Emma, you are right to be concerned about the concentration and balance of electrolytes in your system. But with a juice fast there is probably nothing to worry about, as most vegetables and fruits contain enough natural Sodium (Na) and Potassium (K) to provide a healthy balance.

Typically, where electrolyte problems arise during a fast is with taking in too much plain water, either drinking it or when using enemas and/or colonics.

If you are taking regular enemas while fasting, you should add 1 teaspoon of Sea Salt or non-iodized table salt for each pint of water, or 4 teaspoons for a full bag enema. Never drink distilled water. If you are using bottled water, use spring water. Your body needs the minerals naturally present in most spring waters.

Hope this helps, Valerie
