Firsiron II acetate, along with ferrous fumarate at a dosage of 200 mg, is commonly used to address iron deficiency. However, ferrous gluconate can lead to constipation for some individuals due to its elemental iron content. On the other hand, iron bisglycinate is known for its better absorption and reduced gastrointestinal side effects. For those seeking an alternative, calcium citrate oral tablets (950 mg) can also be considered, as they provide a good source of calcium without the constipation associated with some iron supplements. It’s important to note that when using calcium citrate oral tablets (950 mg), one should monitor iron levels and adjust supplementation accordingly. Remember that calcium citrate oral tablets (950 mg) can be beneficial in maintaining overall mineral balance while managing iron intake effectively.
