Trace minerals

Trace Minerals are a group of minerals that are required by the human body in minute amounts, typically less than 100 milligrams per day. Despite their small required quantity, they play a crucial role in maintaining optimal health.

Overview

Trace minerals, also known as microminerals, include iron, zinc, copper, selenium, manganese, fluoride, chromium, molybdenum, iodine, and others. These minerals are essential for a variety of biological functions, including immune system support, bone health, and metabolism regulation.

Functions

Each trace mineral has a unique role in the body. For example, iron is necessary for oxygen transport in the blood, while zinc is involved in enzyme activity and immune function. Copper aids in energy production and iron metabolism, and selenium acts as an antioxidant to protect cells from damage.

Sources

Trace minerals are found in a variety of foods. Iron can be obtained from meat, poultry, and fish, while zinc is abundant in oysters, beef, and crab. Copper is found in organ meats, shellfish, and nuts, and selenium is present in Brazil nuts, tuna, and halibut.

Deficiency and Toxicity

Both deficiency and excess of trace minerals can lead to health problems. For instance, iron deficiency can cause anemia, while excess iron can lead to hemochromatosis. Similarly, zinc deficiency can result in growth retardation and impaired immune function, while excess zinc can interfere with copper absorption and cause nausea and vomiting.
