About us

Who are we? 

Founded in 2010 Internis is a pharmaceutical company engaged in the development of highly effective and innovative prescription medicines aimed at the prevention and treatment of common bone disorders such as osteoporosis and Vitamin D deficiency. Internis is the leading manufacturer and supplier of prescription Vitamin D medicines (not food supplements) for the UK market.

Therapeutic Focus 

Internis is fully committed to safeguarding the bone health of patients and believes strongly that this can only be achieved through the intervention of qualified medical practitioners and the appropriate use of prescription medicines, not food supplements.


Prescription Medicines 

This website has been developed by Internis as a resource for Healthcare Professionals, patients and for members of the public interested in Vitamin D and bone health.  The objective of this website is to provide helpful, accurate and up to date information and resources concerning all aspects of bone health and Vitamin D. In particular the website aims to draw attention to the potentially serious health consequences of Vitamin D deficiency and the importance of using prescription medicines, not food supplements, to treat the condition.

Current work

Internis launched its proprietary product Accrete D3 (calcium/colecalciferol tablets) in to the UK market during 2011.  This was closely followed by the launch of Fultium D3 800IU (colecalciferol equivalent to 20 micrograms Vitamin D3) in 2012 and Fultium D3 3,200IU (colecalciferol equivalent to 80 micrograms Vitamin D3) in 2014.

Internis are currently working on extensions to the Fultium D3 range which will give doctors new therapy options and which ultimately will extend therapy benefits to new patient groups.
