What is the relationship between copper and estrogen? | Masterjohn Q&A Files #322

Question: What is the relationship between copper and estrogen? Short Answer: Estrogen moves copper from the mother's bloodstream to the fetus during pregnancy. Its action at the intestines is poorly understood but I believe estrogen and progesterone interact to promote intestinal copper absorption. Maintaining pregnancy-level hormones while not pregnant poses a risk of promoting too much absorption of copper from food without transferring it to a growing baby. Copper status should be monitored when using supplemental hormones to avoid copper toxicity. This is a clip from a live Q&A session open to CMJ Masterpass members.
