You get enough sleep, you are not working more than usual, and yet this fatigue does not go away. It has settled in, become normalized, and is beginning to affect your daily life. Before accepting that you have to live with it, it is worth looking for a metabolic cause - particularly deficiencies.
Understanding chronic fatigue
“Normal” fatigue disappears with rest. Chronic fatigue, on the other hand, persists despite sufficient sleep. It can manifest in different ways: physical fatigue (difficulty exerting yourself), mental fatigue (brain fog, difficulty concentrating), or a lasting lack of motivation.
Its causes are numerous: prolonged stress, an intense lifestyle, a diet lacking in micronutrients, but also - very frequently - deficiencies in specific vitamins and minerals. These deficiencies are often invisible to the naked eye but have a real impact on cellular and nervous system function.
The most common deficiencies behind fatigue
Iron is the most widespread deficiency, particularly among women of childbearing age. Iron is the central component of hemoglobin, which transports oxygen throughout the body. A lack of iron reduces the oxygen supply to cells, causing significant physical fatigue, dizziness, and pale skin.
Vitamin D is deficient in the majority of French people during winter. It plays a key role in the functioning of the immune and nervous systems. A deficiency is associated with diffuse fatigue, low mood, and increased susceptibility to infections.
Magnesium is involved in cellular energy production (ATP). A deficiency causes nervous fatigue, muscle tension, and difficulty sleeping deeply.
B vitamins (B1, B2, B3, B5, B6, B9, B12) contribute to energy production, nerve signal transmission, and cell renewal. B12 in particular is often insufficient in people following a vegetarian or vegan diet.
Rhodiola (Rhodiola rosea) is not strictly speaking a nutrient, but an adaptogenic plant that helps the body better manage fatigue related to overwork. It promotes the reduction of nervous fatigue associated with excessive mental strain.
How can you identify your deficiencies?
The only way to confirm a deficiency is through a blood test. A check-up including a complete blood count (for iron), 25-OH vitamin D levels, and red blood cell magnesium will give you an accurate picture. Talk to your doctor about it.
In the meantime, if you suffer from persistent fatigue despite a healthy lifestyle, a broad-spectrum supplement at physiological doses may be an informative first step.
The Epycure solution for restoring your energy
The Epycure Multivitamin+ Course (also known as “Essential Anti-Fatigue”) was designed to address all forms of fatigue by providing the 15 essential active ingredients the body may lack. Its star ingredient is rhodiola (Rhodiola rosea), which promotes the reduction of nervous fatigue associated with excessive mental strain.
The complete formula combines:
- Iron + Vitamin C - iron contributes to normal oxygen transport and helps reduce fatigue; vitamin C improves its absorption and also helps reduce fatigue
- Magnesium - helps maintain normal psychological functions and helps reduce fatigue
- Vitamins B1, B2, B3, B5, B6, B9, B12 - contribute to the normal functioning of the nervous system and normal psychological functions
- Vitamin D3 - contributes to the normal functioning of the immune system
- Zinc and selenium - contribute to the normal functioning of the immune system and help protect cells from oxidative stress
- Spirulina - a natural source of protein, plant-based iron, and vitamins
The formula is suitable for vegetarians and vegans (lichen-derived vitamin D3, active vitamin B12, spirulina), made in France in an AFNOR HACCP+-certified laboratory, and contains 81.4% ingredients of natural origin.
Timeline of effects: from day 15, renewed energy and motivation. By day 30, reduced physical fatigue and improved concentration. By day 90, improved mental well-being and a strengthened immune system.
Results from Lab'Epycure (34 volunteers, 3 months): 1 in 2 people felt less overworked after 30 days, 97% felt in better physical and mental shape, and 97% noticed an improvement in their mood.

In summary
Persistent fatigue is rarely inevitable. In many cases, it is caused by identifiable and correctable deficiencies. A medical check-up, a diet richer in micronutrients, and well-targeted supplementation can completely transform your daily energy levels. Fatigue is not your natural state. It is possible to overcome it.
