Most supplements in the nerve-support category use proprietary blends. NerveHarmony doesn't — and that distinction is worth understanding.
A proprietary blend names its ingredients but not their individual amounts, making it impossible to know if you're getting a meaningful dose of any single component.
NerveHarmony prints the exact milligram amount of each of its five ingredients. That lets you directly compare the formula against published research on passionflower, marshmallow root, and the rest.
Dosage transparency doesn't guarantee a formula works, but it does let you make an informed decision rather than trusting a black box.
