These cases are manifested by hypercalcemia (excessive calcium levels in the blood) which can have serious consequences, such as kidney damage due to the deposition of calcium in the kidney, she points out.
To prevent this risk
", the health authority asks "
health professionals and parents to give priority to drugs
" (Adrigyl, Deltius or ZymaD) "
over food supplements
", to "
control the doses administered
" by checking the number of drops swallowed, and "
do not multiply products containing vitamin D
Indeed, food supplements, sometimes preferred because of the preservatives or essential oils that the drugs can contain, can present particularly high dosages of vitamin D (up to 10,000 international units - or IU - per drop) and the "
' for their ingredients and their manufacture is less than for drugs.
Vitamin D supplementation is recommended in France "
from the first days of life
" and "
throughout the phase of growth and bone mineralization, that is to say up to 18 years
