Taking iron supplements, D3 supplements, and fish oil is believed to support fertility for various reasons. Fish oil supplements, particularly those containing omega-3 fatty acids, may improve fertility by supporting healthy fetal development and improving egg quality. It has been suggested that the omega-3 fatty acids found in fish oil support fetal brain and eye development, potentially improving overall egg quality as well as male fertility.

Vitamin D3 supplements are also important, as vitamin D deficiency has been linked to reduced fertility and adverse pregnancy outcomes. Therefore, ensuring adequate vitamin D levels may support fertility and overall reproductive health.

Furthermore, iron is crucial for proper reproductive function, and iron supplements can help to address any deficiencies that may impact fertility.

It's important to note that while research supports these potential benefits, individual responses to supplements can vary, and it's always best to consult with a healthcare professional before beginning any supplementation regimen.
