Suicidal thoughts, self-harm thoughts, feeling unsafe, mania, psychosis, severe depression, major behavior changes, or inability to function require urgent or emergency mental-health support.

When To Seek Medical Care
- Seek urgent or emergency support for suicidal thoughts, self-harm thoughts, feeling unsafe, psychosis, mania, severe depression, major behavior changes, or inability to function.
- Get medical review for new or worsening depression, medication changes, postpartum mood symptoms, substance use, bipolar symptoms, or unexplained fatigue.
- Review mood-active supplements such as saffron, St. John's wort products, SAMe products, ashwagandha, omega-3, and vitamin/mineral megadoses with a qualified professional.

Medication & Safety Cautions
Omega-3 Fish Oil
Omega-3 supplements are studied for depression, but NCCIH says it is uncertain whether they help depression symptoms. | blood thinners | bleeding risk | surgery
Saffron
Saffron has meta-analysis evidence in depressive-symptom contexts, but mood symptoms and antidepressant use require medical care and product/dose review. | pregnancy/breastfeeding | mood medications
Folate
Folate supports methylation and red blood cell formation; deficiency context can overlap with mood and fatigue evaluations. | The UL applies to folic acid from supplements and fortified foods, not naturally occurring food folate.
Vitamin D
Vitamin D status is often discussed in mood contexts, but supplementation should follow ordinary DRI/UL, testing, and safety context rather than broad depression claims. | Avoid chronic high-dose use above the UL without medical supervision.
Iron
Iron deficiency can cause fatigue, low energy, and concentration issues that may overlap with low-mood complaints, but iron requires testing and cause-based evaluation. | Iron overdose can be dangerous, especially for children. High-dose use should be guided by a clinician.
Ashwagandha
Ashwagandha may affect stress measures, but depression, antidepressant use, thyroid disease, pregnancy, liver concerns, and sedative use need clinician review. | pregnancy/breastfeeding | thyroid disease | autoimmune disease
