MediSun Technology
Healthy Sun™

Our Leadership

MediSun Technology™ was founded in 2010 by a father-daughter team, Larry Spatz, his daughter Adora Spatz Sauer, and Barry Jay Riskin, M.D., who became interested in vitamin D and it's dramatic medical benefits. After studying the growing body of research on vitamin D and the challenges of getting sufficient vitamin D directly from the sun, the group began researching methods of vitamin D delivery, and found that phototherapy may be the most effective delivery system to optimize vitamin D.

In conjunction with a world class medical device engineering firm, Livingston Products Inc., they developed an entirely new, revolutionary UVB only phototherapy treatment system, the MediSun. The MediSun is designed to deliver medically supervised treatment for vitamin D deficiency. It is a breakthrough technology that increases users’ levels of vitamin D, enhances athletic performance, reduces pain, and boosts immunity.
