Health claims aside, does it taste better? For $4 a quart, you might as well be drinking buffalo, sheep, or goat milk, which have the A2 beta casein variation.
I’ve read that it “helps” people with non-specific symptoms like bloating, but not those with lactose allergy or intolerance. That, and reviews in Nature refuting any benefit, suggest it’s a combination of marketing hype or woo.
I first heard of this last year, from a server at St. Vincent. He told a lactose intolerant guest she could eat a dish because the dairy was from a Guernsey instead of a Holstein cow. I told her she should not trust him partly because he wasn’t a doctor, but mostly because he described XO sauce as an “ancient Chinese sauce.”
