I'm wondering about this after reading Dr. Tulio Simoncini's book(well I skipped a lot)and feeling quite impressed with his treatment successes. Some people are ingesting baking soda and feeling it has helped. I would like to know if anyone knows more about sodium bicarbonate. For example I read that its best to buy a pure form from the pharmacy, as Arm & Hammer may have aluminum in it. I went to CVS(large pharmacy chain)and all they had was sodium bicarbonate capsules in a bottle for 15$, and it wasn't much of an amount by weight. Dr. Marc Sircus recommended putting like ten pounds in the bathtub. I am just beginning to learn about his work, using magnesium, and also about sodium bicarbonate. They both seem like great things because they are simple and natural, if they offer the type of benefits that are claimed. What does anyone know about these, what are your experiences(by the way I just took a bath with some Acient Mineral flakes, just purchased, so I have begun)and especially how can I buy and use sodium bicarbonate? I have a numnber of health issues, including adrenal fatigue/thyroid, weak muscle mass, depression/compulsive eating, and possibly cancer. Any info is appreciated.
