Overall, 3/17 studies carried a low risk of bias.
Dewsbury LS et al. · Advances in nutrition (Bethesda, Md.) (2021)
Overall, 3/17 studies carried a low risk of bias.
Based on available evidence, exogenous ketogenic agents may be more feasible than dietary interventions in NDD from a compliance and adherence perspective; more research is required to confirm this.
13Clinical benefits of exogenous ketosisSystematic ReviewCited 4×2025
Exogenous ketosis shows potential in neurological, metabolic, and cardiovascular disorders, while evidence in psychiatric and inflammatory conditions remains scarce and preliminary.
Mohib O et al. · Nutrients (2025)
Exogenous ketosis shows potential in neurological, metabolic, and cardiovascular disorders, while evidence in psychiatric and inflammatory conditions remains scarce and preliminary.
Ketone esters appear preferable for effective and tolerable ketosis.
Future research should focus on identifying responsive patient populations, optimizing treatment regimens, and conducting long-term clinical trials with hard endpoints to validate these findings.
14AMPA receptor modulation through MCTs in pediatric epilepsySystematic ReviewCited 1×2025
The summarized findings reinforce the therapeutic potential of MCTs, highlighting both the beneficial seizure outcomes and the hurdles that remain to be addressed through future research.
Falsaperla R et al. · Nutrients (2025)
Methods: A systematic review was conducted, including articles from January 2000 to January 2025, to explore the potential role of medium-chain triglyceride (MCT) add-on to classic KD and as MCT supplementation in free diets in the management of pediatric drug-resistant epilepsy (DRE).
Results: Selected studies show how the action of MCTs, and decanoic acid in particular, is via negative modulation of AMPA receptors, with a positive impact on epileptic seizures.
Conclusions: This review discusses the complexities of implementing and sustaining KD in children and presents recent pre-clinical and clinical evidence, including trials where MCTs (often enriched in decanoic acid) serve as an add-on therapy in both ketogenic and free/unrestricted diets.
Limitations include heterogeneous intervention conditions, such as different types of dispersions, caffeine intake, limited number of studies and variability in study design.
Frenser M et al. · Nutrients (2024)
Forest plot analysis showed heterogeneous data.
The data suggest a non-linear relationship between C8, carbohydrate intake and ketone production.
Further studies are needed to investigate the influence of different carbohydrates on C8-induced ketogenesis.
18Weight loss and metabolic healthMeta-AnalysisCited 8×2024
Hence, the authors recommend incorporating pure MCTs in dietary interventions for individuals with overweight and obesity, particularly those with comorbidities such as dyslipidemia and impaired glucose metabolism.
He H et al. · Clinical nutrition (Edinburgh, Scotland) (2024)
However, our subgroup analysis indicates that an MLCTs-enriched diet did not significantly reduce weight loss.
Additionally, MCTs-enriched diets were associated with significant reductions in blood triglyceride levels and Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) scores, compared to LCTs-enriched diets.
Hence, the authors recommend incorporating pure MCTs in dietary interventions for individuals with overweight and obesity, particularly those with comorbidities such as dyslipidemia and impaired glucose metabolism.
In this meta-analysis, we demonstrated that MCTs can induce mild ketosis and may improve cognition in patients with mild cognitive impairment and Alzheimer's disease.
Avgerinos KI et al. · Ageing research reviews (2020)
In this meta-analysis, we demonstrated that MCTs can induce mild ketosis and may improve cognition in patients with mild cognitive impairment and Alzheimer's disease.
However, risk of bias of existing studies necessitates future trials.
MCT supplementation may enhance working memory in non-demented older adults.
Giannos P et al. · BMC geriatrics (2022)
MCT supplementation may enhance working memory in non-demented older adults.
These effects may be more prominent in individuals with lower baseline scores, from short and long-term supplementation.
Further studies are warranted to confirm these findings in terms of optimal dose and MCTs composition, which may protect from memory decline during aging.
