Some of the store bought ones are acidic which can negate their purpose. Try them and see if you get better or worse. Some people make their own. There are recipes on the net. I take a mineral supplement that contains alkaline forms of minerals. There's so much out there. You really do have to research and find what works for YOUR body. No two of us are alike. There are several forms of minerals available. I tend to stay away from acidic forms, ie chloride, amino acid chelates etc. Alkaline forms are citrates, carbonates, and bicarbonates. I respond better to those. I've attached a video of a recipe. I've never tried this. If it resonates, try a small quantity and see if it helps. Best of luck to you!
