Is there any lactose free options from SIS?

I am not aware of lactose in SIS gels.

How many calories do these have in them? I know this brand makes gels with either 100 or 180 calories each. How many are in this particular product?

Per 100ml 144 cal / Per 60ml 87 cal. I order for my wife whose Ironman/ITU Team USA Triathlete. She swears by them along with BOA Spray.
