Zinc is one of the most important minerals for overall health. Like calcium, it plays a vital role in keeping the body functioning properly. Zinc is found in every tissue and body fluid and is especially concentrated in the brain. It is also known for its strong antioxidant properties, helping protect the body from damage.
While zinc is naturally present in many foods, the body does not store it. This means it needs to be consumed regularly through diet or supplementation to maintain healthy levels.
Why Zinc Matters
Zinc supports a wide range of essential body functions, including:
-
Activating over 300 enzymes involved in metabolism, digestion, nerve function, and more
-
Supporting the immune system, helping the body adapt to seasonal changes
-
Assisting in wound healing and maintaining healthy skin
-
Playing a role in protein production
-
Protecting skin cells from damage while supporting healthy hair and nail growth
-
Supporting brain health and proper nervous system function
-
Contributing to DNA synthesis
-
Promoting growth, development, and healthy cell division
Because zinc is involved in so many processes, not getting enough can have noticeable effects on overall health.
Signs of Zinc Deficiency
Low zinc levels may lead to several health concerns, such as:
-
Reduced concentration, memory issues, or behavioral changes
-
Diminished sense of taste or smell
-
Delayed growth and development
-
Skin irritation or rashes
-
Slow wound healing
-
A weakened immune system and increased risk of infections

-
Seafood such as oysters, crab, and lobster
-
Lean red meats like beef and pork

Poultry including chicken and turkey

Who May Need Extra Zinc?
Some people are more likely to experience zinc deficiency due to dietary habits or health conditions. These groups include:
-
Vegetarians and vegans
-
Pregnant and breastfeeding women
-
Older infants who are exclusively breastfed
-
Individuals with certain blood or kidney conditions

Since zinc absorption varies from person to person and the body does not store it, supplements can be a helpful option for maintaining adequate levels.
