The role of Zinc in the body

Although it is present in tiny amounts in our body, zinc is undeniably a pillar of our overall health. It is a trace element necessary for the metabolism of proteins, carbohydrates and lipids.

Ensuring adequate intake, whether through food sources or judicious supplementation, is essential to benefit from its many virtues. At every stage of our lives, it is imperative to ensure this balance to maintain optimal health. If you are unsure about your consumption, do not hesitate to seek the advice of a specialist.

This essential trace element plays a key role in the orchestration of our biological functions. At the heart of our immune system, it acts like a conductor, ensuring a rapid and effective response to pathogens. In addition, it is the silent accomplice of our skin, actively participating in the healing process and cell regeneration. On the metabolic level, it is involved in the synthesis of proteins, carbohydrates and lipids, thus supporting the smooth running of essential enzymatic reactions.

But that's not all: it also watches over our vision, playing a preventive role against certain eye diseases. At the neuronal level, its presence influences neurogenesis and synaptic plasticity, essential for cognition and memory. Finally, as a pillar of reproductive health, it is involved in sperm production in men and hormonal regulation in women.

The benefits of Zinc

Recognized for its remarkable properties, it strengthens and regulates our immune system, providing a strong barrier against many infections and protecting cells against oxidative stress.

At the same time, its contribution to collagen synthesis makes it invaluable in the wound healing process. As a key element in protein synthesis, zinc also facilitates the metabolism of carbohydrates and lipids, ensuring optimal nutrient absorption.

Beyond these metabolic functions, it watches over our vision by protecting against diseases such as age-related macular degeneration. On the cognitive level, its ability to support neurogenesis is of paramount importance for memory and cognition.

To top it all off, its anti-inflammatory nature soothes skin problems, while it also plays a vital role in maintaining reproductive health. It also has an antioxidant action because it allows the production of prostaglandins thanks to polyunsaturated fatty acids such as omega 3 .

Incorporating zinc into our daily routine therefore proves to be a wise choice for general well-being.


Zinc Deficiency: Signs and Consequences

Zinc deficiencies, although often subtle, can have significant consequences on our health.

One of the first signs of a deficiency can be a weakened immune system, making the individual more susceptible to common infections. This weakness is often accompanied by problems with wound healing, with wounds taking longer to heal without optimal levels of this trace mineral. On the skin, rashes or spots may appear, revealing the importance of this trace mineral for skin health.

Zinc deficiency in athletes mainly results in a decrease in testosterone levels, a crucial hormone in the field of bodybuilding. This hormone plays an essential role in stimulating muscle growth, maintaining muscle mass and providing energy to resist fatigue during training. In addition, testosterone promotes muscle and nerve recovery after exercise. Thus, zinc supplementation proves beneficial in preventing the decline in sports performance.

Reproductively, it can impact sperm health in men and the menstrual cycle in women.

And finally, on a mental level, it can lead to concentration and memory problems.

It is therefore essential to monitor your zinc consumption to avoid these problems and maintain physical and mental balance.


Recommended nutritional intakes

Zinc intake is of paramount importance for the proper functioning of the body. According to general recommendations, an adult man should consume an average of 15 mg per day, while an adult woman should have 12 mg.

These recommendations may vary depending on specific needs: for example, pregnant or breastfeeding women may need a slightly higher dose to support fetal or infant growth. For children, the recommended intake ranges from 5 mg to 10 mg depending on their age and stage of development.

However, it should be noted that overconsumption of zinc can be harmful. Excessive ingestion, greater than 40 mg per day for an adult, could lead to adverse effects, such as gastrointestinal disturbances or inhibition of the absorption of other essential minerals such as copper.

It is therefore essential to supplement with the correct recommended dosage to benefit from the virtues of zinc without having side effects.

In short, while zinc is crucial to our health, as with any nutrient, moderation is key. It is always recommended to consult a healthcare professional before starting any supplementation, to determine the correct dosage and ensure that it is appropriate for individual needs.


Zinc as a dietary supplement

Zinc, as a dietary supplement, is gaining popularity for its ability to address nutritional deficiencies and boost overall health.

Many people turn to these supplements, especially when their diets don't provide enough of this essential trace mineral. This is the case for vegetarians and vegans, whose diets may be lacking in certain rich sources of zinc such as red meat.
Likewise, certain medical conditions or periods of life, such as pregnancy, may increase zinc requirements.

Choose good quality supplements, free of unnecessary additives and from reliable sources, to ensure optimal absorption and minimize the risk of side effects.


The benefits of Zinc for women

Often cited for its overall health properties, zinc is also of particular importance for the well-being and physiological balance of women.

First of all, it plays a vital role in regulating the menstrual cycle. It is involved in the production and release of hormones, ensuring a regular cycle and promoting healthy ovulation. Additionally, during menstruation, some women may experience a slight zinc deficiency due to blood loss, hence the importance of ensuring a regular intake.

During pregnancy, zinc requirements increase to support optimal fetal development. It plays a crucial role in DNA synthesis, cell division, and the formation of the baby's nervous system. A deficiency during this time can impact the health of both mother and child.

Zinc also has beneficial properties for the skin. It can help reduce skin inflammation, such as hormonal acne, which can sometimes be exacerbated by hormonal fluctuations in women.

Its benefits do not stop there since it plays a role on the emotional level by acting on the regulation of mood. Some researchers suggest that it could have a stabilizing effect, particularly during premenstrual periods when some women are subject to mood swings.

Finally, it supports the health of hair, nails and skin, elements often affected by hormonal imbalances. Its contribution to protein synthesis ensures healthy and robust growth of these tissues.

Whether for its role in hormonal regulation, skin health, or emotional well-being, zinc is a valuable ally for women's overall health at every stage of their lives.
