Effects of Policosanol and Exercise on Fitness and Lipids in People With Elevated Blood Lipids

2026年7月15日 更新者:Songdhasn Chinapong、Mahidol University

Effect of Policosanol Supplementation Combined With Concurrent Exercise Training on Physical Fitness and Lipid Profiles in Healthy Volunteers With Elevated Blood Lipid But Not Required Medical Treatment

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.

詳細な説明

This clinical trial is designed to examine whether low-dose policosanol supplementation, alone or in combination with concurrent exercise training, can improve physical fitness, muscle recovery, inflammatory responses, and blood lipid profiles in adults with dyslipidemia who are not currently indicated for lipid-lowering medication.

Dyslipidemia is an important modifiable risk factor for cardiovascular disease. Lifestyle modification, including regular exercise, is commonly recommended for individuals with elevated blood lipids before pharmacological treatment is required. Policosanol, a mixture of long-chain aliphatic alcohols mainly derived from plant waxes, has been investigated for its potential effects on lipid metabolism, inflammation, oxidative stress, and exercise-related fatigue. The potential additive effect of combining low-dose policosanol with structured exercise training remains insufficiently established.

This study will compare the independent and combined effects of policosanol supplementation and concurrent exercise training over a 12-week intervention period. The exercise program is designed to integrate aerobic and resistance exercise components. Participants will be assessed at baseline and after the intervention period to determine changes in physical fitness, lipid-related outcomes, and selected biochemical markers related to inflammation and skeletal muscle function.

The study is expected to provide evidence on whether a low dose of policosanol that is regulatory-acceptable (Thai FDA) can be used as an adjunct to exercise training to support cardiometabolic health, physical fitness, and muscle recovery in adults with elevated blood lipid levels. Findings may contribute to future nutrition and exercise recommendations for adults with early-stage dyslipidemia who are not yet receiving lipid-lowering medication.
