How do I know Solius is working?

Health outcomes can be tracked through objective measures such as vitamin D levels, DEXA scans, stool samples, blood pressure, and validated patient-reported assessments.

Solius Pro is FDA-cleared for stimulating vitamin D production, and the most reliable way to track your results is through a serum 25-OH vitamin D blood test. Take a baseline before you start, then retest at 8–12 weeks to see the impact. In a randomized controlled trial published in Anticancer Research, participants saw a significant average increase of about 10 ng/mL - a mean individual percent change of 76% from their baseline level.

Many users report improvements in mood and energy shortly after treatment, along with better sleep, focus, and overall wellbeing over time. Beyond vitamin D production, researchers continue to study how UVB exposure influences bone health, cardiovascular function, immune signaling, metabolism, and the gut microbiome. These emerging areas are supported by the broader scientific literature on sunlight and UVB exposure and are the focus of ongoing Solius research.

Consistent weekly Solius sessions help maintain the sunlight-driven processes our bodies rely on. Over time, this UVB light exposure may help address some of the physiological effects associated with insufficient sunlight exposure.
