The verdict, by the numbers
5-HTP wins on approval — 84% vs 83% , essentially a tie. On conversation volume, Melatonin dominates: 47,515 upvotes of engagement versus 5,222. Note the split: the louder conversation is not the better-loved one — worth knowing before you follow the hype.
Fit beats ranking, though. Melatonin is the better match if your problem is timing problems — jet lag, shift work, a drifted schedule. 5-HTP fits mood-adjacent sleep issues (thin evidence). If you're unsure which problem you actually have, the 60-second Finder quiz sorts it.
