Why Serotonin Levels Matter More for Women: A Guide to Balance
Serotonin - The Happy “Hormone”
Serotonin is not a hormone; it is a neurotransmitter, a chemical messenger that helps transmit signals in the brain and throughout the body. However, serotonin does influence hormonal functions and is often colloquially referred to as a "happy hormone" because of its critical role in regulating mood, sleep, appetite, pain and overall mental well-being.
Its impact is particularly significant for women, who experience unique challenges due to hormonal fluctuations and differences in brain chemistry. Research shows that gender differences in serotonin levels can influence how men and women respond to stress, depression, and anxiety (Bale & Epperson, 2015). Interestingly, studies suggest that while married men tend to live longer than single men, single women outlive their married counterparts (Gove et al., 1983). This raises questions about the intricate connection between mental health, gender roles, and emotional well-being.
In his groundbreaking book, Unleash the Power of the Female Brain, Dr. Daniel Amen dives deep into the biological and emotional differences between male and female brains, offering actionable strategies for women to achieve mental clarity, emotional balance, and greater strength. Let’s explore how serotonin plays a pivotal role in this journey.
Understanding Serotonin Levels in Women
Research highlights that serotonin synthesis occurs at a lower rate in women compared to men, potentially making women more susceptible to mood disorders like depression and anxiety (Young, 2007). Hormonal shifts—such as those experienced during menstruation, pregnancy, and menopause—can further impact serotonin levels. These fluctuations underline why women may experience mood swings or heightened emotional sensitivity during these phases.
As Dr. Amen explains in Unleash the Power of the Female Brain, the female brain is uniquely wired for empathy, connection, and multitasking but also requires careful nurturing to counterbalance the effects of lower serotonin levels. Understanding these gender-specific differences is the first step toward addressing mental health disparities and unlocking the full potential of the female brain.
Symptoms of Serotonin Deficiency in Females
Mood Swings: Sudden shifts in mood without apparent triggers.
Negative Thoughts and Behaviours: Tendency to get stuck in the loop of negative thoughts and behaviours.
Anxiety: Persistent worry or fear that feels overwhelming.
Depression: Feelings of sadness, hopelessness, or low energy.
Sleep Disturbances: Trouble falling or staying asleep.
Food Cravings: Especially for carbohydrates, as the body seeks to boost serotonin levels naturally (Michaud et al., 1990).
Dr. Amen’s book provides further insights into how these symptoms relate to the overall function of the female brain and offers practical tools to overcome them.
Natural Ways to Increase Serotonin
Fortunately, there are effective ways to naturally enhance serotonin levels and support mental health. These strategies are aligned with the actionable steps highlighted in Unleash the Power of the Female Brain.
1. Dietary Changes
Incorporating foods rich in tryptophan, an amino acid essential for serotonin production, is a powerful first step. Foods like turkey, salmon, eggs, nuts, and seeds can help boost serotonin levels.
About 90% of the body’s serotonin is produced in the gut, primarily by enterochromaffin cells in the gastrointestinal (GI) tract (Yano et al., 2015).
Serotonin helps regulate:
Gut motility (how food moves through the digestive system).
The gut-brain axis, which influences mood, appetite, and overall well-being.
The gut's role in serotonin production means dietary choices directly impact serotonin levels and, by extension, gut health.

Additionally, supplements like 5-HTP (5-Hydroxytryptophan) can directly support serotonin synthesis. A complex supplement combining 5-HTP with valerian root, magnesium, and vitamin B6 is particularly beneficial, as it not only promotes serotonin production but also enhances sleep quality.
Dr. Amen emphasizes the importance of nourishing the brain through a balanced diet, as it directly affects mood, focus, and overall resilience.
2. Regular Exercise
Exercise is a proven serotonin booster, benefiting both mental and physical health. Interestingly, men naturally produce more testosterone, which indirectly supports higher serotonin levels. For women, regular physical activity not only enhances serotonin production but also increases testosterone levels, further amplifying this effect (Zouhal et al., 2020). Activities like brisk walking, yoga, or strength training can be particularly effective.
Dr. Amen explains further how integrating exercise into your routine can rewire the female brain for greater resilience and focus.
3. Sunlight Exposure
Natural sunlight plays a vital role in serotonin synthesis. Spending time outdoors, especially in the morning, can help regulate circadian rhythms and improve mood. Aim for at least 15-20 minutes of sunlight exposure daily to reap these benefits. For those in regions with limited sunlight, light therapy lamps can be a practical alternative.
As highlighted in Unleash the Power of the Female Brain, optimizing your environment—including exposure to natural light—has profound effects on mood and brain health.
Final Thoughts
Maintaining balanced serotonin levels is crucial for women’s mental and emotional well-being. From biological differences to the pressures of modern life, women face unique challenges that make serotonin even more significant for their health. By incorporating dietary changes, engaging in regular exercise, and embracing sunlight exposure, women can take actionable steps toward greater mental resilience.
A 2008 journal article titled “Women Seek Help, Men Die” highlights that men are four times more likely to kill themselves than women are.
Seeking help is the strength of the female brain.
