  • What is the difference between slow burning and fast burning energy?

    Our Slow Burning products are made with raw seed and nut butters. The healthy fats and protein in these nut butters metabolize slowly. When combined with our mineral rich and low glycemic electrolyte base, the result is a clean, sustained fuel source for your longer adventures.

  • Muir Energy is thicker than other gels. Why is that?

    Bacteria and pathogens proliferate in an aqueous environment. To keep their products food safe, thinner or watery gels must use synthetic preservatives. We use exclusively real food ingredients with no synthetic preservatives. We have accomplished this by reducing the water activity in our products. This results in a thicker, more viscous - as well as more flavorful, nutritionally and calorically dense - product.
