Itâs so complicated. But based on my research, it has more to do with iron and copper. The magnesium, potassium, sodium, and whole food vitamin c are supposed to help regulate the malabsorption of iron into the liver through copper. So itâs not âtoo muchâ or âtoo littleâ iron, itâs how too much iron is being absorbed into the liver and trapped. Basically, copper helps regulate the iron and the trace minerals help regulate the copper đ¤Śââď¸
