The colorants used in the new Feramax® capsules are approved by Health Canada and US FDA. The new colours have been derived by changing the proportions of the current colours, and the addition of a new colorant from the same family. D&C Red #28 has been replaced with D&C Red #33 and a new colorant FD&C yellow #6 has been added. All the colours have been tested rigorously to ensure that they are gluten free, and do not change any quality parameters including shelf life, compared to the former capsules. The product continues to be released for use as per the same exacting standards.
