Zinc Deficiency? How This Overlooked Mineral Impacts Everything From Acne to Fertility
Zinc is an essential trace mineral that plays a vital role in immune function, skin repair, hormone regulation, and more. Despite its importance, zinc deficiency is surprisingly common — especially in vegetarians, athletes, and older adults.
In this guide, we explore how zinc supports the body, which forms are best absorbed, and how to use it effectively.
Why Zinc Matters
Zinc is involved in over 300 enzymatic processes and is critical to several systems:
- 🛡️ Immune response
- 💆 Skin regeneration
- 🧬 DNA repair
- 🧠 Mood and cognition
- ⚖️ Hormone balance
Even mild zinc deficiency can impair these vital processes, making supplementation a smart preventive strategy.
