Do you often feel tired, lifeless and lack energy? This affects your daily life a lot. It's hard to get out of bed, you barely get done what you need to do and you can't enjoy fun things. Maybe you have a vitamin deficiency.

Especially in the dark cold months, your energy levels could use a boost.

You can watch your diet and eat some more fruits and vegetables, but an easy way to help your body get some more energy is through vitamin supplements.

In this article, we'll tell you more about the different types of vitamins and minerals your body needs, how to notice a deficiency and what you can do about supplementing them.

Disclaimer: vitamin pills are not a panacea - there is no such thing. It can help you, but always make sure you use supplements responsibly and informed. When in doubt, consult a doctor.

Vitamin C

Vitamin C

Vitamin C is perhaps the best-known vitamin. It is also known as ascorbic acid. Vitamin C is an antioxidant: it protects your body cells from damage to connective tissue. You need vitamin C for the absorption of iron, the formation of connective tissue and maintaining your resistance.

Vitamin C is found in many fruits, vegetables and potatoes. Various types of cabbage, citrus fruits such as lemons and oranges, kiwis, berries and strawberries are particularly high in vitamin C. A vitamin C deficiency reduces your resistance, wounds may not heal properly and you may end up with scurvy. Too much vitamin C can cause intestinal problems or diarrhoea.

Vitamin C is water-soluble. To preserve the vitamin in vegetables as much as possible, it is best to cook them in little water for as short a time as possible. In an acidic substance such as orange juice, it is retained reasonably well. If you eat a healthy and varied diet, you will get enough vitamin C in most cases. When this is not the case, you can increase your intake with Vitamin C tablets.

Vitamin B12

Vitamin B12

Vitamin B12, also known as cobalamin, you need to make red blood cells. Those red blood cells carry oxygen in your blood. Vitamin B12 also ensures a properly functioning nervous system.

Vitamin B12 is found in animal products such as milk and dairy products, meat, fish and eggs.

If you eat vegan or vegan, it is recommended to take a vitamin B12 supplement or use products with added vitamin B12. In food, B12 is bound to a protein. In the stomach, this is detached by stomach acid. Then, in the small intestine, vitamin B12 binds to another protein. This coupling is necessary for vitamin B12 to be absorbed into the body. About 40-50% of the B12 you take in is actually absorbed by your body.

A deficiency in vitamin B12 can lead to anaemia.

This manifests itself in:

  • Fatigue
  • Dizziness
  • Palpitations
  • Tinnitus

It can also have neurological consequences such as memory loss and weak muscles.

Such a vitamin B12 deficiency is not common. This is because B12 is the only water-soluble vitamin that your body stores. So you often only notice it after you have been taking too little vitamin B12 for a long time. Your GP can diagnose this and determine how to solve it: when you have a deficiency, it is difficult to supplement with food alone. For example, the GP can prescribe vitamin B12 injections, or treat the deficiency with vitamin B12 supplements.

In people who take in too much vitamin B12, there are no known adverse effects. Your body takes care itself not to absorb too much vitamin B12.

It is not necessary for everyone to take extra vitamin B12. If you eat vegan or consume few animal products, however, it is recommended. Also, if it has been diagnosed by a GP, it may be a good idea to take extra supplements permanently.




Magnesium is a mineral you can find in cereal products, vegetables, nuts and dairy products, among others. Your body needs it for the formation of bones and muscles. It also ensures the transmission of stimuli through your muscles and nerves, the proper functioning of your muscles and energy production of the body's cells.

Magnesium deficiency is rare. In fact, magnesium is found in many different foods. When your kidneys or intestines do not work properly, however, a deficiency can occur.

The symptoms of magnesium deficiency are:

  • General lethargy and fatigue
  • Muscle cramps
  • Cardiac arrhythmias (in extreme cases)

It is difficult for a doctor to diagnose a magnesium deficiency. Only 1% of the magnesium in your body is in the blood. About half is in your bones and teeth and the rest in cells, muscles and organs.

Excess magnesium can only occur when taking magnesium tablets. At more than 250 milligrams a day extra, on top of magnesium from your diet, you may experience intestinal problems such as diarrhoea.

If you suspect you have a magnesium deficiency, you can take magnesium supplements or salts for this. This should be a maximum of 250 milligrams a day. When looking for a magnesium supplement, pay attention to what kind of magnesium it contains. Magnesium citrate is an easily absorbable form of magnesium in supplements. Other forms, such as magnesium oxide, are less well absorbed.

Caffeine pills


Caffeine is a substance found in coffee and in smaller amounts in tea. Caffeine is also found in energy drinks, cola, chocolate, chocolate milk and in some dietary supplements. In small amounts, caffeine can increase your alertness and concentration and improve your sports performance. Too much caffeine can give you symptoms such as restlessness, sleep problems, anxiety or headaches. This varies from person to person.

When you eat or drink something that contains caffeine, your body absorbs it quickly, almost completely. Caffeine stimulates your nervous system. It does not in itself give your body energy like fats, sugars or proteins do, but it can make you feel more energised. The substance adenosine in your brain normally makes you feel sleepy, but caffeine temporarily prevents your brain from getting this signal. You then temporarily experience less sleep pressure. If you take 100mg of caffeine at once or just before bedtime, it can affect your sleep.

For athletes, caffeine can help you get even more out of your sporting performance. your alertness and concentration increase, your stamina improves and it can make you feel the heaviness of your effort decrease.

To feel any effect, you need to take between 2 and 6 mg of caffeine per kilogram of body weight on average. The best time to take it depends on the type of sport you do and whether you take a drink, supplement or gum.

In general, it is safe to take a maximum of 200mg of caffeine at one time.

Our favourite caffeine pills

It is advisable to be careful with caffeine pills. This is because caffeine pills contain a high concentration of caffeine and you may not realise how much caffeine you are actually taking. A caffeine pill often contains 200mg of the substance, which is equivalent to about 5 cups of coffee. So when you take multiple pills, it can indeed be dangerous and cause poor circulation, palpitations, and in the worst case scenario, brain damage or a heart attack.

So read up carefully when you start using caffeine pills and never exceed the recommended dosage on the package. If you know exactly how much caffeine you are taking and you are not drinking 10 cups of coffee a day with it, you can feel free to use it.
