You sleep for 8 hours, but you wake up exhausted. You take breaks, but the fatigue does not go away. You are not alone: persistent fatigue affects millions of people, and in most cases, it is not linked to a lack of sleep, but to silent nutritional deficiencies.
Why feel tired despite getting enough sleep?
Persistent fatigue - also called asthenia - is often a sign that the body lacks nutrients essential for cellular energy production. Cells produce energy through complex processes that require cofactors: vitamins, minerals, and amino acids. Their absence slows down or blocks the ATP production chain, the fuel that powers our cells.
The deficiencies most frequently involved:
- Iron: essential for transporting oxygen in the blood. Even a mild deficiency causes persistent physical and mental fatigue.
- B vitamins: B1, B2, B3, B5, B6, B9, and B12 all contribute to normal energy metabolism. Deficiency is common among people under stress, vegetarians, and women of childbearing age.
- Magnesium: magnesium helps reduce fatigue and is involved in more than 300 enzymatic reactions. 75% of French people consume less than the recommended amounts.
- Vitamin D3: contributes to the maintenance of normal muscle function. A deficiency is associated with general fatigue and low spirits.
- Vitamin C: helps reduce fatigue and promotes the absorption of non-heme iron.
Physical or mental fatigue: two faces of the same problem
Physical fatigue
Heavy muscles, reduced athletic performance, slow recovery: it is often linked to deficiencies in iron, magnesium, and B vitamins. Zinc also contributes to normal carbohydrate, fat, and protein metabolism, which is essential for energy production.
Mental fatigue
Difficulty concentrating, irritability, and nervous exhaustion without physical exertion: chronic stress is often the main cause, aggravated by a lack of vitamins B6, B9, B12, and zinc. Vitamin B6 contributes to the normal functioning of the nervous system.
Rhodiola: the adaptogen for severe fatigue
Rhodiola (Rhodiola rosea) is an adaptogenic plant that has been used for centuries in the traditional medicines of Northern Europe and Asia. It helps the body better withstand stress and fatigue:
- By modulating the cortisol response
- By supporting cognitive functions under pressure
- By improving physical and mental endurance
Combined with spirulina - a microalga exceptionally rich in protein, iron, and antioxidants - it provides a solid foundation for combating chronic fatigue.
Acerola and maca: natural, long-lasting vitality
Acerola is one of the most concentrated sources of natural vitamin C. Unlike synthetic vitamin C, it provides a matrix of cofactors (bioflavonoids and polyphenols) that improve its bioavailability and antioxidant action.
Maca (Lepidium meyenii), a root from the Peruvian Andes, is known for its toning properties. Rich in essential amino acids, minerals, and macamides, it contributes to overall vitality and resistance to exertion.
How can you regain lasting energy?
Rather than looking for quick fixes (caffeine, sugar, stimulants), a sustainable approach involves:
- Identifying deficiencies: blood tests (iron, ferritin, vitamins B12 and D, erythrocyte magnesium)
- Improving dietary intake: legumes, whole grains, green vegetables, fruit, and high-quality animal proteins
- Supporting the body with targeted active ingredients: adaptogenic plants and essential micronutrients work at a deeper level
- Managing stress: stress-related adrenal fatigue is one of the most underestimated causes of persistent exhaustion
What those who have tried it say
In studies conducted by Lab'Epycure on the Multivitamin+ Course:
- 97% of participants report better physical and mental well-being
- 1 in 2 people feel less overwhelmed after just 30 days
With Energy Boost:
- 100% of testers feel more energetic
- 93% notice fewer energy slumps during the day
Epycure's approach to chronic fatigue
At Epycure, two complementary products address fatigue from every angle:
The Multivitamin+ Course provides a complete spectrum of micronutrients - B vitamins (B1, B2, B3, B5, B6, B9, B12), vitamin C, vitamin D3, zinc, selenium, iron, and magnesium - along with rhodiola and spirulina. Vitamin B3 helps reduce fatigue, vitamin B6 contributes to normal energy metabolism, and iron helps reduce fatigue.
Energy Boost complements this action with acerola (natural vitamin C with high bioavailability) and maca, for a deep revitalization of vitality. The two products can be combined for optimal synergy.
Directions for use: 2 capsules per day with a large glass of water, ideally in the morning. Visible results from 3 to 4 weeks.
