Anyone know of a lower sodium alternative to soy sauce?

Even light soy sauce has tons of sodium in it. I have turned every brand of soy sauce bottle around that I've ever come across in any store...and they always have at least 550mg per tablespoon.

I *thought* I found a good one today when I was at Fresh Market and came across Bragg's Liquid Amino. It said it was a natural alternative to soy sauce, that it was naturally lower in sodium, and it said 160mg of sodium per serving.

And I made a rookie mistake. I didn't check the serving size before I bought it. I didn't even think to check it until after I'd used it in my gravy recipe tonight and had gone to the computer to track it to see (I was so excited!) how much lower in sodium my gravy would end up being!

Turns out, the serving size wasn't 1 T like soy sauce is. It wasn't even 1 tsp. It was HALF a teaspoon. Which meant that a full tablespoon would have 960mg of sodium. Which is basically like regular soy sauce!!!! I'd have done so much better to stick with my lite soy sauce.

I was so disappointed, and I was so annoyed with myself for making the mistake of not checking the serving size. I always remember to do that when I'm looking at foods in the store!

So now I have this nearly-full bottle of what is basically soy sauce that I never want to use. What on earth am I going to do with it?

And is there ANY soy sauce out there that is actually low in sodium?
