FAQ
Is this formula vegan?
No. While the base is soy, most infant formulas, including this one, contain DHA and ARA derived from fish oil or other animal sources, making them not strictly vegan.
Can I use it in cooking or baking?
It's designed for infant nutrition, not as a general-purpose ingredient. Using it in recipes would alter the nutritional profile and isn't its intended use.
How does it differ from regular soy milk?
Infant formula is a precisely engineered, complete food with specific vitamins, minerals, and fats (like DHA) essential for baby development. Regular soy milk is a beverage and lacks these critical nutrients for infants.
