  2. Ingredients

    Supplement Fact  Amount Per One Drop

    • Vitamin D3 (as cholecalciferol) 2000 IU

    Free from chemical excipients, artificial colourings, artificial flavors, artificial sweeteners, gluten, gmo's.

  3. Benefits

    Vitamin D3 helps maintain normal blood calcium levels and the normal condition of bones and teeth. In addition, vitamin D3 keeps blood calcium levels within normal limits, increasing its absorption from the gut and reducing its renal excretion.

    In this way vitamin D3 helps maintain bone mass and calcium-phosphorus homeostasis. According to European Regulation 432/2012, vitamin D3 contributes to the normal functioning of the immune system and the maintenance of normal muscle function.

  4. See the science

    Under normal circumstances, ten to twenty minutes of sun exposure, without sunscreen, is enough for the body to produce 10,000 to 20,000 IU. The use of sunscreen and soap does not allow vitamin D to be absorbed by the body.

    It is the most common deficiency among people all over the world. The type of vitamin D3 selected is provitamin 25 (OH) D3, the safest form of vitamin D, which is the type produced in the body by sun exposure and it is activated in the body only when needed.

  5. How to use

    Take one drop daily in a glass of water or juice or according to the directions of your practitioner. Do not exceed the recommended daily dose. Shake well before each use.
