A method for rapidly chelating calcium by amino acid is disclosed. The method at least comprises the following steps: providing an amino acid and a calcium source； and performing a chelation reaction of the amino acid with the calcium source by using a homogenizer to manufacture a calcium-amino acid chelate. The chelation ratio of the amino acid and the calcium source can be improved and the chelation time can also be decreased.一種胺基酸快速螯合鈣之方法，至少包含下列步驟：提供一胺基酸及一鈣源；以及以均質機令胺基酸及鈣源進行一螯合反應，藉以製備胺基酸螯合鈣。此胺基酸快速螯合鈣之方法可提升胺基酸與鈣源之螯合率，並縮短螯合時間。
