Almond milk is safe to drink during pregnancy. It’s much better for you if it’s both unsweetened and without added thickeners or artificial flavorings. Many women choose a vegan alternative (like almond milk) to real milk because of either a dairy allergy or intolerance. Almond milk doesn’t have the same nutrition as regular milk (it doesn’t have nearly the same amount of protein for example), but it is fortified with things like calcium, vitamin D and magnesium and is totally safe to consume during pregnancy.
