The Carb-Dense Game Changer
Finally, a sports chew that doesn’t mess around. The SiS Beta Fuel packs 45 g of carbohydrates into just two bars – that’s 30-50% more than any other chew on the market. No more fumbling with handfuls of tiny pie...

Great nutrition- wish the chew form was different
I've had great results using these on long trail runs. I prefer chews to gels because I often feel gels take more effort to get all the gel completely out of the pouch and can lead to stoppage/ fumbling with two hands. Chews are more straightforward to consume--however, these are a bit odd since they are two long strips of chew stacked on top each other in the package. Each strip has two indentations indicating 3 individual chews per strip. The problem is the two strips can at times be hard to pull apart, you have to gradually takes bites and hold onto a strip, etc. Compared to many other chews/blocks, these are not as easy to eat while on the move. I find Clif Bloks, Honey Stinger chews, etc., which are bite size and pre-portioned, to all be much easier to work with on the move. The orange and lemon flavors are good. I also would love to see a caffeinated flavor.
