Hi Littlemama,
I am apologetic of what I will say beforehand because I may offend you for saying the following:
If you do not react to raw milk but to pasteurized milk, it is not because you are lactose intolerant but you probably have something else.
Raw milk (i.e unpasteurized milk) does not contain enzymes but rather milk loving bacteria which will eat the lactose and covert it to lactic acid (sour taste). If you consume your raw milk a little on the sour side then it's possible the lactose is all gone. Any cultured product be it from raw or pasteurized milk are made by adding bacterial cultures that eat the lactose.
Raw milk and pasteurized milk have the same amount of lactose (more or less depending on fat content). Even human breast milk is very high in lactose which is an essential nutrient for an infant's brain development.
Grant you, I believe raw milk is more easily digestible and that pasteurized milk proteins are remarkably altered because of the pasteurizing process.
Our human evolution, like all other mammals, has made us capable of digesting lactose only in the first years of life then we are meant to lose that ability because it becomes useless. On earth there are more people that are lactose intolerant (normal) then people capable of eating milk.
As Kuan mentionned... <cultured> dairy is key to reducing lactose not organic. From a reputable company, organic or not, even better.
Don't get me wrong, I also think raw milk (if handled properly) is superior then pasteurized milk. Raw milk from pastured cows (if handled properly) is by far superior!
(my post are always too long but if somebody asks about details for lactose, composition, brain development etc.. I will gladly answer)
