Overview
Pouring over cereal, into coffee or into a smoothie, this vanilla soy milk is a moderately sweet plant-based drink. Soybeans, added vitamins and natural flavor make up the recipe.
A vanilla option suits coffee and cereal without a separate sweetener, and the vitamin D2, B2, B12 and folate additions are listed. The limits are a conflicting protein figure and an allergen field that reads milk for a soy product.
Who it's for
Breakfast tables and coffee routines that avoid dairy and want some sweetness. People with soy allergies, or who need unsweetened milk, should choose another product.
Pros and cons
- Dairy-free and vegan
- Added vitamins listed
- Protein figure conflicts
- Allergen field reads milk
Performance notes
The vanilla flavor and moderate sweetness suit coffee and cereal, and the plant protein comes from soybeans. Added vitamins are listed in the ingredients. The listing gives conflicting protein figures and a short shelf life, so check the carton.
