We are all familiar with stress: a busy schedule, deadlines, worries or unexpected events. What many people do not realise is that stress is not only mentally taxing, but also affects your nutritional status. When you are stressed, your body uses more vitamins and minerals than normal. Eating well and taking the right supplements can make a world of difference. We investigated which vitamins and minerals are important and when supplementation can be beneficial.

What is stress?
Stress is a natural, biological response to a situation that you perceive as threatening or challenging. As soon as your brain signals danger, the sympathetic nervous system becomes active: the familiar fight-or-flight response. The adrenal glands are indispensable players in this stress response. These small glands on top of your kidneys produce stress hormones such as adrenaline, noradrenaline and cortisol.
Cortisol provides extra energy so that you can respond immediately to the stressful situation. Your heart rate increases, you start to sweat and your muscles tense up. In primitive times, this helped us to escape from predators; nowadays, the same thing happens during an important presentation, for example. Your brain does not distinguish between physical and mental threats: it always puts you on high alert.
A short stress response is not bad in itself. On the contrary: it can make you alert, improve your performance and help you make quick decisions. But when stress lasts too long, your body remains in “on mode”. This depletes your energy reserves, disrupts your hormone balance and can lead to physical and mental complaints.
How does stress affect your vitamin requirements?
The stress hormones cortisol and adrenaline help you stay alert, but they also require a lot of energy and can affect the absorption and processing of nutrients. When the sympathetic nervous system is active, digestion becomes less of a priority. As a result, food is broken down less effectively and vitamins and minerals are absorbed less efficiently. At the same time, the need for antioxidants and minerals increases. This causes your reserves to be depleted more quickly and you may experience fatigue, reduced immunity and concentration problems.
Signs that you need extra support
Sometimes your body gives you signals that your adrenal glands or energy levels could use some extra support. This can manifest itself in persistent fatigue that does not go away, even after sufficient rest. Problems with concentration or memory can also be a sign that your stress levels are too high. Recurring colds or infections indicate that your immune system is under pressure. In addition, muscle tremors, cramps or insomnia may indicate that your mineral or electrolyte balance is disturbed. By being alert to these signals, you can take timely measures to support your body with the right nutrition and supplements.
Key vitamins and minerals for stress
- Vitamin C
Vitamin C is a powerful antioxidant that helps keep your immune system strong. The adrenal glands contain one of the highest concentrations of vitamin C in the entire body, because they use this vitamin to produce cortisol. During stress, your consumption increases, which means you can develop deficiencies more quickly.
Foods rich in vitamin C are mainly fruit and vegetables, such as peppers, kiwis, oranges and broccoli. - Vitamin B complex
B vitamins are essential for your energy production and nervous system. They help your body to balance stress hormones and support your concentration. B5 (pantothenic acid) and B6 (pyridoxine) in particular play a key role in energy production and the production of stress hormones. When you are stressed, you use up these vitamins more quickly, which can lead to fatigue and mood swings. Vitamin B6 also works closely with magnesium.
B vitamins are mainly found in whole grains, legumes, nuts, seeds and green leafy vegetables. - Magnesium
Emotional or physical stress increases magnesium consumption in our bodies. You may notice that during times of stress, you tense certain muscles, such as your jaw, abdomen or shoulders. This is different for everyone, but the effect is the same: your muscles need more magnesium to function properly.
Magnesium is known as the “relaxation mineral”. It helps muscles to relax, supports sleep quality and is involved in more than 300 enzyme processes in the body. Magnesium can help in stressful situations, while a magnesium deficiency can actually increase your sensitivity to stress, creating a vicious circle.
Magnesium-rich foods include pumpkin seeds, almonds, bananas, spinach and dark chocolate. However, a supplement is often necessary in case of a deficiency because it is difficult to get enough magnesium from food and our soil contains much less magnesium than it used to. - Omega-3 fatty acids
Omega-3 fatty acids play an important role in the health of your brain and nervous system, which directly affects how your body deals with stress. They are essential for building cell membranes in the brain and help with communication between nerve cells. This allows signals about stress and emotions to be transmitted more efficiently, contributing to better stress resistance.
Omega-3 fatty acids can also help regulate inflammatory processes in the body. Chronic stress can increase inflammatory responses in the body, contributing to fatigue, mood swings and weakened immunity. Studies also show that omega-3 supplementation can help regulate the production of stress hormones such as cortisol. In addition, omega-3 fatty acids have even more health benefits.
Omega-3 is mainly found in oily fish. Plant sources of omega-3 include algae oil, linseed, chia seeds, hemp seeds and walnuts. - Zinc
Zinc supports hormone production, cell repair and the immune system. Chronic stress causes zinc to be used up more quickly, which can lead to reduced immunity and slower wound healing.
Good sources of zinc include oysters, pumpkin seeds, chickpeas, lentils and cashews.
Electrolytes (sodium, potassium, chloride)
Prolonged stress can disrupt the salt balance because cortisol affects sodium and fluid levels. A lack of electrolytes can lead to tiredness, dizziness, and muscle weakness.
You can prevent this by drinking water with a little bit of Celtic salt (also called Sole). Celtic sea salt is less processed than other types of salt, which means it retains its natural minerals and trace elements. Diluted broth and coconut water are also good for replenishing deficiencies.
Electrolytes are not only important during prolonged stress, but also in hot weather, after a visit to the sauna, when you are ill or when you are exercising intensively.
Supplementation: when and how?
Sometimes a healthy diet alone is not enough to meet all nutritional needs, especially during prolonged stress, a busy lifestyle or limited food choices. In such cases, a supplement can help replenish deficiencies in vitamins, minerals and other important nutrients. For example, if you do not eat oily fish twice a week, an omega 3 supplement with algae oil is recommended. For minerals such as magnesium or zinc, absorption is often better in easily absorbable forms, such as magnesium bisglycinate.
When choosing supplements, pay attention to quality: avoid unnecessary additives, synthetic fillers or artificial colourings, and choose easily absorbable and bioavailable forms. The time of intake can also influence the effect: some vitamins work better with a meal (such as omega-3), while others can be absorbed on an empty stomach. A supplement can be a valuable support, but it never replaces a varied and nutritious diet. When you are stressed, your body also needs sufficient carbohydrates, proteins and fats, and eating too little makes stress worse.
More than vitamins
Vitamins are important when you are stressed, but lifestyle also plays a major role. You don't want your sympathetic nervous system to remain active; you want your parasympathetic nervous system to have a chance to recover. This has a major effect on your digestion and overall health.
That is why it is important to build in moments of relaxation after exercise. Think of sufficient (and good quality) sleep, daily exercise, breathing exercises, pleasant social contacts and enough time for activities that recharge you.

Conclusion
Stress places high demands on your body and your vitamin and mineral reserves. By consciously ensuring you get enough vitamin C, B vitamins, magnesium, omega-3 and zinc, you can help your body cope better with tension and stress. Combine this with sufficient rest and relaxation, and you will build a solid foundation for more energy and resilience!
