I purchased this for fertility treatments, but I am now selling it because I am pregnant. I bought it in July, and it is new and unopened. I conceived healthy twins through IVF. Please feel free to use it as a good luck charm for your fertility journey ^^ [Reprinted from the product description] This product combines Japan's only "pregnant woman" derived Lactobacillus bacteria from the vagina/uterus with high-purity lactoferrin 150 mg.
