Anxiety and depression are among the most common health challenges in the modern world and their prevalence continues to rise. Millions of people struggle with persistent low mood, fatigue, irritability, or worry, often without clear explanations or lasting relief.1 While these conditions are influenced by many psychological and social factors, two of the most overlooked contributors are hormonal imbalances and nutrient deficiencies.
Both play a critical role in mood regulation, stress resilience and cognitive health and disruptions in either system can intensify symptoms of anxiety and depression. From the perspective of naturopathic medicine, understanding these root causes is essential to building a comprehensive and sustainable plan for mental well-being.
The Overlooked Link Between Hormones, Nutrients and Mental Health
Hormones are chemical messengers that regulate essential functions such as energy production, sleep, mood and appetite. When these messengers fall out of balance, the impact on emotional well-being can be profound. A naturopathic doctor is trained to evaluate these connections, considering how stress, diet and lifestyle contribute to imbalances.
Cortisol, known as the stress hormone, is a central player. In short bursts, cortisol helps the body respond to challenges. But chronically elevated cortisol levels—often the result of poor sleep, chronic stress, or systemic inflammation—can impair serotonin production, increase inflammation in the brain and leave individuals feeling anxious or depressed.2
Estrogen also has a strong relationship with mood. It helps regulate serotonin and dopamine, neurotransmitters essential for feelings of calmness and motivation. Low estrogen levels, which commonly occur during perimenopause and menopause, are linked with depression, irritability and anxiety.3
Progesterone provides a natural calming effect on the brain. When progesterone is low, anxiety, irritability and sleep disturbances are common. Imbalances between estrogen and progesterone—often referred to as estrogen dominance—may worsen premenstrual mood swings or postnatal depression.
Thyroid hormones further illustrate the connection. Hypothyroidism, or underactive thyroid function, slows metabolism and energy production. Many patients with low thyroid function report fatigue, hopelessness and difficulty concentrating. Because thyroid dysfunction is more common in women, it is an important consideration in female mental health and is regularly evaluated in naturopathy.
Managing inflammation is core to naturopathy’s holistic approach to prevention and treatment of mood disorders
Even when hormone balance is optimal, inadequate nutrition can still undermine emotional well-being. Several nutrients are essential for the synthesis of neurotransmitters and for regulating inflammation, both of which influence mental health. A naturopath often investigates nutritional status when patients present with anxiety or depression.
Nutrient Deficiencies and Their Impact on Mental Well-Being
Magnesium is sometimes referred to as the relaxation mineral. It supports over 300 biochemical reactions, including the production of GABA, a neurotransmitter that calms the nervous system.4 Deficiency is associated with anxiety, heightened stress responses and poor sleep. Leafy greens, nuts, seeds, legumes and avocados are rich sources, but many people require supplementation for therapeutic benefit.
B vitamins, especially B6, folate (B9) and B12, are critical for the production of serotonin, dopamine and other neurotransmitters. Deficiency in these vitamins can cause fatigue, irritability, brain fog and low mood. Because stress, medications and poor diet can quickly deplete B vitamin levels, supplementation is often necessary in those with chronic anxiety or depression.5
Omega-3 fatty acids, found in fatty fish and some plant sources, are structural components of brain cell membranes. They regulate inflammation and enhance neurotransmitter function. Low levels of omega-3s have been consistently linked to depression, poor concentration and heightened anxiety. Supplementation with fish oil or algae-based products has been shown in research to improve symptoms of depression and support cognitive function.6
Serotonin, sometimes called the “happy hormone,” is central to mood regulation. Adequate serotonin levels foster feelings of calmness and satisfaction, while low levels are linked with depression, anxiety, social withdrawal and even digestive concerns. Interestingly, about 95 percent of serotonin is produced in the gastrointestinal tract, underscoring the powerful connection between gut health and mental health—a connection that naturopathic medicine emphasizes.7
Symptoms of low serotonin include sleep disturbances, loss of appetite, difficulty concentrating, chronic unexplained pain and digestive issues such as irritable bowel syndrome. Because serotonin synthesis depends on the amino acid tryptophan, foods such as turkey, salmon, pumpkin seeds and tofu can help support its production. Healthy gut bacteria are also essential, making probiotic-rich foods and anti-inflammatory diets important for long-term mood stability.

Increasing research shows that chronic inflammation is a significant factor in depression.8 Elevated levels of inflammatory markers such as C-reactive protein are commonly found in people with depressive symptoms. Over time, inflammation can impair brain function and may even contribute to neurodegenerative conditions. Chronic stress further compounds this process by altering cortisol rhythms and suppressing immune regulation.
Because of this, natural anti-inflammatory strategies—including diets rich in colorful vegetables, omega-3 fatty acids, green tea and spices such as turmeric—are valuable for supporting both mental and physical health. Many of these strategies are core to naturopathy’s holistic approach to prevention and treatment.
Lifestyle and Natural Strategies for Mental Health Balance
Supporting mental health through nutrition and hormonal balance involves several interconnected lifestyle strategies. A nutrient-dense diet that includes magnesium, B vitamins, omega-3 fatty acids and tryptophan-rich proteins lays the foundation for mood stability and neurotransmitter production.
Equally important is maintaining gut health by incorporating probiotic foods such as kefir, sauerkraut and kombucha, along with a variety of anti-inflammatory vegetables. Stress management practices, including yoga, meditation, breathwork, or spending time in nature, help calm the nervous system and regulate cortisol levels.
Prioritizing sleep is another essential factor, as seven to nine hours of deep rest each night is required for hormone regulation and optimal brain function. Regular physical activity, particularly steady-state aerobic exercise, has also been shown to enhance serotonin production and ease depressive symptoms.
In some cases, supplementation may provide additional support, especially when guided by a naturopathic doctor. Magnesium, high-quality B vitamins, omega-3 fatty acids and adaptogenic herbs such as rhodiola and ashwagandha can be valuable tools when integrated into a personalized care plan.
From the perspective of naturopathic medicine, understanding the root causes of anxiety and depression is essential to building a comprehensive and sustainable plan for mental well-being
Depression and anxiety rarely arise from a single cause. Instead, they reflect the interplay between psychological, physiological and environmental factors. While medications can provide relief for some, they are often insufficient on their own. Addressing hormonal health, correcting nutrient deficiencies, reducing inflammation and supporting the nervous system provide a more comprehensive and sustainable path to recovery.
