Our Selection Criteria

What We Look For

Melatonin-free or very low-dose (0.5mg max) — high-dose melatonin is not the answer

High-dose melatonin can cause daytime grogginess and tolerance buildup. We prioritize evidence-backed alternatives that support natural sleep cycles.

Evidence-backed ingredients: magnesium glycinate/threonate, L-theanine, apigenin, glycine

These ingredients have peer-reviewed research supporting their role in sleep quality, relaxation, and GABA production without side effects.

Non-habit forming — no tolerance buildup over time

We recommend products you can use long-term without developing dependency or needing to increase doses for the same effect.

Third-party tested for purity and label accuracy

Independent testing ensures the product contains what's on the label and is free from contaminants, heavy metals, and undisclosed ingredients.

Not just melatonin in a fancy bottle.
