- 01Vitamin D3Limited85% match
Reduced winter sunlight lowers vitamin D synthesis, and because D receptors are present in mood-related brain regions, low status may be associated with seasonal low mood, though a causal role is not established.
SuggestedVitamin D3 (cholecalciferol) with a fatty meal - 02St. John's WortModerate80% match
It appears to modulate serotonin, dopamine, and norepinephrine signaling and has shown benefit for mild to moderate depression in trials.
SuggestedStandardized extract (0.3 percent hypericin) - 03Fish OilLimited68% match
Omega-3 fatty acids, particularly EPA, are incorporated into neuronal membranes and may have modest anti-inflammatory and mood-supportive effects, though results are mixed.
SuggestedHigh-EPA fish oil - 045-HTPLimited63% match
It is a direct precursor to serotonin and may support serotonergic tone relevant to mood, but human trials for seasonal mood specifically are limited.
Suggested5-HTP (Griffonia simplicifolia extract) - 05Rhodiola RoseaLimited60% match
As an adaptogen it may influence stress-axis signaling and monoamine activity, potentially reducing fatigue and low mood, though evidence is preliminary.
SuggestedStandardized extract (3 percent rosavins, 1 percent salidroside) - 06MethylfolateLimited56% match
As the active folate form it supports one-carbon metabolism and monoamine neurotransmitter synthesis, which may matter more in those with low folate or MTHFR variants.
SuggestedL-methylfolate
