Key Takeaway
15-month RCT showed MCT oil (42g/day) stabilized cognition in Alzheimer's patients over 9 months of continuous use
Summary
This rigorous study examined the effects of MCT oil supplementation in subjects with probable Alzheimer's disease over an extended period. The study used a crossover design followed by an open-label extension, providing both controlled and long-term observational data.
Methods
- Design: 6-month randomized, double-blind, placebo-controlled, crossover study with 6-month open-label extension
- Participants: Adults with probable Alzheimer's disease
- Intervention: 42g/day MCT oil vs placebo
- Duration: 15 months total (6 months crossover + 6 months extension)
- Outcomes: Cognitive assessments, ketone levels
Key Results
- MCT oil significantly elevated serum ketone bodies
- Cognitive stabilization observed over 9-month exposure period
- The trial suggests continuous daily nutritional ketones may stabilize cognition
- Results support MCT as a potential adjunctive therapy for AD

Limitations
- Small sample size limits generalizability
- Single-center study
- Compliance challenges with 42g daily dose
- Open-label extension introduces potential bias
- Results need replication in larger trials
