administration tips:

• Mix powder with water or a carbohydrate-containing beverage for improved uptake.
• Split large daily doses to reduce GI discomfort.
• Maintain adequate hydration; creatine shifts intracellular water and may change water requirements.
• Pair supplementation with resistance exercise where feasible to amplify effects.

Monitoring and follow-up:

• Check baseline renal function (serum creatinine, estimated glomerular filtration rate) where clinical history suggests risk.
• Re-evaluate renal function periodically if long-term supplementation is intended or if the individual has risk factors for renal dysfunction.
• Stop supplementation and consult a clinician if severe adverse symptoms occur.

Cost considerations:

• Most high-quality creatine monohydrate powders are inexpensive relative to other supplements, making them accessible for many people seeking pragmatic gains in muscle and function.

Limitations of the recent trial and directions for future research

The Texas A&M trial adds valuable evidence but possesses limitations that constrain broad generalization.

Sample size and duration:

• Sixty-four participants provide signal but not definitive evidence. A larger sample size would increase power to detect subgroup effects and rare adverse events.
• Twelve weeks captures short-term changes but cannot establish long-term safety or the durability of effects beyond three months.

Participant selection and exercise self-selection:

• Allowing participants to choose whether to adopt a formal exercise regimen introduces potential self-selection bias. Those who elect to exercise may differ in motivation, baseline fitness, or lifestyle in ways that influence outcomes.
• Randomized trials that assign exercise status would produce stronger causal inference about interactions between exercise and supplementation.

Dose-response uncertainty:

• The study used 10 grams/day. Whether lower maintenance doses (3–5 g/day) would produce comparable results in middle-aged non-exercisers remains to be tested.

Measurement techniques and functional outcomes:

• Details on body composition methods (e.g., DXA, bioelectrical impedance) and their sensitivity to changes in intracellular water versus true contractile tissue matter. Distinguishing between water-mediated weight gain and true increases in muscle protein is critical.
• Functional outcomes beyond bench and leg press—such as gait speed, balance, chair-stand tests, and activities-of-daily-living metrics—would clarify real-world benefit.

Population diversity:

• The study focused on healthy middle-aged adults. Trials in older adults over age 65, populations with chronic disease, and more diverse ethnic and socioeconomic groups would enhance external validity.

Mechanistic markers:

• Correlating muscle creatine content, satellite cell activation markers, inflammatory cytokines, and mitochondrial function with clinical outcomes would illuminate the pathways of benefit.

Future trials should prioritize randomized assignment to exercise conditions, longer follow-up, larger sample sizes, and expanded functional endpoints.

Real-world examples: how creatine is being used outside the lab

Athletes and performance enthusiasts have used creatine for decades; guidelines from sports medicine authorities endorse it for short-duration, high-intensity sports. Outside elite sport, several patterns have emerged:

• Older adults in community programs: Community-based resistance-training classes sometimes pair supervised creatine supplementation with exercise regimens. Clinicians and exercise physiologists report improved class adherence and strength gains in these participants compared with exercise alone.
• Weight-loss programs: Some medically supervised weight-management clinics incorporate creatine to reduce lean-mass loss during caloric restriction, monitoring renal function and adjusting doses.
• Vegetarians and vegans: Because dietary creatine is low in plant-based diets, a subset of vegetarians reports noticeable increases in performance and subjective recovery after starting 3–5 grams/day.
• Clinical rehabilitation: In rehabilitation settings—post-orthopedic surgery or during outpatient physical therapy—creatine has been used experimentally to accelerate recovery of strength, though protocols vary and evidence remains mixed.

Anecdotal reports vary widely; controlled clinical trials remain the gold standard for assessing efficacy. Still, real-world adoption often mirrors the compound’s safety profile and low cost, making it a common adjunct to rehabilitation and maintenance programs.

Common misconceptions and clarifications

Several persistent myths surround creatine. Clarifying these helps contextualize the new findings.

Myth: Creatine is an anabolic steroid.

• Fact: Creatine is a naturally occurring compound. It is not a steroid, does not affect testosterone production directly, and is legal and widely used in sport.

Myth: Creatine causes irreversible kidney damage in healthy people.

• Fact: In healthy adults, standard creatine doses have not been linked to progressive kidney damage in randomized trials and observational studies. People with preexisting renal disease should avoid unsupervised supplementation.

Myth: Creatine makes you bulky and bloated permanently.

• Fact: Initial weight gain often reflects intracellular water retention and is transient for many. Longer-term increases that reflect true muscle mass require time and stimuli such as resistance exercise. Not everyone experiences bloating.

Myth: Creatine only helps bodybuilders and athletes.

• Fact: Evidence supports benefits for older adults, people losing weight, and those with low dietary creatine intake. Cognitive and mitochondrial benefits are under active investigation.

Addressing misconceptions helps set realistic expectations for potential users and reinforces the need for individualized clinical judgment.

Regulatory landscape and product quality

Supplements fall under dietary supplement regulations in many jurisdictions, which emphasizes post-market monitoring over pre-market approval. This creates variability in product purity and label accuracy.

Key points for consumers and clinicians:

• Third-party testing is critical. Look for NSF Certified for Sport, USP, or Informed-Sport seals to reduce contamination risk.
• Avoid products making improbable claims (e.g., “miracle overnight muscle”) or combining creatine with high doses of stimulants and undeclared substances.
• Keep receipts and batches in case manufacturers issue recalls.

Clinicians prescribing or recommending creatine should consider product sourcing and advise patients to select reputable brands verified by third-party testing.

Practical decision framework for clinicians and consumers

When deciding whether to use creatine, apply a straightforward decision framework:

1. Assess baseline health
   • Review kidney and liver function, medications, pregnancy status, and chronic disease.
2. Define the goal
   • Preserve lean mass during weight loss, augment resistance-training gains, improve short-term power, or explore cognitive support.
3. Select dose and product
   • Prefer creatine monohydrate from a third-party tested brand.
   • Start with 3–5 g/day for most people; consider alternative dosing only with clinical oversight.
4. Monitor and reassess
   • Reassess strength and body composition after 8–12 weeks.
   • Repeat basic renal panel if long-term use or if risk factors are present.
5. Combine with pragmatic activity
   • Encourage resistance training when feasible; even light activity increases the likelihood of meaningful functional gains.

This framework balances potential benefits with safety considerations and aligns with evidence-based practice.

What researchers need to study next

The trial prompts targeted research questions:

• Do lower maintenance doses (3–5 g/day) replicate the 10 g/day findings in middle-aged non-exercisers?
• What are the long-term safety and efficacy profiles beyond 12 weeks in middle-aged and older adults?
• Can creatine supplementation reduce clinically meaningful endpoints—falls, fracture risk, disability—over multi-year trials?
• How do creatine’s effects vary by baseline diet, sex, ethnicity, and genetic polymorphisms related to creatine transport and metabolism?
• Which biomarkers best distinguish increases in contractile tissue from fluid-mediated changes in lean mass?
• Does creatine have disease-modifying effects in neurodegenerative disorders or metabolic diseases when combined with other interventions?

Targeted studies will clarify clinical utility, optimal dosing, and long-term safety across diverse populations.

FAQ

Q: Is creatine safe for someone my age (45–65) with no major medical problems? A: For healthy middle-aged adults, creatine monohydrate at common maintenance doses (3–5 g/day) has an established safety record in clinical trials. The Texas A&M study used 10 g/day for 12 weeks without immediate safety concerns. Still, baseline renal and liver assessments and a discussion with a healthcare provider are prudent before starting supplementation.

Q: Will creatine make me gain fat? A: Creatine does not cause fat gain. Short-term weight increases often reflect intracellular water retention. When combined with a calorie-deficit diet and exercise, creatine in the cited study enhanced fat loss while increasing lean tissue.

Q: Do I have to lift weights to benefit from creatine? A: No. The recent study showed lean-mass and strength gains in participants who did not follow a structured exercise program. That said, resistance training reliably amplifies creatine’s effects on muscle size and function and remains the most potent way to increase and preserve muscle mass.

Q: How much creatine should I take? A: Common regimens include a loading phase (20 g/day split for 5–7 days) followed by maintenance (3–5 g/day), or simply 3–5 g/day without loading. The new trial used 10 g/day. For most people, a conservative 3–5 g/day approach balances efficacy and tolerability.

Q: Which form of creatine is best? A: Creatine monohydrate is the best-supported form in the scientific literature. It is effective, affordable, and well tolerated. Other formulations lack robust evidence of superiority.

Q: Will creatine harm my kidneys? A: Healthy adults typically do not experience renal harm from recommended creatine doses in clinical trials. People with preexisting kidney disease or those taking nephrotoxic medications should avoid unsupervised supplementation and consult a clinician.

Q: Can women take creatine? A: Yes. Women benefit from creatine similarly to men. Pregnant and breastfeeding women should avoid supplementation unless under direct medical supervision because safety data are limited.

Q: If I’m vegetarian, will I benefit more from creatine? A: Vegetarians often have lower baseline muscle creatine stores then omnivores and tend to show a larger relative response to supplementation in performance and possibly body composition.

Q: Does creatine help the brain? A: Emerging evidence suggests creatine can support cognitive performance in specific contexts—sleep deprivation, high-demand cognitive tasks, and in those with low baseline dietary creatine. Larger trials are needed to define clinical applications for cognitive health.

Q: How quickly will I notice changes? A: Some people report improved short-term power or reduced perceived effort within days. Measurable changes in strength or lean mass typically appear within several weeks; the Texas A&M trial reported changes by 12 weeks.

Q: Should I cycle creatine or take it continuously? A: Continuous daily maintenance dosing is common and supported by many trials. Cycling is not required but some people prefer periodic breaks. Long-term continuous use in healthy adults has been well-tolerated in many studies.

Q: Can creatine interact with medications? A: Potential interactions include drugs that affect renal function or hydration (diuretics, certain antibiotics, NSAIDs). Review medications with a clinician before beginning supplementation.

Q: Where should I buy creatine? A: Select reputable brands with third-party testing seals (NSF Certified for Sport, USP, or Informed-Sport). Avoid mixtures with proprietary blends of unknown quantities or stimulants.

Q: Does timing of creatine matter? A: Timing effects are modest. Taking creatine with a meal, post-workout, or with a carbohydrate-containing beverage may slightly improve uptake, but consistent daily dosing is most important.

Q: Will creatine replace the need for exercise? A: No. Creatine can augment the benefits of physical activity and may provide modest improvements without exercise, but it does not substitute for the broad systemic benefits of regular aerobic and resistance training.

Q: How should older adults incorporate creatine into a health plan? A: Older adults can consider creatine alongside progressive resistance training to preserve muscle mass and function. Clinicians should evaluate renal function, discuss dosing, and monitor progress with functional tests (e.g., chair-stand, gait speed) and periodic laboratory checks when indicated.

Q: What unresolved questions should patients watch for? A: Large randomized trials with longer follow-up, clearer data in people with chronic disease, and more precise dosing comparisons will refine recommendations. Monitoring ongoing research will help patients make informed decisions with their clinicians.

The recent trial extends the evidence base for creatine, highlighting measurable lean-mass and strength gains in middle-aged adults taking 10 g/day for 12 weeks—even among those who did not follow a formal exercise program. Those combining creatine with a mild calorie deficit and structured aerobic/resistance training achieved the most favorable body-composition changes, including reduced fat mass and increased lean tissue. For clinicians and adults interested in pragmatic methods to preserve strength and function with age, creatine monohydrate remains a low-cost, well-studied option, provided individual health status, dosing, and product quality are carefully considered.
