Energy balance

Interventions that raise ketone availability (via MCT oil, ketogenic diets, or ketone esters) improve cognitive outcomes in individuals with Mild Cognitive Impairment (MCI) and Alzheimer's Disease (AD).

If you or a loved one has MCI or early Alzheimer's, raising ketone levels through MCT oil, a ketogenic diet, or ketone supplements may help improve cognitive function. This works by providing an alternative fuel source to the brain when glucose utilization is impaired. Consult a doctor before starting, especially if on medication.

Interventions that raise ketone availability to the brain improve cognitive outcomes in both MCI and AD as well as in acute experimental hypoglycemia.
