The soy used in Baby’s Only Organic® Plant Based Soy formula is not fermented. Fermented soy products are made from soybeans that are often treated with brine and/or bacteria or fungi. Our Baby’s Only Organic® Plant Based Soy Formula is made from organic soy protein.
The issue with fermented versus unfermented soy is related to phytic acid. The following information may be of interest to you.
Phytic acid found in plant proteins is known to block the absorption of some minerals. This is especially true of zinc, iron and possibly copper & manganese. Therefore, the amount of some of these nutrients is adjusted (such as the addition of iron) when appropriate to ensure that the formula contains adequate amounts for bodily absorption.
