    Vitamin D plays a crucial role in our body's functioning. During the autumn-winter season, when sun exposure is limited, most people in Poland are deficient in this important vitamin.

    Why is vitamin D so important?

    • Supports the immune system
    • Regulates calcium-phosphate metabolism
    • Affects mood and cognitive functions
    • Reduces the risk of autoimmune diseases

    The recommended supplementation dose in Poland is 2000-4000 IU daily during autumn-winter, preferably in D3 form.
