Vitamin D3: Internal balance to enhance your daily life


Vitamin D3 (cholecalciferol) is an essential vitamin naturally synthesized by the body through sun exposure. It plays a key role in the body's overall balance, particularly in the immune and muscular systems, and in energy production.


During periods of seasonal fatigue, lack of light exposure or decreased vitality, an appropriate intake of vitamin D3 helps to maintain optimal physiological function.


It contributes in particular to:

  • ☀️ To the normal functioning of the immune system

  • 💪 To normal muscle function

  • 🧠 To maintain a general balance

  • ⚖️ To maintain normal bone structure


A supported and balanced body is better able to recover effectively.

Incorporated into an evening formula, vitamin D3 contributes to a holistic approach to well-being, supporting the fundamental mechanisms linked to vitality and physiological stability.

Vitamin D3: scientific data and physiological role


Vitamin D3 (cholecalciferol) is a fat-soluble vitamin involved in many biological processes.

🧬 1. Role in immunity


Vitamin D contributes to the normal function of the immune system.


Vitamin D receptors (VDRs) are present in various immune cells, indicating its involvement in regulating the immune response.

Regulation (EU) No 432/2012.

💪 2. Muscle function and recovery


Vitamin D contributes to normal muscle function.


VDR receptors are also present in muscle tissue, suggesting a role in muscle contraction and performance.

⚡ 3. Vitality and general balance


Adequate vitamin D status is associated with maintaining:

  • From a normal mineral metabolism

  • From an overall physiological balance

  • For optimal cellular function


It plays a role in the regulation of calcium and phosphorus.

📌 Claims permitted in Europe


Vitamin D contributes to:

  • to the normal functioning of the immune system

  • to the maintenance of normal muscle function

  • to the maintenance of a normal skeletal structure

  • to normal absorption/utilization of calcium and phosphorus
