Zinc
Here’s what it reflects — and what to do about it.
Longetic pulls together every lab and record you’ve had, follows how Zinc changes over time, and explains what’s shifting — so you walk into your next appointment prepared, with reminders for retests along the way.
What is Zinc?
An essential mineral your body needs for immune function, wound healing, growth, and many enzyme reactions.
Zinc is a mineral involved in immune defense, wound healing, growth, and the activity of many enzymes. Lower levels can be associated with poor intake or absorption and, over time, with issues such as slower wound healing or reduced immune function, though the blood test is an imperfect snapshot of the body's total zinc. Higher levels are usually related to supplement use. Most people in the United States get an adequate amount of zinc, so deficiency is not common here.
What to know about Zinc
Understanding Zinc means knowing what it reflects, what tends to move it, and the signs that suggest it’s worth a closer look — so you can bring the right questions to your next appointment.
