even if it said no added sugar,there is still traces of it like sucrose and fructose which can make u and ur baby gain rapid weight. i used to drink frisomum which had no added sugar and at first i gain 2kg in 1month then the next month i gain 6kg. my dr told me that it contain sucrose and fructose.they dont recommend it. because of my rapid gain weight i had to do a glucose test twice and for both results its negative for diabetes and my baby size is just nice.if u decide to drink then drink it every other day or just takefresh milk.if ur lactose intolerant maybe try nutmilk like almond milk or soymilk.if not u can ask ur dr if u can take calcium supplements.
