Video 11: Supplements and Vitamins
In collaboration with BrainMind, Dr. Isaacson discusses vitamins and supplements for optimal brain health at Alzheimer’s prevention
About Dr. Richard Isaacson:

He is currently the director of Brain Health at the Atria Institute. A leading expert on Alzheimer’s Disease (AD), Dr. Isaacson is passionate about providing the latest evidence-based options for treatment and risk reduction. His research focuses on individualized clinical management of AD using emerging principles of precision medicine. He also oversees a robust AD therapeutics and education research program.
Few things to note:
● The most optimal way of intaking vitamins and nutrients is by eating whole foods rather
than taking pills.
● Sometimes, eating healthy food (ie. Omega-3 fatty acid through fish) is not enough.
● There is strong evidence that certain vitamins and supplements can have an impact on
brain health
What are high-yield evidence-based vitamins?
1. B-Complex Vitamins
2. Vitamin D
B-Complex Vitamins: brain healthy, but not everyone needs it
● Blood assessment is useful to determine if a person has B12 deficiency and an unusual
level of homocysteine
○ B12 deficiency arise because people above the age of 50 have problems absorbing B12 in the GI tract
○ Homocysteine: common amino acid in your blood, usually obtained from eating meat, and B12 is used to lower homocysteine level
● Most Important B Vitamins:
1. Vitamin B12
2. Folic Acid
3. Vitamin B6
Vitamin D
● The optimal blood level of vitamin D is ~50 (people with two APOE4 variants especially
respond better to vitamin D, reducing cognitive decline)
○ Optimal intake of Vitamin D depends on genetic factors
● Important Fact: Take vitamin D with meals including healthy fats, not on an empty
stomach because it won’t be absorbed without a fat
Omega-3 Fatty Acids
● The most brain-healthy supplement (for specific populations because people with
different genes may respond differently)
○ People with APOE4 or high cholesterol may preferentially respond
● Which Omega-3 should you take?
○ Must contain DHA (Docosahexaenoic Acid) and EPA (Eicosapentaenoic Acid).
Minimum recommended:
● 900-1000mg/day of DHA and 500-600mg/day of EPA
● Fish oil can also come from algae, meaning algae-based Omega-3 also works
Curcumin (Turmeric)
● Originally shown to not be effective, but possibly not absorbed properly because needs
to be emulsified with fats
● Specific types of Turmeric seem to work while others don’t
○ Theracurmin: better absorbed nanoparticle form of curcumin that delayed
amyloid accumulation in the brain according to some studies
Takeaways:
● The majority can get nutrients from the whole food diet, but in up to 40% of cases,
vitamin and nutrient supplements can be great for brain health.
● Many other supplements could work, but currently, Vitamin D and B, Omega-3, and
Curcumin have the greatest evidence of being effective.

Thank you for giving us all of the information. My mom is 97-year-old and in good health but she does have sundown syndrome. I am trying to learn everything I can to help her with this issue.

I’m having a hard time finding an omega 3 with the dosing you recommended. Everything has more EPA than DHA. Is more better? The one I found has 2400 mg DHA and 1800 EPA. Would that work? I have 3 of the APoe4 genes, female, post menopausal and 64yrs old. I’m wanting to do all I can to negate my gene defect for Alzheimer’s disease. Thank you. Any advice would be so appreciated. Also what dosage would you recommend for the theracurcumin?
