Too much of a “good” supplement is still too much.
Zinc is essential—for immunity, hormone function, and wound healing. But more isn’t better.
High, chronic zinc intake can deplete copper, a mineral your body needs for:
→ red blood cell production
→ nervous system function
→ iron metabolism
Over time, that imbalance can show up as fatigue, anemia, or even neurological symptoms.
The threshold matters:
40 mg/day is the established upper limit for adults. Above that, risk increases.
Most people supplement zinc without ever checking their levels—or balancing it with copper.
That’s the gap.
Your body doesn’t run on single nutrients. It runs on relationships between them.
Understanding those relationships is what turns “taking supplements” into something that actually works.
