Nutrition
Nutrition plays a key role in supporting brain health within the Dale Bredesen protocol. A well-balanced approach to eating helps stabilize blood sugar levels, improve energy, and provide the nutrients needed to keep the brain functioning at its best. The goal is to fuel the body while reducing inflammation and oxidative stress, two factors linked to cognitive decline.
- Fasting window: A daily fasting window of at least 12 hours helps shift the body into mild ketosis, a state where fat is used for energy instead of glucose. This change supports brain function and may help reduce inflammation and age-related damage.
- Blood sugar targets: The Bredesen protocol diet encourages maintaining fasting glucose levels under 90 mg/dL and HbA1c levels below 5.6%. These targets are linked to improved metabolic control and reduced risk of insulin resistance.
- Insulin control: One of the key goals is to keep fasting insulin levels around 4.5 or lower. This helps improve insulin sensitivity and allows the body to burn fat more efficiently, which supports brain fuel stability.
- Meal focus: Meals are centered on non-starchy vegetables, healthy fats (like avocados, olive oil, and nuts), and small portions of clean protein. This helps lower inflammation while supplying the brain with essential nutrients.
- Elimination of processed foods: The plan avoids sugars, grains, and processed foods that can increase oxidative stress. These foods are often linked to inflammation, which may negatively affect brain health over time.
- Nutrient density: Meals are designed to provide fiber, antioxidants, and essential micronutrients. These components help reduce inflammation, support detoxification, and give the brain the tools it needs to perform well.
This style of eating is a central part of the Bredesen protocol meal plan. It’s designed to give the brain consistent, clean energy while lowering the metabolic stressors that can speed up cognitive decline.

Exercise
Physical activity is more than just a lifestyle habit in the Bredesen protocol. It plays a supporting role in protecting the brain, improving mood, and enhancing overall metabolic health. The focus isn’t just on burning calories, but on helping the body function better in ways that support long-term cognitive performance.
- Aerobic movement: Fast-paced walking, light jogging, or other forms of cardio help increase cerebral blood flow, which supports oxygen delivery and waste removal in the brain. These activities also help activate key growth factors that promote neuron health.
- Resistance training: Lifting weights or using resistance bands strengthens muscles, improves insulin response, and promotes the release of hormones that support brain and metabolic function. This also helps counteract age-related muscle loss.
- Exercise frequency: Moving for at least 30 minutes a day, five times per week, helps support cardiovascular and cognitive health. The goal is to move with enough intensity to raise the heart rate, even briefly.
- Strength schedule: Strength training is recommended two to three times weekly. These sessions help maintain lean body mass, improve bone density, and reduce risk of injury.
- Mind-body activities: Practices like yoga, Tai Chi, or guided movement sessions are encouraged to improve balance, coordination, and focus, while also helping to manage stress and support relaxation.
- Daily movement: Beyond structured workouts, staying active during the day helps prevent stiffness, boosts circulation, and counters the negative effects of prolonged sitting. Even short walks or stretching breaks can make a difference.
- Additional benefits: Regular physical activity also supports better sleep, improved mood, and balanced hormone levels, all of which contribute to a stronger and more resilient mind.
Exercise plays an important role in the overall success of the Dr Bredesen Protocol, helping support brain health through improved circulation, hormone balance, and energy regulation.

Supplementation
Products that are part of the Bredesen protocol supplement list support areas where diet alone may not be enough. These additions help correct deficiencies, support brain function, and improve overall health based on individual lab results and needs.
- Omega-3 fish oil: This essential fatty acid supports the structure of brain cell membranes and promotes efficient communication between neurons. It also plays a role in reducing inflammation, protecting against cognitive decline, and supporting heart health, making it one of the most commonly used supplements in the protocol.
- Vitamin D3 +K2: This fat-soluble vitamin supports brain health, immune regulation, and bone strength. Many people have low levels of Vitamin D, and correcting it may improve mood, sleep quality, and cognitive clarity.
- B vitamins (B6, B12, Folate): These vitamins are essential for lowering homocysteine, a marker linked to cognitive risk. They also support red blood cell formation, nerve function, and energy metabolism. Supplementing B vitamins is especially helpful for those with MTHFR variants or elevated inflammation.
- Magnesium: This mineral is involved in hundreds of biological reactions, including those related to muscle relaxation, nerve signaling, and glucose regulation. It can also help reduce anxiety, promote calm before bed, and improve insulin sensitivity.
- Zinc: Zinc is important for immune defense, wound healing, and brain signaling. It may help reduce oxidative stress and inflammation, and is especially important for older adults or those with digestive issues that impact absorption.
- Vitamin C and E: Both vitamins act as powerful antioxidants. Vitamin C helps regenerate other antioxidants and supports immune health, while Vitamin E protects cell membranes from damage. Together, they provide defense against oxidative stress in the brain.
- Coenzyme Q10: This compound is key for energy production inside cells, especially in the heart and brain. It supports mitochondrial function and may help reduce mental and physical fatigue, particularly in those taking statins or under chronic stress.
- Curcumin and Resveratrol: These plant-based compounds help reduce inflammation and may interfere with the buildup of harmful proteins like amyloid-beta. They also support cellular health and provide antioxidant effects that benefit overall aging.
- Probiotics: A healthy gut microbiome supports digestion, nutrient absorption, immune balance, and even mood regulation. Probiotic supplements may help reduce inflammation and promote better communication between the gut and brain.
- N-acetylcysteine (NAC) or Glutathione: Both support detoxification by replenishing the body’s master antioxidant, glutathione. These are often used to help the liver process environmental toxins and reduce oxidative damage to brain cells.
- Melatonin: More than just a sleep aid, melatonin also acts as a brain antioxidant and supports circadian rhythm alignment. In the protocol, it’s often used to improve sleep quality and support nighttime recovery.
- Berberine or Chromium: These are helpful for individuals with blood sugar regulation issues. Berberine supports insulin sensitivity and may help lower fasting glucose, while chromium improves glucose metabolism and supports balanced energy levels.
- Alpha-lipoic acid or NAD boosters: These supplements may be used in individuals under oxidative stress or fatigue. Alpha-lipoic acid supports mitochondrial health and antioxidant defense, while NAD boosters help improve cellular energy production and repair mechanisms.
Supplementation is not one-size-fits-all. The Bredesen approach uses lab testing and health history to guide decisions, with the goal of reducing or adjusting supplements as health improves over time.

Sleep Optimization
Restful sleep plays a quiet but essential role in brain health. It’s during sleep that the brain clears out waste, resets hormone levels, and supports memory and mood. Within the Dale Bredesen protocol, sleep is viewed as a powerful support tool for cognitive function and overall wellness.
- Sleep duration: Aiming for 7 to 8 hours of uninterrupted, quality sleep each night allows the brain to complete key cleanup processes and support memory.
- Sleep hygiene: Keeping the bedroom dark, cool, and quiet helps the body wind down naturally. Avoiding screens, bright lights, and Wi-Fi signals at night can also reduce stimulation and improve sleep quality.
- Sleep disorders: Addressing conditions like sleep apnea is important, as poor oxygen levels during the night can increase brain stress. Tools like pulse oximeters and oral devices may be recommended to improve breathing during sleep.
- Supplement support: Melatonin may be used at bedtime to encourage sleep onset. Other natural sleep aids may also be considered if sleep remains disrupted despite other changes.
- Consistent schedule: Going to bed and waking up at the same time every day helps regulate the body’s internal clock. This regularity supports deeper, more restorative sleep.
- Cognitive benefits: Better sleep supports brain detoxification, improves hormone balance, and reduces inflammation, all of which can affect cognitive performance.
Getting high-quality rest is one of the core habits supported by this extensive protocol, helping the brain recharge and recover each night for better performance the next day.

Stress Reduction
Managing stress is a core part of this protocol, as chronic pressure can interfere with memory, hormone regulation, and overall brain health. Daily practices that promote calm and stability are used to counteract the effects of long-term mental and emotional strain.
- Daily calming practices: Quiet routines such as breathing exercises, journaling, or sitting in silence for a few minutes each morning or night help regulate the nervous system and bring down stress hormone levels gradually.
- Mindfulness and meditation: Practicing mindfulness or meditation for 10 to 20 minutes twice a day may help increase brain resilience, reduce mental clutter, and promote more restful sleep at night.
- Movement-based relaxation: Low-impact exercises like Tai Chi, yoga, or slow stretching not only ease muscle tension but also support better circulation and encourage a steady, relaxed mental state.
- Supportive habits: Activities like walking outdoors, listening to soft music, or engaging in creative hobbies give the brain a break from overthinking and allow space for emotional reset.
- Sleep and screen time: Reducing screen exposure in the evening and keeping schedules manageable helps avoid sensory overload and improves the body’s ability to wind down naturally.
- Supplement support: Nutrients such as magnesium or herbal supplements like L-theanine are sometimes used to help the body relax without causing drowsiness during the day.
- Brain retraining tools: Programs that use sound, breathing, or guided visualization can help shift the brain out of stress-response mode and into a more balanced, recovery-friendly state.
Supporting the body’s stress response through consistent habits can help protect memory, stabilize energy levels, and promote a more relaxed and focused daily rhythm.

Brain Stimulation & Cognitive Training
Mental activity is just as important as physical movement when it comes to brain health. As part of this plan, regular cognitive engagement is encouraged to keep the brain learning, adapting, and building new connections over time.
- Mental workouts: Brain training activities that target memory, attention, and problem-solving are recommended a few times each week. These exercises keep the brain alert and may help slow cognitive decline when practiced consistently.
- Learning new skills: Trying something unfamiliar, such as a new language, a musical instrument, or even a new recipe, helps the brain adapt and build fresh neural pathways. These types of activities improve both learning and recall.
- Purposeful daily activity: Reading, doing puzzles, or playing mentally stimulating games can be enjoyable ways to stay mentally active. These simple habits encourage daily focus and attention.
- Creative challenges: Activities like painting, writing, sculpting, or even gardening give the brain new tasks to solve and explore. Creative thinking supports mental flexibility and long-term cognitive resilience.
- Group engagement: Joining a class, book club, or discussion group helps sharpen thinking and also builds a sense of connection. These group activities promote better focus while reducing feelings of isolation.
- Listening and rhythm: Listening to music or learning to play an instrument stimulates multiple areas of the brain. Repeating rhythms or musical patterns also helps train memory and coordination.
- Social interaction: Having regular conversations, attending events, or staying in touch with friends supports brain health. Social contact improves emotional balance and keeps thinking skills sharp.
Keeping the mind active through daily challenges, learning, and social connection can make a lasting difference in how well the brain performs over time.

Detoxification and Avoiding Toxins
Toxins can build up in the body from everyday sources like food, water, air, and household products. In this protocol, there is a strong emphasis on limiting these exposures while helping the body clear out anything that may interfere with brain or metabolic function.
- Clean water: Using filtered or purified water helps reduce intake of heavy metals, chlorine, and other potential contaminants that may build up over time.
- Air quality: Keeping indoor air clean by using air purifiers, ventilating spaces, and avoiding synthetic fragrances helps lower exposure to airborne irritants and toxins.
- Low-toxin household products: Switching to fragrance-free, non-toxic cleaning and personal care products reduces contact with harmful chemicals that may be absorbed through the skin or inhaled.
- Heavy metal screening: Testing for mercury, lead, or other heavy metals may be recommended. If elevated, detox strategies can be used under supervision to help remove them gradually from the body.
- Mold awareness: Mold exposure in homes or workplaces can affect brain function and immune health. Identifying and removing mold sources is a key step for many individuals.
- Healthy sweating: Regular physical activity and practices like sauna use support the body’s natural detox systems by encouraging sweat, which can help release stored toxins.
- Support for detox pathways: You can use specific nutrients or supplements to support liver function and detoxification. These may include antioxidants or herbs that aid elimination.
- Supplement routine: Detox-focused supplements like glutathione or binders are sometimes used to help the body manage existing toxic load. These are typically taken under medical guidance.
Supporting the body’s ability to detox and reducing daily toxin exposure can protect long-term brain health and support the systems that help the body stay balanced.
