The company is FIT & NU (short for “FITness” & “NUtrition”) – spelled in all upper case with an ampersand (&) standing for “and,” plus a space between each word. It is not spelled Fit & NU, FitNu, Fit N Nu, FIT&NU or FIT and NU. The word “and” is only spelled out and should only be combined with the other words if written as part of the domain or social media handles, such as @fitandnu and fitandnu.com.
