I am recommending doses for baths ranging anywhere from 2 to 4 pounds to even 6 pounds of magnesium flakes or a combination of flakes with Dead Sea salt and perhaps even Epsom salt. I am not talking about a nice hot magnesium bath for simple relaxation but a professional bath intended for a strong therapeutic effect. Sodium bicarbonate can be added starting from one cup to upward of a few pounds. See my essay on bath bombs, which is all about adding citric acid to the mix, which turns the sodium bicarbonate into carbon dioxide microbubbles. These baths can be taken 3 times per week.
