I assume that you mean healthy extra b? The 'a' choices are milk and cheese for the calcium and cereals/cereal bars are a 'b' choice.
But the answer is no I'm afraid. They do not have enough fibre to count as a healthy extra and need to be synned on all plans. You acn work out the syn values by dividing the calories by 20. As an aside Morrisons do some very similar bars in their Eat Smart range (apple and raspberry) that work out at only 4.5 syns. Not sure how these compare with the kellogg's ones but I suspect they are higher.
