What are the disadvantages of not taking vitamims during third trimester?

Not taking vitamins during the third trimester can lead to deficiencies in essential nutrients, which are critical for fetal development and maternal health. This can increase the risk of complications such as low birth weight, preterm birth, and developmental issues in the baby. Additionally, inadequate vitamin intake may weaken the mother's immune system and lead to fatigue or other health problems. Overall, it can compromise both the mother's and the baby's well-being during this crucial stage of pregnancy.
