I don't know, I can only remember that Andreas said a couple of years ago, to make sure there were not any other ingredients.

Yes it's fine. I asked the same thing at my organic health food market. I checked all the different brands and ended up buying:

SOURCE NATURALS Magnesium Malate" yielding 833 MG Malic Acid - 1250 MG (writing this info from front of bottle)

On the back of bottle, the supplement facts are:

Sodium 5mg
Magnesium (as magnesium malate) 425 mg
Malic Acid (as magnesium malate and malic acid) 2.5g

So!... when I asked the counter person about ONLY getting Malic Acid, she told me that this is it. It worked. Now I haven't tried Wild Oats but I'm assuming that they have the same brand and others with the same type of ingredients.
