Chronic stress is a modern epidemic, and elevated cortisol levels are at the heart of the problem. While cortisol is essential for regulating metabolism, immune function, and the body’s stress response, too much of it can lead to anxiety, fatigue, brain fog, and even long-term health issues like weight gain and heart disease.
For those seeking natural ways to lower cortisol, two popular options stand out: Phosphatidylserine and Lemon Balm. But which one is more effective?

What Is Phosphatidylserine?
Phosphatidylserine (PS) is a phospholipid found in cell membranes, particularly in the brain. It plays a crucial role in cognitive function, cell signaling, and stress regulation. Studies suggest that PS can help lower cortisol levels, making it a promising supplement for stress management.
How Phosphatidylserine Reduces Cortisol
Phosphatidylserine works through several mechanisms to help regulate stress and cortisol:
- Blunts Cortisol Response to Stress: PS helps prevent excessive cortisol spikes in response to psychological and physical stressors.
- Supports the Hypothalamic-Pituitary-Adrenal (HPA) Axis: The HPA axis controls stress hormone production, and PS helps regulate its activity.
- Enhances Cognitive Function Under Stress: High cortisol levels impair memory and focus. PS helps counteract this effect.
- Promotes Restful Sleep: Elevated cortisol disrupts sleep patterns, but PS may help restore balance and improve sleep quality.
Scientific Research on Phosphatidylserine for Cortisol Reduction
Numerous studies support PS’s role in reducing cortisol:
- A 1992 study in European Journal of Clinical Pharmacology found that Phosphatidylserine blunted cortisol responses in individuals subjected to stress.
- A 2004 study in Hormone and Metabolic Research showed that daily PS supplementation lowered cortisol levels and improved mood in individuals undergoing intense physical training.
- A 2011 clinical trial concluded that Phosphatidylserine helped reduce stress-related cognitive impairment and prevent memory decline under pressure.
Benefits of Phosphatidylserine for Cortisol Reduction
Phosphatidylserine provides several key benefits for those dealing with high cortisol:
- Reduces cortisol spikes caused by stress
- Enhances focus and cognitive function under pressure
- Improves sleep quality by lowering evening cortisol
- Supports recovery from physical and mental stress
- May improve mood and reduce anxiety
Potential Side Effects of Phosphatidylserine
Phosphatidylserine is generally well-tolerated, but some individuals may experience:
- Mild digestive discomfort
- Insomnia if taken too late in the day
- Potential interactions with blood thinners
What Is Lemon Balm?
Lemon Balm (Melissa officinalis) is an herb in the mint family known for its calming effects. Used for centuries in traditional medicine, Lemon Balm is often taken to relieve anxiety, improve sleep, and promote relaxation.
How Lemon Balm Reduces Cortisol
Lemon Balm helps regulate stress and cortisol levels through the following mechanisms:
- Boosts GABA Activity: GABA is the brain’s primary inhibitory neurotransmitter, responsible for reducing nervous system excitability. Lemon Balm enhances GABA function, promoting relaxation and lowering stress-induced cortisol release.
- Reduces Psychological Stress: Studies show that Lemon Balm can calm the nervous system and lower cortisol levels in response to stress.
- Improves Sleep Quality: Poor sleep increases cortisol levels. Lemon Balm has mild sedative effects that help improve sleep patterns.
- Protects Against Oxidative Stress: Chronic stress causes inflammation, which can contribute to cortisol dysregulation. Lemon Balm has antioxidant properties that help combat this effect.
Scientific Research on Lemon Balm for Cortisol Reduction
Several studies highlight Lemon Balm’s ability to reduce stress and lower cortisol:
- A 2004 study in Psychosomatic Medicine found that Lemon Balm reduced cortisol levels and improved mood in individuals exposed to stress.
- A 2011 study in Journal of Ethnopharmacology found that Lemon Balm enhanced relaxation and reduced stress-related symptoms, including elevated cortisol.
- A 2020 meta-analysis concluded that Lemon Balm is effective in lowering anxiety and stress-induced cortisol surges.
Benefits of Lemon Balm for Cortisol Reduction
Lemon Balm offers multiple advantages for individuals dealing with high cortisol levels:
- Promotes relaxation and mental calmness
- Reduces stress-induced cortisol surges
- Enhances sleep quality and recovery
- Improves mood and emotional resilience
- Supports nervous system balance
Potential Side Effects of Lemon Balm
Lemon Balm is generally safe, but some individuals may experience:
- Mild drowsiness
- Possible interactions with thyroid medication
- Lowered blood pressure (caution for those with hypotension)
Phosphatidylserine vs. Lemon Balm: Which Is More Effective for Reducing Cortisol?
Both Phosphatidylserine and Lemon Balm effectively reduce cortisol, but they work differently:
| Feature | Phosphatidylserine | Lemon Balm |
|---|---|---|
| Primary Mechanism | Blunts cortisol response to stress | Enhances GABA function and nervous system relaxation |
| Best For | Reducing stress-induced cognitive impairment | Relaxation, sleep, and nervous system balance |
| Onset of Effects | 1-2 weeks | 30-60 minutes |
If you’re looking for a scientifically backed supplement that directly reduces cortisol levels and improves cognitive function under stress, Phosphatidylserine is the best choice.
If you prefer a natural, herbal approach that promotes relaxation, reduces stress, and improves sleep, Lemon Balm may be the better option.
Some individuals find that combining both supplements provides a well-rounded approach to stress reduction. As always, consult a healthcare professional before starting any new supplement regimen.
