Why supplement?
Marked asPrimarySupporting
Supports immune-cell function
Zinc maintains neutrophil and natural-killer-cell activity and also stabilizes skin and intestinal mucosa. Oysters, red meat, and organ meats are high in it; the body has no large zinc store, so faded taste and repeated mucosal breaks often appear first in people whose intake is short.
Promotes wound and tissue repair
Collagen synthesis, nucleic-acid replication, and cell proliferation all need zinc-dependent enzymes; cell turnover at the wound edge especially uses them. In adolescents growing, after surgery, or with repeated broken skin, what is felt sits in how fast the wound closes and whether new tissue is firm.
Maintains taste and smell
Taste buds and olfactory receptors turn over continuously; when zinc is short, flavor fades and food becomes dull. Phytate in whole grains and legumes lowers availability; zinc from oysters and red meat is more readily transported in the gut. People whose taste has faded often map the gap here first.
Which symptoms may ease?
Frequent colds
Zinc maintains neutrophil and natural-killer-cell activity and also stabilizes skin and intestinal mucosa. Oysters, red meat, and organ meats are high in it; the body has no large zinc store, so faded taste and repeated mucosal breaks often appear first in people whose intake is short. People whose throats itch in cold air and who catch colds often more often notice fewer unwell days after several continuous weeks.
Slow wound healing
Collagen synthesis, nucleic-acid replication, and cell proliferation all need zinc-dependent enzymes; cell turnover at the wound edge especially uses them. In adolescents growing, after surgery, or with repeated broken skin, what is felt sits in how fast the wound closes and whether new tissue is firm. People whose small cuts crust slowly and keep splitting more often notice healing speed and a smoother scar surface after several continuous weeks.
Acne spots
Zinc maintains neutrophil and natural-killer-cell activity and also stabilizes skin and intestinal mucosa. Oysters, red meat, and organ meats are high in it; the body has no large zinc store, so faded taste and repeated mucosal breaks often appear first in people whose intake is short. People with recurring red spots on the chin or cheeks more often notice fewer new lesions and smoother skin after several continuous weeks.
Hair loss
Zinc maintains neutrophil and natural-killer-cell activity and also stabilizes skin and intestinal mucosa. Oysters, red meat, and organ meats are high in it; the body has no large zinc store, so faded taste and repeated mucosal breaks often appear first in people whose intake is short. People who shed more when combing and whose crown looks thinner more often notice shed amount and hair density after several continuous weeks.
Which conditions may it support?
Common cold
Zinc maintains neutrophil and natural-killer-cell activity and also stabilizes skin and intestinal mucosa. Oysters, red meat, and organ meats are high in it; the body has no large zinc store, so faded taste and repeated mucosal breaks often appear first in people whose intake is short. People who congest and get a sore throat when seasons change more often notice cold frequency and how long each spell lasts after several continuous weeks.
Age-related macular degeneration
Zinc maintains neutrophil and natural-killer-cell activity and also stabilizes skin and intestinal mucosa. Oysters, red meat, and organ meats are high in it; the body has no large zinc store, so faded taste and repeated mucosal breaks often appear first in people whose intake is short. People watching central vision and contrast more often notice reading clarity and exam markers after several continuous weeks.
Acne vulgaris
Zinc maintains neutrophil and natural-killer-cell activity and also stabilizes skin and intestinal mucosa. Oysters, red meat, and organ meats are high in it; the body has no large zinc store, so faded taste and repeated mucosal breaks often appear first in people whose intake is short. People with recurring inflamed papules more often notice fewer new lesions and less redness after several continuous weeks.
Male infertility
Zinc maintains neutrophil and natural-killer-cell activity and also stabilizes skin and intestinal mucosa. Oysters, red meat, and organ meats are high in it; the body has no large zinc store, so faded taste and repeated mucosal breaks often appear first in people whose intake is short. People watching semen-analysis numbers more often notice follow-up reports after several continuous weeks.
How to take it?
