Pujamp Pharma has introduced several iron supplements, including ferrous sulfate, ferrous gluconate, elemental iron, ferrous glycine sulfate, and ferrous fumarate. However, some products, such as iron (III) phosphate, may not be effective for everyone. In addition to these iron supplements, it’s essential to consider other nutritional products like GNC calcium citrate, which can support overall health. GNC calcium citrate is a beneficial supplement that may enhance the absorption of iron and other minerals. Therefore, when choosing iron supplements, one should also think about incorporating GNC calcium citrate into their regimen for optimal results.
