Quick Answer
Nutrients commonly studied for nervous system health include omega-3 fatty acids, magnesium, B vitamins, vitamin D, probiotics, L-theanine, and adaptogenic herbs such as ashwagandha. The right supplement depends on your diet, health history, medications, symptoms, and whether you have a documented deficiency. Supplements should complement-not replace-medical care, adequate sleep, nutrition, movement, and other strategies that support nervous system health.
Nutritional support is one part of a comprehensive approach to nervous system health. Learn how neurofeedback works and how it may help improve brain regulation and resilience.
Why People Look for Nervous System Support
People often look for ways to support their nervous system when experiencing prolonged stress, difficulty sleeping, fatigue, trouble concentrating, or feeling persistently overwhelmed. These symptoms can have many possible causes, so supplements shouldn’t be used as a substitute for proper evaluation when symptoms are persistent, severe, or unexplained.
This information may be especially helpful if you are experiencing:
- Chronic stress or prolonged periods of high stress
- Anxiety or persistent feelings of being overwhelmed
- Brain fog or difficulty concentrating
- Fatigue or low energy levels
- Trouble falling asleep or staying asleep
- Nervous system dysregulation or feeling “stuck” in survival mode
- Recovery after prolonged stress or burnout
- Looking for ways to support long-term brain and nervous system health
Depending on your symptoms and goals, different neurofeedback programs may be appropriate for children, adults, high-performance professionals, and older adults.

Important: Supplements are not appropriate for everyone. Individual needs can vary based on diet, medications, health conditions and other factors. Talk with a qualified healthcare professional before starting a new supplement.
The autonomic nervous system (ANS) controls vital functions such as heart rate, digestion, respiratory rate, and the body’s response to stress. It plays a central role in how we handle daily challenges, regulate energy, and maintain emotional well-being. When this system becomes imbalanced due to chronic stress, poor nutrition, or lack of rest, the effects can ripple through nearly every area of health.
Supporting the nervous system often involves a combination of healthy lifestyle habits, proper nutrition, and personalized care. In addition to targeted supplements, therapies such as neurofeedback may help support healthier nervous system regulation by promoting more balanced brain activity.
In this guide, we’ll explore seven supplements that have been studied for their potential to support nervous system health and promote balance, resilience, and overall well-being.
1. Omega-3 Fatty Acids: Tackling Inflammation, Supporting the ANS
Source: Fish oil, flaxseed oil, chia seeds.
Research: Beyond their recognized cardiovascular benefits, omega-3 fatty acids have been explored for their anti-inflammatory effects. As inflammation disrupts ANS balance, these fatty acids act as natural soothers, tempering inflammatory responses and improving resilience. They have the potential to modulate the ANS reaction to stress. [Swanson et al., 2012]
Dosage: The American Heart Association recommends 1-2 servings of fatty fish per week. If using supplements, common recommendations are around 1,000 mg to 2,000 mg combined EPA and DHA per day.*

2. Probiotics: Gut Health and ANS Communication
Source: Fermented foods (yogurt, kefir), probiotic supplements.
Research: Probiotics, known for promoting gut health, may influence the communication between the gut and the brain, potentially aiding in ANS equilibrium. [Bravo et al., 2011]
Dosage: Dosages may range from 1 billion to 100 billion CFUs per day. Choose a product with a variety of strains and a high number of colony-forming units.*

3. Adaptogens: Stress Response Modulation
Examples: Ashwagandha, Holy Basil.
Research: Adaptogens like Ashwagandha, and Holy Basil are known for modulating the stress response—a crucial aspect in ANS balance. [Panossian and Wikman, 2010]
Dosage: Adaptogenic herbs can vary. For example, Ashwagandha doses typically range from 300 mg to 600 mg per day.*

4. Magnesium: The Unsung Hero in ANS Regulation
Source: Nuts, seeds, leafy greens, magnesium supplements.
Research: Often overlooked, magnesium plays a vital role in physiological processes. Its deficiency has been linked to heightened sympathetic nervous system activity, making magnesium supplementation crucial for ANS balance. [Boyle et al., 2017]
Dosage: Magnesium supplements may be taken at doses of 300 mg to 600 mg per day.*
Not Sure Which Approach Is Right for You?
Nervous system health is influenced by much more than a single supplement. Nutrition, sleep, stress, medications, health conditions, and patterns of brain activity can all play a role. At NeuroLogic Seattle, we take an individualized approach to understanding your symptoms and identifying options that may support your overall brain and nervous system health.
5. L-Theanine: Calming Effects on Neurotransmitters
Source: Found in tea leaves (especially green tea).
Research: L-Theanine, found in tea leaves, has been investigated for its calming effects and influence on neurotransmitters, contributing to ANS stability. [Kimura et al., 2007]
Related: Learn more about GABA and its role in the brain’s calming processes.
Dosage: Studies often use doses ranging from 100 mg to 400 mg per day.*

6. Vitamin D: Beyond Bone Health
Source: Sun exposure, fatty fish, fortified foods, vitamin D supplements.
Research: Vitamin D deficiency has been associated with ANS dysfunction. Maintaining adequate levels is crucial for overall health, including ANS function. [Kesby et al., 2011]
Dosage: The Recommended Dietary Allowance (RDA) for vitamin D varies by age and gender. For adults, it’s around 600 IU (15 mcg) per day. Higher doses of 2,000-4,000 IU or more per day, may be recommended for individuals with deficiencies or those living in northern latitude cities such as Seattle.*

7. B Vitamins: Essential for Nerve Function and Energy Production
Source: Meat, fish, dairy products, eggs, legumes, B complex supplements.
Research: B vitamins are crucial for maintaining nerve function, energy production, and overall nervous system health. Deficiencies in B vitamins (common with vegan diets or those with MTHFR mutations) can lead to neurological issues and disrupt ANS balance. Ensuring an adequate intake of B vitamins through diet or supplementation is essential for supporting optimal nervous system function. [Gropper et al., 2017]
Dosage: Dosages of B vitamins can vary based on individual needs and health conditions. A balanced diet rich in B vitamin sources is recommended, along with supplementation if needed.
