Study on Supplements and Pregnancy

A new study shows that supplements of DHA (omega-3 fatty acid found in fish oil), vitamin D, folic acid (folate), and iodine have a positive impact on the fetus in pregnant women. Researchers reviewed randomised controlled trials from 2000 to 2012 and found a unified conclusion.

Omega 3, DHA during pregnancy

Supplementing with DHA during pregnancy and breastfeeding leads to:

• A reduced risk of premature birth
• A reduced risk of low birth weight, small head circumference, and short stature
• May improve the baby’s visual acuity
• May increase hand-eye coordination in the baby

Vitamin D during pregnancy

Supplementing with vitamin D during pregnancy:

• Supports normal bone development
• Supports normal brain development

Folic acid or folate during pregnancy

Supplementing with folic acid/folate during pregnancy:

• Contributes to the development of the spinal cord, brain, and skull

Iodine during pregnancy

Supplementing with iodine during pregnancy is:

• Important for thyroid development, which supports normal brain and nervous system development during pregnancy, affecting the child’s future development.

Supplements during pregnancy

The researchers' conclusion:

“Supplements within the recommended safe levels for pregnant women can prevent many brain and nervous system-related disorders in those with deficiencies, and may also contribute to improved brain development and function in the offspring.”

It is important to note that nutrients should primarily come from food, but if one is neglecting their diet or has absorption issues, supplements can play a role. Nutrient intake during pregnancy and breastfeeding is especially important. Daily doses should not be exceeded, and neither supplements nor specific pregnancy supplements should be used as a substitute for a varied diet.
