Creatine supplementation combined with resistance training increases muscle mass and strength in older adults by 5–10% more than resistance training alone, and emerging evidence suggests cognitive benefits — particularly for memory — in older adults.
Creatine monohydrate is the most evidence-supported sports supplement, with over 500 peer-reviewed studies. In older adults, creatine supplementation combined with resistance training increases lean mass by 1.37 kg and upper body strength by 7.5% more than resistance training alone. A 2023 meta-analysis found that creatine supplementation significantly improved memory in adults over 66.
Candow et al. (2008) in Medicine & Science in Sports & Exercise conducted a systematic review of creatine supplementation in older adults and found that creatine combined with resistance training produced significantly greater gains in lean mass, strength, and functional performance than resistance training alone. Rawson & Venezia (2011) in Amino Acids reviewed the evidence for creatine in older adults, concluding that it is safe and effective for improving muscle mass and strength. Prokopidis et al. (2023) in Nutrition Reviews conducted a meta-analysis of 8 RCTs and found that creatine supplementation significantly improved memory performance in adults over 66, with an effect size of 0.52 — a moderate, clinically meaningful improvement.

The NIA identifies creatine as a supplement with evidence for improving muscle function in older adults and notes that it is being studied for its potential cognitive benefits. MedlinePlus notes that creatine is one of the most studied sports supplements and is generally considered safe at recommended doses. The International Society of Sports Nutrition considers creatine monohydrate the most effective ergogenic nutritional supplement available for increasing high-intensity exercise capacity and lean body mass.
Creatine monohydrate is the most evidence-supported and cost-effective form. The standard dose is 3–5g per day, which can be taken at any time. A loading phase (20g/day for 5–7 days) is not necessary for older adults and may cause gastrointestinal discomfort. Creatine is safe for long-term use in healthy adults with normal kidney function. It is particularly beneficial when combined with resistance training — it enhances the training stimulus by allowing greater training volume. Vegetarians and vegans have lower baseline creatine stores and may benefit most from supplementation.
Vitaei verdict
Creatine monohydrate is one of the most evidence-supported supplements for older adults, improving muscle mass, strength, and potentially memory. It is safe, inexpensive, and well-tolerated.
How Does Resistance Training Benefit Older Adults Beyond Muscle Mass?
Resistance training in older adults improves muscle mass, bone density, metabolic health, cognitive function, and reduces all-cause mortality by 21–34% — with benefits extending well beyond the musculoskeletal system.
What Causes Sarcopenia and How Can We Effectively Prevent It?
Sarcopenia, the age-related loss of muscle mass and function, is a multifactorial condition primarily driven by chronic disuse and anabolic resistance. Prevention largely centres on progressive resistance training and adequate protein intake, though the precise interplay of contributing factors remains an active area of research.
Can You Build and Maintain Muscle After 50? An Evidence-Based Guide
Building and maintaining muscle mass after 50 is not only possible but crucial for healthy ageing. This review explores the robust evidence supporting resistance training and adequate protein intake, clarifying what genuinely works and where common advice may oversimplify the physiological realities of sarcopenia.
