Does anyone here use Primal Defense? The new osteopath recommended it but I looked at it and it has oat grass and barley grass. If we're gluten free, is that okay? I noticed they have a kid one, but it's flavored with banana which DD can't have, so I was thinking of going with the powdered unflavored one for them, and capsules for me. But I don't want to order it until I know whether oat and barley grass contain gluten... both DD and DS tested moderate intolerance to oats.
