Magnezowymi

Magnezowymi is the instrumental plural form of the Polish adjective magnezowy. The root magnez indicates magnesium, a chemical element, and magnezowy is the adjective used to describe substances or properties related to magnesium. The instrumental plural form magnezowymi is applied when the modified noun is in the instrumental case and plural, for example in phrases like solami magnezowymi (with magnesium salts) or dodatkami magnezowymi (with magnesium additives). In broader usage, magnezowy can denote that a material or compound contains magnesium or is derived from it, though in scientific contexts the exact magnesium compound is usually specified, e.g., tlenek magnezowy (magnesium oxide) or siarczan magnezowy (magnesium sulfate).

The form magnezowymi does not carry a standalone meaning beyond functioning as a grammatical form; its role is to ensure agreement with the noun it describes in the instrumental plural. Spelling and declension follow standard Polish rules for adjectives ending in -owy. The term is common in chemistry, pharmacology, and nutrition when describing magnesium-containing products or ingredients.

Distinctions between magnezowy and magnetyczny (magnetic) reflect different roots: magnezowy for magnesium, magnetyczny for magnetism.
