Why You Should Manage Your Copper Status and How to Do It | Mastering Nutrition #26

In episode 26, we continue the series on assessing and managing nutritional status. This time we talk about copper. Copper deficiency can cause anemia that is very difficult to tell apart from iron-deficiency anemia, osteoporosis, histamine intolerance, high cholesterol, and a variety of mental effects resulting from neurotransmitter imbalances. Serum copper and ceruloplasmin are excellent tools for assessing nutritional status, but are confounded by inflammation, birth control, menopausal status, and hormone replacement therapy, making it necessary to look at the diet, lifestyle, digestive problems, and other factors that make copper deficiency plausible. 

I discuss how to protect yourself from the small risk of copper in your drinking water, and why I think many claims about excess copper outside the context of frank toxicity are misleading.

Everything converges on the practical questions of what to do in these situations.
