How the Brain Ages
Main Causes of Brain Aging
The brain uses about 20% of the body's oxygen, making it especially prone to age-related changes [2].
Here are the three main drivers of brain aging:
- Oxidative Stress: Because the brain uses so much oxygen, it’s highly exposed to oxidative damage. This happens when reactive oxygen species (ROS) outnumber the body’s antioxidant defenses, leading to cell damage [2].
- Mitochondrial Dysfunction: As mitochondria age, they become less effective. This disrupts calcium ion regulation, which is critical for neural communication and energy production.
- Neuroinflammation: Immune cells like microglia and astrocytes interact in ways that cause inflammation as we age. Chronic inflammation in the brain speeds up cognitive decline and contributes to neurodegenerative diseases [2].
| Aging Factor | How It Affects the Brain | Possible Supplement Solutions |
|---|---|---|
| Oxidative Stress | Leads to cell damage and DNA issues | Antioxidants, NAD⁺ boosters |
| Mitochondrial Dysfunction | Reduces energy and calcium regulation | NMN, Resveratrol |
| Neuroinflammation | Speeds up cognitive decline | Anti-inflammatory compounds |
Brain Health Statistics
By 2060, approximately 98 million Americans over 65 - about 25% of the population - are expected to face cognitive difficulties [2]. Certain lifestyle choices can help slow this decline. For example, higher education, regular physical activity, balanced diets, and moderate alcohol consumption are linked to better brain health. On the other hand, issues like high blood pressure and diabetes can make things worse [2].
These biological processes highlight the importance of exploring supplements that may help counteract these effects. A deeper understanding of these mechanisms can guide targeted approaches, which will be covered in upcoming sections.

4 Brain Health Supplements
Research highlights that certain natural compounds may help maintain brain health. Here’s a look at four supplements and how they contribute.
NMN: Supporting Brain Energy
NMN plays a role in boosting NAD⁺, a molecule critical for energy production in brain cells. It helps maintain mitochondrial function, supports DNA repair, and aids energy metabolism. This makes it particularly helpful in addressing energy-related challenges in aging brain cells.
Resveratrol: Improving Blood Flow and Memory
Resveratrol has shown promise in enhancing cognitive function. In a 24-month clinical trial, taking 75 mg of resveratrol daily led to a 33% improvement in cognitive performance among middle-aged women [3]. These results suggest it can improve blood flow to the brain and support memory.
Spermidine: Promoting Cellular Cleanup
Spermidine helps activate autophagy, the process of clearing out damaged cell components. As we age, this cleanup process slows down, making spermidine especially useful in addressing oxidative stress and maintaining brain cell health.
Fisetin: Clearing Out Aging Cells
Fisetin, known as a senolytic compound, works by removing aging cells that can contribute to inflammation and cognitive decline. This helps support brain health and cognitive function over time.
Each of these supplements targets a specific aspect of brain aging. When paired with a balanced diet and regular exercise, they can provide focused support for maintaining cognitive health.

Supplement Comparison
Here's a comparison to highlight how each supplement works and what it offers.
Side-by-Side Results Table
| Aspect | NMN | Resveratrol | Spermidine | Fisetin |
|---|---|---|---|---|
| Primary Function | Energy production & DNA repair | Blood flow & memory support | Cellular cleanup (autophagy) | Removal of senescent cells |
| Key Benefits | Boosts mitochondrial function, NAD⁺ levels, and energy | Supports cognitive performance, memory, and circulation | Aids cell repair, reduces oxidative stress, and ensures protein quality | Reduces inflammation, protects neurons, and promotes cellular health |
| Safety Profile | Generally well-tolerated | Safe within recommended doses | High safety profile | Well-tolerated |
These supplements take different approaches to promote brain health. NMN focuses on boosting cellular energy, while resveratrol helps improve blood flow and memory. Spermidine aids in cellular cleanup, and fisetin targets inflammation and aging cells. Research suggests combining these supplements with a balanced diet may enhance their effects.
Things to keep in mind when choosing supplements:
- Quality: Opt for pharmaceutical-grade options.
- Timing: Some supplements may work better at specific times of the day.
- Interactions: Always check with your healthcare provider about potential interactions.
- Individual Needs: Consider your age, health, and specific goals.
Always speak with a healthcare professional before starting any new supplements.
Using Brain Supplements
Picking Quality Supplements
Choosing the right brain supplements means focusing on quality and safety. It’s important to look for products that meet strict manufacturing standards and undergo independent testing. This ensures the supplements are both safe and effective. Always check for clear documentation about a product’s purity and potency.
Here are some key things to look for:
- Third-party lab testing: Independent verification of the product’s quality.
- High-grade ingredients: Use of pharmaceutical-grade raw materials.
- Transparent labeling: Clear details about active ingredients and dosages.
- GMP-certified production: Manufactured in facilities that meet Good Manufacturing Practices.
- Ingredient sourcing: Transparency about where the ingredients come from.
Pay close attention to the concentration of active ingredients. For instance, a good NMN supplement should contain pure, stabilized nicotinamide mononucleotide without unnecessary fillers or additives. Once you’ve chosen a quality product, the next step is using it safely.
Safety Guidelines
Even the best supplements need to be used carefully. Before starting any new supplement, talk to your healthcare provider - especially if you have health conditions or take medications.
Here’s how to stay safe:
- Check nutrient levels: Get baseline blood work to measure levels of key nutrients like vitamin B12 or vitamin D.
- Start small: Begin with the lowest effective dose and increase slowly, staying within recommended limits.
- Track changes: Keep a record of all medications and supplements, and watch for any side effects.
Your age and health can also play a role in how much of a supplement you need. For example, older adults may need adjusted doses for certain nutrients.
It’s important to remember that supplements are meant to supplement your diet, not replace it. A diet rich in whole foods should always be the foundation. Regularly review your supplement routine and make changes as needed. If you notice any negative side effects, stop taking the supplement and consult your healthcare provider right away.
Research Updates
Next Research Steps
Cognitive intervention studies have shown potential, but their long-term effectiveness remains unclear. More research is needed to determine how these interventions can provide lasting benefits and identify the best strategies for improving cognitive health. With the aging population growing rapidly, developing timely cognitive-support methods is essential. These gaps highlight the importance of creating treatment approaches tailored to individual needs.
Individual Treatment Plans
Emerging research suggests that personalized supplementation strategies may offer better results than generic approaches. Since individual differences - like genetics and health status - can significantly impact outcomes, customizing supplementation plans could maximize the benefits of interventions such as NMN, resveratrol, spermidine, and fisetin.
| Factor | Impact on Treatment |
|---|---|
| Genetic Profile | APOE genotype affects how effective treatments are |
| Health Status | Diabetes raises dementia risk by 1.5–2 times |
| Age | Mild cognitive impairment (MCI) affects 10–20% of people aged 65 and older |
| Existing Conditions | Current health issues and medications must be considered |
"Combinations of pharmacological and non-pharmacological interventions or combinations of different types of non-pharmacological interventions may be more efficient in improving or preserving cognition." - Chen et al. [1]
Genetics, such as the APOE genotype, and conditions like diabetes - which can double the risk of dementia - emphasize the need for tailored approaches. Multi-domain strategies that integrate targeted supplements with diet, exercise, and cognitive training appear promising for older adults at higher risk [1]. This comprehensive approach focuses on individual needs and overall health, paving the way for more personalized treatment solutions.
