zinc

The underestimated trace element for testosterone, immune system & fertility

Zinc is an essential trace element that the body cannot produce itself. It is involved in over 300 enzymatic processes, including testosterone production , spermatogenesis , wound healing , cell division , the immune system , and detoxification . Zinc plays a particularly important role for men: it influences fertility , skin health , muscle growth , stress resistance , and protection against oxidative stress.

What does zinc do in the body?

  • Supports testosterone production (inhibits aromatase, stimulates LH release)
  • Spermogenesis : improves sperm count, motility, and morphology
  • Boosts the immune system (antiviral & anti-inflammatory)
  • Improves wound healing and regeneration
  • Protects against oxidative stress (antioxidant)
  • Affects insulin sensitivity and blood sugar regulation

Symptoms of zinc deficiency

  • Loss of libido
  • Fatigue, depressive moods
  • Poor wound healing, frequent infections
  • Skin problems, brittle nails, hair loss
  • Concentration problems
  • Reduced sperm quality
  • Gynecomastia or symptoms of estrogen dominance

Men with chronic stress, intense physical exertion, a vegetarian diet, or intestinal diseases are particularly at risk.

Causes of zinc deficiency

  • Malnutrition / unbalanced diet
  • Vegetarian or vegan diet (zinc from plants is less bioavailable)
  • Chronic alcohol or caffeine consumption
  • Sports (zinc loss through sweat)
  • Intestinal diseases (e.g., irritable bowel syndrome, leaky gut)
  • Chronic stress (cortisol inhibits zinc absorption)

Good sources of zinc

  • Beef and lamb
  • Oysters (highest salary)
  • Eggs, cheese, Brazil nuts
  • Pumpkin and sunflower seeds
  • Oat flakes, lentils (limited absorption due to phytates)

Laboratory values

  • Zinc in serum: 70-120 µg/dl
  • Functional markers: Alkaline phosphatase , urinary zinc excretion
  • Ideal in combination with: copper, ferritin, vitamin D, testosterone

Conclusion

Zinc is a key mineral for men's health. It supports hormonal balance, fertility, the immune system, and metabolic processes. Adequate zinc levels help stabilize testosterone, protect the body from oxidative stress, and maintain male vitality in the long term.

Mental Load

Mental load refers to the persistent mental strain caused by the invisible thinking and organizational work of everyday life. In men, chronic mental load can also lead to exhaustion, irritability, sleep problems, and difficulty concentrating. In the long term, this constant mental strain can be associated with hormonal imbalances, elevated cortisol levels, and reduced testosterone production. Consciously reducing stress and prioritizing tasks is essential for mental health and stress prevention.

Sexual health

Sexual health describes physical, emotional, and social well-being in relation to sexuality. It encompasses aspects such as libido, erectile function, hormonal balance, fertility, and a fulfilling and self-determined sexuality. In men, not only testosterone levels and vascular health play a role, but also psychological factors, relationship dynamics, and lifestyle. Sexual health problems can be early indicators of hormonal or metabolic disorders and should be taken seriously and investigated individually.

Urological check-up

A urological check-up is a preventative examination for the early detection of urological diseases such as an enlarged prostate, prostate cancer, urinary tract infections, or hormonal imbalances. The examination typically includes a physical examination, urinalysis, PSA testing, and, if necessary, an ultrasound. Men are advised to have a urological check-up annually starting at age 45. Even younger men with symptoms such as loss of libido, erectile dysfunction, or a family history of urological issues may benefit from an early check-up.
