Antioxidants and Pregnancy Complications Exploring Therapeutic Strategies for Better Outcomes

Introduction:

Main Content Sections:

Oxidative stress, an imbalance between free radicals and antioxidants, is associated with pregnancy-related disorders. Conditions like preeclampsia and GDM are marked by increased oxidative stress, leading to endothelial dysfunction and systemic inflammation, further complicating pregnancy outcomes.

How Antioxidants Counteract Oxidative Stress

Antioxidants such as vitamins C and E, selenium, and phytochemicals neutralize free radicals. By doing so, they protect maternal and fetal tissues from damage, ensuring optimal fetal development and reducing the risk of complications like preterm birth and intrauterine growth restriction (IUGR).

Clinical Evidence of Antioxidant Efficacy in Pregnancy

While some studies show the benefits of antioxidant supplementation in reducing preeclampsia risk, others report mixed results. The variability in findings highlights the need for well-designed, large-scale randomized controlled trials to determine the safety and optimal dosage of antioxidants during pregnancy.

Mechanisms of Action: How Antioxidants Work

Antioxidants neutralize reactive oxygen species (ROS), preventing cellular damage and supporting placental function. They also help regulate redox signaling pathways, reduce inflammation, and protect against DNA damage, ultimately promoting healthier pregnancy outcomes.

Challenges and Considerations in Antioxidant Supplementation

Determining the appropriate dosages and timing for antioxidant supplementation remains challenging. High doses may pose risks, and the interactions between antioxidants and other nutrients or medications need to be carefully managed.
