Abstract

The TED (Tired–Exercise–Diet) model within the NeuroAffective-CBT® (NA-CBT) framework integrates lifestyle-based interventions with affect-focused psychotherapy to support emotional regulation, particularly in shame-based and affect-dysregulated disorders. This article presents a narrative, theory-integrative review exploring the emerging role of creatine supplementation as a potential neurometabolic adjunct within this model. Traditionally associated with muscular performance, creatine has gained neuroscientific attention for its role in cerebral energy metabolism, mitochondrial function, and stress resilience. Evidence from animal studies, neuroimaging research, and early-stage human trials suggests that creatine supplementation may enhance brain bioenergetics, attenuate cognitive deficits under metabolic stress, and augment established treatments for depression when used adjunctively. Of particular relevance, a recent randomized, double-blind, placebo-controlled pilot trial reported greater reductions in depressive symptoms when creatine was combined with cognitive-behavioural therapy compared to therapy alone. While findings remain preliminary and heterogeneous, they support a neuroaffective perspective in which metabolic support may enhance the brain’s capacity for emotional learning and regulation. The article situates creatine within the TED framework, emphasising its potential as a supportive, individualised, and ethically integrated lifestyle intervention, while underscoring the need for larger, well-controlled clinical trials before routine clinical implementation.

The TED Series: Introduction

This article forms part of a TED (Tired–Exercise–Diet) series comprising eight articles examining supplements and lifestyle-related factors that may influence mental health. Across the series, each instalment focuses on a specific nutritional compound, behavioural factor, or physiological mechanism relevant to mental health, emotional regulation, nutrition, exercise, and sleep, with the overarching aim of clarifying how these elements interact to define practical, evidence-informed lifestyle interventions.

In this first instalment of the TED series, the article explores the intriguing possibility that creatine supplementation, long associated with sports performance, may also play a role in mental health—particularly in disorders rooted in shame, self-hatred, self-criticism, and broader affect dysregulation. Subsequent articles will extend this framework to other supplements and lifestyle variables, progressively building an integrated model of how sleep, movement, and nutrition can be leveraged to support psychotherapeutic change within the NeuroAffective-CBT® framework.

Introducing TED in the NeuroAffective-CBT® Framework – Mirea’s Contribution

The TED model (Tired-Exercise-Diet) synthesises insights from neuroscience (e.g., gut–brain signalling, reward pathways), nutritional psychiatry, psychophysiology (e.g., sleep deprivation), and behavioural science (habit formation, conditioning). By organising these findings into three core domains, sleep, exercise, and diet, TED provides an accessible, flexible, and evidence-informed structure for lifestyle-oriented intervention.

But TED is not just theoretical: it is publicly presented and described by Daniel Mirea in the NeuroAffective-CBT® literature. Mirea’s “Tired, Exercise and Diet Your Way Out of Trouble” (TED model) is available via ResearchGate, Academia, and the NA-CBT site as a leaflet and white-paper introduction to emotional regulation through lifestyle (Mirea, 2023). In his description, the TED module is positioned centrally within the NA-CBT method, linking body, brain, and affect, the Body–Brain–Affect triangle (Mirea, 2025).

Within the larger NeuroAffective-CBT® programme (comprising six modules), TED is introduced early, immediately after assessment and conceptualisation. NA-CBT specifically targets shame-based disorders such as self-loathing, self-disgust, and low self-esteem, which often underpin psychopathologies like major depressive disorder and anorexia (Mirea, 2023). Addressing lifestyle factors may augment traditional CBT approaches (Firth et al., 2020; Lopresti, 2019).

Empirical evidence shows that improving sleep, increasing physical activity, and enhancing diet quality yield synergistic benefits for emotional regulation, reduction of maladaptive cravings, and improvement of self-esteem (Kandola et al., 2019; Irwin, 2015).

For clinicians, TED offers a concrete tool: integrate lifestyle domains early, personalise interventions, and use TED to amplify CBT. For researchers, it highlights testable mechanisms and opportunities for controlled trials.

This first part focuses on a lesser-known nutritional agent now attracting neuroscientific attention: creatine, a compound with emerging evidence linking it to neuroenergetics and mental health (Candow et al., 2022; Allen et al., 2024).

Why Creatine? What the Evidence Suggests (and Doesn’t..)

Drawing on emerging neuroscience and clinical psychology research, Dr Wendy Suzuki has highlighted creatine’s shift from a narrowly defined “gym supplement” to a promising neurometabolic support under conditions of brain stress. Although the liver and brain synthesize small endogenous amounts of creatine, supplementation appears most relevant during periods of elevated cognitive demand, sleep deprivation, depression, or neurodegenerative vulnerability, states marked by energetic strain, inflammation, and oxidative stress. While low-dose creatine (≈5 g/day) effectively supports muscular performance, studies from European and North American laboratories indicate that higher doses (≈10 g/day or more) may be required to meaningfully elevate brain creatine levels once muscular stores are saturated. Experimental sleep-deprivation models further suggest that acute high-dose creatine can reverse cognitive deficits, and in some cases restore performance beyond well-rested baselines, pointing to rapid effects on cerebral energy metabolism rather than slow structural adaptation. Of particular relevance to NeuroAffective-CBT, a recent Harvard-affiliated randomised, double-blind, placebo-controlled pilot trial found that individuals with depressive symptoms who received creatine monohydrate (5 g/day) alongside cognitive-behavioural therapy experienced significantly greater reductions in PHQ-9 depression scores than those receiving CBT alone, without increased adverse events (Sherpa NN et al., 2025). While preliminary animal and early human studies also suggest anti-inflammatory and neuroprotective effects, along with small pilot signals in conditions such as Alzheimer’s disease, the evidence base remains emergent. Taken together, current findings support a neuroaffective framework in which creatine may enhance the brain’s energetic resilience, potentially amplifying psychotherapeutic efficacy under stress, while underscoring the need for larger, well-controlled trials before broad clinical recommendations are made.

The Rationale: Bioenergetics, Oxidative Stress, and Brain Demand

Creatine helps the body make and recycle energy quickly. It acts like a backup battery for your cells, keeping them charged when energy demand is high. While we often think of creatine as something that helps muscles perform better, the brain also uses a huge amount of energy, about one-fifth of everything the body burns at rest.

In people experiencing depression or anxiety, studies suggest that the brain’s mitochondria (the cell’s “power stations” that turn food into usable energy) often don’t work as efficiently. This can lead to higher levels of oxidative stress – a kind of cellular “wear and tear” caused by unstable oxygen molecules that damage cells over time (Morris et al., 2017).

Taking creatine as a supplement may help the brain’s mitochondria work more efficiently, reduce oxidative stress, and stabilise the brain’s energy balance (Allen et al., 2024). Animal studies show that creatine can reduce stress in brain cells and even decrease depression-like behaviours (Zhang et al., 2023). Research in humans is still early, but the results so far are promising.

💡 In simple TED terms:
Why Creatine Might Help the Brain: Energy and Stress Balance! Creatine may help the brain produce cleaner, steadier energy, while reducing the internal “rust” that builds up from stress and poor metabolism, both of which are key targets in emotional regulation.

Human Evidence: Mood, Cognition, and Stress Conditions

Mood and Depression

Early studies suggest that creatine may help boost the effects of antidepressant medication. In one carefully controlled trial, women who took 5 grams of creatine monohydrate per day alongside their usual SSRI antidepressant showed faster and stronger improvements in mood than those taking a placebo (Lyoo et al., 2012).

Several reviews of this research confirm that creatine seems most effective as an add-on rather than a stand-alone treatment (Allen et al., 2024; L-Kiaux et al., 2024). In other words, creatine may make existing treatments work better, but it is not yet proven to work on its own.

Although there have been no large human trials testing creatine by itself for depression or PTSD, brain-imaging studies show that creatine supplementation increases the brain’s phosphocreatine levels (the stored form of cellular energy). This may help restore low brain-energy levels often found in people with mood disorders (Dechent et al., 1999; Rae & Bröer, 2015).

💡 TED translation: Creatine may act like an energy booster for the brain, helping antidepressants “catch” faster and work more effectively. Within the TED framework, this fits the Diet domain, using nutrition to support energy stability and emotional regulation and, complements therapeutic work in the Affect domain.

Cognition, Memory, and Sleep Deprivation

Research also shows that creatine can help the brain think and react more effectively, especially when it is under pressure. Systematic reviews indicate that creatine can enhance memory, focus, and processing speed in conditions of metabolic stress, such as sleep deprivation, oxygen deprivation, or prolonged mental effort (Avgerinos et al., 2018; McMorris et al., 2017).

In one notable experiment, people who stayed awake all night performed better on reaction-time tasks and reported less mental fatigue after taking creatine (McMorris et al., 2006). These benefits appear strongest in older adults or individuals whose brains are already energy-challenged, for example, due to stress, ageing, or poor sleep (Dolan et al., 2018). In contrast, young, well-rested participants often show little or no change (Simpson & Rawson, 2021).

💡 TED translation: Creatine seems to protect the brain when energy is low during exhaustion, stress, or lack of sleep. This is what we call a reactive emtional state (reactive amygdala). It doesn’t make a healthy, rested brain “smarter,” but it helps a tired brain function more efficiently. In TED terms, it bridges the Tired and Diet domains: improving sleep quality indirectly and supporting cognitive endurance under pressure.

Key Questions & Considerations

Dose, Duration, and Uptake

A few muscle studies, led by Dr. Darren Candow, show that taking 3–5 grams of creatine monohydrate per day is enough to maintain muscle levels once stores are full. To load the system faster, some use about 20 grams per day for 5–7 days, which quickly saturates muscle tissue (Candow et al., 2022; Kreider et al., 2017).

However, the brain takes longer to absorb creatine. Imaging studies suggest that at least 10 grams per day for several weeks may be needed to raise brain levels meaningfully (Dechent et al., 1999; Rae & Bröer, 2015). Because around 95% of the body’s creatine is stored in muscle, the brain receives its share more slowly, which may explain why mood or cognitive effects sometimes take weeks to appear.

💡 TED translation: Creatine needs time to “charge the system”. Like building savings in a bank, the longer and more consistently you invest, the better the returns. Within TED, this reflects the Tired and Diet domains, combining steady supplementation with sleep and nutrition for sustained brain energy.

Sodium and Electrolyte Co-Ingestion

Creatine is carried into cells by a sodium-chloride transporter (called SLC6A8) (Tachikawa et al., 2013). This means that electrolytes, especially sodium, help creatine get where it needs to go. While not yet proven for brain outcomes, pairing creatine with a small amount of electrolyte water or a balanced meal containing sodium may improve absorption.

💡 TED translation: Think of sodium as a helper molecule, like a key that lets creatine into the cell. In TED language, this links Diet with Physiology: hydration, electrolytes, and nutrition work together to optimise energy flow.

Dietary Status

People who eat little or no animal protein, such as vegetarians or vegans, often start with lower creatine stores and therefore show a greater response to supplementation (Candow et al., 2022; Antonio et al., 2021). Interestingly, brain creatine levels appear to stay relatively stable across diet types, which suggests the brain has its own built-in regulation system (Rae & Bröer, 2015).

💡 TED translation: Your baseline diet changes how quickly you benefit from creatine. If you avoid animal foods, your muscles may “fill up” faster when you supplement but the brain keeps itself balanced. This reflects TED’s Diet principle: individualisation matters.

Safety and Misconceptions

Decades of studies confirm that creatine monohydrate is safe for healthy adults. No evidence links standard doses (3–5 g/day) to kidney or liver problems (Kreider et al., 2017; Harvard Health Publishing, 2024). Increases in serum creatinine after supplementation simply reflect higher turnover, not kidney damage.

The often-mentioned hair-loss claim remains unsupported (Antonio et al., 2021). However, clinicians should note that in rare cases, individuals with bipolar disorder have reported manic switching after starting creatine (Silva et al., 2013). These cases are very uncommon but worth monitoring in sensitive populations.

💡 TED translation: Creatine is one of the safest, best-studied supplements in both sport and health science. Still, as with all lifestyle tools, TED encourages personalisation and medical oversight, particularly in those with complex mental-health or metabolic conditions.

Implications for TED and NeuroAffective-CBT®

In clinical contexts, creatine should be understood as a supportive, adjunctive tool rather than a substitute for established psychotherapeutic or pharmacological treatments. Its value lies in its potential to stabilise metabolic and energetic foundations that may facilitate emotional learning and regulation. Accordingly, creatine supplementation should be implemented thoughtfully, within a broader clinical formulation, and under appropriate medical supervision.

Practical Guidelines

Screen and personalise
Prior to supplementation, assess renal function, dietary patterns, and potential interactions with prescribed medications. Additional caution is warranted in individuals with pre-existing renal, metabolic, or psychiatric vulnerabilities.

Adjunctive use only
Creatine should complement—not replace—psychotherapy or pharmacological treatment. Supplementation is best undertaken with oversight from a GP or psychiatrist, particularly when active mental health treatment is required.

Dosing strategy
A short loading phase of approximately 20 g/day for 5–7 days, or a more gradual titration of 10–20 g/day over four weeks, may be followed by a maintenance dose of 3–5 g/day, depending on tolerance and clinical response (Candow et al., 2022).

Timing considerations
Creatine may be most beneficial during periods of sleep disruption, sustained cognitive demand, or emotional exhaustion, when cerebral energy requirements are elevated.

Integration within TED
For optimal benefit, supplementation should be integrated with the other TED domains—sleep hygiene, structured physical activity, and a nutrient-dense diet—to support synergistic effects on emotional regulation and cognitive resilience (Firth et al., 2020).

Monitoring and documentation
Clinicians and clients are encouraged to systematically monitor mood, cognitive clarity, sleep quality, and physical functioning. Dosing may be adjusted empirically, and anonymised observations can contribute to practice-based evidence and future research.

💡 TED translation: Creatine fits naturally within the Tired–Exercise–Diet framework as a form of metabolic support for emotional regulation. Rather than functioning as a “pill for a problem,” it is best conceptualised as one component of a whole-lifestyle system in which sleep, movement, and nutrition work together to reinforce psychological recovery.

Summary & Outlook

• The TED model (sleep, exercise, diet) offers a practical bridge between psychotherapy and lifestyle science, especially for conditions rooted in shame, self-criticism, and affect dysregulation (Firth et al., 2020; Lopresti, 2019).
• Creatine demonstrates strong scientific plausibility and early clinical promise for improving mood, cognition, and resilience under metabolic stress (Allen et al., 2024; Candow et al., 2022).
• The next step for researchers is to conduct large, placebo-controlled clinical trials testing creatine as an adjunct to CBT for depression and anxiety — ideally with neuroimaging to confirm its effects on brain energy metabolism.

💡 TED translation: Creatine may one day become a recognised “nutritional ally” for the brain, enhancing therapy outcomes by helping clients feel less tired, more focused, and more emotionally stable. For now, it serves as a valuable prototype of how lifestyle science can empower both clinicians and clients to target emotional health from the body upward.

⚠️ Disclaimer:
A final and important reminder: these articles are not intended to replace professional medical or psychological assessment and/or treatment. Regular blood tests and health check-ups with your GP or a private family doctor are essential throughout adult life, in fact increasingly relevant from adolescence onward, given the rising incidence of metabolic and endocrine conditions such as diabetes among young people. It is strongly recommended to seek guidance from qualified professionals, for example, a GP or a psychiatrist, depending on your personal goals and needs a registered nutritionist, indeed a certified NeuroAffective-CBT® practitioner, who can help interpret your health data (including blood work) and help you understand how your lifestyle, daily habits, and nutritional choices influence your mental and emotional wellbeing.
