Comparison
Melatonin vs Lutein + Zeaxanthin
Melatonin
Pineal hormone regulating circadian rhythm. Low doses (0.3-1mg) often outperform higher doses for sleep.
Lutein + Zeaxanthin
Macular carotenoids that protect retinal tissue from oxidative damage. Multiple RCTs support reduced age-related macular degeneration progression.

The comparison in plain English
Auto-generated from dataMelatonin and Lutein + Zeaxanthin are both in the neuroprotective category respectively. Melatonin Pineal hormone regulating circadian rhythm. Lutein + Zeaxanthin Macular carotenoids that protect retinal tissue from oxidative damage.
Bottom line
Melatonin (evidence A, safety 5/5) matches the evidence base of Lutein + Zeaxanthin (evidence A, safety 5/5). Melatonin has the slightly cleaner safety profile. For users new to either, the higher-evidence option is the safer first try.
Choose Melatonin if
Melatonin is the better fit when your goal aligns with its mechanism (Endogenous hormone produced by the pineal gland in response to darkness, signalling the circadian sleep window) and the dose range (0.3–3mg) suits your protocol. Half-life is 1h.
Choose Lutein + Zeaxanthin if
Lutein + Zeaxanthin is the better fit when your goal aligns with its mechanism (Concentrated in the macula lutea (yellow spot) of the retina, where they absorb high-energy blue light and quench reactive oxygen species) and the dose range (10–20mg) suits your protocol. Half-life is —h.
