The 5 most effective vitamins against fatigue

Vitamins play an essential role in energy metabolism

The proper functioning of energy metabolism is largely based on the action of vitamins and minerals in the body.

These micronutrients take part in numerous biochemical reactions involved in energy production.

In particular, vitamins are involved in converting the carbohydrates, fats and proteins we consume into energy that can be used by our cells (1).

An adequate intake of vitamins therefore helps to prevent dietary deficiencies and provides effective support for physiological functions, so that we maintain a good level of energy throughout the day.

That's why a course of vitamins to combat fatigue can be so beneficial.

Each vitamin has its own mechanism of action, offering benefits that vary from one to another.

Some, however, are better at reducing the feeling of tiredness and improving overall vitality, particularly during periods of stress, overwork or convalescence.

List of the 5 vitamins effective against fatigue

Vitamin B12: an essential ally against fatigue 

Essential for the body to function properly, vitamin B12 helps to reduce fatigue. It contributes to normal energy metabolism by playing a part in the energy production processes that cells use on a daily basis (2).

What's more, its involvement in the normal functioning of the nervous system and in maintaining normal psychological functions makes it a valuable support during periods of stress or low morale (3).

Vitamin B12 also contributes to the normal formation of red blood cells, which are essential for transporting oxygen around the body, particularly to the muscles, and can therefore have an impact on feelings of physical fatigue.

Finally, it plays a part in the normal functioning of the immune system. This is essential for fighting viral and bacterial infections, which are major sources of fatigue.

As bioavailable vitamin B12 is mainly found in foods of animal origin, it is very important to ensure that you are getting enough if you eat little or no meat.

In all cases, a dietary supplement containing this vitamin is ideal for enriching your diet (like our Methylcobalamin supplement).

Vitamin B9 (folic acid): invaluable daily support

Vitamin B9, or folic acid, is naturally present in various foods, where it's referred to as folate and is known to contribute to reducing fatigue.

Folates contribute to the normal metabolism of homocysteine. When this process functions properly, it helps prevent an excess of homocysteine in the blood, which has been linked to fatigue and cognitive problems (4).

Folates are also involved in the normal formation of blood. Since red blood cells are essential for the proper oxygenation of tissues, they can affect feelings of vitality and physical performance.

Folates also help maintain normal psychological functions. In particular, they are involved in the synthesis of certain neurotransmitters (such as serotonin and dopamine) (5), which influence motivation and resistance to stress.

To increase your intake of vitamin B9, it may be a good idea to turn to a dietary supplement that contains it in a form that can be rapidly used by the body (such as our SuperFolate supplement, with its immediate bioavailability).

Vitamin C: an energising superstar that needs no introduction

Vitamin C is a popular choice when it comes to natural boosters, as it helps reduce tiredness and supports daily well-being.

It plays an important role in maintaining normal energy metabolism, particularly by increasing the absorption of iron (6), an essential mineral found in food. Iron is necessary for the formation of red blood cells, which are responsible for transporting oxygen to the body’s cells.

Vitamin C also contributes to the normal functioning of the immune system. An active immune system makes it easier to resist infections, which are often associated with a drop in energy.

Finally, vitamin C helps to protect cells against oxidative stress, a phenomenon that impairs their efficiency. By protecting them from its harmful effects, its antioxidant properties help to maintain their proper functioning and vitality.

Certain forms of vitamin C are more effective than others in ensuring that supplementation achieves its goal. Liposomal vitamin C, for example, is formulated for maximum absorption by the body (see Liposomal Vitamin C).

Certain forms can also be complementary (which is why we have combined 3 synergistic forms of vitamin C in our Triple C formula).

Finally, some forms are more stable and powerful than others (such as the phosphorylated ascorbate in our Asc2p Vitamin C supplement).

Vitamin D: essential for energy and immunity

Vitamin D also contributes to the normal functioning of the immune system (8).

This is particularly important in the fight against winter infections, when the body synthesises less vitamin D because the skin is less exposed to the sun.

Vitamin D is also involved in the process of cell division. It therefore supports cell renewal, including that of the nervous system, which plays a role in our perception of fatigue.

Although it is not directly involved in energy production like certain B vitamins, various studies have shown that insufficient levels of vitamin D are correlated with chronic fatigue and a drop in energy levels (9).

This is why supplementation is particularly recommended for people prone to seasonal fatigue or living in areas with little sunshine (for example, by taking our Vitamin D3 2000 IU Spray supplement).
