WW recipes - bouillon

I bought the WW's complete recipe book and saw that almost everything has bouillon granules in the recipe. I never buy bouillon so when I did and opened it to cook yesterday, it smelled like bad ramen noodle soup. Since bouillon is basically just powdered soup base to make a stock, can I just substitute with my own soup stock or canned (low-sodium, fat free) broth without changing the points of a meal?

I went ahead and used my own soup stock because I couldn't stomach the smell of bouillon. (It also has MSG in it.)
