A2 milk is pure, natural milk without added growth hormones, antibiotics, or other additives. It's safe for cows and safe for you! Even though it might cost a little more than regular milk at the grocery store, it's worth it. A2 milk is the only type of animal milk that has been scientifically shown to be both compatible with humans and easily digested by them. When cows are switched to A2 type milking in the last eight weeks of their pregnancy or before they give birth - this significantly increases life expectancy, reduces medical costs, and substantially improves fertility rates in cows.
