GB 1903.29-2018 is the Chinese national food safety standard for the food nutrition fortifier magnesium gluconate. It applies to the substance obtained by chemical synthesis and purification from gluconic acid, or glucono-delta-lactone, together with magnesium oxide or magnesium carbonate.

The standard fixes the chemical name D-magnesium gluconate, the molecular formula C12H22MgO14-nH2O with n equal to 0 or 2, the structural formula, and the relative molecular masses 414.60 for the anhydrous form and 450.63 for the dihydrate, both from the 2016 international relative atomic masses.

It then gives the technical requirements, starting with the sensory requirements of Table 1: a white to off-white powder or granule, odourless, examined for colour, state and smell in a white porcelain dish under natural light. It was issued on 21 June 2018 and has applied since 21 December 2018.
