This popular supplement may increase risk of birth defects, study finds
Why it matters: Your daily antioxidant could impact future generations, urging caution for men planning families.
- Texas A&M University research indicates that high doses of antioxidants like NAC and selenium can lead to developmental differences in offspring, specifically affecting skull and facial structure.
- Male mice given these supplements for six weeks produced offspring with noticeable craniofacial changes, despite the fathers themselves appearing healthy.
- Dr. Michael Golding's team initially explored antioxidants to counteract oxidative stress from alcohol but unexpectedly discovered the supplements alone caused issues, suggesting an imbalance from excessive intake.
- Sperm DNA alteration is believed to be the mechanism behind these birth defects, highlighting a potential hidden cost of popular supplements.
A new Texas A&M University study reveals that high doses of common antioxidant supplements like NAC, often perceived as beneficial, may surprisingly increase the risk of subtle facial and skull birth defects in offspring, even when fathers show no outward health issues. This unexpected finding, published in Frontiers in Cell and Developmental Biology, suggests that excessive antioxidant intake can alter sperm DNA, raising concerns for men planning to conceive.
