Micronutrients are those essential nutrients we require in relatively small quantities but play a vital role in regulating how our bodies work on a cellular and chemical level, normally measured in milligram (mg), microgram (μg) and International Unit (IU).

They are not made in the body, or only in insufficient amounts, and are mainly obtained through foods; various types of chemicals including vitamins, minerals, antioxidants, phytonutrients and other nutritional factors.

Why do we need  micronutrients?

Micronutrients are incredibly important for health and wellness because they protect our bodies from disease, ensure normal metabolism, reduce oxidative stress, help every system in body function properly and slow aging process.

Many micronutrients are considered “essential nutrients,” which means they are not made in the body. In fact, humans need more than 50 different types of micronutrients for optimum health. Because our bodies are very complex and have brain capacity beyond other animals; we need higher levels of many micronutrients in order to fuel every system including digestive system, reproductive system, nervous system, immune system and so on.

How much do we need?

Without proper consumption of micronutrients, we will risk micronutrient deficiencies, such as scurvy (lack of vitamin c), rickets (lack of vitamin D), osteoporosis (lack of calcium), and anemia (lack of iron).

So what is the daily intake amount for each micronutrient to prevent deficiency diseases? And what are the optimum nutrient intake levels which are associated with the highest health ratings?
