KEY CHARACTERISTICS & PRODUCTION of CALCIUM SALTS OF FATTY ACIDS:
*Manufacturing:
Produced via saponification, where free fatty acids (often derived from palm, soybean, or cottonseed oils) are reacted with calcium oxide or calcium hydroxide.

*Rumen-Inert Properties:
Because Calcium Salts of Fatty Acids form insoluble ionic bonds, they remain largely inert in the neutral pH environment of the rumen.
This prevents Calcium Salts of Fatty Acids from negatively impacting fiber digestion.

*Intestinal Absorption:
When Calcium Salts of Fatty Acids reach the acidic environment of the abomasum (the true stomach, with a pH of ~2.5), the bonds break down, allowing the animal to digest and absorb the fatty acids in the lower gut
