Clinical trials

This study will be a randomized, double-blind, placebo-controlled trial. It will be conducted over a 8-week intervention investigating the effects of creatine (5g Creatine monohydrate); placebo control (5g resistant dextrin), and a combination group containing both creatine and tyrosol (5g creatine monohydrate + 150mg tyrosol/day). Endurance, strength, cognition, and fatigue resistance will be examined through repeated strength and endurance testing (described below). Participants who pass initial screening will be invited on-site for day one (Visit 1) of testing where the participants will proceed with a series of tests which will include the following: (1) body composition; (2) mood and cognitive testing; (3) full-body strength testing; (4) 5RM (repetition maximum) bench press, leading to multiple sets of bench press (based on the previous weight) completed to failure; (5) finally, a time to exhaustion endurance test will be conducted followed by (6) repeat cognitive testing. After the 8-week supplementation period (\~56-60 days), all original measures will be repeated as before in the same order (Visit 2). Approximately 24 hours later (Visit 3) participants will complete a questionnaire for muscle soreness remotely, and again at 48 hours post-Visit 2 (visit 4).

The goal of this clinical trial is to learn if Quercefit® or Ubiqsome™ can improve markers of healthy aging, blood sugar control, and heart health in older adults. It will also learn about the safety of these supplements. The main questions it aims to answer are: 1. Do Quercefit® or Ubiqsome™ improve blood sugar, cholesterol, and markers of aging compared to a placebo? 2. What side effects, if any, do participants have while taking these supplements? Researchers will compare Quercefit® (500 mg/day), Ubiqsome™ (300 mg/day), and a placebo (a look-alike capsule with no active ingredient). Participants will: 1. Take their assigned capsules (Quercefit®, Ubiqsome™, or placebo) twice daily for 12 weeks 2. Go to a preferred clinic at the start and end of the study for a fasting blood draw Complete at-home tests: 3. Grip strength testing (using a device mailed to them) 4. Online surveys about fatigue and quality of life 5. Report any side effects and keep track of supplement use
