What is the recommended dosage of selenium supplementation in term neonates weighing 3-10 kg with normal organ function?

• A. 1 mcg/kg/day
• B. 1.5 mcg/kg/day
• C. 2 mcg/kg/day
• D. 3 mcg/kg/day

Answer: (C)

Selenium is essential for the antioxidant enzymes that protect cells, including glutathione peroxidase. In term neonates, especially when receiving nutrition support, the goal is to provide enough selenium to prevent deficiency without risking toxicity. For term neonates with normal organ function, about 2 mcg per kilogram of body weight per day is the standard prophylactic dose. This amount supports adequate selenoprotein activity across a 3–10 kg infant, giving roughly 6–20 mcg per day depending on weight, which is sufficient to meet needs without excess. Higher doses are usually reserved for preterm or stressed infants who have greater oxidative challenges, while lower doses may not reliably prevent deficiency in those on long-term support.
