From the Research

Vitamin D supplementation is not recommended as a treatment for seasonal affective disorder (SAD) based on the most recent and highest quality study available 1. Instead, the most effective treatment options for SAD include light therapy, antidepressants, and cognitive behavior therapy, alone or in combination, as recommended by the American Family Physician 2. Some key points to consider when managing SAD include:

  • Light therapy with a 10,000 lux light box for 20-30 minutes each morning can be an effective treatment option
  • Antidepressants, such as bupropion, may be used as a long-term treatment or preventive intervention
  • Cognitive behavior therapy can also be an effective treatment option
  • Lifestyle interventions, such as increasing exercise and exposure to natural light, are also recommended It's essential to consult with a healthcare provider before starting any treatment regimen, especially if you're taking medications or have underlying health conditions. Additionally, while some supplements like omega-3 fatty acids, St. John's Wort, and SAMe may have some benefits for mood regulation, their effectiveness for SAD is not well established, and more research is needed to confirm their benefits 3, 4. Overall, a comprehensive approach that includes evidence-based treatments and lifestyle interventions is the most effective way to manage SAD.
