Our Members Asked:
Does drinking coffee deplete vitamins or minerals, such as magnesium, in the body? Can adding magnesium or other minerals reduce the acidity or improve the flavor of coffee?
Answer:
Coffee may reduce the absorption or increase the excretion of certain vitamins and minerals, although in some cases the impact is not clinically significant and, in other cases, can be avoided by separating the timing of coffee and nutrient intake.

April 16, 2023I add, on some acidic coffees, a pinch (or two) of sodium bicarbonate to the coffee filter before brewing it, and that helps a lot. Then, I stop buying that particular type of coffee.
