Please note, as from the 1st September 2018 – new labels will be introduced across the Orthoplex brands. Because this is a gradual process, the design and logo on the label of the featured bottle image may differ from the product bottle purchased as we transition to our new look labels. The product, its quality, ingredients, indications, storage and warnings remain exactly the same.
