Randomized Controlled Trial Clinical Trial
Cholesterol-lowering effects of psyllium hydrophilic mucilloid for hypercholesterolemic men.
The effect of psyllium hydrophilic mucilloid on serum cholesterol levels was investigated in 26 men with mild to moderate hypercholesterolemia (range of cholesterol level, 4.86 to 8.12 mmol/L [188 to 314 mg/dL]) in a double-blind, placebo-controlled parallel study. Following a two-week baseline period, subjects were treated for eight weeks with 3.4 g of psyllium or cellulose placebo at mealtimes (three doses per day). All subjects maintained their usual diets, which provided less than 300 mg of cholesterol per day and approximately 20% of energy from protein, 40% from carbohydrate, and 40% from fat. ⋯ No significant changes in serum lipid levels, body weight, blood pressure, or other serum parameters were observed with placebo treatment. Subject adherence to psyllium treatment was excellent, and no adverse effects were observed. Results of this study show that psyllium is an effective and well-tolerated therapy for mild to moderate hypercholesterolemia.
