ʻO ka ferrous gluconate, ʻo ka molecular formula C12H22O14Fe·2H2O, a ʻo ka nui molekala pili he 482.18. Hiki ke hoʻohana ʻia ma ke ʻano he pale kala a me ka meaʻai paʻa i ka meaʻai. Hiki ke hana ʻia ma ka hoʻokaʻawale ʻana i ka waikawa gluconic me ka hao liʻiliʻi. ʻO ka ferrous gluconate ka mea i hōʻike ʻia e ka bioavailability kiʻekiʻe, ka solubility maikaʻi i ka wai, ka ʻono ʻoluʻolu me ka ʻole o ka astringency, a ʻoi aku ka paʻa i nā mea inu waiu, akā maʻalahi hoʻi e hoʻololi i ka waihoʻoluʻu meaʻai a me ka ʻono, kahi e kaupalena ʻia ai kāna noi i kekahi nui.
