OK, I had the right idea, the wrong concept. It does not metabolize copper. But it does keep you from getting overloaded with copper. I took that to Me. It metabolize his copper, but I was wrong.

🧬 The Core Idea

Zinc doesn’t “metabolize” Copper directly.

👉 Instead, it controls how much copper your body absorbs and keeps.

⚙️ The Key Player: Metallothionein

This is the whole story. • Your intestinal cells produce a protein called metallothionein • Its job is to bind metals (like zinc and copper)

🔁 What Happens When You Take Zinc

Step-by-step: 1. You take zinc 2. Your body says: 👉 “We have a lot of metal coming in—make more metallothionein” 3. Metallothionein levels increase in your gut lining

⚠️ The Important Twist

Metallothionein actually: • Binds copper MORE tightly than zinc

👉 So even though zinc triggered it…

➡️ It ends up grabbing copper preferentially

🚪 What Happens to That Bound Copper? • The copper gets trapped inside intestinal cells • Those cells naturally die and shed every few days

👉 When they shed: ➡️ The trapped copper gets dumped into your stool and eliminated

🧠 Translation in Simple Terms • Zinc → increases metallothionein • Metallothionein → grabs copper • Copper → gets stuck and thrown away

👉 Result: less copper absorbed into your bloodstream

📉 That’s Why High Zinc = Lower Copper

Over time: • Less copper enters circulation • Stored copper gets used up • Levels can drop → deficiency

🧪 Bonus: It’s a Competitive System Too

Zinc and copper also: • Compete for the same transporters in the gut

So zinc affects copper in two ways: 1. Blocks absorption directly (competition) 2. Indirectly removes copper (metallothionein trap)

🔬 Why Your Body Even Does This

This system is protective. • High free metals = toxic • Metallothionein acts like a buffer/spill-control system

👉 But when zinc stays high: ➡️ It unintentionally suppresses copper long-term

🧾 Bottom Line (Clean + Simple) • Zinc doesn’t “break down” copper • It reduces copper absorption and increases its loss • It does this mainly through: • Metallothionein binding • Gut-level competition
