Sodium, potassium, and chloride regulate water balance in your body.
Electrolytes split into charged ions in water, which helps keep fluid balance.
The movement of these minerals across cell walls controls where water goes in your body.

If you do not get enough of these minerals, your body can lose too much water or hold on to too much, which can affect your health and blood pressure.

Boosting Immunity and Healing

The role of minerals in your body also includes protecting you from illness and helping you heal. Zinc and copper are important for your immune system and for repairing wounds. Iron helps your blood carry oxygen to tissues that need to heal. These minerals support the production of hormones and enzymes that fight infection and help your body recover.

Mineral	Role in Immune System and Wound Healing
Zinc	Regulates enzymes involved in tissue repair, growth, and immune function; acts as an antioxidant; essential for collagen, DNA, RNA, and protein synthesis, and cellular proliferation. Deficiency linked to chronic wounds.
Copper	Modulates cytokines and growth factors during all stages of wound healing; low intake can be improved with supplementation.

You need enough minerals to keep your immune system strong and to heal quickly from injuries. The role of minerals in blood health is also important, as iron helps make haemoglobin, which carries oxygen to your cells.

Tip: Eating a variety of foods helps you get all the minerals you need for strong bones, healthy teeth, muscle movement, hydration, and a strong immune system.

The role of minerals in your body covers many areas. They build and protect your bones and teeth, help your muscles and nerves work, keep your body hydrated, and support your health every day.

Function of Minerals in Daily Processes

Enzyme Activation and Metabolism

You depend on minerals every day to keep your body running smoothly. One important function of minerals is to help enzymes work. Enzymes are special proteins that speed up chemical reactions in your body. Without the right minerals, these enzymes cannot do their jobs. You need minerals to help build strong bones and teeth, keep your blood sugar steady, and balance fluids in your body. Some minerals, like zinc, can change between different forms. This ability helps them take part in many reactions.

Minerals act as helpers, or cofactors, for hundreds of enzymes. For example, zinc supports over 300 enzymes. These enzymes help with bone health, protect your cells, and keep your metabolism working. When you get enough minerals, your cells and tissues stay healthy.

Minerals act as cofactors for enzymes and metabolic reactions.

Mineral Absorption and Balance

How the Body Absorbs Minerals

Your body absorbs minerals mainly in the small intestine. When you eat food or take supplements, minerals break down and move through your digestive system. Probiotics, which are helpful bacteria in your gut, can boost the absorption of important minerals like calcium, zinc, and magnesium. A healthy gut helps you get more minerals from your meals. Each person has a unique mix of gut bacteria, so mineral absorption can be different for everyone. If you keep your gut healthy, you can improve how well your body takes in minerals and supports your overall health.

Factors Affecting Mineral Uptake

Intestinal bacteria significantly influence the bioavailability of minerals. For instance, the presence of Lactobacillus spp. in cheese enhances the bioavailability of magnesium (Mg) by approximately 18%. Additionally, fermented products like goats’ milk with Lactobacillus plantarum also improve Mg absorption. Furthermore, fermentation processes in soy milk reduce phytic acid content, which in turn increases the bioavailability of Mg and other minerals.

Many things can change how well you absorb minerals. The type of food you eat matters. Fermented foods, like yogurt and cheese, often help your body take in more minerals. Cooking methods and the presence of other nutrients can also make a difference. If you eat a lot of fiber or foods with phytic acid, your body may not absorb as many minerals. Eating a variety of foods and including some fermented products can help you get the minerals you need.

Storage and Regulation

Your body keeps minerals in balance by controlling how much you absorb, store, and remove. For example, you absorb iron in your intestines using special transporters. Your kidneys help control minerals like selenium and iodine by removing extra amounts through urine. This careful system stops you from having too little or too much of any mineral. It helps you stay healthy and keeps your body working well every day.

Tip: Drink enough water and eat a balanced diet to support mineral absorption and balance.
