Zinc is an important trace element for the proper functioning of the body. Zinc is involved in the synthesis of enzymes and hormones, supports both the female and male reproductive systems, is an essential component of hair and nails, and strengthens the immune system.

How to choose the right zinc-containing preparations?

When choosing zinc supplements, it is important to consider its compatibility with other dietary supplements. It should be remembered that some drugs may interfere with the absorption of others.

So the bioavailability of zinc, reducing it, is affected by: iron, folic acid, calcium, magnesium. Therefore, it is recommended to take these minerals at different time intervals with an interval of at least two hours.

Given the variety of forms presented on the market, I propose to analyze the most popular offers.

Symptoms of zinc deficiency

You can notice a zinc deficiency by the fact that the skin and mucous membranes become dry and cracks appear on them. Hair loses its shine and falls out, nails peel and break. Later, problems begin with the digestive tract (disorders arise, for example).

Among the main symptoms of zinc deficiency are:

  • insomnia and problems falling asleep;
  • poor appetite;
  • hair loss and brittle nails;
  • irritability;
  • drop in insulin levels;
  • wounds heal poorly;
  • poor skin condition;

If the zinc deficiency is small, this problem does not manifest itself in the early stages. If there is a slight lack of a microelement or if it is normal, and a person takes medications with zinc in large dosages for a long time, intoxication of the body is possible. Therefore, it is very important to know for sure whether there is a deficiency, and to take a course of vitamins only after consulting a doctor.


Signs of zinc deficiency

How to choose a zinc supplement

Vitamins with zinc must be chosen like any other drug: focus on certain criteria. These include possible allergic reactions, the age of the patient (the form of release depends on this), and how obvious the signs of zinc deficiency are, it is important to study contraindications and side effects. So, in more detail:

  1. Allergic reactions.
    Medicines and vitamin complexes often contain dyes, preservatives and flavors. Intolerance can be to both the main active ingredient and auxiliary components. If you are prone to allergies, be sure to consult your doctor before taking zinc.
  2. Drug interactions.
    It happens that taking several specific medications is undesirable. Zinc, for example, is better not to combine with manganese, calcium, magnesium, tin, iron, copper and folic acid. Doctors recommend taking zinc only 2 hours after foods rich in these substances. Taking zinc reduces the absorption of certain antibiotics.
  3. Age.
    When choosing a form of release of a zinc preparation, it is necessary to take into account the age of the patient. For children, it is better to buy zinc in the form of water-soluble effervescent tablets.
  4. Level of zinc deficiency.
    If a person has a mild form of zinc deficiency (this does not affect his performance), you can simply adjust your diet and not buy a zinc supplement.

Zinc. What is it good for and how much does the body need?

Articles

Zinc is not such a popular trace element as iron, calcium or magnesium, but the functioning of our body without it will definitely not be harmonious and healthy! It is one of the 16 essential minerals we need to live and feel fulfilled. However, Zn is considered a trace element, which means we need small amounts of it. Even in microdoses, it plays a mega-important role in skin health, maintaining immunity and many other processes in the body.

How much zinc does the body need?

This microelement does not accumulate in the body, so it is important to receive it daily - with food or vitamin supplements. Fortunately, you only need a small amount—8 mg per day for women and 11 mg per day for men.

If you eat a healthy diet, eating a variety of fresh foods, animal protein and dairy, and plant-based foods such as cashews, pumpkin seeds, chickpeas and oatmeal, you get zinc from your diet. But there's a caveat: "Plant-based foods such as grains, legumes, nuts, and seeds contain phytates, which can bind to zinc and make it less absorbable," writes nutritionist Jackson Blatner.

If you are a vegetarian, eat little fresh plant foods, or eat irregularly, then take a multivitamin containing zinc. This will help you maintain its balance in the body.

Zinc-rich foods

It is important to remember that these products must be fresh, environmentally friendly, then the body will really benefit from them.

Note that many zinc products also contain another metal called cadmium. This is because zinc and cadmium are chemically similar and often occur together in nature. Exposure to high levels of cadmium over a long period of time can lead to kidney failure. What to do? Look for zinc gluconate products or take a zinc vitamin supplement. Zinc gluconate consistently contains the lowest levels of cadmium.

What are the benefits of zinc?

Zn is taken orally to treat and prevent zinc deficiency and its consequences, including growth retardation and acute diarrhea, slow wound healing, and decreased immunity. Zinc preparations are also used:

  • to strengthen the immune system, improve the health of children and adults
  • for the treatment of colds, flu, upper respiratory tract infections, prevention and treatment of lower respiratory tract infections
  • for eye diseases, night blindness and cataracts.
  • for nervous disorders, depression after pregnancy (postpartum depression)
  • for problems with fertility in men and enlarged prostate glands, as well as for erectile dysfunction (ED).
  • for osteoporosis, rheumatoid arthritis, psoriatic arthritis
  • for the treatment of hair loss, psoriasis, eczema, acne and other skin diseases

Some athletes use zinc internally to improve athletic performance, endurance, and strength.

How to determine zinc deficiency

Zinc deficiency is not uncommon throughout the world. Its symptoms include slow growth, low insulin levels, loss of appetite, irritability, severe hair loss, rough and dry skin, slow wound healing, poor sense of taste and smell, diarrhea and nausea.

Moderate Zn deficiency is associated with intestinal diseases that interfere with food absorption, chronic kidney failure, and chronic debilitating diseases.

Zinc plays a key role in maintaining vision. Zinc deficiency can alter vision, and severe deficiency can cause changes in the retina (the back of the eye where the image is focused).

Low zinc levels may be associated with male infertility, sickle cell disease, HIV, major depression and type 2 diabetes, and can be combatted by taking zinc supplements.

The 5 Most Important Effects of Zinc

  1. Zinc strengthens the immune system. First, Zn is critical for normal immune cell development, so it's important to get enough of the mineral at all times. Zinc supplements can be used during times of illness to reduce the duration and severity of a cold.
  2. Zinc can help heal skin, including acne and pimples . Research shows that people with acne have lower levels of this trace mineral in their blood and skin. It also plays a key role in wound healing—in fact, it is involved in every stage of the process, from blood clotting and inflammation to tissue renewal and scar formation. So if you find that cuts, scrapes and burns are taking a long time to heal, start taking zinc supplements!
  3. Zinc will help maintain your vision as you age. Several studies have found that taking zinc supplements may help protect against advanced age-related macular degeneration. This is a condition that can lead to vision loss and is most common in people over 50 years of age.
  4. Zinc helps with eating disorders (anorexia nervosa). Regular oral zinc supplementation may help increase weight gain and improve symptoms of depression in adolescents and adults.
  5. Zinc will strengthen weak and brittle bones (prevents osteoporosis). Low Zn intake is associated with lower bone mass. Taking a zinc supplement in combination with copper, manganese and calcium may reduce bone loss in women who have gone through menopause.

Dose and side effects when taking zinc

By mouth: Zinc is generally safe for most adults when taken orally in amounts of no more than 40 mg per day. Taking large amounts of Zn is unsafe! High doses higher than recommended may cause fever, cough, abdominal pain, fatigue and many other problems.

Important! Taking more than 100 mg of extra zinc per day or taking extra zinc for 10 years or more doubles the risk of developing prostate cancer. Taking 450 mg or more of zinc per day may cause problems with iron in the blood.

Children and teenagers: Zinc is safe when taken by mouth in the recommended amount.

Pregnancy and breastfeeding: Zinc is generally safe for most pregnant and breastfeeding women when used at recommended daily allowances (RDA). Pregnant women over 18 years of age should not take more than 40 mg of zinc per day; Pregnant women between the ages of 14 and 18 should not take more than 34 mg per day. Breastfeeding women over 18 years of age should not take more than 40 mg per day; lactating women aged 14 to 18 years should not take more than 34 mg per day.

Alcoholism: Long-term excessive alcohol consumption is associated with poor absorption of zinc into the body.

Diabetes: Large doses of Zn may lower blood sugar levels in people with diabetes. People with diabetes should use zinc products with caution.

Vegetarianism: Associated with lower zinc absorption and considered a risk factor for malnutrition.

Combinations with zinc

If you decide to take a zinc supplement, just know that it may interact with certain medications. Thus, Zn should not be taken at the same time as antibiotics, penicillamine or iron supplements - it is better to wait two to three hours between them. It's also worth noting that too much zinc can prevent your body from properly absorbing copper, so keep your dose below 40 mg per day.

Forms of zinc - which one to choose

Almost any manufacturer of dietary supplements has its own line of zinc-containing additives, so you can choose a jar with the optimal price-dosage ratio. But in order not to make a mistake and not always waste money, always pay attention to the composition indicated on the label. The effectiveness of zinc-containing complexes is determined by the form of the active substance.

There are several forms of zinc: oxide, sulfate, glycinate, acetate, picolinate, gluconate, citrate and monomethionine. They differ in purpose, degree of absorption and the presence/absence of side effects.

Zinc oxide and sulfate

- inexpensive forms of zinc, but they have the lowest bioavailability (up to 48%), and when taken orally they can cause heartburn, stomach pain, and nausea. The presence of this form in supplements is undesirable.

Zinc oxide and sulfate are added to cosmetics; they are harmless for external use. Often used as anti-inflammatory and anti-aging components.

Zinc acetate

has good digestibility (up to 60%), but is suitable as an immunostimulating supplement during colds and flu.

Zinc gluconate

- one of the most inexpensive and easily digestible forms (up to 60%), in addition to replenishing the deficiency, this supplement can be used during colds.

Zinc citrate

has a maximum degree of digestibility (up to 61%), is easily accepted by the body and does not cause side effects.

Zinc Picolinate

- the king among supplements, as it combines absolute safety and high bioavailability. The disadvantage of this form is, perhaps, the price - due to complex production, such an additive is much more expensive than its analogues.

Chelated forms (glycinate, monomethionine)

also belong to highly effective (absorbed up to 58%) and safe forms that do not cause side effects and are suitable both for eliminating deficiency and as support for diseases of a viral and bacterial nature.

Knowing about the active forms of zinc, remember not to purchase a supplement where the form is not specified in the description. Perhaps this is an oversight by the manufacturer and there may be a high-quality product in the jar, but you can’t know for sure, which means it’s better to choose those brands that have nothing to “hide”.

At the same time, magnesium is necessary in the processes of nerve impulses and muscle contraction, so its intake is very important during stress and physical activity. Zinc, in turn, promotes healthy bone formation, supports immunity and healthy hair. “Calcium-magnesium-zinc” contains calcium and magnesium in an optimal physiological ratio, which helps normalize the mineral balance in the body.

Vitamin D (Calciferol)

This is a substance that is produced by the adrenal glands after exposure to ultraviolet B rays on the skin. Vitamin D is similar in structure to steroid hormones. It can accumulate in adipose tissue and therefore, before taking products with calciferol, it is necessary to take a blood test for its content in order to avoid an overdose.

There are 6 forms of vitamin D, but most often in food, medicine and vitamin complexes it is found in 2 forms - vitamin D2 and D3.

Preparations and complex products with vitamin D:

  • Vitamin D3;
  • Calcium D3 Nycomed Forte;
  • Calcemin Advance No. 60;
  • Vitamin D2;
  • Aquavit D3;
  • Decrystol D3;
  • Calcium magnesium with vitamin D3.

Vitamin D: the benefits of the “sunshine vitamin”

Vitamin D3 (cholecalciferol) is considered the most effective of all forms of the substance in question. It is involved in the regulation of mineral metabolism, helps normalize blood clotting, and suppresses the growth and formation of cancer cells. Separately, the ability of this vitamin to ensure the growth and development of bone tissue is highlighted. Its deficiency leads to rickets.

Vitamin D3 has a significant effect on the body's immune function. Thus, this substance increases the motor (chemotaxis) and phagocytic function (capture and absorption of pathogens) of immune cells, which leads to a rapid reaction to a foreign body, for example, a virus or bacteria. However, it is important to note that in order for vitamin D to provide benefits, it must be taken in the recommended amount.

Daily value of vitamin D

Each age category is recommended to drink the vitamin in question in the following quantities:

  • children under 1 year - 10 mcg;
  • children from 1 year to 18 years - 15 mcg;
  • adults 19 years and older - 15 mcg.

The maximum permissible dose that does not lead to negative consequences is 100 mcg.

Vitamin D overdose

It should be emphasized once again that the substance in question can accumulate in the body, so if it is taken in large quantities, it can lead to an overdose and have a toxic effect. Vitamin D functions like a steroid hormone. It is involved in signaling between cells, and if consumed excessively, this process can be disrupted.

Due to an overdose, the following reactions occur:

  • constipation and problems with stool;
  • weakness;
  • hypercalcemia (increased levels of calcium in the blood) and kidney stones;
  • renal failure;
  • weight loss;
  • nervous itching;
  • heart rhythm problems;
  • nausea;
  • confusion and vomiting;
  • vomit;
  • stomach ache;
  • feeling tired and dizzy.

Interaction with other substances and drugs

Hormonal drugs . This category of drugs includes contraception, glucocorticosteroids, and drugs for the treatment of the thyroid gland. Taking vitamin D may interfere with your body's ability to absorb these medications.

Anticonvulsant drugs . They increase the breakdown of vitamin D and reduce the rate of absorption of calcium into the blood.

Laxatives . Long-term use of strong laxatives leads to decreased absorption of vitamin D and calcium.

Diuretics . Taking these medications together with vitamin D can lead to hypercalcemia, which provokes urolithiasis in the kidneys.

Take vitamins in recommended dosages and do not combine them with the substances and drugs indicated in the text, so as not to harm your health.

Before you start taking vitamins and minerals, it is best to consult your doctor. Remember, an overdose of vitamins is unsafe!
