Is this trial a fit for you?

Likely a good fit

Women aged 40–65 with overweight or obesity (BMI >25 kg/m2) who are not pregnant or breastfeeding and are not using weight-loss, diabetes, or lipid-lowering medications are ideal candidates.

Probably not a fit

Men, people with BMI under 25, individuals with diabetes, recent bariatric surgery, major chronic kidney, liver, autoimmune disease or cancer, current alcohol addiction, recent sirtuin activator use, or those who are pregnant or breastfeeding are unlikely to benefit or may be ineligible.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Women aged 40–65 with BMI over 25 will take either a sirtuin activator supplement or a placebo each day for six months. Researchers will compare the two groups on lipid and carbohydrate metabolism as well as measures of oxidative stress, immune function, and cellular ageing. Participants will visit the university every three months for checkups and laboratory tests. The study compares outcomes between the supplement and placebo arms to determine whether the supplement produces measurable metabolic improvements.

Why it matters

Potential benefit: If effective, the supplement could improve lipid and glucose metabolism and reduce oxidative stress in middle-aged women with excess weight.

How similar studies have gone: Small human studies of sirtuin activators have reported mixed metabolic effects, so the approach is promising but not yet proven in larger trials.
