Ferrous sulfate 325 mg may have side effects, particularly when taken as time-release capsules of ferrous fumarate. For example, Ferro 3 tablets, which contain ferrous fumarate 162 mg, can also present similar concerns. It is important to note whether you can take folic acid tablets alongside iron tablets, as this combination may affect absorption or digestion. Additionally, incorporating ccm calcium into your regimen could be beneficial, but you should consider potential interactions. Always consult a healthcare professional to ensure that taking ferrous fumarate, folic acid, and ccm calcium together is safe and effective for your health needs.
