Someone noticed that Silk Soymilk listed Vitamin A Palmitate as one of its ingredients and contacted The Vegetarian Resource Group wanting to know if this ingredient could be animal-derived. According to VRG’s ingredient guide, palmitic acid which is used to produce vitamin A palmitate can be derived from soy oil although it also can be animal-derived. See: https://www.vrg.org/ingredients/index.php#palmitic_acid.
Silk has this statement on their website:
“Our almondmilk, soymilk, coconutmilk, cashewmilk, blends, creamer products and yogurt alternatives are completely vegan! There are no animal products, by-products or derivatives in these products, and the calcium we use in these products is derived from natural limestone. All other vitamins and live cultures used to fortify these products are vegetable-based.” See: https://silk.com/faqs
According to Silk, their products are vegan and the vitamin A is not animal-derived.
