Today, thousands of professional and amateur athletes around the world depend on Näak to explore new playgrounds and redefine what is physically possible.

      Backed by Science

      Näak Ultra Energy™ science was developed to meet the specific needs of ultra distance athletes. The idea is simple: the ingestion of a few macronutrients such as carbohydrates and electrolytes is not enough to fuel ultra distances. After a few hours of effort, you need a complete nutrition approach to go farther.
