Fish oil is an important supplement to take during pregnancy, but it is important to distinguish between the two types of fish oil supplement. Omega-3 supplements are safe to take during pregnancy and can benefit both mother and baby. However, cod liver oil is not safe during pregnancy because it contains retinol, which can be harmful to the baby.
Fish oil supplements are a good source of long-chain omega-3 fatty acids, which are important for the baby's brain and eye development. They may also help to protect against heart disease in later life. It is recommended that pregnant women eat one to two portions of oily fish per week, but if this is not possible, a daily omega-3 supplement can be beneficial.
It is important to choose a high-quality fish oil supplement that does not contain retinol vitamin A and is suitable for pregnant women. It is also advisable to avoid high-dose supplements and to check the amount of DHA and EPA in the supplement.

Fish oil is safe during pregnancy, but not cod liver oil
Fish oil is a great source of omega-3 fatty acids, which are essential for the development of the baby's brain and eyes. Omega-3 fatty acids also help to reduce the risk of preeclampsia, low birth weight, and preterm birth. However, it is important to choose a high-quality fish oil supplement that has been purified to remove any environmental toxins, such as mercury.
On the other hand, cod liver oil is not recommended during pregnancy because it contains high levels of vitamin A, which can be harmful to the baby. Vitamin A is a fat-soluble vitamin that can accumulate in the body and reach toxic levels. While cod liver oil has some benefits, such as supporting immune health and healthy skin, it is best to avoid it during pregnancy due to the potential risks to the baby.
It is always advisable to consult with a healthcare professional before taking any supplements during pregnancy to ensure the safety and appropriateness of the specific supplement for the individual's needs.

Omega-3 fatty acids are essential for the baby's brain and eye development
Omega-3 fatty acids are essential for a baby's brain and eye development. They are one of the essential dietary nutrients, and their important roles include providing the fatty acid docosahexaenoic acid (DHA) for nervous tissue growth and function. DHA is abundantly present in the human brain during development and is found in maternal breast milk. It is also added to some infant formulas.
Several clinical studies have shown that omega-3 fatty acids are essential for normal infant vision development. According to a Pediatrics journal analysis, healthy preterm infants fed DHA-supplemented formula showed significantly better visual acuity at 2 and 4 months of age compared to similar infants fed formula without the omega-3 supplement. In another study, infant girls whose mothers received DHA supplements from their fourth month of pregnancy until delivery were less likely to have below-average visual sharpness at 2 months of age.
Additionally, two randomised controlled trials (RCTs) reported improvements in problem-solving at 9 months of age and hand-eye coordination at 30 months of age in children whose mothers had taken omega-3 fatty acid supplements during pregnancy.
While there is strong evidence for the benefits of omega-3 fatty acids during pregnancy, it is important to note that excessive amounts may be harmful. Most experts believe that the ratio of omega-6 to omega-3 fatty acids in a healthy diet should be 4-to-1 or lower. The US government's safe daily limit for Omega-3 is 4,000 mg, while the EU level is 5,000 mg.

Fish oil helps prevent pre-eclampsia, low birth weight, and preterm birth
Fish oil is considered beneficial during pregnancy, and studies have shown that it is safe for both mother and baby. It is thought to help prevent pre-eclampsia, low birth weight, and preterm birth.
Pre-eclampsia is a serious condition that can occur during pregnancy, characterised by high blood pressure and damage to organ function. It can be life-threatening for both mother and baby. A meta-analysis of 14 comparisons demonstrated that n-3 fatty acid supplementation, including fish oil, played a protective role against the risk of pre-eclampsia. Additionally, some individuals have shared their positive experiences with using fish oil during pregnancy to prevent pre-eclampsia.
Low birth weight is associated with an increased risk of health complications for newborns. Studies have shown mixed results regarding the impact of fish oil supplementation on birth weight. While some research suggests a reduced risk of low birth weight, other studies have found no significant effect. However, one study did find that babies born to mothers who took fish oil supplements had higher mean birth weights than those in the control group, although the clinical significance of this difference is questionable.
Preterm birth, when babies are born before 37 weeks of gestation, is a leading cause of newborn deaths and can result in long-term health issues for survivors. Omega-3 fatty acids, found in fish oil, have been shown to reduce the risk of preterm birth. A Cochrane review of 70 randomised trials found that increasing omega-3 intake during pregnancy lowered the risk of preterm birth by 11%, and early preterm birth (less than 34 weeks) by 42%.
While fish oil supplementation during pregnancy is generally considered safe and beneficial, it is always advisable to consult with a healthcare professional before starting any new supplement regimen. Additionally, it is important to note that most randomised trials of prenatal marine oil supplementation have been conducted in high-income countries, so the findings may not be generalisable to all populations.

Fish oil may help prevent and manage neonatal hypoxic ischemic brain injury
Fish oil is a rich source of omega-3 fatty acids, including docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). DHA is the most abundant omega-3 fatty acid in the adult mammalian brain, constituting over 30% of the total phospholipid content of cellular membranes.
Neonatal hypoxic-ischemic brain injury is a serious condition that can lead to long-term cognitive impairments and brain damage. The condition results from a lack of oxygen and blood flow to the brain, causing neuronal cell death and inflammation. Several studies have demonstrated the neuroprotective effects of DHA and EPA in animal models of neonatal hypoxic-ischemic brain injury.
For instance, in neonatal mice models, DHA administered immediately after HI injury reduced brain damage and improved neurological outcomes. Similarly, in neonatal rat models of asphyxia, DHA post-treatment combined with brief delayed hypothermia improved sensorimotor function and reduced tissue injury.
Zhan et al. found that omega-3 PUFA acid supplementation (DHA + EPA) in pregnant female rats from the second day of pregnancy until 14 days after giving birth provided long-term neuroprotection against neonatal hypoxic-ischemic brain injury. This protection was achieved by attenuating microglia-mediated inflammatory responses and inhibiting neuronal cell death.
In summary, DHA and EPA found in fish oil show promising results in preventing and managing neonatal hypoxic-ischemic brain injury. When administered before or after HI injury, these omega-3 fatty acids reduce brain damage, improve neurological function, and inhibit inflammatory responses. However, further research is needed to confirm these findings and determine optimal dosages and treatment protocols.

Fish oil may help reduce the risk of infant allergies
Fish oil is a rich source of omega-3 polyunsaturated fatty acids (PUFAs), such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These fatty acids are known for their anti-inflammatory properties.
During pregnancy, a mother's diet influences immune-mediated diseases in her children. A mother's fetus is subject to her nutrients, microbes, environmental exposures, and medications — all of which can have lifelong effects on the child.
Results from a meta-analysis show that a mother's fish oil supplementation during pregnancy may reduce allergies in her children. Specifically, maternal supplementation with fish oil may reduce children's sensitization to food allergens.
In a randomized controlled trial, 145 pregnant women were included in a study. The women were given either 1.6 g of EPA and 1.1 g of DHA or a placebo from the 25th gestational week to an average of 3-4 months of breastfeeding. The period prevalence of food allergies was lower in the omega-3 group (2%) compared to the placebo group (15%).
In another study, 420 infants of high atopic risk were split into groups receiving either fish oil supplements containing 280 mg DHA and 110 mg EPA or control oil supplements daily from birth to 6 months. The infants receiving fish oil supplements had significantly lower allergic responses to dust mites and milk protein.
In summary, fish oil supplementation during pregnancy and lactation may decrease the risk of infant allergies.
