Alzheimer's Prevention & Brain Health Protocol
A prevention-first routine of resistance training, targeted supplementation and sleep timing aimed at the modifiable, lifestyle-driven side of Alzheimer's and cognitive decline risk.
Nicola's core message is that Alzheimer's pathology often begins decades before diagnosis, and that a meaningful share of that risk is modifiable through lifestyle. Her protocol centers on heavy resistance training (leg strength in particular correlates with brain volume in her cited twin studies), a short weekly high-intensity interval session, creatine and omega-3 supplementation dosed higher than typical fitness-industry advice, vitamin D to a blood-level target, breaking up sitting, and a sleep routine that protects the brain's overnight waste-clearance (glymphatic) system. None of this diagnoses, treats or cures Alzheimer's disease; it is presented as risk-reduction, and genetic/blood biomarker testing should go through a clinician.
Why it works▼
Heavy compound resistance training
Leg strength specifically correlates with greater brain volume and better cognition in her cited twin-study data; myokines from resistance training support frontal lobe function.
High-intensity interval session (Norwegian 4x4)
Raises VO2 max; she cites a Ben Levine study of previously sedentary adults reversing measures of heart aging over 2 years using varied training including intervals.
Break up sitting (a squat snack)
Cerebral blood flow drops within a few hours of continuous sitting; brief movement reverses this. She cites accelerometer research linking very high daily sitting time to higher dementia risk even in people who exercise.
Creatine monohydrate
Higher doses are needed for meaningful amounts to cross the blood-brain barrier; she cites a small pilot study in Alzheimer's patients showing preserved cognitive function. This dose is well above typical labels and long-term safety data at this range is thinner than for the standard 5g dose, so treat it as emerging, not settled.
Omega-3 (EPA/DHA)
DHA is a major structural fat in the brain; she flags that many over-the-counter omega-3 products are already oxidized by the time they're taken, which is why storage matters as much as dose.
Vitamin D to a blood-level target
She cites observational data linking vitamin D deficiency to higher all-cause dementia risk. Dosing should track an actual blood test, not be taken blind, since needs vary by baseline level and body size.
Sleep wind-down for glymphatic clearance
Deep sleep drives the brain's glymphatic (waste-clearance) system; she cites data that even one night of poor sleep is associated with a short-term rise in amyloid-beta.
- Adults with a family history of Alzheimer's or dementia
- Anyone wanting a prevention-first, lifestyle-based brain health routine
- People already strength training who want to add brain-specific dosing logic
- Not a replacement for diagnosis, genetic counseling, or treatment of existing cognitive impairment
- Informational only, not medical advice; does not diagnose, treat, prevent or cure Alzheimer's disease or any condition
- Creatine doses above 5g/day (the 12-20g range cited here) exceed the most well-studied dose and long-term safety data at this range is limited; talk to a clinician, especially with kidney concerns
- High-intensity interval training: check with a doctor first if you have any cardiovascular condition
- Vitamin D and genetic (APOE4) or blood biomarker testing should be interpreted with a clinician, not self-diagnosed
- Some claims come from observational studies or single pilot studies, not large randomized trials; treat as suggestive, not proven
