Zinc Benefits for Men's Health and Sex | Zinc Deficiency, Dosage

Zinc is considered an essential nutrient, meaning that your body can’t produce or store it. Zinc is needed for the proper growth and maintenance of the human body. It is found in several systems and biological reactions, and it is needed for immune function, wound healing, blood clotting, thyroid function, and much more. Meats, seafood, dairy products, nuts, legumes, and whole grains offer relatively high levels of zinc.

Zinc deficiency is not uncommon worldwide. Symptoms include slowed growth, low insulin levels, loss of appetite, irritability, generalized hair loss, rough and dry skin, slow wound healing, poor sense of taste and smell, diarrhea, and nausea. Moderate zinc deficiency is associated with disorders of the intestine which interfere with food absorption (malabsorption syndromes), alcoholism, chronic kidney failure, and chronic debilitating diseases.

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

Zinc might also have effects against viruses. It appears to lessen symptoms of the rhinovirus (common cold), but researchers can’t yet explain exactly how this works. In addition, there is some evidence that zinc has some antiviral activity against the herpes virus.

Low zinc levels can be associated with male infertility, sickle cell disease, HIV, major depression, and type 2 diabetes, and can be fought by taking a zinc supplement.

Health Benefits of Zinc for Men

  • May Improve Immune Function
  • May Promote Blood Sugar Control

[ Try: Moderate Capsules to Control Blood Sugar Levels After Meals ]

  • Helps Fight Acne
  • May Improve Heart Health
  • Slows Macular Degeneration
  • Benefits of Zinc for Men Sexually: Zinc is one of the essential trace elements and its supplementation was found to increase semen volume, sperm motility, and sperm quality in men.

    Highlights of Zinc for Human Body

    Let’s see some of the highlights of Zinc!

    • Zinc is necessary for the activity of over 300 enzymes that aid in metabolism, digestion, nerve function, and many other processes.
    • Zinc supplementation was found to significantly increase the semen volume, sperm motility, and the percentage of normal sperm morphology.
    • This mineral is also fundamental to skin health, DNA synthesis, and protein production.
    • Zinc supplements significantly reduce the risk of infections and promote an immune response in older adults.
    • Zinc may relieve oxidative stress and improve immune response by boosting the activity of T-cells and natural killer cells, which help protect your body from infection.

      Zinc Deficiency Symptoms

      Symptoms of severe zinc deficiency include impaired growth and development, delayed sexual maturity, skin rashes, chronic diarrhea, impaired wound healing and behavioral issues.

      It is estimated that around 2 billion people worldwide are deficient in zinc due to inadequate dietary intake.

      Since zinc deficiency impairs your immune system – increasing the chances of infection – zinc deficiency is thought to cause over 450,000 deaths in children under 5 every year.

      Those at risk of zinc deficiency include:

      • People with gastrointestinal diseases like Crohn’s disease
      • Vegetarians and vegans
      • Pregnant and breastfeeding women
      • Older infants who are exclusively breastfed
      • People with sickle cell anemia
      • People who are malnourished, including those with anorexia or bulimia
      • People with chronic kidney disease
      • Those who abuse alcohol

      Symptoms of mild zinc deficiency include diarrhea, decreased immunity, thinning hair, decreased appetite, mood disturbances, dry skin, fertility issues, and impaired wound healing.

      Best Natural Foods to Increase Zinc Levels in the Body

      Many animal and plant foods are naturally rich in zinc, making it easy for most people to consume adequate amounts.

      Foods highest in zinc include:

      • Shellfish: Oysters, crab, mussels, lobster and clams
      • Meat: Beef, pork, lamb and bison
      • Poultry: Turkey and chicken
      • Fish: Flounder, sardines, salmon and sole
      • Legumes: Chickpeas, lentils, black beans, kidney beans, etc.
      • Nuts and Seeds: Pumpkin seeds, cashews, hemp seeds, etc.
      • Dairy Products: Milk, yogurt and cheese
      • Eggs
      • Whole Grains: Oats, quinoa, brown rice, etc.
      • Certain Vegetables: Mushrooms, kale, peas, asparagus and beet greens

      Animal products, such as meat and shellfish, contain high amounts of zinc in a form that your body easily absorbs.

      Keep in mind that zinc found in plant-based sources like legumes and whole grains is absorbed less efficiently because of other plant compounds that inhibit absorption.

      Are There Any Side Effects with Zinc?

      Zinc is likely safe for most adults when taken by mouth in amounts not larger than 40 mg daily. Routine zinc supplementation is not recommended without the advice of a healthcare professional. In some people, zinc might cause nausea, vomiting, diarrhea, metallic taste, kidney and stomach damage, and other side effects.

      Zinc is possibly safe when taken by mouth in doses greater than 40 mg daily, especially when these doses are taken only for a short period of time. There is some concern that taking doses higher than 40 mg daily might decrease how much copper the body absorbs. Decreased copper absorption may cause anemia.

      Taking high amounts of zinc is likely unsafe. High doses above the recommended amounts might cause fever, coughing, stomach pain, fatigue, and many other problems. Taking more than 100 mg of supplemental zinc daily or taking supplemental zinc for 10 or more years doubles the risk of developing prostate cancer. There is also concern that taking large amounts of a multivitamin plus a separate zinc supplement increases the chance of dying from prostate cancer. Taking 450 mg or more of zinc daily can cause problems with blood iron. Single doses of 10-30 grams of zinc can be fatal.

      Does Zinc Interact with Other Drugs?

      Moderate Interaction

      • Antibiotics (Quinolone antibiotics)
      • Antibiotics (Tetracycline antibiotics)
      • Cisplatin (Platinol-AQ)
      • Penicillamine

      Minor Interaction

      • Amiloride (Midamor)

      Dosages of Zinc that Have Been Studied

      • General: Recommended Dietary Allowance (RDA) quantities of zinc have been established for boys and men age 14 and older, 12 mg/day; women 19 and older, 8 mg/day; pregnant women 14 to 18, 10-12 mg/day; pregnant women 19 and older, 11 mg/day;
