SOLIUS was designed to emit light within the specific vitamin D action spectrum while eliminating nearly all other UV light.

“Vitamin D is used to improve bone health and decrease fractures. Vitamin D may also protect against osteoporosis, high blood pressure, cancer, and other diseases.”

Mayo Clinic

Vitamin D functionality is implicated in over 200 physiologically regulated processes, ranging from modulation of gene expression to activation of protein receptors and signaling pathways.

Vitamin D plays a key role in the homeostasis of calcium and phosphate in the body, helping with mineralization of bone and proper functioning of the musculature. However, its impact goes much deeper.

When levels of Vitamin D are deficient in the body, systems suffer and perform sub-optimally. This manifests as a hormonally dysregulated system, with increased risk for bone demineralization, reduced ability to fight infection, and increased likelihood of complication from autoimmune diseases such as rheumatoid arthritis, Crohn’s disease, irritable bowel syndrome, and type 1 diabetes, among others.


“Vitamin D deficiency is a global pandemic that has serious health consequences for children and adults. Improvement in the world’s vitamin D status could significantly reduce risk of many chronic illnesses including cardiovascular diseases, type II diabetes and many deadly cancers as well as infectious diseases including upper respiratory tract infections, influenza and tuberculosis.”

Our research shows that the amount of ultraviolet energy delivered by SOLIUS is significantly lower than any other vitamin D producing light source. A single SOLIUS treatment is expected to produce 10 times more vitamin D than 19 minutes of midday summer sunlight, yet the total amount of UVR administered is equivalent to, on average, only 9 seconds in the sun.

Our Advisory Board
