Hi, Waupaca here.... Have you had an Organic Acid Test? It may rule in or out some questions about ph. I have been following a low oxalate diet with amazing improvements. If by chance you have high oxalates, taking certain types of magnesium will exacerbate oxalates. Magnesium is important to take. I take magnesium citrate and only after meals. There is a calcium ratio that is important with magnesium. I take calcium citrate before I eat. D3 is important for the balance as well and exercise to get everything moving where it needs to go. I have swapped out high oxalate foods slowly with medium and then low oxalate ones for less side effects. Might be worth a look, it was for me.
Wanted to mention that too much antibiotics will damage oxalobacter formigenes, good bacteria in gut that degrades oxalates, so a good probiotic is important to replenish.
