Don't worry, I bought GeniusFirst DHA in Sendu YEATION. It was imported from New Zealand and has a purchase record. I have used it for my baby for half a year, and I can feel his concentration. Before attending early education, the teacher said that he was always distracted. Mothers should all know the efficacy of DHA, just want to choose a safe brand for their baby. I am very satisfied with GeniusFirst DHA from Xiandu.
