Multinutrient-fortified juices improve vitamin D and vitamin E status in children: a randomized controlled trial.

What Was Tested

This randomized controlled trial looks at Vitamin D, K2, Magnesium and Zinc.

Changes in 25(OH)D, α-tocopherol, retinol, and parathyroid hormone concentrations were examined.

Covariates included sex, age, race/ethnicity, body mass index, and baseline 25(OH)D, α-tocopherol, retinol, or parathyroid hormone levels.

Who Took Part

According to the abstract, 176 children were involved.

By PubMed's age tags, the people studied were children, both men and women.

One hundred eighty participants (aged 8.04±1.42 years) were recruited at Tufts (n=70) and Boston University (n=110) during 2005-2006.

How the Study Was Run

The researchers set it up as a randomized and double-blind study.

Random assignment meant chance, not the researchers, decided who got Vitamin D, K2, Magnesium and Zinc and who got the comparison, which limits bias.

As a double-blind Vitamin D, K2, Magnesium and Zinc study, the assignments were hidden from both participants and investigators until the end.

A 12-week randomized, double-blind, controlled trial.

What Was Measured

Covariates included sex, age, race/ethnicity, body mass index, and baseline 25(OH)D, α-tocopherol, retinol, or parathyroid hormone levels.

Multivariate models and repeated measures analysis of variance tested for group differences with pre-post measures (n=141).

The authors tagged it with the keywords Multinutrient juice, Vitamin D and Vitamin E.
