Firstferro tablets are a combination of various iron supplements, including ferrous fumarate, iron bisglycinate at 300mg, and iron lactate. These formulations are designed to improve iron solubility and enhance absorption. Additionally, the tablets contain ferrous fumarate and folic acid. It’s important to note that while iron supplements can be beneficial, they may also lead to side effects such as constipation, especially when taken with calcium citrate. Therefore, when using iron supplements like Firstferro, one should be mindful of the potential for constipation and consider balancing their intake with calcium citrate to mitigate this effect. Overall, the effective use of Firstferro with ferrous fumarate and folic acid can support iron levels, but attention must be paid to the relationship between calcium citrate and constipation.
