Reduce rash

What this outcome means

A rash is a visible flare of irritated skin — redness, bumps, or eruptions that can itch, sting, or simply look inflamed. On DoseRank it maps to a defined health outcome built from human studies on affected skin area, lesion severity scores, and itch ratings – data sourced from open sources and specialized resources. DoseRank is not medical advice.

Who it's for

Flare-prone skinRecurring eczema or dermatitis that comes and goes in patches.

Contact reactionsSkin that erupts after touching irritants, metals, or fragrances.

Itch-and-scratch cycleInflamed patches where itching keeps the eruption going.

Stack buildersAlready taking supplements such as Shiitake and want the dose right.
