Cyclic Variation in Micronutrient Concentrations and Plasma Volume
Completed
Conditions studied: Plasma Volume, Micronutrients, Menstrual Cycle
In brief
The overall goal of this study is to examine the influence of the menstrual cycle on micronutrient concentrations and plasma volume in healthy, reproductive-age women with regular cycles. The investigators aim to quantify changes in micronutrient biomarker concentrations (zinc, copper, iron, and vitamin A) and plasma volume across the menstrual cycle in healthy women.
