Worldwide, antenatal depression affects 15 to 21 percent of expectant mothers, with potential repercussions on birth processes, child development, and an increased likelihood of postnatal depression. While traditional treatments like therapy can be hard to access, and antidepressants pose certain risks during pregnancy, an alternative solution has emerged.
Research over the last two decades suggests a link between poor nutrition and mental health challenges. Troublingly, according to a New Zealand cohort study, only 3 percent of pregnant women meet the full nutritional guidelines.
Moreover, a cohort study from Brazil revealed that ultra-processed foods make up over 30 percent of daily energy intake during pregnancy, often replacing more nutritious food options. Such nutrient-deficient diets have been associated with increased risks of mental health issues in children, including depression, anxiety, and problems with hyperactivity and attention.
It’s argued that boosting nutrient intake and reducing consumption of ultra-processed foods during pregnancy may benefit both maternal and future child mental health, serving as a potential solution to antenatal depression. However, dietary changes alone may not be enough; additional nutrient supplementation could be key during this critical health period.
The Role of Micronutrient Supplementation in Treating Depression
Going beyond general observations, dedicated research, such as the NUTRIMUM trial, has investigated the effects of micronutrient supplements specifically designed to treat antenatal depression. The trial, which spanned from 2017 to 2022, included 88 pregnant women in their second trimester with moderate depressive symptoms, who took either a broad-spectrum micronutrient supplement or an active placebo, revealing significant improvements in overall psychological functioning among those on micronutrients.
Despite similar decreases in depression symptoms across both supplement and placebo groups, those on micronutrients reported better sleep and day-to-day functioning, with no safety concerns or side effects observed. The implications extend to those with a history of mental health issues or prior psychiatric medication use, highlighting the broad potential of this approach.
The Lasting Benefits Beyond Maternal Health
Long-term monitoring of the NUTRIMUM trial participants’ infants suggested that micronutrient supplementation during pregnancy could also positively impact neuro-behavioral development, showing marked improvements compared to infants exposed to traditional antidepressant medication.
Overall, the studies underscore micronutrients’ potential to improve antenatal depression safely and effectively, setting the stage for further research to solidify these findings and explore broader applications in perinatal mental health.
Contributors to this research, such as Dr Hayley Bradley, recognize the importance of these findings to maternal and child health.

FAQ Section
What is antenatal depression?
Antenatal depression is a form of clinical depression that can affect women during pregnancy. It can have significant effects on the mother’s health, birth outcomes, and the child’s developmental trajectory.
How does poor nutrition contribute to antenatal depression?
Poor nutrition can lead to deficiencies in essential nutrients, which have been linked to increased risks of developing mental health challenges, including depression during pregnancy.
Can changing diet during pregnancy help improve antenatal depression?
Improving diet by increasing the intake of essential nutrients and reducing consumption of ultra-processed foods during pregnancy may have beneficial effects for the mental health of the mother and the child. However, dietary changes alone may not be sufficient for all women, and additional supplementation might be recommended.
What are the benefits of micronutrient supplementation during pregnancy?
Micronutrient supplementation has shown promise in improving overall psychological functioning, enhancing sleep, and daily function, and may improve mental health outcomes for both the mother and the child.
Is micronutrient supplementation safe during pregnancy?
The studies and trials mentioned have not reported any adverse side effects associated with micronutrient supplementation during pregnancy, suggesting it is a safe intervention for both mother and infant. However, it is essential to consult with a healthcare provider before starting any supplementation.
