Dear Client

At Sfera Bio Nutrition we are implementing some changes, which we would like to share with you. We are making label improvements and updates and are switching over to gold-coloured child-proof lids. These changes have been phased in over the last year and you may still encounter some of our stock with black lids, and previous label versions that are still in circulation during this time.

If you have any questions, please do not hesitate to contact us.
