Lactofree sell milk, cheese, cream cheese, cream, yogurt and spread. They sell packs of 5 long life milk portions for use when out.
Philadelphia sell lactose free cream cheese.
Muller are now selling lactose free yogurts.
My local Tesco sell lactose free Brie, Mascarpone, Mozzarella and a range of gluten free and dairy free puddings.
They also sell things like diary free sour cream in a bottle, pesto and free from + dairy free meals.
St Helen's sell a number of goats milk products.
Personally I prefer skimmed goats milk to anything else, but I don't have milk in tea or eat cereal and don't eat yogurts so even my lactose free consumption is minimal! Fortunately (unfortunately for my waist) I adore cheese so get my lactose free fix this way!
