What Are Micronutrients?

October 7, 2023

Step into the intriguing universe of micronutrients! Although these nutritional powerhouses are tiny, their impact on our health is immense. Micronutrients are the unsung heroes of nutrition, sometimes overlooked but absolutely essential for our bodies to function optimally. Unlike macronutrients (carbohydrates, proteins, and fats), which are required in larger quantities, micronutrients are needed in smaller amounts. But don’t let their size fool you – their impact is immense. Throughout this blog, we will venture into the intricate world of micronutrients, uncovering their definition, understanding their vital roles, and learning where to discover them. Get ready for an exciting expedition through the fascinating microscopic wonders that have a significant impact on our health and overall well-being!

Micronutrients Defined

Micronutrients encompass vitamins and minerals, each with its unique role in supporting various bodily functions. Vitamins are organic compounds that help regulate processes like metabolism and cell function. On the other hand, minerals are inorganic elements vital for building bones, transmitting nerve signals, and more.

The A-Listers: Vitamins

Vitamins are like the celebrities of the nutrition world, each playing a specific role to keep us in top-notch condition. To put it more scientifically, vitamins are essential organic substances that our bodies require in small amounts to perform various vital functions. These micronutrients are critical for overall health, helping with processes such as metabolism, immune response, and cell growth. Vitamins are divided into two main types: water-soluble vitamins (like Vitamin C and B-complex vitamins) that dissolve in water and need to be replenished regularly, and fat-soluble vitamins (such as Vitamins A, D, E, and K) that are stored in the body’s fat and released when needed.

The Rockstars: Minerals

Minerals are the unsung rockstars that provide the backbone to our health. Minerals are essential inorganic nutrients crucial for maintaining human health and functioning. They play fundamental roles in various bodily processes, from bone formation and nerve signaling to immune system support and oxygen transport. Some key minerals include, but not limited to, calcium, vital for strong bones and teeth. Iron, essential for oxygenating the blood, potassium, important for heart and muscle function. Zinc, necessary for immune response and wound healing. Magnesium, a multitasking powerhouse, plays a role in muscle contraction and relaxation, facilitating a healthy nervous system, bone and heart health, free radical protection, energy production and blood pressure. Some other critical minerals include phosphorus, copper, sodium, manganese, selenium, and iodine, each contributing to different aspects of our well-being and health. 

Diet Rich Sources 

So, how can we ensure we’re getting our daily dose of these pint-sized powerhouses? Let’s take a peek at some sources!

Colorful Fruits and Veggies

A plate full of colorful fruits and vegetables is like a micronutrient treasure trove. The rich pigments are indicative of the high levels of antioxidants, particularly phytochemicals like flavonoids, carotenoids, and anthocyanins, which provide a wide array of advantages for our well-being. These antioxidants help combat oxidative stress, neutralize harmful free radicals, and reduce inflammation in the body, thereby reducing the risk of chronic diseases such as heart disease, diabetes, and certain types of cancer.

Moreover, these colorful fruits and vegetables are abundant in essential vitamins, and minerals. Vitamins like A, C, and E are prevalent, promoting immune function, skin health, and vision. While minerals such as potassium, folate, and iron present in substantial amounts, help support heart health, DNA synthesis, and oxygen transport in the blood. 

Incorporating hyper-pigmented fruits and vegetables, such as berries, carrots, spinach, purple cabbage, bell peppers, sweet potatoes, and beets, into our daily diet can contribute significantly to our overall health and longevity. The diversity of nutrients and health-boosting properties they offer make them an essential component of a well-rounded and nutritious diet.

Cruciferous vegetables

Cruciferous vegetables, such as broccoli, cabbage, cauliflower, Brussels sprouts, and kale, deserve their spotlight as well, as they contain a very important group of compounds called glucosinolates. When we consume these vegetables, glucosinolates are broken down into bioactive compounds like indoles, isothiocyanates, and sulforaphane. These compounds have been linked to inhibiting the growth of cancer cells and reducing the risk of breast, prostate, lung, and colon cancer. Glucosinolates are also recognized for their potential in supporting the body’s detoxification processes, particularly in the liver, aiding in the elimination of harmful substances and promoting overall liver health. Additionally, research suggests that these compounds may have anti-inflammatory, antioxidant, and antimicrobial effects, further contributing to their positive impact on human health. Incorporating cruciferous vegetables into our diet provides a natural and flavorful way to harness the benefits of glucosinolates and support our overall well-being.


Grass-finished dairy products are praised for their superior nutritional profile and potential health benefits. Cows that graze on grass produce dairy enriched with a higher potency of fat-soluble vitamins such as A, E, and K2, which are crucial for immune function, vision, heart and bone health. 

Milk, cheese, yogurt, and other dairy items are packed with calcium, a mineral essential for building and maintaining strong bones and teeth. Calcium also plays a significant role in muscle function, nerve signaling, and blood clotting. Butter in particular provides a moderate amount of Vitamin D, which aids in calcium absorption and supports bone health. Vitamin D is also essential for immune function and helps regulate mood. Additionally, dairy provides Vitamin A, Vitamin E and B vitamins, including B2 (riboflavin), B12 (cobalamin), and B5 (pantothenic acid), which contribute to energy production, red blood cell formation, and metabolism. 

Lean Protein and Organ Meat 

Organ meats, often considered superfoods, provide a rich array of nutrients. Liver, for instance, is abundant in Vitamin A, as well as B vitamins like B12, which supports nerve function and energy metabolism. Animal protein, including lean cuts of meat, offers iron for oxygen transport, zinc for immune support, and various B vitamins for overall well-being. If you’re looking for a few easy high protein recipes, download our eBook: 5 quick and healthy high protein recipes!

Fish and Seafood 

Fish, particularly fatty fish like salmon and mackerel, are excellent sources of Vitamin D. Canned sardines deserve extra praise for calcium as their edible bones provide an abundance of it that is easily absorbed! Fish also provide essential minerals like selenium, which acts as a powerful antioxidant, protecting cells from damage and supporting the immune system. It is also a good source of iodine, vital for thyroid function and metabolism. Fish contains phosphorus, crucial for bone health and energy metabolism, and various B vitamins, including B12. 

Let’s not forget the other food living in the sea. Shellfish and crustaceans are also marine delicacies that offer an abundance of essential micronutrients, making them a valuable component of a well-rounded diet. One standout micronutrient found in shellfish is zinc, a mineral essential for immune function, wound healing, and DNA synthesis. Additionally, shellfish provide a significant amount of Vitamin B12 and selenium, an antioxidant that helps protect cells from damage and similarly to iodine, supports our thyroid.

Furthermore, shellfish are a good source of iron, necessary for oxygen transport in the blood, and other crucial minerals like magnesium, selenium, phosphorus, iodine, and potassium, each playing vital roles in supporting metabolic processes, immune response, vision, and bone health.


Let’s swim back up to land for a bit and talk eggs. Eggs are an excellent source of Vitamin B12, and choline, a nutrient predominantly found in the egg yolk, that supports our brain health, liver function, and fetal development during pregnancy. Eggs also provide use with selenium, Vitamin A and B vitamins like riboflavin, pantothenic acid, and folate. With their impressive nutrient profile and high bioavailability, incorporating eggs into a well-rounded diet can significantly enhance our intake of essential vitamins and minerals, promoting optimal health and vitality.

Other food sources high in micronutrients that are worth mentioning include: nuts, seeds, legumes, whole grains and unrefined/minimally processed oils such as: extra virgin olive oil and coconut oil, and grass-finished ghee (one of my faves). 

What are Micronutrients?

Micronutrients: vitamins and minerals – are the unsung heroes that form the cornerstone of our well-being. Despite being required in smaller quantities, their impact on our health is immense. From fortifying our immune system, supporting bone health, and ensuring efficient energy metabolism to aiding in mental clarity and even protecting against chronic diseases, these minuscule powerhouses are indispensable and we cannot exist without them.
