GU Energy
Whether a marathon, an ultra, a tri, or an endurance event, determination, consistent training, and proper nutrition are essential. With this in mind, Dr. Vaughan created a gel for his daughter, an ultra-runner. At the start, it was not easy to digest, but as the years progressed, the recipe was perfected, and today, it is one of the go-to nutrition supplements for endurance athletes. The gel provides the required carbs for energy and amino acids for muscle support. Since then, GU has diversified into chews, drinks, waffles, capsules, and gear. Their website is a helpful trail for their products.
