|Section2= |Section6= |Section7= }} Zinc gluconate (also called ''zincum gluconicum'') is the zinc salt of gluconic acid. It is an ionic compound consisting of two moles of gluconate for each mole of zinc. Zinc gluconate is a popular form for the delivery of zinc as a dietary supplement. Gluconic acid is found naturally, and is industrially manufactured by the fermentation of glucose, typically by ''Aspergillus niger'', but also by other fungi, e.g. ''Penicillium'', or by bacteria, e.g. ''Acetobacter'', ''Pseudomonas'' and ''Gluconobacter''. In its pure form, it is a white to off-white powder. It can also be manufactured by electrolytic oxidation, although this is a more expensive process. The advantages are a lower microbiological profile, and a more complete reaction, yielding a product with a longer shelf life. ==Zinc gluconate and the common cold== Zinc gluconate has been used in lozenges for treating the common cold. However, controlled trials with lozenges composed of zinc acetate have found the greatest effect on the duration of colds.〔( Hemilä H (2011) Zinc lozenges may shorten the duration of colds: a systematic review.

Med Hypotheses 74:482-92 )〕 Zinc has also been administered nasally for treating the common cold, but anosmia has been caused by such treatment (see below). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Zinc gluconate」の詳細全文を読む スポンサード リンク
