Key points from article :
Each year in the UK we spend around £442m on vitamins and supplements.
By law, supplements can contain 50% more or 20% less vitamin than listed on the label.
Products from Vitabiotics, Holland & Barrett and Nature’s Best fell outside of these parameters.
E.g. Holland & Barrett ABC Plus multivitamins contained half of the vitamin A listed.
Manufacturers dispute the results.
Companies also used unauthorised and exaggerated claims on their websites.
