Baby's Only organic dairy toddler formula with DHA and ARA 12.7g powder, 1,680 calories per can. The DHA used by Nature's One is a fatty acid from egg yolk, while other infant formulas use DHA derived from algae and fungus, which is a triglyceride. The use of egg phospholipids in infant nutrition has been widely studied and understood to be more easily absorbed and offer greater bioavailability than DHA from the form of triglycerides.
