This study will evaluate the effects of policosanol supplementation, concurrent exercise training, and their combination on physical fitness, muscle recovery, inflammatory markers, and blood lipid profiles in adults with elevated blood lipids who are not currently indicated for lipid-lowering medication.
Participants will be randomly assigned to one of four groups for 12 weeks: policosanol plus exercise training, policosanol alone, placebo plus exercise training, or placebo without structured exercise training. Participants assigned to the supplementation groups will take policosanol 5 mg per day, while those assigned to the placebo groups will take a matching placebo. Participants assigned to the exercise groups will complete a standardized concurrent exercise training program combining aerobic and resistance exercise.
The study will compare changes in physical fitness, lipid profiles, and selected blood biomarkers before and after the intervention. The findings may help determine whether low-dose policosanol, alone or combined with exercise training, can support cardiometabolic health and physical fitness in adults with dyslipidemia.
Men and women aged 25 to 59 years.
BMI between 18.5 and 29.9 kg/m².
Total cholesterol ≥ 200 mg/dL;
Low-density lipoprotein cholesterol ≥ 130 mg/dL and < 190 mg/dL;
Current or recent use within the past 3 months of lipid-lowering medications or dietary supplements known to influence lipid metabolism, including statins, fibrates, niacin, omega-3 fatty acids, red yeast rice, or policosanol.
Known allergy or hypersensitivity to policosanol, sugarcane derivatives, capsule components, or any excipients in the supplement formulation.
Presence of chronic or comorbid conditions that may make exercise participation unsafe, including but not limited to cardiovascular disease, chronic obstructive pulmonary disease, severe arthritis, osteoporosis, uncontrolled diabetes, gastrointestinal disorders, or neurological impairments affecting movement control.
High-risk lifestyle factors, including heavy smoking, excessive alcohol consumption, or use of recreational drugs.
