Taking the right supplements at the right doses and in the right forms are important to ensure that these health supplements do indeed supplement health and not cause harm to the body.
The fresh food which makes up a healthy diet contains a variety of nutrients for good health—some of them are essential for the human body to function and maintain homeostasis.
In general, there are two types of nutrients, macronutrients and micronutrients. Macronutrients include carbohydrates, protein and fat, while micronutrients range from vitamin A, Bs, C, D, E to minerals such as magnesium, iron, calcium as well as essential fatty acids. In the past, diet was the primary source of these nutrients. Perhaps this was the reason that despite different cultures having different types of food, one thing they all have in common is each of this diet consists of wide variety of foods to ensure that the body receives enough nutrients it requires.
It was not until 1912, when Polish-born biochemist Casimir Funk came across ‘mysterious’ compounds he named vital amines, which then shortened to vitamins that the significant health effects of micronutrients began to be understood and studied further.
