Melatonin

Melatonin as it relates to Seasonal Affective Disorder in Health report: Your Genetic Risk for Seasonal Affective Disorder

Melatonin is a hormone that is naturally produced by the pineal gland in the brain. It plays a crucial role in regulating the sleep-wake cycle and is often referred to as the "hormone of darkness" because its production is triggered by darkness and suppressed by light. In the context of Seasonal Affective Disorder (SAD), melatonin levels can be disrupted due to the changes in light exposure that occur during the winter months. People with SAD may experience an overproduction of melatonin, leading to symptoms such as excessive sleepiness, fatigue, and difficulty waking up in the morning. One common treatment for SAD involves light therapy, which helps to regulate melatonin production by exposing individuals to bright light in the morning. This can help to suppress the overproduction of melatonin and alleviate symptoms of SAD. In addition to light therapy, some individuals with SAD may also benefit from melatonin supplements. These supplements can help to regulate the sleep-wake cycle and improve overall sleep quality, which can be particularly beneficial for those experiencing disruptions in their sleep patterns due to SAD. Overall, melatonin plays a crucial role in the regulation of the sleep-wake cycle and can be a key factor in the management of Seasonal Affective Disorder. By understanding how melatonin levels are affected by light exposure, individuals with SAD can work with their healthcare providers to develop a treatment plan that addresses their specific needs.

Supplements for Seasonal Affective Disorder

Here are some dietary supplements related to the content in this report. Click the shopping cart to purchase the supplement from our partners.

  1. St. John's Wort

    This herbal supplement is thought to inhibit reuptake of serotonin, norepinephrine and dopamine, helping boost mood. Some clinical studies have found it effective for SAD treatment.

  2. Saffron

    Saffron is believed to increase serotonin availability. Small studies show saffron supplementation can improve mood in SAD patients.

  3. Ginseng

    Ginseng contains active compounds called ginsenosides that may modulate neurotransmitter levels. Data suggests it may help regulate circadian rhythms.

  4. Vitamin D

    Low vitamin D levels have been associated with SAD. Supplementing during winter may compensate for the lack of sunlight exposure.

  5. Probiotics

    Alteration of gut microbiota may influence neurotransmitter synthesis and circadian clock genes. Probiotic supplements may help realign biological rhythms.

  6. Omega-3s

    DHA and EPA omega-3 fatty acids support serotonin and dopamine activity in the brain. Omega-3 supplementation may improve SAD symptoms.

  7. Magnesium

    Involved in melatonin production and circadian regulation. Magnesium supplementation has shown some benefits for seasonal depression.

  8. 5-HTP

    5-HTP is a precursor to serotonin synthesis in the brain. It may help boost serotonin levels reduced in SAD patients.

  9. Rhodiola rosea

    An adaptogen thought to regulate neurotransmitter levels and cortisol production. May alleviate SAD mood symptoms.

  10. Lavender

    This aromatic herb contains compounds like linalool that modulate serotonin and possibly melatonin levels in the brain. Small studies show lavender can improve mood in SAD.

  11. Chamomile

    Has apigenin, which acts on GABA receptors and flavonoids that may boost serotonin. Limited evidence it may help alleviate SAD symptoms.

  12. Vitamin B12

    Important for neurotransmitter synthesis and circadian gene expression. Supplements may correct B12 deficiencies linked to seasonal depression.

  13. Creatine

    Plays a role in energy metabolism in the brain. May be beneficial for mood and cognitive issues in SAD patients.

  14. Melatonin

    Directly regulates circadian rhythms and sleep-wake cycles that are disrupted in SAD. Timed melatonin supplements may improve this dysfunction.

  15. Valerian

    Contains valerenic acid that modulates serotonin receptors and GABA activity to promote relaxation and sleep regulation. Some benefit seen for SAD.

  16. Brahmi

    Ayurvedic herb that may regulate dopamine, serotonin and acetylcholine levels. Limited support for use in seasonal depression therapy.

  17. L-tryptophan

    Amino acid precursor to serotonin. Shows some efficacy in small studies for SAD treatment.

It is essential to consult your healthcare provider before starting any of these supplements. They can have side effects, and some may interact with medications or other supplements you're already taking.
