I bought this oat drink at Migros last Friday. At first I asked at Migros what the calcium was all about, whether it was artificially added? I was told that the calcium was of natural origin. I then bought two packs of this drink.
I assumed that oats contained so much calcium?

Only when I got home did I see that, according to the small print, this drink contains the
red algae Lithothamnium calcareum
has been added. The algae is therefore responsible for the high calcium content.

Why isn't the oat drink available without algae? I would prefer that. I know it's an Alnatura product, but you can buy it in Migros. So here's my wish in the hope that it will be heard.
