Best Brain Health Supplements: What Research Shows
The brain relies on nutrients that support mitochondrial energy, reduce oxidative stress, and promote healthy neurotransmitter function. Certain nutrients and supplements have been studied for their potential roles in supporting mitochondrial function, reducing oxidative stress, and maintaining cognitive performance with aging.*

The brain contains approximately 100 billion neurons with trillions of connections that control everything from basic bodily functions to complex thinking, memory, and emotions. Supporting brain health requires a foundation of quality sleep, regular exercise, stress management, and proper nutrition.
Essential Insights
- Omega-3 fatty acids (especially DHA) have the strongest evidence for supporting brain and cognitive health.
- Phosphatidylserine, curcumin, and acetyl-L-carnitine have been studied for memory and age-related cognitive concerns.
- CoQ10 supports mitochondrial energy production in brain cells.
- Benefits are often modest and vary by individual; no supplement is a miracle cure.
- Lifestyle factors (sleep, exercise, diet) remain the foundation of brain health.
What the Research Shows
Omega-3 fatty acids, particularly DHA and EPA from fish oil, have the most consistent research support. Meta-analyses show they may help maintain cognitive function and support brain structure, especially in older adults.
Phosphatidylserine has been studied for its potential to support memory and attention. Curcumin (from turmeric) shows anti-inflammatory and antioxidant properties that may benefit brain health, though results are mixed.
While some nutrients such as omega-3 fatty acids show more consistent support in research, many studies on other supplements are small, short in duration, or yield mixed results. Larger, well-controlled human trials are still needed to confirm consistent cognitive benefits across broader populations.
Key Studies
- NIH/PubMed — Dyall, 2015 (Review) — Omega-3 fatty acids support brain structure and cognitive function, particularly DHA. NIH/PubMed — Dyall, 2015
- NIH/PubMed — Glade & Smith, 2015 — Phosphatidylserine may support cognitive function and attention in older adults. NIH/PubMed — Glade & Smith, 2015
- NIH/PubMed — Small et al., 2018 — Curcumin supplementation showed potential cognitive benefits in older adults. NIH/PubMed — Small et al., 2018
Evidence Strength: Moderate for Omega-3s / Preliminary to Mixed for Most Others
“The brain is incredibly complex and resilient. Supporting it with quality nutrition, sleep, exercise, and stress management remains the foundation. Supplements like omega-3s, phosphatidylserine, and others may offer additional support for some people, but they are never a substitute for a healthy lifestyle.”

Frequently Asked Questions
What is the best supplement for brain health?
Omega-3 fatty acids (especially DHA) have the most consistent research support. Other nutrients like phosphatidylserine and curcumin show promise but with more mixed results.
Do brain supplements really work?
Some may offer modest support, particularly when addressing deficiencies or in older adults. Benefits vary widely by individual, and no supplement dramatically improves cognition in healthy people.
Is it safe to take multiple brain supplements?
Many are generally well tolerated, but combining several should be done carefully. Consult a healthcare provider, especially if you take medications.
