ZINC is such a common deficiency because it’s hard to get enough through food. Here are some common signs to look out for and foods to increase in the diet.
Zinc is essential for immune function, wound healing, taste, smell, and growth, so when you don’t get enough, your body often sends out some pretty clear distress signals.
Common signs and symptoms of zinc deficiency include:
• Weakened immune system – you get sick more often or take longer to recover from colds/infections.
• Slow wound healing – cuts, scrapes, and skin injuries take longer to close up.
• Hair loss (thinning or shedding) – zinc plays a role in hair follicle health.
• Loss or reduced sense of taste and smell – food may taste bland or strange.
• Skin problems – dry, rough, or scaly skin; sometimes a rash around the mouth, chin, or hands.
• Poor appetite – you may lose interest in eating.
• White spots or ridges on nails – not always zinc-specific, but can be linked.
• Fatigue and low energy – due to its role in cell metabolism.
• Delayed growth or puberty – more common in children and adolescents.
• Eye issues – night vision problems or sensitivity to light.
• Mood changes – irritability, depression, or difficulty concentrating.
