Solius is an FDA-cleared over-the-counter (OTC) UVB light panel intended to stimulate production of vitamin D in people 22 years and older. The FDA regulates UVB devices intended for human use and requires them to undergo regulatory review. FDA clearance means the device's safety, performance, and labeling were reviewed by the FDA before it could be sold. UVB devices sold for human use without FDA clearance have not been reviewed for safety and may not be legally marketed. Learn why FDA clearance matters for UVB light therapy.

Solius is clinically proven to stimulate the production of vitamin D. References to the benefits of sunlight, UVB light, and vitamin D are based upon published, peer-reviewed research. The Solius device is not intended to diagnose, treat, cure, or prevent disease, except for the indications for use described in the user manual for your applicable region. Solius does not provide specific medical advice to users. Users should seek advice from a qualified physician or healthcare provider. This website does not establish a doctor-patient relationship.
