Vitamin A supplementation is given initially and then at what interval?

• A. Every 3 months
• B. Every 6-12 months
• C. Every 2 years
• D. Daily

Answer: (B)

Vitamin A supplementation scheduling depends on how long the vitamin’s protective effects last in the body. After an initial dose, the goal is to keep liver stores adequate so immunity and vision protection don’t drop between doses. Since vitamin A is stored in the liver and that protection wanes over several months, the follow-up dose is spaced out to about six to twelve months. This interval keeps the benefits consistent without overdoing supplementation. Dosing every few weeks or daily would be unnecessary and impractical, while waiting years would leave children at risk for deficiency.
