When we purchased it (it was still legal several years ago), the instructions were in English. We followed the mixing guide, we knew what the ingredients were (because we researched) including the milk proteins.
The formulas available on the American market were all loaded with sweetener and caused colic. This is an anecdote, but so is what's presented in that article.
Interesting. Sucrose, glucose, fructose have same amount of calories as lactose, just different sweetness (apparently evolutionary trait so that babies don’t get too addicted to milk).
