I see, but he is not talking about potassium been essential for hydrochloric acid production.. That's what I am saying that potassium is crucial. Btw I took my first potassium in form of supplement(potassium chloride) with acid before and after meal and I feel great. No burping, indigestion nothing... I was so low on potassium for so many years + high physical stress + very high sodium and magnesium which crushed my potassium for sure..
You are focusing on solely digestion, which is okay - nothing you are saying is incorrect about digestion. But the effects of electrolyte therapy go beyond just improving digestion and, in the case of many PFS/PSSD guys here, is just as much about it's neurological impacts as it's digestion impacts. We have discussed both angles many times on this forum. We need chloride to regulate things like GABA.
Both potassium and chloride are essential for building stomach acid salts, especially the chloride if a person has high levels of other anions like phosphate and bicarb in their system, because they will push chloride out. If a person is very high in cations as well, supplementing potassium requires an anion to keep charges balanced. The body loses chloride easier than any other ion, so saying salt provides enough is inaccurate.
Honestly, most people here would be better off if they could get an IV + central line for electrolytes and HCl. Absorption would be much better and this would have more dramatic effects on neurological sides.
