Why Zinc Deficiency Is More Common Than You Think
Zinc is the second most abundant mineral in the body after iron and is vital for the proper function of every cell, tissue, and organ. Yet, up to one in three people may not be getting enough — often without realising it. Zinc deficiency frequently goes undiagnosed because its symptoms can mimic other conditions.
Even if your diet includes zinc, factors like ageing, stress, vegetarian or high-phytate diets, poor digestion, and chronic illness can all impair absorption and increase your risk of deficiency.
Signs You May Be Low in Zinc
-
Frequent infections or slower healing
-
Brain fog and poor concentration
-
Low mood or disrupted sleep
- Skin problems, hair loss or rashes
- Decreased sense of taste or smell
- Digestive issues or food sensitivities
- Reduced libido or hormone imbalances
- Occasional loose stools or leaky gut
Zinc isn’t stored in the body, so consistent daily intake is essential — especially for people over 60 or those in higher-risk groups like vegetarians, pregnant or nursing women, and those with digestive disorders.
Zinc’s Role in Whole-Body Health
Zinc supports over 300 enzymatic reactions in the body and plays a part in the structure or function of around 3,000 proteins. It is essential for:
-
Immune health and inflammation regulation
-
DNA repair and healthy cell division
- Hormonal balance and adrenal function
- Wound healing and skin repair
- Bone health and mineralisation
-
Vision, taste, smell and brain function
-
Protection against oxidative stress and ageing
Too much zinc, however, can be just as harmful as too little — disrupting copper balance, immune function, and even hearing and taste.
