  • Culture Enzymes Minerals & Vitamins

Vitamin D3, known as the "sunshine vitamin," is produced by our skin when exposed to sunlight. Its levels can decrease during winter, contributing to a higher prevalence of deficiency during those months.

Vitamin D3, recognized by the EFSA, is essential for various health aspects. It supports normal bone health by aiding calcium and phosphorus absorption, preventing conditions like rickets and osteomalacia. It also contributes to immune system function, regulating immune responses and preventing excessive inflammation. Adequate vitamin D levels are crucial for normal muscle function and reducing the risk of falls, particularly in older individuals. Additionally, vitamin D plays a role in cell division, supporting growth and development in tissues and organs. It enhances calcium and phosphorus absorption, promoting their incorporation into bone tissue and helps regulate blood calcium levels by reducing excretion.
