23 Jul 2026 Creatine’s boom gets a boost from new mental health research

Creatine has officially broken out of the gym….

Once the domain of bodybuilders and sports nutrition die‑hards, the ingredient is surging into mainstream wellness, driven by consumer interest in strength, healthy ageing and everyday performance.

Now, early research out of Canada suggests a possible link to mental health benefits.

A new systematic review from the University of Ottawa has put creatine back in the spotlight, exploring whether the compound could play a role in supporting people with depression.

The findings aren’t conclusive — but they’re intriguing enough to accelerate industry attention.

Why creatine is suddenly everywhere

Creatine is a naturally occurring compound found in muscle cells, central to energy production during high‑intensity activity.

Consumers increasingly associate it with strength, mobility, ageing well, and “functional fitness”, a trend pushing brands across beverages, snacking and even confectionery to experiment with creatine fortification.

Beyond its well-documented benefits for enhancing physical performance, there is growing interest in creatine’s potential therapeutic value for brain health and psychiatric disorders.

The mental health angle: promising but early

Scientists have long known that creatine fuels more than muscle — the brain uses the same energy system, prompting researchers to ask whether creatine could support mental wellbeing.

The new review analysed five randomised controlled trials involving people with major depressive disorder or bipolar‑related depressive episode.

• Two trials showed meaningful improvements in depressive symptoms.
• Three trials showed no measurable benefit.

Researchers emphasise that the evidence is far from definitive, but biologically plausible. The brain’s high energy demand, creatine’s role in ATP regeneration, and observed changes in creatine metabolism among people with mood disorders all point to a mechanism worth exploring.

Creatine may also influence dopamine and serotonin, neurotransmitters targeted by antidepressants, though this remains theoretical.

As lead author Bassam Jeryous Fares puts it: “The signal is interesting, but it is not a verdict.”

Safety isn’t a major concern either, with reported side effects limited to mild gastrointestinal discomfort.

Scope for food & beverage brands

The emerging mental‑health angle gives creatine new storytelling territory, especially for brands targeting:

• older adults
• busy professionals
• consumers seeking everyday cognitive or mood support
• wellness‑focused snackers and beverage buyers

As creatine is being positioned as a daily‑use functional, not just a gym supplement, innovation is already expanding beyond powders into RTDs, bars, gummies, snacks and confectionery
