Alzheimer’s disease is a progressive neurodegenerative condition that affects memory, thinking, and behavior. While there is no cure, medical treatments and lifestyle strategies aim to slow cognitive decline, support function, and improve quality of life.
In addition to prescribed medications, certain supplements and dietary interventions have been studied for potential cognitive benefits. Below we summarize the evidence on at least five such approaches—including medium‑chain triglyceride (MCT) oil and ketogenic diets—describe possible mechanisms, and explain how the Ayuda Health app can help support daily life for those living with Alzheimer’s disease.
Supplements and Dietary Strategies With Evidence
1. Medium‑Chain Triglyceride (MCT) Oil and Ketogenic Diets
What they are:
-
MCT oil is a source of fats that are rapidly absorbed and converted by the liver into ketone bodies.
-
Ketogenic diets are very low‑carbohydrate, high‑fat diets that promote ketone production.
Clinical Evidence:
Clinical trials indicate that ketone bodies may serve as an alternative energy source for the brain in people with Alzheimer’s who have impaired glucose metabolism. Trials of MCT oil and ketogenic interventions have shown improvements in cognition, memory, or certain biomarkers in some patients with mild to moderate Alzheimer’s.
Proposed mechanisms:
-
Ketones can bypass impaired glucose utilization in neurons.
-
They provide an alternative and efficient energy substrate for the brain.
-
Ketosis may reduce oxidative stress and inflammation.
Notes:
Ketogenic diets should be implemented with medical supervision, especially in older adults or those with medical comorbidities.
2. Omega‑3 Fatty Acids (EPA/DHA)
What they are:
Found primarily in fish oil, EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are polyunsaturated fats important for brain health.
Clinical Evidence:
Some large epidemiologic studies and clinical trials suggest that higher intake of DHA/EPA is associated with slower cognitive decline and reduced risk of Alzheimer’s progression, especially when started early or in people with mild cognitive impairment.
Proposed mechanisms:
-
Support neuronal membrane integrity
-
Reduce neuroinflammation
-
Improve cerebral blood flow
Notes:
Results from clinical trials are mixed, but many experts recommend adequate fish intake or omega‑3 supplementation as part of a brain‑healthy pattern.
3. Curcumin (Turmeric Extract)
What it is:
Curcumin is the principal bioactive compound in turmeric with anti‑inflammatory and antioxidant effects.
Clinical Evidence:
Some small human trials and animal studies suggest curcumin may reduce amyloid plaque accumulation and oxidative stress, though larger clinical trials are needed for definitive conclusions.
Proposed mechanisms:
-
Antioxidant and anti‑inflammatory actions
-
Potential modulation of amyloid aggregation and tau pathology
Notes:
Curcumin’s bioavailability is limited; formulations with enhanced absorption are often studied.
4. Resveratrol
What it is:
A polyphenol found in grapes, berries, and red wine.
Clinical Evidence:
Small clinical studies indicate resveratrol may influence biomarkers of Alzheimer’s disease and reduce inflammation, with some effects on amyloid and tau markers in cerebrospinal fluid.
Proposed mechanisms:
-
Activates sirtuin pathways
-
Reduces oxidative stress
-
Modulates neuroinflammatory responses
Notes:
Benefits appear modest; long‑term safety and efficacy require further research.
5. B Vitamins (Folate, B6, B12)
What they are:
B vitamins are essential for methylation and homocysteine metabolism.
Clinical Evidence:
Elevated homocysteine is associated with cognitive decline. Supplementation with folate, B6, and B12 can reduce homocysteine levels and has been studied for cognitive benefit, particularly in people with elevated homocysteine at baseline.
Proposed mechanisms:
-
Lower homocysteine, potentially reducing vascular and neuronal damage
-
Support neurotransmitter synthesis
Notes:
Effect on cognition varies; benefits may be greater when deficiency is present.
Other Nutrients of Interest
Vitamin D:
Vitamin D deficiency is common in older adults and may relate to cognitive decline; supplementation when deficient is clinically reasonable.
Antioxidants (Vitamin E):
Vitamin E has been studied for slowing functional decline in Alzheimer’s, with mixed results and some safety considerations at high doses.
How Ayuda Health Helps People Living With Alzheimer’s Disease
Ayuda Health is a digital self‑management platform that supports people with chronic neurological conditions—including Alzheimer’s—by helping organize care routines, monitor key health patterns, and enhance communication with caregivers and clinicians.
1. Medication Reminders & Adherence Tracking
-
Align your existing daily habits to reminders for medications medications such as:
-
Cholinesterase inhibitors (donepezil, rivastigmine, galantamine)
-
NMDA receptor antagonist (memantine)
-
-
Track doses taken vs. missed in a report for your health team
-
Add caregivers who are notified when a dose is missed
2. Care Planning & Routines
-
Calendarize daily routines (meals, medications, appointments)
-
Set and calendarize goals for for therapeutic activities (e.g., memory exercises)
3. Tracking Cognitive and Daily Function
-
Use your smartphone’s voice-to-text feature to log mood, memory lapses, sleep, symptoms/side effects
-
Identify patterns that influence function
4. Reports for Clinical Visits
-
Generate shareable summaries of medication adherence, vitals, and symptoms
-
Support more productive clinician visits
5. Care Team Coordination
-
With permission, caregivers can receive alerts for missed medications and scheduled events
-
Enhances communication among family members, caregivers, and clinicians
6. Educational Support
-
Through the AI assistant (Yubi), users and caregivers can ask general health questions
-
Receive supportive guidance (not clinical diagnosis)
Ayuda Health helps reduce the cognitive and administrative load of living with Alzheimer’s, supporting consistency and better engagement with daily care.

Frequently Asked Questions (FAQ)
Can supplements cure Alzheimer’s disease?
No. Supplements may support brain health or slow decline in some studies, but no supplement cures Alzheimer’s. They should be used as adjuncts under clinical guidance.
Are these supplements safe?
Safety varies by supplement, dose, and individual health status. Consult a healthcare provider before starting any new supplement, especially in Alzheimer’s where polypharmacy and nutrition are common concerns.
Is diet more important than supplements?
Both diet and supplements can contribute to overall health, but a whole‑food, nutrient‑rich diet has stronger evidence overall. Dietary patterns like Mediterranean or MIND diets are widely studied in cognitive aging.
How long until supplements show effects?
Effects—which may be modest—typically take weeks to months and vary among individuals.
Does Ayuda Health replace my clinician?
No. Ayuda Health supports management and communication but does not replace professional medical care or diagnosis.
