There were no warnings on or in the packaging detailing the specific risks or side effects of taking Vitamin D supplements.
Coroner’s concerns
(1) Vitamin supplements can have potentially very serious risks and side effects when taken in excess
(2) Current food labelling requirements do not require these risks and side effects to be written on the packaging.
(3) Absence of appropriate warnings and guidance about dosage
