In the realm of essential minerals, zinc often operates in the shadows, overshadowed by more prominent counterparts like iron and magnesium. Yet, zinc silently plays a crucial role in fortifying the immune system and is instrumental in the formation and upkeep of collagen—a protein vital for the support of skin, bones, and tissues.
Pharmacist Meritxell Martí sheds light on the significance of zinc, emphasizing that although the body requires only minute amounts of this trace element, its involvement in various metabolic cycles is pivotal.
Functions of Zinc:
Immune System Support:
Facilitates the formation of leukocytes, lymphocytes, and neutrophils.
Regulates cytokine production, influencing the immune system's response.
Mucosal Barrier Integrity:
Maintains mucosal barriers, including those in the gastrointestinal tract.
Collagen Formation:
Indispensable for the transformation of proline into hydroxyproline, crucial for collagen structure.
Vital for connective tissue formation.
Skin Repair:
Essential for wound and incision healing.
Contributes to protein synthesis and cell regeneration.
Sebum Regulation:
Regulates sebum secretion, balancing hormonal activity.
Influences sex hormone regulation, including testosterone.
Anti-Inflammatory Action:
Aids in reducing pore size and improving skin texture.
Hormonal and Reproductive System:
Impacts reproductive function, sperm production, and DNA synthesis.
Essential for normal development and growth in childhood and adolescence.
Cellular Protection and Antioxidant:
Protects cells from oxidative damage and regulates cell death.
Eye Health:
Concentrated in the retina, contributing to eye health.
Taste and Olfactory Receptors:
Vital for taste and olfactory receptors.
While scientific evidence is evolving, some suggest that combining injectables like botulinum toxins with magnesium may prolong the effects.
Natural Dietary Sources of Zinc:
Zinc-rich foods include beef, lamb, pork, oysters, tuna, sardines, salmon, chicken, turkey, eggs, dairy products, legumes, nuts, whole grains, pumpkin seeds, hemp seeds, and sunflower seeds.
Detecting Zinc Deficiency:
Zinc deficiency manifests in weakened immunity, increased vulnerability to infections, delayed development in children, skin issues (dermatitis, eczema, acne), hindered wound healing, fatigue, weakness, taste and smell changes, and loss of appetite.
Zinc Supplements:
Supplements can help prevent deficiencies and offer benefits such as immune support, collagen preservation, and anti-inflammatory effects. Dosages vary, and consultation with healthcare professionals is advisable.
Safe Consumption and Potential Risks:
Quality assurance is crucial when opting for supplements. Adults generally require 8 to 11 mg/day, with higher doses under medical supervision. Individuals with kidney diseases, absorption issues, allergies to zinc, or certain medications may need caution. Excessive intake may lead to gastrointestinal problems and disrupt the balance of essential minerals, emphasizing the delicate equilibrium in the body.
