15 peer-reviewed studies
What the evidence says
Mostly mechanism / observational
Most Ceramides studies are mechanism or observational rather than RCTs that measure a clinical effect — keep findings provisional.
Most evidence is from high-quality meta-analyses and randomised trials published 2017–2026 with a typical study size of 60 participants.

Oral phytoceramide supplementation significantly improved skin hydration and reduced transepidermal water loss in clinical studies.
Tessema EN et al. · Journal of Cosmetic Dermatology (2021)
Oral phytoceramides significantly increased skin hydration measured by corneometry
Transepidermal water loss (TEWL) was significantly reduced after 4-12 weeks
Both wheat-derived and rice-derived phytoceramides showed efficacy
7Emotional well-being and psychiatric disordersSystematic Review2026
Journal of Neurochemistry published by John Wiley & Sons Ltd on behalf of International Society for Neurochemistry.
Kalinichenko LS et al. · Journal of neurochemistry (2026)
Multiple studies show the contribution of SLs to normal brain functioning and corresponding beneficial behavioral phenotypes, such as stress resilience, cognitive performance, and social interactions, which determine emotional well-being.
On the other hand, an imbalance in SL metabolism affects normal functioning of cells and thus contributes to the development of several psychiatric disorders, such as depression, anxiety, cognitive decline, schizophrenia, and others.
SLs are suggested as a potentially new mechanism of the key behavioral manifestations of emotional well-being, which might be further investigated as new biomarkers of life quality as well as physical and mental resilience.
Finally, the review concludes with remarks and prospects for the future of curcumin's antitumor potential in the context of ceramide targeting.
Dehnavi S et al. · Molecular biology reports (2026)
This review primarily introduces ceramides and their metabolism, summarizes their crucial roles in cancer, and categorizes and discusses the mechanisms and pathways through which curcumin could potentially exert its antitumor effects by targeting ceramides.

Nutritional strategies targeting ceramide metabolism represent a promising approach to improve metabolic health.
Arias-Marroquín AT et al. · Clinical nutrition ESPEN (2025)
Nutritional strategies targeting ceramide metabolism represent a promising approach to improve metabolic health.
Beyond their therapeutic potential, ceramides also emerge as dynamic lipidomic biomarkers capable of reflecting early metabolic changes and monitoring the efficacy of nutritional interventions.
While some evidence is promising, the reliability of these products, as well as their optimal dosage and frequency, remains uncertain.
Cespedes Zablah A et al. · Dermatitis : contact, atopic, occupational, drug (2024)
Oral ceramides, blackcurrant seed oil, and hempseed oil have yet to be thoroughly studied, but preliminary results are promising.
Among the studies, the supplementation doses and duration of treatment varied extensively.
The literature did not provide comparative analysis between the supplements, and data on the overall safety and tolerability of these supplements are limited.
Alcohol, coffee, and multivitamins are associated with several metabolites and lipid species.
Khan S et al. · Metabolomics : Official journal of the Metabolomic Society (2026)
Alcohol, coffee, and multivitamins are associated with several metabolites and lipid species.
These findings offer valuable insights into potential biomarkers of exposure and molecular pathways through which these exposures may be associated with health outcomes.
