$1 spent $17 benefits
Our cost to reach one child with two doses of vitamin A during their most vulnerable years (ages 6-59 months) is approximately $0.25 cents per year. Two doses per year can alleviate vitamin A deficiency (VAD) in children under five, a solution proven to reduce overall child mortality by about 24% in at-risk populations. Join us in our effort to reach at-risk children worldwide with essential nutrients.

In 2008, a panel of world-class economists assembled by the Copenhagen Consensus analyzed forty solutions to ten of the world's greatest global development challenges.
The result? The panel ranked micronutrient supplementation for undernourished children the #1 priority.
1: Micronutrient supplements for children (vitamin A and zinc) Malnutrition
2: The Doha development agenda Trade
3: Micronutrient fortification (iron and salt iodization) Malnutrition
4: Expanded immunization coverage for children Diseases
5: Biofortification Malnutrition

Notes:

  • Liver stores vitamin A for about 2 years – vitamin D for about 4 months
  • Lack of consensus on Vitamin A half life: ranges from 50-300 days
  • Serum level of vitamin A is not a good measure – as serum level is regulated
