Which supplements actually help with sleep quality?

A friend once told me about a moment that crystallized his insomnia: lying in bed at 2 a.m., staring at the ceiling, heart racing from the caffeine he thought had worn off hours ago. He reached for a bottle of melatonin and poured a small mountain into his palm — a dose that would make a lab rat fall asleep.

The sleep supplement aisle is a graveyard of desperation, stocked with shiny bottles promising what the mattress ads don’t: real, lasting sleep. But here’s the catch — the ones that actually do something are the ones nobody pours a mountain of.

Melatonin is the most misunderstood. It’s not a sedative; it’s a hormone that signals darkness.

Then there’s ashwagandha, the adaptogen that’s more than just Instagram hype. Studies show it can reduce cortisol levels and improve sleep quality in stressed individuals.
