If you’re suffering from any supposed high acid problems, you are likely on a PPI or antacid medication of some kind, which can bring their own problems in that they can slow absorption and make you more vulnerable to nutrient deficiency, allergies and infections, so it can really pay dividends to consider the real underlying cause here.
Do have a read of my GERD/Acid Reflux factsheet where I have put loads of articles and resources for you to see what else it usually is. For example, it can be a zinc deficiency, a lack of certain B vitamins, stress, a lack of stomach acid so the production of acid doesn’t switch off, bacterial infection, food allergy and others. Lots to investigate there than just taking a pill.
I am asked about this a great deal so hope this factsheet helps for you. Do have a read.
