'nutrient-replenishing' originates from modern English, formed as a compound of 'nutrient' and the present participle 'replenishing' (from 'replenish').

'replenish' comes via Old French (repleniss-) from Latin 'plenus' meaning 'full'; 'nutrient' derives from Latin 'nutrire' meaning 'to nourish', with the English noun 'nutrient' emerging in the 19th century. These elements combined in modern English to form the compound 'nutrient-replenishing'.

Initially the components meant 'providing nourishment' ('nutrient') and 'making full or restoring' ('replenish'); combined, the compound's meaning narrowed to specifically indicate 'restoring or supplying nutrients'.
