I took a zinc tally taste test recently, and it tasted like water, apparently indicating a zinc deficiency. I've been dealing with dysbiosis/leaky gut for 7 or 8 years now, so my zinc could be depleted or not absorbing properly. We also have acidic well water and copper pipes (though we do run the water 3 minutes before drinking it), so copper could be outcompeting zinc for absorbtion.
After some research and discussion I'm convinced that I need to proceed with supplementation carefully. I'd like to get some tests done to see where I stand now, especially with zinc and copper.
Travis Culp suggested that serum levels of minerals are misleading and very poorly reflect the body's mineral pools.
What is a reliable way to gauge the body's mineral pools? I've heard strikes against serum testing and hair mineral analysis, but I imagine nothing's perfect. I'd also like to avoid breaking the bank. Suggestions?
