The only animal source found in Baby's Only Organic soy formula is the vitamin D, which is derived from wool lanolin. No animal loses its life. Our vitamin D has been clinically proven to be bio-available for infants.
The only non-animal source of Vitamin D available is a chemically derived extract that uses hexane chemical. So, in order to maintain organic status, we could not use that source. This non-animal source has not been clinically proven to be bio-available for infants, but it does introduce toxins. Therefore, we feel our source of vitamin D is a better form for infants.
