Zinc is an indispensable mineral that plays a fundamental role in the regeneration of cellular tissues and in the synthesis of DNA. It is an active part of the enzymes involved in the metabolism of fats, proteins and carbohydrates.
Among its many functions, the following can be highlighted:
- It intervenes in metabolic processes at the digestive and nervous levels.
- Its immune function helps the body to adapt to seasonal climate changes.
- It has a key role in protein synthesis.
- Facilitates the wound healing process.
- Neutralizes free radicals and protects skin cells.
- It is involved in stabilizing the structure of insulin, which maintains the balance of glucose concentration in the blood .
Symptoms of Zinc Deficiency
Zinc deficiency is clinically associated with both dermatological and immunological manifestations:
- Delayed wound healing
- Hair loss (Alopecia)
- Loss of appetite
- Frequent infections
- Hypogonadism in males
- Skin lesions
- White spots on nails
- Diarrhea
- Impaired taste sensation (Hypogeusia)
- Growth retardation in children

Properties And Benefits Of Zinc
Adequate zinc intake helps the body improve its ability to relieve inflammation , but it also benefits the body in multiple ways, including those discussed below.
Helps The Proper Functioning of The Immune System
This mineral is essential for immune cells to function properly. Therefore, zinc supplements can improve the body’s immune response , and protect cells against oxidative damage. (Mayo Clinic)
Its contribution at the immunological level is due to its role in the development of T lymphocytes, which in turn stimulate T cells, which are responsible for fighting infections. In fact, according to certain clinical trials, zinc tablets can reduce the duration of the common cold by around 33%.
Promotes Wound Healing
Zinc has positive effects on wound healing as it promotes collagen synthesis . For this reason, many health specialists use it together with vitamin C, to accelerate the healing of pressure ulcers, which are known as bedsores.
It Has Anti-Inflammatory Action
Some types of inflammation are related to our DNA. Zinc works as a modulator of the genes that cause inflammation , so it can change the way they are expressed.
On the other hand, since inflammation is related to oxidative stress (there is an imbalance between free radicals, which can reason cell harm, and antioxidants), zinc as an antioxidant allows to balance the two sides.
Improves Cognitive Function
The relationship between Alzheimer’s and trace elements such as zinc is still under investigation. It seems that maintaining stable levels of this mineral may be key to relieving symptoms or preventing Alzheimer’s.
Zinc is recommended that pregnant women have a diet rich in zinc in addition to treatment with folic acid and iron, to achieve adequate fetal development. It has been shown that zinc deficiency negatively affects neuronal maturation , also affecting other parts of the body, where learning and the entire cognitive process are impaired.
