The formula contains a coherent set of vitamins with benefits documented by scientific literature.

• Vitamin C (56 mg) : Essential for strengthening immunity, it also acts on collagen production and skin radiance. Numerous studies, notably published in Nutrients, confirm its role in defense against infections and oxidative stress.

• Vitamin E (4 mg) : A major fat-soluble antioxidant, it protects cell membranes from free radicals. Its effectiveness has been demonstrated in preventing cellular aging and reducing infections in the elderly.

• Vitamin B3 (Niacin – 8 mg) : It plays a central role in energy production and fatigue reduction. Studies have also suggested its interest in lipid metabolism and cognitive function.

• Vitamin B5 (Pantothenic Acid – 4.5 mg) : Essential for the synthesis of coenzyme A, it supports energy production, concentration and resistance to stress.

• Vitamin B6 (0.9 mg) : It promotes hormonal balance, participates in the synthesis of neurotransmitters (dopamine, serotonin, GABA) and improves the metabolism of amino acids.

• Vitamin B2 (Riboflavin – 0.6 mg) : This vitamin supports both vision and the transformation of nutrients into energy, while having an antioxidant role.

• Vitamin B1 (Thiamin – 0.6 mg) : It stimulates memory and the proper functioning of the central nervous system, by intervening in neuronal carbohydrate metabolism.

• Vitamin A (0.4 mg) : Essential for vision, immunity, and cell renewal. It also helps maintain healthy, glowing skin.

• Vitamin B9 (Folic Acid – 160 µg) : Essential for cell regeneration, DNA production and prevention of neural tube defects during pregnancy.

• Vitamin B8 (Biotin – 40 µg) : Known as “the beauty vitamin,” it strengthens hair and nails, and also plays a role in macronutrient metabolism.

• Vitamin B12 (0.1 µg) : Crucial for the proper functioning of the nervous system, the formation of red blood cells and the reduction of fatigue. Even at very low doses, it is beneficial when properly absorbed.

• Dicalcium phosphate (100 mg) : Source of calcium and phosphorus, two minerals essential for bone strength and muscle contraction.

• Magnesium (100 mg as hydroxide) : Known for its anti-stress effect, it promotes relaxation, muscle recovery and helps reduce fatigue. Mild deficiency is common in the general population.

• Zinc (25 mg in gluconate form) : A powerful immune stimulant, it promotes healing and helps regulate sebum production, hence its effectiveness on skin problems (acne, dermatitis).

• Potassium (80 mg in gluconate form) : Mineral essential for water balance and good muscle function, it also helps regulate blood pressure.

• Iodine (90 µg as potassium iodide) : Essential for the synthesis of thyroid hormones, it plays a crucial role in energy metabolism and hormonal regulation.

• Selenium (15 µg in the form of enriched yeast) : A key antioxidant, it supports immunity and protects cells against oxidative damage. It is also involved in male fertility and thyroid function.
