Vitamins and minerals are essential nutrients that play key roles in nearly all bodily functions. They are needed in small quantities but have a major impact on our health. Unlike macronutrients such as carbohydrates, proteins, and fats, which provide energy, vitamins and minerals do not provide energy themselves. However, they help the body use the energy produced by macronutrients. Here are some of their main functions:

1. Immune system support.

Vitamins like vitamin C, vitamin D, and certain minerals like zinc and selenium strengthen the immune system, helping the body fight infections and diseases.

2. Bone health.

Nutrients such as calcium, vitamin D, and phosphorus are essential for developing and maintaining bone density and health, reducing the risk of diseases such as osteoporosis.

3. Energy production.

The B complex vitamins play a crucial role in cell metabolism, helping the body convert food into energy. Magnesium is also important for energy production.

4. Skin and eye health.

Vitamin A, for example, is essential for the health of the skin and eyes. It helps maintain normal vision and contributes to skin regeneration.

5. Brain function.

Nutrients like iron, magnesium, B vitamins, and omega-3 fatty acids support brain function, improving memory, concentration, and other cognitive functions.

6. Cell repair and growth.

Vitamins and minerals are involved in cell repair and growth. Vitamin C, for example, is essential for wound healing, while vitamin E plays a role in protecting cells against oxidative damage.

7. Cardiovascular health.

Some minerals, like potassium, help regulate blood pressure, while magnesium can play a role in preventing heart diseases.

8. Hydration and electrolyte balance.

Minerals such as sodium, potassium, and chloride help regulate the body's hydration balance, essential for nerve and muscle function.

Vitamins and minerals are therefore fundamental for a healthy and active life. They allow our body to function efficiently, support the immune system, contribute to bone health, and play a role in nearly all bodily functions. A balanced diet, supplemented if necessary by quality products like those offered by QNT, can help ensure an adequate intake of these essential nutrients, allowing everyone to unleash their full potential and become the best version of themselves.
