Most creamers are filled with either sugar or bad fats, or both. "Partially hydrogenated' oils are trans fats and you should avoid them if you possibly can. Natural Bliss has a very small advantage in that it's not a witch's brew of chemicals like most other creamers. The ingredients are nonfat milk, heavy cream, sugar, and a natural flavoring (probably vanilla or some vanilla substitute). Basically it's like full-fat milk with sugar and vanilla flavoring. If you didn't care about losing weight, you could use Natural Bliss, or (cheaper) milk, vanilla, and sugar.
There are lots of better choices, though. Maybe the easiest is to use powdered NF milk and then either a flavored sweetener or a SF syrup. For example, Splenda comes in three flavors - vanilla, hazelnut, and mocha. If you wanted to use a syrup, they come in dozens of different flavors, including vanilla. You can probably find them in the supermarket, in the same area with the coffee. Or, you could just add a drop of vanilla and whatever sweetener you wanted. (I think that would be the cheapest, too.)
You could also try evaporated NF milk, which comes in a can. It doesn't dilute the coffee as much. Of course, you could just use 1% or NF milk. You could get the vanilla flavor from either a flavored sweetener or a NF syrup.
Also, I don't know if you like flavored coffees (the kind where the flavor is in the beans or in the unbrewed ground coffee), but you can get that in vanilla flavor also. It's probably available in the supermarket or online. Before buying a lot, though, you might want to try a sample to make sure you like it.
