RecruitingDietary supplementA Study to Evaluate the Impact of a Magnolia Officinalis Dietary Supplement on Immune Biomarkers in Subjects With PsoriasisThe goal of this clinical trial is to evaluate whether Viv, a consumer-grade dietary supplement derived from the Magnolia officinalis plant, has an effect on biomarkers of immune activity in adults with psoriasis. To address this question, this trial will compare Viv to a placebo (a look-alike substance that contains no drug). Participants will: * Take Viv or a placebo every day for 3 months. * Complete electronic questionnaires about their quality of life and psoriasis symptoms at the beginning of the study and again at 1 months and 3 months. * Be provided with at home blood collection kits, which they will use to collect blood at the beginning of the study and again at 1 months and 3 months. Researchers will analyze these blood samples to measure the levels of specific inflammatory proteins and evaluate how they change over the course of the study in the participants taking Viv compared to those taking placebo.
