Zinc also benefits physical aspects of our health. It helps maintain healthy bones, hair, nails, and skin.

It's necessary for normal vision and plays a protective role for cells from oxidative stress. It even supports the normal function of our immune system.

Lastly, zinc is involved in the process of cell division, another testament to its role in growth and repair.

Vitamin A, an essential nutrient for humans, contributes significantly to a variety of bodily functions. It plays a critical role in normal iron metabolism, facilitating the process in which the body uses iron to carry out essential functions like oxygen transportation.

Vitamin A is also crucial for maintaining the health of normal mucous membranes, the linings that protect the body's internal surfaces. In addition, this vitamin plays a key role in maintaining the health of the skin, offering support for both its structure and function.

A significant contribution of Vitamin A is its role in maintaining normal vision. It is an essential component of the pigments in the retina, which capture light and enable vision.

Furthermore, Vitamin A contributes to the normal function of the immune system, supporting the body's defense against illness.

Finally, Vitamin A plays a role in the process of cell specialisation, a fundamental aspect of growth, development, and ongoing bodily maintenance.

Vitamin C plays a vital role in our health, particularly in maintaining the normal function of our immune system during and after intense physical exercise.

It contributes to the formation of collagen, necessary for the regular function of various parts of our body - blood vessels, bones, cartilage, gums, skin, and teeth.

Vitamin C supports normal energy-yielding metabolism, which is essential for our daily activities. It also contributes to the proper functioning of our nervous system and normal psychological function, impacting our overall wellbeing.

Vitamin C is instrumental in the protection of cells from oxidative stress, reducing tiredness and fatigue. It plays a key role in regenerating the reduced form of vitamin E and enhances iron absorption, ensuring our body functions optimally.

Vitamin E is a powerful antioxidant that plays a crucial role in our body. It contributes to the protection of cells from oxidative stress, which occurs when there is an imbalance between harmful free radicals and the body's natural defense mechanisms.

Oxidative stress can occur as a result of various factors such as pollution, stress, unhealthy lifestyle habits, and exposure to harmful substances. When there is an excess of free radicals in the body, they can cause damage to cells, DNA, and other important structures. This damage is often associated with aging, inflammation, and the development of various diseases.

Vitamin E helps to neutralize free radicals and protect cells from their damaging effects. By doing so, it supports overall cellular health and contributes to the maintenance of healthy tissues and organs.

You can find vitamin E in various food sources, including nuts and seeds (such as almonds, sunflower seeds, and hazelnuts), vegetable oils (such as olive oil and sunflower oil), spinach, broccoli, and avocados. Including these foods in your diet can help ensure an adequate intake of vitamin E.

It's important to note that while vitamin E is beneficial for our health, it's always recommended to consult with a healthcare professional for personalized advice, especially if you have specific dietary needs or concerns.

Iodine is a vital mineral found notably in seafood and dairy products. Its contributions are critical for various aspects of our health.

Iodine supports normal cognitive function, playing an integral role in information processing and memory maintenance. This crucial mineral aids in maintaining mental sharpness and clarity.

It's also involved in energy-yielding metabolism, converting food into energy. This function makes iodine vital for maintaining consistent energy levels, contributing to our overall vitality and endurance.

Furthermore, iodine sustains the normal functioning of the nervous system. It promotes smooth transmission of signals between nerve cells, ensuring our body’s coordination and reflexes function properly.

Notably, iodine contributes to the maintenance of normal skin. By aiding in cell regeneration, it ensures our skin stays healthy and rejuvenated.

Last but not least, iodine plays a key role in enabling normal thyroid hormone production and thyroid function. The thyroid gland uses iodine to produce hormones that regulate metabolic processes, emphasizing iodine's importance in our overall well-being.

Vitamin D plays an essential role in various physiological processes. It's fundamental for the normal absorption and utilisation of calcium and phosphorus, two minerals critical for maintaining bone health and various metabolic functions. Vitamin D's role in maintaining normal blood calcium levels further highlights its importance in bone health.

Its role extends to maintaining normal bones, teeth, and muscle function, illustrating its diverse benefits across the body. Strong teeth and bones, and well-functioning muscles are part of the overall health and wellness picture that vitamin D helps support.

Moreover, vitamin D is vital for the normal function of the immune system, demonstrating its importance in defending against illnesses. Intriguingly, vitamin D also has a role in the process of cell division, further underlying its significance in growth and development.
