5 Reasons to Start Taking Creatine TodayBacked by 2025–2026 Research

A 2026 systematic review published in Nutrition Reviews examined creatine's effect on cognition in older adults and found that creatine supplementation may support memory and cognitive processing — particularly in tasks that demand high mental energy (Marshall et al., 2026, PMID 40971619).

The mechanism makes sense: your brain runs on ATP, and creatine helps replenish it. During periods of mental stress, fatigue, or aging-related decline, having more creatine on board keeps your neurons firing efficiently.

Bottom line: While larger clinical trials are still needed, early evidence suggests creatine is one of the few supplements with a plausible benefit for brain health in aging adults.

Muscle loss (sarcopenia) accelerates after age 50 and is one of the primary drivers of frailty, falls, and metabolic decline. Two major 2025 meta-analyses confirm that creatine combined with resistance training significantly increases lean muscle mass in older adults — with one showing a meaningful advantage over training alone in both upper- and lower-body strength.

This isn't just an athlete story. If you walk, carry groceries, or want to stay independent as you age, maintaining muscle matters.

One of the most comprehensive creatine safety reviews ever published came out in 2025 in Frontiers in Nutrition. Titled "Creatine supplementation is safe, beneficial throughout the lifespan, and should not be restricted," it reviewed data from populations ranging from infants to elderly individuals and concluded:

• No adverse effects on kidney or liver function at doses up to 30 g/day
• No association with disordered eating or performance-enhancing drug use in younger populations
• Safe for long-term use

For general health maintenance, leading researchers now recommend 3 g/day as a simple, low-risk daily dose.

Creatine research has historically over-represented men — but that's changing. A 2025 review specifically examining creatine and resistance training in older females found significant improvements in lean tissue mass and lower-extremity strength across 10 randomized controlled trials.

Women also tend to have lower baseline creatine stores than men (partly due to lower dietary intake of red meat), which means they may experience a proportionally larger response to supplementation.

A 2025 clinical review published in the Journal of the International Society of Sports Nutrition found that creatine, primarily when combined with exercise, improves:

• Lean body mass
• Regional muscle size and strength
• Bone area and thickness
• Glucose metabolism

This metabolic profile makes creatine particularly relevant for people managing weight, blood sugar, or osteoporosis risk.
