vitamin D?
Vitamin D is a contributes to the maintenance of normal bones and contributes to the normal function of the immune system. The primary source of vitamin D3, or cholecalciferol, is the sun, whose rays allow the skin to synthesize vitamin D, though it is also present in certain foods.
Exposure to sunlight is not always possible (especially in winter and autumn) and the amount of vitamin D found in food could not be sufficient. In these cases of low levels of vitamin D the use of food supplements could be helpful, such as Vitamin D3 IBSA food supplement in orodispersible films.

When could low levels of vitamin D occur?
Pre-menopause/menopause
The drop in estrogen levels associated with menopause can lead to a loss of bone mass. That’s why a vitamin D supplement may help, as it contributes to the maintenance of normal bones.
Intense physical activity
For individuals who participate in intense physical activity, Vitamin D supplementation may be helpful. Vitamin D contributes to the maintenance of normal bones and also contributes to the maintenance of normal muscle function, supporting overall musculoskeletal health.
In old age
It is very common for seniors to have low vitamin D levels. This is because they tend to stay indoors or avoid sunshine. Moreover, in the elderly, the skin produces less vitamin D when exposed to the sun as compared to younger people.

Food supplements should not be used as a substitute for a varied diet and a healthy lifestyle.
