A mineral worth knowing.Oysters are a dietary zinc source. Mangosteen measurements tell a different research story.

Zinc helps enzymes work, supports cell division and contributes to normal immune function. We explore those roles, food sources and research measuring zinc directly in mangosteen pericarp.

ZnZinc
An essential trace mineral.

01 · Begin with the essentials

Why the Body Needs Zinc

Zinc is a trace mineral used by hundreds of enzymes. The body also needs it to make DNA and proteins, divide cells and support normal immune function and wound healing.(1)

02 · Versatility at the cellular level

How Zinc Helps Cells Work

Enzymes and proteins.

Zinc helps enzymes carry out chemical reactions. It also helps some proteins keep the shape they need to function.(1)

DNA and cell division.

Making a new cell requires genetic material and proteins. Zinc participates in the reactions that produce them and allow cells to divide.(1)

Nutrition in focus

Zinc Status and Supplement Research

Too little zinc can affect appetite, immune function and wound healing. These consequences show why an adequate supply matters for maintaining tissues and defenses.(1)

Some trials of oral zinc lozenges started early in a cold have found a shorter illness. That evidence is specific to the preparations and amounts tested; it cannot be assumed for any food or supplement that contains zinc.(1)

Taking high doses for a long time can reduce copper absorption. Zinc’s relationship with copper is one reason appropriate intake matters more than simply taking extra.(1)

Why Zinc Deficiency Can Affect the Senses

A significant zinc deficiency can alter taste and smell. These senses rely on specialized cells and proteins whose normal function depends on adequate nutrition.(1)

Which foods provide zinc?

04 · Zinc across the diet

Familiar Foods.
Different Dietary Sources.

Seafood and several plant foods contain zinc. The amount absorbed differs across foods and diets.(1)

Phytates in plant foods can reduce zinc absorption. Food zinc content and the amount absorbed are different questions.(1)

Plants also need zinc for growth and normal enzyme activity.

The Living Plant
Needs Zinc, Too.

Plants need zinc as a micronutrient for normal growth and the activity of many enzymes and proteins.(3)

General plant biology helps explain the mineral’s place in a living tree.

Researchers have measured zinc directly in mangosteen pericarp.

06 · Pericarp research

2.9mg per 100 g dry matterZinc measured in mangosteen pericarp: 2.9 ± 0.2 mg per 100 g dry matter.(2)

A closer look at the pericarp

Zinc Measured in Mangosteen Pericarp

A 2026 study by Wilcaso and colleagues analyzed mangosteen leaves, pericarp, seeds and pulp separately. The pericarp contained 2.9 ± 0.2 milligrams of zinc per 100 grams of dry matter.(2)

Pericarp analyzed separately

The measurement comes from the outer pericarp, analyzed separately from the pulp.

Dry-matter basis

The result is expressed per 100 grams of dry matter.
