Yes, pregnant women can drink orange juice, and it can be beneficial when consumed in moderation. Orange juice is rich in essential nutrients like vitamin C, folate, calcium, iron, and antioxidants, which support the immune system, help fetal brain development, improve hydration, and aid digestion during pregnancy. However, it is recommended to limit intake to about 200 ml per day to avoid potential side effects such as tooth enamel damage, heartburn, excessive sugar intake, and gastrointestinal discomfort. Pregnant women with conditions like ulcers or acid reflux should be cautious. Drinking orange juice at the right time—1-2 hours after meals—and avoiding immediate consumption with milk is advised for optimal benefit and minimal side effects.
