Rating (out of 5): 4

Sardines are not an herb or traditional supplement, but as a nutrient-dense food, they have scientific support for use during pregnancy. Sardines are rich in omega-3 fatty acids (EPA and DHA), high-quality protein, calcium, vitamin D, and vitamin B12, all of which are important in prenatal nutrition. Omega-3 fatty acids, especially DHA, are essential for fetal brain and eye development, and adequate maternal intake has been linked to better cognitive outcomes in children. Sardines are considered a safer seafood choice during pregnancy because they are low in mercury compared to larger fish.

Clinical studies and official guidelines (such as those from the American Pregnancy Association and the FDA) recommend low-mercury, omega-3-rich fish like sardines as part of a healthy pregnancy diet. While sardines are not a "supplement" per se, their nutrient profile can help support maternal health, reduce the risk of preterm birth, and contribute to the baby's neural development. Their high calcium and vitamin D content also support maternal bone health during pregnancy. However, it is important to consume sardines in moderation due to their sodium content (when canned) and to ensure they are prepared safely. In summary, the scientific evidence supports the inclusion of sardines in pregnancy nutrition, primarily due to their omega-3 and micronutrient content.
