Introduction
Zinc is an essential micronutrient and an important active ingredient that our body urgently needs to maintain numerous functions. Despite its importance, the human body cannot produce zinc itself – we rely on intake through our diet. Interestingly, about 17% of people worldwide suffer from zinc deficiency, which can lead to a variety of health problems, such as zinc loss due to diarrhea. Zinc gluconate effect, a well bioavailable form of the trace element, has proven to be particularly effective in regulating zinc levels and promoting well-being. It not only supports the health of skin and hair but also strengthens the immune system and contributes to overall vitality. As with many medications, it is important to be aware of possible zinc gluconate side effects when taking zinc gluconate as a dietary supplement.
What is zinc gluconate?
What is zinc gluconate? Zinc gluconate is a well bioavailable form of the trace element zinc, which is needed for numerous vital functions in the body. It is formed by the reaction of gluconic acid with zinc acetate or zinc oxide and is soluble in water. Zinc is found in many foods, especially in beef and pork, dairy products, as well as in oysters, liver, and legumes. Fruits and vegetables, on the other hand, contain only small amounts of the mineral.
Zinc gluconate is used as a dietary supplement to compensate for a possible zinc deficiency. One capsule of zinc gluconate can provide 30 mg of this important micronutrient. It is particularly important for maintaining skin health, the immune system, and many other biological processes. Due to its good solubility and tolerability, zinc gluconate is also recommended for treating deficiency states and preventing diseases such as diarrheal illnesses, which are often associated with an increased zinc requirement.
If you want to take zinc gluconate as a zinc supplement, you should first obtain a diagnosis and recommendation from a doctor or pharmacist, especially if you are already taking medications. It is also important to dose zinc supplements correctly and store them under the recommended conditions to ensure their effectiveness.
Zinc gluconate: Vital functions for our body
Zinc is a true all-rounder that plays a key role in numerous biological processes. It fulfills structural, regulatory, and catalytic functions that are essential for health and well-being. Nutraceuticals offers products that contain zinc and specifically contribute to supporting health.
Zinc for metabolism
Zinc influences the metabolism of carbohydrates, fats, and proteins and is involved in the regulation of insulin. Studies have shown that zinc supports insulin production in the pancreas and thus plays a role in regulating blood sugar levels. A zinc deficiency has been associated with impaired insulin sensitivity and an increased risk of developing type 2 diabetes (Kamangar et al., 2009). Zinc gluconate can therefore help replenish zinc reserves in the body and optimize glucose metabolism.
Zinc for Defense and Protection
This trace element also plays a central role in protecting the body against harmful free radicals. Zinc helps reduce oxidative stress and supports the immune system in defending against pathogens and maintaining health. These functions are especially important for long-term health and overall well-being.
Zinc for Tissue and Cells
Another important area where zinc plays a role is the formation and maintenance of connective tissue. It is also involved in DNA synthesis and supports cell division, which is essential for tissue regeneration as well as growth and fertility. Zinc also contributes to maintaining good vision.
Zinc and Cell Health
Zinc plays a crucial role in the maintenance and repair of our cells. It is responsible for blood formation and helps maintain the structure of cell membranes and proteins. Zinc is especially important in cell regeneration and growth, such as after injuries. Without sufficient zinc, these processes can be disrupted, impairing the body's healing and regeneration.
Furthermore, zinc supports the body in the production and breakdown of various substances necessary for communication between cells. This not only contributes to cell health but also to the functionality of the nervous system.
Zinc gluconate has particularly high bioavailability, meaning the body can efficiently absorb zinc from this form of supplement. This makes zinc gluconate one of the preferred forms when it comes to quickly and reliably meeting zinc requirements.
Well-being and Good Sleep
Zinc and Stress Reduction
Zinc plays a crucial role in managing stress. It influences the formation of neurotransmitters responsible for communication between nerve cells. In particular, zinc promotes the production of gamma-aminobutyric acid (GABA), a calming neurotransmitter. A zinc deficiency can lead to insufficient GABA production, resulting in increased excitability of nerve cells. This can cause stress, nervousness, and a generally higher susceptibility to strain. Therefore, an adequate zinc level helps reduce stress and enhance overall well-being.
Zinc for restful sleep
GABA not only has a calming effect on the body but also promotes restful sleep. A zinc deficiency can contribute to sleep problems, as the lack of GABA leads to nervousness and restlessness. Conversely, sufficient zinc in the body can help the body relax and improve sleep quality. A stable zinc level thus helps to sleep better, recover faster, and enhance quality of life.
Strong effect on skin and hair
Zinc plays a central role in the health of skin and hair, as it is essential for the regeneration and maintenance of skin structures. Our skin continuously renews itself by forming new skin cells in the inner germ layer, the stratum germinativum. These cells migrate outward to form the top skin layer, which is constantly "worn down." A zinc deficiency can disrupt this regeneration process and lead to skin problems such as rashes, pimples, acne, or delayed wound healing. Insufficient zinc supply can also cause dry, irritated skin areas and a generally weakened skin barrier.
Zinc is also crucial for the formation of the outer skin layer (stratum corneum), which acts as a protective shield against external influences. A zinc deficiency impairs this function and can lead to thinner, less resilient skin.
Hair growth is also significantly influenced by zinc. Zinc supports the metabolism of hair roots, promoting strong, healthy hair. Conversely, a zinc deficiency can lead to brittle, thin, and dull hair. Hair loss and reduced scalp regeneration are also possible consequences. Nutraceuticals for Hair offers specially developed products containing zinc and other important nutrients to promote hair growth and strengthen hair health. These supplements not only support skin and hair regeneration but also ensure a balanced nutrient supply essential for healthy hair and skin.
Practical tips
To prevent skin and hair problems caused by zinc deficiency, the use of zinc supplements or ointments can help, especially with skin inflammations or acute skin conditions. Zinc-containing shampoos and creams support the healing and regeneration of skin and hair. Additionally, a zinc-rich diet should be observed, including foods such as oysters, meat, nuts, and legumes.
Dosage of Zinc Gluconate: 30 mg per day for optimal effect
The correct dosage of zinc gluconate is crucial to benefit from the health advantages without risking side effects. For adults, the recommended daily dose is usually 25 mg to 30 mg of zinc, which often corresponds to one capsule of zinc gluconate. It is recommended to take zinc gluconate with a meal to optimize the absorption of the micronutrient and avoid possible stomach discomfort.
However, it is important to discuss the exact dosage with your doctor or pharmacist, especially if you are already taking other medications or have health issues such as diarrhea or an existing zinc deficiency diagnosis. The correct dose should also be individually adjusted when choosing a zinc supplement to both meet zinc needs and avoid harmful zinc gluconate. Make sure to store the zinc supplement under the recommended conditions to maintain its effectiveness.
How Zinc Strengthens Your Immune System
Zinc is an indispensable micronutrient that plays a crucial role in strengthening the immune system. It supports the activation and growth of important immune cells, helping the body effectively fight pathogens.
Zinc and T Cells
T cells – including T helper cells, T killer cells, and natural killer cells – are responsible for defending against viruses, bacteria, and fungi. They not only eliminate foreign substances but also activate other immune cells and regulate the immune response to prevent an excessive reaction of the body. Adequate zinc supply is essential for the formation and function of these cells, as zinc influences the production of signaling molecules necessary for the growth and activity of T cells. A zinc deficiency can disrupt these processes and weaken immune defense. A study from the International Journal of Molecular Sciences (2021) confirms that zinc deficiency leads to reduced T cell function and thus can increase the risk of infections.
Zinc and Macrophages
Macrophages, also called "phagocytes," are white blood cells that play an important role in fighting pathogens. They remove germs and foreign substances from the body and produce antibodies to protect the organism. To perform these tasks optimally, macrophages need zinc. This trace element supports the production of signaling molecules necessary for the activation and function of macrophages. A zinc deficiency can cause these cells to not perform their tasks effectively, weakening the body's immune response.
Zinc gluconate: effective against infections
Zinc gluconate has proven to be extremely effective in the treatment and prevention of infections. A 2017 study examined the effect of zinc gluconate in the form of lozenges on cold symptoms. The result was clear: sucking on zinc tablets significantly shortened the duration of cold symptoms such as runny nose, cough, sore throat, and muscle pain. People who regularly took zinc gluconate reported faster recovery and a reduction in symptom severity.
Furthermore, it has been found that people who expose themselves to physical exertion in cold weather – such as winter sports athletes – can significantly reduce their risk of catching a cold by taking about 200 mg of zinc daily. This amount helps strengthen the immune system and prevent infections.
Practical Application
To benefit from zinc gluconate, it is recommended to take zinc supplements especially during cold seasons or periods of increased physical exertion. Zinc lozenges or capsules can help shorten the duration of colds and relieve symptoms. For optimal effect, zinc intake should be maintained over a longer period, with the recommended daily dose adjusted according to needs and health status.
Zinc and vitamin C: a strong team
The combination of zinc and vitamin C is particularly effective when it comes to strengthening the immune system and fighting infections. Both nutrients have strong antioxidant effects, meaning they help the body neutralize harmful free radicals and reduce oxidative stress. This oxidative stress can damage cells and weaken the immune system, making the body more susceptible to illnesses. Through the synergistic effect of zinc and vitamin C, the body is effectively supported in defending itself against these harmful influences.
How the combination works
Zinc promotes the production and activity of immune cells, while vitamin C protects the cells from oxidative damage and supports tissue regeneration. This combination is especially useful for strengthening the immune system, preventing colds, or alleviating their symptoms. Studies have shown that taking both nutrients together can reduce the duration and severity of cold symptoms.
Practical Application
The combination of zinc and vitamin C is especially helpful during times of increased risk of infection, such as during the cold season or under stress. Those who want to effectively strengthen their immune system can take zinc and vitamin C supplements or rely on foods that contain both nutrients, such as citrus fruits, bell peppers, nuts, and legumes.
Our Hormones and Zinc Gluconate
Zinc plays a central role in the body's hormone balance and is involved in numerous important processes. It is essential for the synthesis, storage, and release of insulin, a hormone crucial for regulating blood sugar levels. Without sufficient zinc, the body cannot effectively produce insulin, which can lead to problems such as insulin resistance.
Zinc is also necessary for the metabolism of thyroid hormones and growth hormones, which are responsible for growth, development, and metabolic regulation. A zinc deficiency can lead to thyroid dysfunction and thus impair the entire metabolism.
Another important aspect is zinc's role in regulating testosterone levels. Testosterone is not only important for sexual health and fertility but also influences muscle building and energy levels. Zinc gluconate can help stabilize testosterone levels and thus support physical performance.
Zinc is also important for a healthy acid-base metabolism, as it is involved in regulating the body's pH balance. A balanced acid-base balance is crucial for overall health and well-being.
Zinc Intake Through Food
It is always best to get zinc through a balanced diet. A varied mixed diet that includes both animal and plant sources provides a good foundation. A cyclic ketogenic diet can also contribute to zinc supply if properly planned.
Zinc-Rich Foods
The best natural sources of zinc include animal products such as meat, fish, seafood, especially oysters, as well as dairy products and eggs. Plant sources like legumes, nuts, seeds, and whole grains also contain zinc, but in smaller amounts and often with lower bioavailability.
Challenges in Zinc Absorption
However, there are several factors that can make zinc absorption from food more difficult:
-
Phytic acid
Phytic acid, found in whole grains, legumes, and oilseeds, can significantly inhibit zinc absorption. This substance binds to zinc and prevents it from being properly absorbed by the body. Although these foods are healthy due to their fiber and nutrients, one should be aware that they can impair the utilization of zinc from plant sources. -
Misleading nutritional information
Even though certain foods like walnuts or oats have a high zinc content, the high calorie content of 100 g of these foods often means we have to consume more calories to reach an adequate zinc amount. For example, 100 g of walnuts contain about 2.7 mg of zinc, but this portion also brings 650 kcal. -
Limited bioavailability
Zinc from animal sources is better absorbed by the body than from plant sources. About 40% of zinc is absorbed from animal products like meat, while plant foods often make only about 15% of the contained zinc available. This means that people who eat plant-based diets need to consume larger amounts of zinc-rich foods to meet their needs.
Zinc deficiency: causes and risks
Zinc deficiency can have various causes and is often harder to avoid than it seems at first glance. Even with a balanced diet, there can be situations where zinc requirements are particularly high or zinc absorption is impaired.
Risk groups for zinc deficiency
There are several risk groups in which the likelihood of zinc deficiency is increased:
-
From 65 years old
With increasing age, the body produces less stomach acid, which makes nutrient absorption from food more difficult. This affects not only zinc but also other important minerals and vitamins. Even with a balanced diet, zinc deficiency can occur here. -
Pregnancy and breastfeeding
During pregnancy and breastfeeding, the zinc requirement increases significantly. Especially in the second and third trimesters, there can be an increased need because zinc is also required for fetal development and milk production. Pregnant women are recommended to consume between 11 and 14 mg of zinc daily to meet this need. -
Vegetarian or vegan diet
People who follow a vegetarian or vegan diet have an increased risk of zinc deficiency because plant-based foods usually contain only small amounts of zinc. Additionally, phytates like phytic acid in plant foods bind zinc and prevent its absorption. Vegans and vegetarians should therefore pay special attention to a balanced diet and, if necessary, use zinc supplements. -
Athletes
Regular exercise leads to increased zinc excretion through sweat. Those who train intensively should ensure adequate zinc intake, as this mineral is important for regeneration and the immune system. -
Diabetes
People with diabetes, especially type 2 diabetes, often have a higher zinc requirement because they excrete more zinc through urine (hyperzincuria). Regular monitoring of zinc levels and adjusted zinc intake are therefore particularly important.
Factors that hinder zinc absorption
Besides risk groups, there are also various factors that can negatively affect zinc absorption:
-
Stress
Physical or emotional stress can increase oxidative stress in the body, which in turn increases zinc requirements. Zinc plays an important role in combating free radicals that arise during stress. -
Coffee and tea
The tannins contained in coffee, black and green tea can inhibit zinc absorption. Those who regularly consume large amounts of these beverages should ensure to increase their zinc intake. -
Alcohol and nicotine
Alcohol and nicotine are considered so-called “zinc robbers” because they increase zinc requirements and can impair zinc absorption in the body. People who regularly drink alcohol or smoke should pay extra attention to their zinc intake.
Solutions for preventing zinc deficiency
- A balanced diet with zinc-rich foods such as meat, fish, nuts, seeds, and legumes is the best way to prevent zinc deficiency.
- In certain risk groups, such as pregnant women or athletes, targeted zinc supplementation can be useful.
- However, the intake of zinc supplements should always be done in consultation with a doctor or nutritionist to avoid overdosing.
Zinc gluconate: Your solution for zinc deficiency
In the cases already mentioned, where insufficient zinc intake from food is possible, taking a zinc supplement can be a sensible solution. Zinc gluconate from Euro Nutrador offers a practical way to meet zinc requirements. Each capsule contains 15 mg of the essential trace element and can be easily taken with a meal.
Thanks to the special formulation as zinc gluconate, the preparation is particularly bioavailable, which means that zinc is efficiently absorbed into the body. This not only supports the immune system but also contributes to cell protection as a strong antioxidant.
Practical tips for intake
-
Dosage: The recommended dosage of zinc gluconate is one capsule per day, taken with a meal. This ensures optimal absorption and minimizes possible stomach discomfort.
-
Integrate into the daily routine: It is recommended to take zinc gluconate at a fixed time of day – for example, in the morning with breakfast or in the evening with dinner. This makes it easier to maintain regular intake.
If you are unsure whether zinc gluconate is suitable for your needs, or if you are taking other dietary supplements at the same time, you should discuss this with a doctor or nutritionist.
