Study design. Six-week-old female C57BL/6J mice were randomly assigned to the VDsuf or VDdef diet and fed the assigned diet for 5 weeks before mating with a control diet-fed male. 1.5% calcium gluconate water was supplemented to VDdef diet-fed group. After delivery, all F0 mice were fed VDsuf diets. The offspring were fed VDsuf diet after weaning and maintained the diet until the sampling.
