17 Best Supplements to Reduce Cortisol Levels in 2025
Top 17 Supplements to Reduce Cortisol Levels Naturally in 2025 for Stress Relief & Adrenal Support
In our modern, fast-paced world, chronic stress has become an all-too-common experience. One of the body’s primary responses to stress is the release of cortisol, a hormone produced by the adrenal glands.
While cortisol plays a vital role in various physiological functions, persistently elevated levels can lead to a host of health issues, including weight gain, sleep disturbances, impaired immune function, and mood disorders.
Fortunately, a combination of lifestyle modifications and targeted supplementation can help manage cortisol levels effectively.
In this comprehensive guide, we’ll explore 17 of the most effective supplements to reduce cortisol in 2025, backed by scientific research and expert recommendations.
Understanding Cortisol: The Stress Hormone
Cortisol is often referred to as the “stress hormone” because it’s released in response to stress and low blood-glucose concentration.
It helps regulate metabolism, reduce inflammation, and control blood sugar levels. However, chronic stress can lead to prolonged cortisol elevation, which may contribute to:
- Increased abdominal fat
- Insomnia
- Anxiety and depression
- High blood pressure
- Weakened immune response
Managing cortisol levels is crucial for overall health and well-being.
Top 17 Supplements to Lower Cortisol
1. Ashwagandha
- Ashwagandha is an adaptogenic herb traditionally used in Ayurvedic medicine. Studies have shown that it can reduce cortisol levels by 11–33%, improving stress resilience and promoting relaxation. Standardized extracts like KSM-66 and Sensoril are commonly used in supplements.
2. Magnesium
- Magnesium plays a vital role in over 300 enzymatic reactions in the body, including those that regulate the stress response. Supplementation, particularly with magnesium glycinate, has been associated with reduced cortisol levels and improved sleep quality.
3. Omega-3 Fatty Acids
- Omega-3s, found in fish oil, have anti-inflammatory properties and support brain health. Research indicates that omega-3 supplementation can lower cortisol levels and alleviate symptoms of stress and anxiety.
4. L-Theanine
- An amino acid found in green tea, L-theanine promotes relaxation without drowsiness. It has been shown to reduce cortisol levels and enhance cognitive function, making it beneficial for stress management.
5. Rhodiola Rosea
- Rhodiola is another adaptogen that helps the body adapt to stress. It has been found to lower cortisol levels, reduce fatigue, and improve mental performance under stress.
6. Phosphatidylserine
- This phospholipid is essential for healthy brain function. Supplementation has been linked to reduced cortisol levels, especially after exercise-induced stress, and improved cognitive function.
7. Vitamin C
- Vitamin C is a potent antioxidant that supports adrenal function. Supplementation can help lower cortisol levels, particularly in individuals under high stress.
8. Holy Basil (Tulsi)
- Holy Basil is an adaptogenic herb known for its calming effects. It supports emotional well-being and promotes a balanced stress response, potentially aiding in cortisol regulation.
9. Ginseng
- Ginseng, particularly Panax ginseng, has been shown to modulate the stress response and may help lower cortisol levels. It also supports energy levels and cognitive function.
10. Taurine
- An amino acid that supports the nervous system, taurine has been found to stabilize cortisol levels and improve stress tolerance by promoting relaxation.
11. Chamomile
- Chamomile is well-known for its calming properties. While more research is needed, it may help reduce stress and support lower cortisol levels.
12. St. John’s Wort
- Commonly used for mild to moderate depression, St. John’s Wort may influence cortisol levels by modulating neurotransmitter activity. However, it can interact with various medications, so consultation with a healthcare provider is essential.
13. Vitamin D3
- Vitamin D3 plays a role in mood regulation and immune function. Adequate levels may help modulate the stress response and maintain balanced cortisol levels.
13. B-Complex Vitamins
- B vitamins, including B6, B12, and folic acid, are crucial for energy production and stress management. They support adrenal function and may help regulate cortisol production.
15. Reishi Mushroom
- Reishi is a medicinal mushroom with adaptogenic properties. It may help reduce cortisol levels, support immune function, and promote relaxation.
16. Cordyceps
- Another adaptogenic mushroom, Cordyceps has been shown to enhance energy and stamina. It may also help modulate the stress response and cortisol production.
17. Schisandra Berry
- Schisandra is an adaptogenic berry used in traditional Chinese medicine. It supports adrenal health and may help balance cortisol levels during periods of stress.
Combining Supplements for Optimal Results
Several supplements can be combined for synergistic effects.
For instance, products like Cortisol Manager® by Integrative Therapeutics combine Sensoril® ashwagandha, L-theanine, magnolia bark, and phosphatidylserine to support a balanced cortisol response.
Similarly, multi-ingredient supplements available on the market may include combinations of magnesium, ashwagandha, chamomile, L-theanine, phosphatidylserine, St. John’s Wort, Rhodiola, Vitamin C, and D3 to provide comprehensive stress support.
Lifestyle Strategies to Complement Supplementation
While supplements can be beneficial, they are most effective when combined with healthy lifestyle practices:
- Regular Exercise: Engage in moderate physical activity to reduce stress and lower cortisol levels.
- Mindfulness and Meditation: Practicing mindfulness can help manage stress and promote relaxation.
- Adequate Sleep: Aim for 7–9 hours of quality sleep per night to support hormonal balance.
- Balanced Diet: Consume a nutrient-rich diet, limiting processed foods and sugar.
- Social Support: Maintain strong social connections to buffer against stress.
How to Choose the Right Cortisol-Lowering Supplement in 2025
With so many options on the market, it’s easy to feel overwhelmed when choosing a supplement to help lower cortisol. Here are a few critical factors to consider before making a purchase:
1. Ingredient Quality and Source
Look for brands that use high-quality, clinically studied ingredients. For example:
- Ashwagandha should be standardized (like KSM-66® or Sensoril®).
- Fish oil should be molecularly distilled for purity and potency.
- Mushrooms like Reishi or Cordyceps should be hot water extracted for maximum bioavailability.
2. Third-Party Testing
- Always choose supplements that are third-party tested for purity, potency, and safety. Certification from organizations such as NSF, USP, or ConsumerLab adds credibility.
3. Bioavailability
- Supplements that offer higher absorption rates like liposomal Vitamin C or magnesium glycinate instead of oxide are more effective.
4. Formulation Synergy
- Many cortisol-lowering supplements work better in tandem. A good formulation will include a mix of adaptogens, vitamins, and amino acids that support the HPA (hypothalamic-pituitary-adrenal) axis, the body’s primary stress-response system.
