Power Bar gels have more sodium than many other brands. Extra sodium can reduce muscle cramps.
I am currently testing out some gels in search of a more runnier gel for cold weather use. The Strawberry Banana PowerBar Energy Gel definitely met my cold weather gel needs; it is more runnier than GU gels. It tastes like children's medicine, but it's livable. Will love the extra sodium when needed; I am hoping it will bust some cramps.
