Top 10 Supplements to Lower Cortisol Naturally
Clinically-Backed
Cortisol, often referred to as the “stress hormone,” plays a crucial role in your body’s response to stress. While cortisol is important for survival, high levels over time can harm your health. This can lead to weight gain, sleep disturbances, a weakened immune system, and even cognitive issues. If you are feeling the effects of stress, finding good supplements to lower cortisol can help your body and mind.


In this comprehensive guide, we’ll explore the top 10 science-backed supplements to reduce cortisol levels naturally. From powerful adaptogens to essential nutrients, these options have demonstrated real results in clinical studies. If you are feeling stressed at work, going through life changes, or dealing with anxiety, there are natural solutions that can help. These solutions can balance your stress response.
Understanding Cortisol: The Stress Hormone's Impact on Your Health
Before diving into supplements to lower cortisol, it’s important to understand what this hormone does and why balance matters. Cortisol is produced by your adrenal glands in response to stress signals from your brain. In healthy amounts, cortisol helps regulate metabolism, reduce inflammation, and control blood pressure
.
Signs of Elevated Cortisol
- Weight gain, especially around the abdomen
- Sleep disturbances and insomnia
- Fatigue and low energy levels
- Mood changes, anxiety, and irritability
- Weakened immune function
- Digestive issues and cravings
- Difficulty concentrating or “brain fog”
- Reduced muscle mass and bone density

Long-Term Health Risks
- Increased risk of anxiety and depression
- Compromised immune function
- Higher blood pressure and heart disease risk
- Insulin resistance and diabetes
- Hormonal imbalances
- Cognitive decline and memory issues
- Disrupted sleep patterns
- Accelerated aging processes
Did you know? Your body’s cortisol levels follow a daily pattern. They are highest in the morning to help you wake up. Then, they gradually decrease throughout the day. Chronic stress disrupts this pattern, keeping cortisol elevated when it should be declining.
