Vitamin C+ Study 2

Vitamin C+ Study 2

We are seeking approximately 152 participants to take part in a 28-day randomized, double-blind, placebo-controlled study evaluating the effects of Qualia Vitamin C+, a dietary supplement designed to support vitamin C levels and overall well-being in healthy adults aged 25 to 75 years. Participants will be randomly assigned to receive one of two study products: Qualia Vitamin C+ or a placebo. Each participant will take 2 capsules once daily in the morning, with or without food, for 28 days.

This is a biomarker study that will require two blood draws conducted through Ulta Labs, one at the start of the study and one at the end. Both blood draws must be completed following an overnight fast, and all blood draws will be paid for by Qualia Life Sciences. Eligibility is determined in part by the results of the first blood test. The study will also include self-report questionnaires assessing health-related quality of life, fatigue, immune fitness, and safety and tolerability from the start to the end of the study.

Upon completion of all study requirements, participants will receive up to $300 in credit at Qualia Life Sciences as a thank-you for their time and participation.
