8 Subtle Signs of Zinc Deficiency Experts Want You to Know

Key Points:

• Zinc is an essential mineral that supports immune function, wound healing, and fetal development, with deficiency being rare in the U.S. but more common in people with eating disorders, substance abuse, gastrointestinal issues, vegetarians, and vegans.
• Common symptoms of zinc deficiency include slow-healing wounds, hair loss (linked to conditions like alopecia areata), and acne, with research showing lower zinc levels in those affected.
• Zinc deficiency is associated with increased susceptibility to chronic diseases such as pneumonia and diabetes due to its role in immune response and inflammation control.
• Declining zinc levels with age can contribute to vision loss, particularly age-related macular degeneration, and supplementation may help prevent this, though excessive zinc intake has risks.
• Other signs of zinc deficiency include loss of taste and smell, hearing problems like tinnitus, and stunted growth in children and adolescents, highlighting zinc's importance in sensory functions and development.
