Objective: To acquire the local scientific evidence, to evaluate the effects of micronutrient Sprinkles™ powder, both the nutritional status and haematological values in the vulnerable preschool population, to corroborate the reported benefits of the experiences in other countries.

Question: Will it improve the nutritional status and hematological levels after the home fortification with Sprinkles in children of two child care centres in the city of Medellin, in 2013?

Hypothesis: At the end of intervention, hematologic levels and anthropometric indicators will be better in the intervention group with Sprinkles, compared with the placebo group.

Design: Randomized clinical trial, triple-blind and placebo-controlled.

Participants: Two groups of 50 children each, aged between 5 and 59 months, not anemic or with severe malnourished, full-time assistants to two children's centres that have the same alimentation menu.

Intervention: The daily diet will be supplemented with sprinkles in one of the children's centres and will be compared anthropometric and hematological values before and after with a group receiving the same diet with placebo.

Outcome measures: Nutritional status (anthropometric measures) and haematological values (hemoglobin, ferritin, transferrin and folate).

Inclusion Criteria:

• Assistance to children's centres full day (8 hours).
• Age 5 to 59 months.

Exclusion Criteria:

• Anemia (hemoglobin less than 11 g / dl).
• Current supplementation with a product formulated by a health professional as a part of a nutritional recovery.
• Denial for informed consent signing by parents or legal guardians.
• Diagnosis of severe acute malnutrition by anthropometric measurements.
