Gadusol is a secondary metabolite and natural sunscreen produced by various organisms, including marine vertebrates and invertebrates, amphibians, reptiles, and birds.^[1]^[2]

It functions by absorbing ultraviolet radiation through its conjugated ring structure, blocking it from damaging biomolecules.^[3] Gladusol is closely related to the mycosporine-like amino acid family,^[2] a group of metabolites primarily produced by organisms in high-sunlight environments that absorb UV radiation. Structurally, gadusol is a substituted cyclohexenone.
