The present invention provides a glutathione derivative having a dramatically enhanced hematopoiesis promoting effect in the living body represented by the formula (I): where A represents H or a C1-C20 acyl group; R1 represents a C1-C26 alkyl group or a C3-C26 alkenyl group; and R2 represents H, a C1-C26 alkyl group or a C3-C26 alkyl group, with the proviso that compounds are excluded in which R1 is a C1-C10 alkyl group or a C3-C10 alkenyl group, and simultaneously R2 is H, a C1-C10 alkyl group or a C3-C10 alkenyl group. The present invention also provides a salt of the glutathione derivative, or a colloidal composition that enables the safe and effective development of the effects of the glutathione derivative in the living body.
