Phytoceramides
Replenish the lipids that make up 50% of the skin barrier — oral phytoceramides restore hydration and reduce wrinkles from within.
What the evidence says
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.

Ceramides has an evidence score of 9/10 — very strong evidence based on 15 indexed studies, including 10 meta-analyses. Replenish the lipids that make up 50% of the skin barrier — oral phytoceramides restore hydration and reduce wrinkles from within.
The commonly studied dose of Ceramides is 350mg wheat-derived ceramides or 30-40mg glycosphingolipids daily. Individual needs vary — start at the lower end of the range and adjust based on how you respond.
The best time to take Ceramides is with meals. Take it with food. Phytoceramides are sphingolipids — lipid-based compounds that require bile acid emulsification and lipase activity for intestinal absorption.

Ceramides are lipids naturally found in the skin's outer layer, making up about 50% of the skin barrier. As we age, ceramide levels decline, leading to drier skin and wrinkles. Oral phytoceramides (derived from plants like wheat or rice) can help replenish these essential lipids from within, supporting skin hydration, barrier function, and reducing signs of aging.

Take with food
| Form | Type |
|---|---|
| 💊Wheat-derived phytoceramides (Ceramide-PCD) | Recommended |
| 💊Rice-derived ceramides (gluten-free option) | Alternative |
| 💊Sweet potato ceramides | Alternative |
Wheat ceramides are most researched. Those with gluten sensitivity can use rice or sweet potato-derived forms.
Minimum: 4 weeks
Optimal: 12 weeks
Cycling: Not required
Note: Taking with food (especially containing fat) improves absorption.
Dose-response data unavailable. The current published research for Ceramides does not provide sufficient dose-specific outcome data to generate reliable dose-response curves.
Refer to the Dosage & Timing section above for recommended dose ranges based on available evidence.
More moisturized, supple skin
Visible reduction in fine lines
Less reactive, better protected skin
Use rice or sweet potato-derived ceramides instead
Limited research on interactions; inform healthcare provider of all supplements
Tip: Take with food
Ceramides is generally well-tolerated and considered safe for most healthy adults at recommended doses. The most commonly reported side effects are GI upset. Use caution if any of these apply to you: Wheat allergy (for wheat-derived forms).
