Here unfiltered acv is usually available in places which sell organic products.Okay - I’m not sure they have this one here in Portugal but I will try to find an unfiltered one. He still doesn’t drink or eat, how much would you add in the syringe? Right now I feed him twice a day, each 15 ml… like one drop or 2 per feeding?
Are there supermarkets like Carrefour, Auchan or Géant Casino ? If yes, give a look at their organic section, if it's like here you should find unfiltered acv (the one which looks cloudy) there. In the common oil/vinegar section they have only the filtered ones (which look very transparent).
