Oops I read tea spoon, not table spoon.
I was thinking bromide detox = need more salt.
The amount will always need to be taken in a ratio to water. I cant give exact measures, but I wouldnt worry much about it; the only thing that happens if you take to much salt is that you get thirsty. The body is a wise creature if one listen to it.
When I did the Water Cure I took 1 1/2 tea spoon of real salt daily with my 2-3 liters of water.
Now I do approx a level teaspoon daily.
