Attempted direct supplementation of an entire population to control scurvy has not been effective in refugee camp trials. Problems include distributing tablets at least once a week to large refugee populations in unorganized camps. Compliance has also been low, and in some instances tablets were accumulated and sold in the market. A strong education component is needed to convince users of the importance of vitamin C as well as a well-established network for its distribution. However, the controlled supplementation of pregnant and lactating women at mother-baby clinics in many camps and is one way of targeting a group at risk.
