I question why you're touting this product as low sodium when, according to the package, a prepared cup of the soup is 880 mg of sodium - more than half of my daily allowance of 1500mg! Yes, the mix is low sodium, but no one is going to eat the mix dry. Buyer beware!!
The sodium of the prepared product will greatly depend on what you use to finish the recipe, using unsalted chicken broth (Swanson’s unsalted chicken broth for example which is 40mg sodium for a 1 cup serving vs others which can be near 900mg for a 1 cup serving)
