For children who are receiving high dose Vitamin A capsules twice yearly is there any concern about Vitamin A toxicity if they are receive Micronutrient Powder (MNP), which also contain Vitamin A?

There is no risk of toxicity. The dose of Vitamin A in Micronutrient Powder (MNP) is formulated to help the child meet the daily Vitamin A requirement. When WHO initiated the high dose capsules, they did not stipulate that the child receiving the supplement should not eat food containing Vitamin A. Indeed they recommended an age appropriate diet which would contain all micronutrients, including Vitamin A.
