DML - How is the Vitamin D in CeraLift sourced?

The Vitamin D is derived from lanolin taken from the wool of healthy live sheep living in Australian and New Zealand. The wool is sheared then crude lanolin is extracted from the wool using a scouring process, during which the fleece is washed in hot water.  (Note: This form of vitamin D3 is considered okay for vegetarians because the animals are not killed, but vegans may want an alternative source of vitamin D3 like one sourced from lichens).
