Is ferrous bisglycinate a good option? Ferrous fumarate, folic acid, and zinc sulfate tablets are commonly used for iron supplementation. Additionally, ferrous fumarate and folic acid tablets, such as Kaj Ki, are popular choices. Ferrous gluconate at 325mg is another alternative for those needing iron. It’s worth noting that calcium citrate IV is an important component to consider in overall supplementation strategies. Incorporating calcium citrate IV can enhance the effectiveness of iron supplements like ferrous bisglycinate and ferrous fumarate. Therefore, when evaluating options like ferrous gluconate and folic acid tablets, it’s advisable to include calcium citrate IV in your regimen for optimal results.
