Ferrol Multivitamins with Iron in the larger 500ml bottle is a Caribbean liquid multivitamin tonic that has been a trusted household supplement across the diaspora for generations — the kind of tonic many Caribbean adults remember being given by the spoonful as children. The 500ml size is the family bottle, suiting households that take Ferrol regularly. Take by the spoon as directed on the label; particularly suitable for children or anyone who prefers a liquid format. As with any supplement, use as part of a balanced diet alongside medical advice rather than as a substitute. Ferrol is a long-established Caribbean tonic brand.
