Ramelteon for SAD? Don't bother.

The evidence for using melatonin agonists like ramelteon in seasonal affective disorder is weak at best, and no major treatment guidelines recommend them.

Here’s the deal: SAD is linked to circadian rhythm disruption and shorter daylight, so melatonin sounds like it makes sense. But the actual studies are tiny and conflicting. Ramelteon was designed for insomnia — it works on the same receptors as melatonin but with longer action. A handful of small trials looked at it for mood in SAD, and the results were essentially “maybe a little something, maybe nothing.” Nothing you’d bet on.

Light therapy is still the gold standard. It’s cheap, well-studied, and works for most people.
