A Randomized, Placebo-Controlled, Double-Blind, Parallel-Group Pilot Trial Investigating the Impact of a Glycation Lowering (GLYLO) Supplement on Geroscience Outcomes in Postmenopausal Women
Buck Institute for Research on Aging
Summary
The aim of this study is to assess the effectiveness of GLYLO, a dietary supplement, in postmenopausal women aged 45 to 65 who are overweight or obese and have elevated HbA1c levels. Specifically, the study seeks to evaluate whether GLYLO can reduce advanced glycation end products (AGEs) levels, which are harmful compounds formed when sugar attaches to proteins or fats in the body and can contribute to aging and disease. The primary outcome of the study is to determine if GLYLO reduces AGEs, enhances metabolic and hormonal health, and mitigates age-related functional decline. This study includes one screening visit and three testing visits over a 6-month period. After eligibility is confirmed, participants will be randomly assigned to one of two groups to take either GLYLO (two capsules daily) or a placebo at home for 24 weeks. Participants will provide blood samples at every visit. During the three testing visits, they will complete physical performance and cognitive function tests, provide both blood and urine samples, and fill out quality of life and 24-hour dietary intake questionnaires. The dietary intake questionnaires will be completed only twice i.e. at the baseline visit and again at the final 6-month visit.
Description
Telephone Screening: Subjects are screened for eligibility by telephone for major exclusion criteria. They then attend a screening visit. Eligible participants will receive an Informed Consent Form to review prior to the in-person screening visit. Pre-Visit Requirements for all Visits: Fasting (water only) ≥10 hours, no alcohol, exercise, or cannabis products ≥10 hours. Visit 1: Screening Visit Upon arrival, participants will provide written consent before study procedures. A fasting blood sample will be collected for blood chemistry, hematology, lipid profile, HbA1c, and thyroid panel anal…
