Introduction

Did you know that the tiny nutrients we may often overlook, vitamins and minerals, are the unsung heroes of our body, controlling everything from energy levels to immunity? Despite being needed in small amounts. These nutrients play a crucial role in maintaining overall health and wellbeing. They are involved in a wide range of bodily functions such as metabolism, bone health, immunity, and energy production. While vitamins are required in small amounts, minerals are inorganic elements which are vital for a variety of psychological processes. A balanced intake of these nutrients is necessary for optimal bodily functions and to prevent deficiencies that can lead to various health problems.

Vitamins are categorized into two parts: fat soluble (vitamin A, D, E, and K) and water soluble (vitamin C and B-vitamins). On the other hand, minerals are divided into major minerals like calcium, magnesium, potassium and trace elements like zinc and iodine. Each vitamin and mineral has specific functions that contribute to health ranging from immunity development, supporting nerve function and promoting bone, teeth and skin health.

The deficiencies of these vitamins and minerals manifest their symptoms in various forms such as fatigue, weakened immunity, bone disorder and impaired cognitive functions. To detect these deficiencies, healthcare professionals use a range of diagnostic tests. Overall, identifying deficiencies will allow for timely interventions, including dietary adjustments or supplementation to restore balance and prevent long term health applications.

1. Vitamins and their functions

Vitamins are essential nutrients that the body needs to perform a wide range of functions, from boosting the immune system to promoting cell growth and repair. They are organic compounds, which contain carbon and hydrogen and are needed in small amounts to maintain health. Our body cannot produce most vitamins on its own, they must be obtained from food or vitamin supplements.

Vitamins are classified into two groups:

  1. Water-soluble vitamins
  2. Fat-soluble vitamins

1.1. Water-soluble vitamins

Water-soluble vitamins are those vitamins that dissolve in water and are not stored in the body. As the body does not store them, they need not be consumed regularly through diet or supplements. Any excess amounts are typically excreted in urine, which means the body needs a constant amount to maintain proper function. They are not likely to reach toxic levels. Most vitamins are water-soluble. These include vitamin C and eight B vitamins.   

1.1.1. Vitamin C (Ascorbic acid)

Vitamin C is a powerful antioxidant which is important for maintenance of connective tissues and collagen production. It has two forms: ascorbic acid and an oxidized form of ascorbic acid called dehydroascorbic acid.

Vitamin C function
  • Antioxidant defenses: vitamin C prevents our body against oxidative stress by working as an antioxidant.
