What This Study Did, in Plain Language
What Was Tested
This randomized controlled trial looks at Copper (Supplement).
Plant-based diets are accepted as healthy, provided that are well-planned and include supplements.
In this context, iron deficiency is a threat, and data from Spanish vegetarians are scarce.
The aim of this study was to determine if a microalgae ω-3 supplement rich in docosahexaenoic acid (DHA) affected iron status in this population.
Who Took Part
PubMed tags the participants as both men and women.
How the Study Was Run
The design is described as randomized, double-blind, placebo-controlled and crossover.
The participants were allocated by chance, so the Copper (Supplement) group and the comparison group should start out alike.
As a double-blind Copper (Supplement) study, the assignments were hidden from both participants and investigators until the end.
The comparison arm used a placebo, so changes seen with Copper (Supplement) could be set against what happens without it.
Each person switched between Copper (Supplement) and the comparison at some point, usually with a gap in between.
Iron biomarkers and nutrient intake (72-h dietary records) were analyzed in 204 usual consumers of lacto-ovo vegetarian (LOV), vegan (VEG), or omnivorous (OMN) diets.
What Was Measured

Our Notes on the Compound
Copper (Supplement): The active site of cytochrome c oxidase is described as containing copper ions that are essential for electron transfer.
