Micronutrients – The invisible heroes of your health

In a world where the temptation of keto, protein or intermittent fasting is ever-present, it’s easy to overlook the true conductors of nutrition: micronutrients. They provide hardly any energy themselves – but they release it. In this tiny universe, vitamins, minerals, trace elements and phytochemicals control every movement of your body. Whether you want to run a marathon, work with focus or simply make the most of your day – all of this requires these invisible directors. Here’s a quick overview of the different types:

Micronutrients include:

• – Vitamins (A, D, E, K, B-complex, C)
• – Minerals (magnesium, calcium, sodium, etc.)
• – trace elements (iron, zinc, selenium, iodine, chromium)
• – phytochemicals (polyphenols, carotenoids, flavonoids)

These ‘little heroes’ perform highly specialised tasks: enzyme activation, hormone regulation, cell protection, immune defence, cell renewal – and even the regulation of your genes.

And no matter what diet you follow – one gap often goes unnoticed: according to studies, 70 per cent of people in our region consume less than 80 per cent of their daily requirement of magnesium and zinc. This means the focus is no longer on exercise or diet, but on nutrients.

Your cells are not static building blocks. They are living, dynamic systems. This is where proteins are synthesised, energy is produced, waste is eliminated and DNA is repaired – and micronutrients play a central role in all of this.

Fancy some examples?

• – Magnesium (activates over 300 enzymes and is essential for almost every biochemical process in the body)
• – Vitamin C (protects your cells from oxidative stress and promotes collagen synthesis, which is essential for skin, tendons and blood vessels)
• – Zinc (affects wound healing, the immune system and even fertility)
• – Selenium (is a component of antioxidant enzymes such as glutathione peroxidase – your body’s own cellular defence shield)
• – Vitamin B12 (ensures proper nerve transmission and healthy blood formation)
• – Iron (is responsible for transporting oxygen in the blood – without it, you’d have no energy)

Micronutrients are found primarily in fresh, unprocessed foods. Each nutrient group has its own best sources, which you can specifically incorporate into your diet:

• Vitamins:
• – Vitamin A: liver, carrots, sweet potatoes, spinach, and many more
• – Vitamin C: e.g. citrus fruits, peppers, broccoli, berries, and many more.
• – B vitamins: wholemeal products, pulses, nuts, eggs, meat, and many more
• – Vitamin D: oily fish, egg yolks, mushrooms (exposed to sunlight), and many more

• Minerals:
• – Magnesium: almonds, spinach, porridge, bananas, and many more.
• – Calcium: Dairy products, kale, sesame seeds, almonds, and much more.
• – Sodium: Sea salt, vegetables, meat, and much more.

• Trace elements:
• – Iron: red meat, pulses, spinach, pumpkin seeds, and many more.
• – Zinc: beef, pumpkin seeds, cashews, cheese, and many more.
• – Selenium: Brazil nuts, fish, wholemeal products, and many more.
• – Iodine: Seaweed, iodised table salt, fish, and many more.

• Phytochemicals:
• – Polyphenols: Berries, green tea, dark chocolate, and much more.
• – Carotenoids: carrots, tomatoes, peppers, and many more
• – Flavonoids: citrus fruits, onions, apples, and many more

A balanced diet is the best way to obtain micronutrients. Nevertheless, in certain situations it may be advisable to use dietary supplements in a targeted manner – for example, in cases of increased requirements, deficiency states or specific life stages such as pregnancy or intense physical exertion.

In our affluent society, very few people consume too few calories. Yet many suffer from ‘hidden hunger’ – micronutrient deficiencies that are barely noticeable but have serious consequences.

The following are particularly critical today:

• – Vitamin D (because we often do not spend enough time in sunlight)
• – Magnesium (which is quickly lost through stress, exercise and sweating)
• – Omega-3 fatty acids (as diets often contain too much omega-6 and fish consumption is too low)
• – Iron and zinc (particularly with plant-based diets or in cases of digestive problems)
• – Iodine and selenium (the availability of which depends heavily on regional soil conditions)

Symptoms are usually non-specific: fatigue, listlessness, difficulty concentrating, sleep disturbances, susceptibility to infections or hair loss – often nobody thinks of micronutrients, neither those affected nor doctors.

In theory, you can get all your micronutrients from your diet. In practice, this is often more difficult, because:

Particularly within our active community, where standards are high, it is important to understand that switching to a diet rich in micronutrients does not have an immediate effect. The body needs time to replenish itself, for cell regeneration and to readjust enzyme levels. This often takes weeks or even months.

This is not an excuse, but a biological reality. Anyone expecting a transformation in their skin after just a week of green smoothies will be disappointed. Those who stick with it will usually experience noticeable improvements after 8 to 12 weeks: more energy, better concentration, a stronger immune system and more restful sleep.

Recreational athletes also benefit enormously: faster recovery, fewer muscle cramps, better sleep quality and a more stable mood thanks to B vitamins, magnesium and omega-3. Fitness isn’t just about training – fitness is cellular function.

Micronutrients are not supporting actors, but the unsung heroes. Those who focus solely on calories and macronutrients often overlook what keeps the body fundamentally fit, resilient and healthy. Whether in a crisp kale salad, a handful of almonds or a succulent piece of salmon – these invisible heroes are waiting everywhere to be put to good use.

And best of all: by supplying your body with micronutrients, you’re investing in long-term energy, recovery and cell protection.

You might be wondering: what actually happens to all these micronutrients once they’ve reached your body? The answer is fascinating: they act as both builders and bodyguards. Some repair damaged cell walls, others protect your DNA from attacks by free radicals, or control how quickly your cells renew themselves. This is exactly where the next part of our series comes in: Cell protection & Cell Renewal – How Micronutrients Heal Your Body from Within. There, we’ll delve deep into the invisible world of your cells and show you how nutrition makes the difference between rapid ageing and sustainable regeneration.”
