Reserve your spot in The SOLSTICE Study

We are excited to announce our current research study, the SOLSTICE Study! If you'd like to reserve a spot, click the link below to book your initial appointment. You can find study requirements and details below.


The SOLSTICE Study will last 3 months. Participants will be asked to use SOLIUS 3 times per month. We are evaluating the ability of SOLIUS to replace oral vitamin D supplements therefore, all subjects will be required to stop taking vitamin D supplements for the duration of the study. Enrollment is limited to those 18 years of age and older. Enrolled participants are expected to pay $150 by the end of the study to help offset costs. Waivers are available for participants in financial need. There will be two (2) finger-prick blood tests measuring biomarkers of vitamin D in the blood: an initial baseline test and again after three months. The initial appointment will last about 45 minutes, consisting of screening to determine eligibility for participation, paperwork, the baseline finger-prick blood test, account setup, and the first SOLIUS session. Remaining treatment appointments should take no longer than 10 minutes from start to finish, and you will have the flexibility to come in at any time during open hours of the study.
