Supplements containing EPA may not be recommended for infants or small
children because they upset the balance between
DHA and EPA during early development. Pregnant women should talk to their doctor before taking fish oil supplements.
Fish oil capsules may cause minor side effects, such as loose stools, abdominal discomfort, and belching. In addition, they may prolong bleeding time slightly. If you take blood-thinning medication, talk to your doctor before taking fish oil.
