Zinc & Immune Aging

Does zinc influence longevity?

Yes. Adequate zinc supports immune resilience, wound healing, and protection against infections common in aging.

Explanation

Zinc is essential for immune cell development, DNA repair, and antioxidant defense. Deficiency impairs immune responses, delays wound healing, and increases infection risk, especially in older adults.

Research shows that zinc supplementation in deficient individuals improves immunity and reduces the incidence of respiratory infections. Zinc also supports antioxidant enzymes such as superoxide dismutase, which help control oxidative stress. However, excessive zinc intake can interfere with copper absorption, underscoring the importance of balanced intake.

Practical Emphasis: Incorporate zinc-rich foods like seafood, legumes, seeds, and nuts. Periodic testing may be helpful in older adults or those with dietary restrictions to ensure adequacy.

Takeaway (Action Tip)

Consume zinc-rich foods regularly and avoid unnecessary high-dose supplementation.
