Vitamins and minerals are micronutrients. Unlike carbohydrates, protein, and fats, they do not provide significant amounts of energy, but they are essential for many processes throughout the body.There are 13 essential vitamins and a range of essential minerals that your body needs for normal function. Each nutrient has a different role, and getting a variety of foods can help provide them.

Types of Nutrients

Vitamins and minerals are both micronutrients, but they are different types of substances.

Vitamins

Vitamins are organic compounds found naturally in foods and are needed for various body functions.

Minerals

Minerals are inorganic elements that come from the environment and are obtained through foods and, in some cases, water.

Both vitamins and minerals are essential for maintaining good health.

Why Are Vitamins & Minerals Important?

Vitamins and minerals are involved in many essential processes throughout the body. They can help support:

Normal immune function
Healthy bones and teeth
Normal energy metabolism
Muscle and nerve function
Blood formation
Normal cell growth and repair
Brain and cognitive function
Overall health and well-being

Different nutrients have different functions, which is why consuming a varied diet is important.

Best Way to Get Vitamins & Minerals

A balanced diet containing a variety of foods is generally the best way to obtain essential vitamins and minerals.

Try to include a range of:

Fruits
Vegetables
Whole grains
Beans and legumes
Nuts and seeds
Dairy or suitable alternatives
Fish, eggs, and lean meats where appropriate

Eating different foods throughout the week can provide a wider range of nutrients along with fiber and other beneficial dietary components.

Do You Need Supplements?

Many people can obtain the vitamins and minerals they need from a varied and balanced diet. However, some people may need supplements because of their age, diet, pregnancy, lifestyle, medical conditions, or other individual circumstances.Supplements are not automatically necessary simply because a nutrient is important. Taking high doses of certain vitamins or minerals can also be harmful.If you think you may have a deficiency or are considering taking supplements, speak with a qualified healthcare professional or registered dietitian for personalised advice.

Signs of Possible Nutrient Deficiency

A nutrient deficiency can sometimes cause symptoms, but symptoms can vary depending on the nutrient and the individual.

Persistent tiredness or weakness
Changes in concentration
Frequent illness
Changes in skin or hair
Brittle nails
Poor wound healing
Muscle weakness or discomfort

Important to Remember

These symptoms can have many different causes, so they should not automatically be assumed to indicate a vitamin or mineral deficiency. If you have ongoing or concerning symptoms, speak with a healthcare professional.

How to Improve Your Nutrient Intake

You can support your vitamin and mineral intake with simple dietary habits:

Eat a variety of fruits and vegetables

Include different protein sources

Choose whole grains regularly

Add nuts, seeds, beans, and legumes

Choose nutrient-rich foods instead of relying heavily on highly processed foods

Drink enough fluids

Avoid unnecessarily restrictive diets

Follow professional advice if you have specific nutritional needs

The goal is to create a balanced eating pattern rather than focusing on one particular vitamin or mineral.

Vitamins, Minerals & Overall Health

No single vitamin or mineral can provide everything your body needs. Nutrients work together as part of a wider dietary pattern and healthy lifestyle.

Eating a variety of nutritious foods, staying physically active, getting adequate sleep, and maintaining regular healthcare when appropriate can all contribute to better overall health.
