"Phoenix Worms are also a natural weapon against coccidia.
In addition to having a perfect balance of calcium and phosphorus,
Phoenix Worms provide high levels of natural lauric acid. Lauric acid
is known for its excellent antimicrobial properties including potent activity
against lipid coated viruses, clostridium and pathogenic protozoa including
coccidia. Lauric acid is a medium chain saturated fatty acid found in Phoenix
Worms as well as some vegetable oils and in dairy products. 53% of the fat
in Phoenix Worms is beneficial lauric acid, a proven antimicrobial especially
effective against coccidiosis."
