Manufacturers of questionable vitamin D supplements have pulled their products from retail distribution, following findings by the University of Eastern Finland showing that many products fall short of the claims on their packaging.
The EU-based manufacturers of Force D 125 vitamin D and Mega D3 125 dietary supplements have withdrawn the products, following the study which suggested that the products contained no vitamin D at all.
Earlier on Thursday, Kristiina Vuori of the Yliopiston Apteekki pharmacy chain confirmed that orange-flavoured Sana Sol vitamin D tablet supplements were also removed from circulation.
The university study showed that the vitamin content was below the recommended daily allowance.
The food safety agency Evira is to re-test some of the questionable products.
Residents of countries with long winter darkness, such as Finland, are strongly recommended to take vitamin D supplements.
