"Anyone have improvement in health by getting a better source of yogurt or dairy in their diet?"

If you go to the Weston A. Price Foundation website (www.westonaprice.org) and search, you'll find that they put their "letters to the editor" from their food journal, Wise Traditions, on that website. People have made testimonials there about the positive changes they associate with switching to raw dairy. They have a site search.
Full "letters" list:

Also, Organic Pastures (California) has a website with testimonials:

I know they had linked to a blog where there were comments about health benefits, but I couldn't find it just now. I think that was because they couldn't make health claims directly on the website.

Dunno if you've tried any web searches for something like "raw milk testimonials," but I came up with some stuff when I did that.

Personally, I have an instinctual feeling that continuing to slip in pasteurized dairy (when going to restaurants, for example) is not good for me. I had some pasteurized cream the other day, and it just tasted wrong. I don't know where that cream came from (though it was organic) and what all was done to the cows or to it...factory organic farms are a problem, though. For one thing, the cows may get fed something organic, but it's not necessarily good stuff for cows to eat (and not grass).

I can tell you this. For as long as I've had someone rub my back, I've had what I presume are calcified muscle tissue (I had these "knots" in my spinal erector muscles that just never changed with massage). In the last couple of years, during which I added raw dairy to my diet, those places feel more like normal muscle again. I've made lots of changes to my diet, so I'm not sure what were the causes of these changes to the muscles.

If you have access to good raw milk from a dairy you trust (www.realmilk.com):
There are cultures for making your own kefir (buy at the store, order from a cheese company, etc.)...or you could use the remains of some of your pasteurized stuff to get it going. You can always sour the milk with the cultures and not worry about your yogurt being thick (thickening requires extra steps - heating the milk).

Cow's milk could be a problem for you. I spoke to someone who had problems with almost everything dairy. I asked her if she tried goat cheese and she told me it didn't have the same effects.

We are the only species that drinks milk and milk products from other species.
