Zinc Deficiency: 8 Symptoms, 5 High-Risk Groups and How to Correct It Safely
Zinc Deficiency: Small Signs That May Point to a Problem
Zinc is a mineral we need in small amounts, yet it is involved in hundreds of enzymes. When levels fall, signs can appear that seem minor, such as hair loss or frequent colds. This article explains the symptoms of zinc deficiency, who is most at risk and how to correct it safely.
Why Does the Body Need Zinc?
The immune system needs zinc for the growth and function of its cells, and zinc also supports wound healing, taste and smell, healthy skin, hair and nails, and normal bones. The body does not store much zinc, so we need a regular supply from food. Read more in our article on zinc benefits.
8 Symptoms That May Suggest Zinc Deficiency
- Frequent infections and weaker immunity.
- Slow wound healing.
- Hair loss.
- Loss of appetite.
- Reduced sense of taste or smell.
- Diarrhoea.
- Skin problems and sores around the mouth.
- Delayed growth in children.
These symptoms have many other causes, so do not self-diagnose zinc deficiency – see your doctor.
5 Groups at Higher Risk of Zinc Deficiency
- Vegetarians and vegans: grains and legumes contain compounds that reduce zinc absorption.
- Pregnant and breastfeeding women: because needs increase.
- People with digestive conditions: such as Crohn’s or coeliac disease, or after stomach or bowel surgery.
- People who drink alcohol heavily.
- Older adults: who may eat less and absorb less.
How Is Zinc Deficiency Diagnosed?
Zinc can be measured in the blood, but the test does not always reflect the body’s stores accurately. Doctors therefore combine symptoms, diet history and overall health with test results.
Food Sources of Zinc
- Oysters – the richest source.
- Red meat and poultry.
- Legumes, nuts and seeds such as pumpkin seeds.
- Whole grains and dairy products.
Zinc Deficiency vs Iron Deficiency
Some symptoms overlap, such as tiredness and hair loss. Iron deficiency is linked more with anaemia, pale skin and breathlessness on exertion, while zinc deficiency is linked with poor taste, slow wound healing and frequent infections. Both can occur together in vegans and pregnant women, so doctors order the right tests before deciding on treatment.
Tips to Improve Zinc Absorption
- Soaking legumes and grains before cooking reduces compounds that block absorption.
- Do not take iron or calcium supplements at the same time as zinc.
Correcting Zinc Deficiency with Supplements
Daily needs are 8 mg for women and 11 mg for men, rising in pregnancy and breastfeeding. Many supplements contain 15–25 mg. One example is MinaVit Vitamin C Zinc, which combines 15 mg zinc with 1000 mg vitamin C in an effervescent tablet. To understand this combination, read our guide to vitamin C and zinc.
Beware of Too Much
The adult upper limit is 40 mg a day from all sources. High doses over long periods can cause copper deficiency, weaker immunity, nausea and stomach upset. Zinc also reduces the absorption of some antibiotics, so separate them by two hours.
