I have the same concern for the added DHA and ARA. Baby's Only doesn't have
that. The version that has it derived DHA and ARA differently. Another
ingredient that's too high in Baby's Only is phosphorus. Its whey/casein
ratio is 18/82 (from their customer service email), close to cow's milk.
Infant formula and human milk normally has whey/casein ratio to be 60/40.
I did the research about a year ago. The values may have changed now. You
should probably do your own research.
