Did you know that research has found various nutritional, hormonal, and environmental imbalances may contribute to anxiety? While anxiety can have many causes, taking a deeper look at these underlying factors may help you better understand anxiety. Below, we explore some of the current findings related to anxiety and discuss how a comprehensive approach may offer support using natural therapies and individualized care.
Nutritional Factors and Anxiety
Vitamin B12, Homocysteine, and Folate
A recent study found that elevated homocysteine levels were linked to a higher risk of depression and generalized anxiety disorder, with vitamin B12 deficiency contributing to these imbalances [2019]. While this does not prove causation, it suggests that nutritional pathways may be important in some forms of anxiety. Vitamin B12, along with folate, helps regulate homocysteine, a substance that may affect blood vessels and the nervous system.
Our clinic can complete a comprehensive nutritional panel to assess your vitamin B12, folate, and homocysteine levels. Balancing these nutrients may be one piece of a larger plan for improving anxiety.
Vitamin D
Studies have shown that lower vitamin D levels may be associated with a greater risk of anxiety [2020]. Meanwhile, research also found that vitamin D supplementation appeared to improve anxiety symptoms in those with vitamin D deficiency, though the same effect was not seen for depression [2020]. Though more data are needed, ensuring adequate vitamin D could be part of a holistic strategy for anxiety.
Zinc
Zinc is another nutrient that may be involved in anxiety regulation. A systematic review of human studies reported that individuals with anxiety tended to have lower serum zinc levels than those without anxiety [2024].
If tests show a zinc deficiency, dietary changes or careful supplementation could help support healthy zinc levels.
Environmental Factors
Lead
Evidence has found that elevated blood lead levels are linked to increased odds of both major depression and panic disorder [2009]. Lead exposure can stem from sources like old paint, certain workplaces, or contaminated soil. Testing for heavy metals can help determine whether lead or other metals are contributing to anxiety. Reducing exposure and supporting the body’s natural detoxification processes may be part of an individualized plan.
Hormonal Factors
Thyroid Hormones
Imbalances in thyroid hormones may also affect anxiety. In one study, individuals with panic disorder who had higher thyroid-stimulating hormone (TSH) levels experienced more severe panic attacks [2005]. Similarly, low levels of free thyroxine correlated with elevated anxiety.
If thyroid levels are off, our clinic can help screen for thyroid imbalances as part of a broader anxiety workup. Balancing thyroid hormones may support better mood regulation.
Natural Therapies and Lifestyle Considerations
After identifying any nutritional, hormonal, metabolic, or environmental imbalances, a personalized plan can be created. Possible strategies include:
Dietary Adjustments: Prioritizing nutrient-dense foods to correct any deficits in vitamin B12, folate, zinc and other nutrients.
Nutrient Supplementation: In cases of documented deficiency, supplementation may be recommended to help restore proper levels of nutrients.
Stress Management: Techniques such as mindfulness, meditation, or exercises may reduce anxiety triggers, especially when combined with appropriate nutritional support.
Heavy Metal Reduction: If tests suggest lead or other toxic elements are involved, targeted methods can be used to limit exposure and support detoxification.
Conclusion
Anxiety is a multi-faceted condition that may stem from numerous influences, including nutrient deficiencies, hormonal shifts, environmental toxins, and inflammatory processes. Before starting any treatment, it can be helpful to complete thorough testing to pinpoint which factors apply to your unique situation.
At our clinic, we use personalized ranges to interpret blood work, tailored specifically to each patient and their unique context. Standard blood ranges often lack customization and may not account for individual health needs. By focusing on precise targets, we aim to support specific conditions. Research suggests that certain conditions tend to improve quicker at certain nutritional blood target levels. Similarly, optimal hormone levels are typically found within a narrow, specific range of the standard reference values, ensuring better balance and well-being.
If you’ve been struggling with anxiety, identifying and addressing these underlying factors may be a valuable part of your journey. Naturopathic support can combine diet, lifestyle changes, and evidence-based natural therapies to create a holistic, individualized plan. Feel free to reach out and book a consultation; we’re here to help you navigate the path toward calmer and more balanced living.
