Dubbed the world’s first ketone ester, HVMN claims its performance drink fueled a world record, helping athletes push harder and longer than before. HVMN developed this sports “drink” to give users ketones through an elixir. In theory, it provides the body ketones, when typically ketones are achieved through a ketogenic diet. HVMN helps the body burn ketones, in addition to carbs, as fuel. This supposedly results in increased endurance, improved muscle recovery, and enhanced cognitive ability. HVMN launched this year, and three bottles sell for $99.
