It has 20% of the rda of vit D - it's also the sunshine vitamin so unless you are in a blacked out room try get out in the sun, be it your balcony, back garden or just opening a window in a sunny room https://www.activia.us.com/probiotic-yogurt/activia-fruit/vanilla
ducksie, I think Vit D's been recommended for those who can't get out much. We're having nice weather but a lot of people don't have gardens or balconies.
Vitamin D is one of the few dietary supplements that the NHS recommends that everyone should take during the winter months, with sunlight normally providing us with enough for the rest of the year.
I understand that jno and was not trying to minimilise the question by saying get out .. I do understand not everyone has is living in a sunshine trap and needs there Vit d however they can get it in to them
