POSSIBLY INEFFECTIVE

• Hypercholesterolemia. Oral hesperidin does not seem to reduce cholesterol levels. Details: Clinical studies and a meta-analysis of the available clinical research show that taking hesperidin 400-800 mg daily for 4-12 weeks does not affect total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, or triglyceride levels when compared with placebo in healthy and obese individuals with or without mild hypercholesterolemia (94539,102315). However, some preliminary clinical research shows that taking glucosyl hesperidin, a soluble hesperidin derivative, 500 mg daily for 24 weeks modestly lowers serum levels of triglycerides and LDL cholesterol when compared with baseline in patients with both hypercholesterolemia and hypertriglyceridemia, but not in those without hypertriglyceridemia (54800). The validity of this finding is limited by the lack of a comparator group.
• Obesity. Oral hesperidin does not seem to be beneficial for weight loss. Details: A meta-analysis of two clinical trials shows that taking hesperidin for 6-12 weeks does not affect body weight or body mass index (BMI) when compared with placebo, although it may modestly improve waist circumference (105280,105281). The studies included in this analysis were short-term and were not designed to evaluate weight as a primary endpoint. Other clinical research conducted in Japan shows that taking glucosyl hesperidin, a soluble hesperidin derivative, 470 mg orally daily for 12 weeks does not reduce body weight, total fat area, or subcutaneous fat area when compared to baseline in modestly overweight patients (94544). Hesperidin has also been evaluated in combination with green tea extract. One clinical study in overweight individuals shows that taking a combination of glucosyl hesperidin 178 mg and green tea extract, providing epigallocatechin gallate (EGCG) 146 mg, daily for 12 weeks modestly attenuates an increase in weight and BMI when compared with placebo. Sub-group analyses suggest that the greatest effects occurred in individuals less than 50 years of age (108152). It is unclear if these effects are due to hesperidin, green tea extract, or the combination.

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Athletic performance. It is unclear if oral hesperidin is beneficial for improving athletic performance. Details: Small clinical studies in healthy male cyclists show that taking a specific form of hesperidin (Cardiose, HealthTech BioActives) has some benefit on athletic performance. One study shows that taking this form of hesperidin 500 mg once, five hours prior to exercise, improves average power, maximum speed, and total energy when compared with placebo. However, it does not improve peak power, time to peak power, or total oxygen consumption (102312). Taking this form of hesperidin 500 mg daily for 8 weeks modestly improves the highest average power output that can be maintained for one hour and the maximal power during an incremental test when compared with placebo. However, there was no effect on the aerobic or anaerobic ventilatory thresholds, oxygen use, or the times to peak power or maximum speed when compared with placebo (105277).
• Chronic prostatitis and chronic pelvic pain syndrome (CP/CPPS). Although there is interest in using oral hesperidin for CP/CPPS, there is insufficient reliable information about the clinical effects of hesperidin for this condition. There is research evaluating the use of micronized purified flavonoid fraction, which contains small amounts of hesperidin. See Diosmin for more information.
• Chronic venous insufficiency (CVI). Oral hesperidin has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research shows that taking a specific combination product containing hesperidin methyl chalcone 150 mg, butcher's broom root extract 150 mg, and ascorbic acid 100 mg (Cyclo 3 Fort) usually for 1-3 months may decrease pain, heaviness, cramps, and paresthesia in patients with CVI (37483). There is also research evaluating the use of micronized purified flavonoid fraction, which contains small amounts of hesperidin, for CVI. See Diosmin for more information.
• Cognitive function. Although there is interest in using oral hesperidin for improving cognitive function, there is insufficient reliable information about the clinical effects of hesperidin for this condition.
• Coronary artery bypass graft (CABG) surgery. Although there is interest in using oral hesperidin for patients undergoing CABG surgery, there is insufficient reliable information about the clinical effects of hesperidin for this purpose. There is research evaluating the use of micronized purified flavonoid fraction, which contains small amounts of hesperidin. See Diosmin for more information.
• Diabetes. It is unclear if oral hesperidin is beneficial for diabetes. Details: Clinical research in adults with diabetes shows that taking hesperidin (Swanson Health Products) 500 mg once daily for 6 weeks reduces systolic blood pressure and the mean arterial blood pressure by about 3% and 2.5%, respectively, when compared with placebo. Although this improvement is statistically significant, it is unlikely to be considered clinically significant. Also, hesperidin does not modify levels of fasting blood glucose or measures of insulin resistance (98697,105292). A prospective observational study in patients with type 1 or type 2 diabetes has found that taking a specific product (Flebotrofine, AMNOL Chimica Biologica) containing hesperidin for 3 months is not associated with improvements in HbA1c, cholesterol, or triglyceride levels when compared with baseline. Other ingredients in this product included L-arginine, troxerutin, diosmin, black currant extract, and gotu kola extract (108151). There is also research evaluating the use of micronized purified flavonoid fraction, which contains small amounts of hesperidin, for diabetes. See Diosmin for more information.
• Diabetic retinopathy. Although there is interest in using oral hesperidin for diabetic retinopathy, there is insufficient reliable information about the clinical effects of hesperidin for this condition.
• Hemorrhoids. Oral hesperidin has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in patients with acute hemorrhoidal crisis shows that taking a specific supplement (Triade H, Omikron Italia Srl) containing hesperidin, diosmin, and troxerutin daily for 43 days results in significantly less pain, bleeding, anal itching, and medication use when compared with placebo (93885). This product was given as one sachet of powdered diosmin 300 mg, troxerutin 300 mg, hesperidin 300 mg, and vitamin C 12 mg mixed in water orally three times daily for 3 days, then two sachets daily for 2 days, then one sachet daily for seven days, followed by one tablet containing hesperidin 100 mg, diosmin 300 mg, and troxerutin 300 mg daily for one month (93885). There is also research evaluating the use of micronized purified flavonoid fraction, which contains small amounts of hesperidin, for hemorrhoids. See Diosmin for more information.
• Hypertension. It is unclear if oral hesperidin is beneficial for hypertension. Details: Preliminary clinical research in overweight males with or without hypertension shows that taking hesperidin 136 mg or drinking 250 mL of orange juice containing hesperidin 136 mg twice daily for 4 weeks lowers diastolic, but not systolic, blood pressure by around 5 mmHg when compared with placebo (94543). However, a meta-analysis of the available clinical research shows that taking hesperidin supplements 400-800 mg daily for 4-12 weeks does not reduce systolic or diastolic blood pressure when compared with placebo in healthy and obese individuals with or without hypertension (102315). Due to the mixed populations evaluated in this research, the effect of hesperidin in patients with diagnosed hypertension is unclear.
• Hypertriglyceridemia. It is unclear if oral hesperidin is beneficial for hypertriglyceridemia. Details: Preliminary clinical research in patients with hypercholesterolemia shows that taking glucosyl hesperidin, a soluble hesperidin derivative, 500 mg daily for 6 weeks modestly lowers triglyceride levels when compared with baseline in patients who also have hypertriglyceridemia, but not in those without hypertriglyceridemia. However, glucosyl hesperidin did not lower cholesterol levels; a lower dose of 100 mg daily had no effect on either outcome (105290). Clinical research in a similar population shows that taking glucosyl hesperidin 500 mg daily for 24 weeks reduces triglyceride levels by up to 34% from baseline and modestly reduces levels of low-density lipoprotein cholesterol (54800). The validity of the findings in these studies is limited by the lack of a comparator group.
• Lymphedema. Oral hesperidin has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research in females with lymphedema due to breast cancer surgery shows that taking three capsules of a specific combination product (Cyclo 3 Fort), which contains hesperidin methyl chalcone 150 mg, butcher's broom root extract 150 mg, and ascorbic acid 100 mg per capsule, three times daily orally for 90 days reduces swelling in the upper arm and forearm and improves mobility and heaviness when compared with placebo (37494). There is also research evaluating the use of micronized purified flavonoid fraction, which contains small amounts of hesperidin, for lymphedema. See Diosmin for more information.
• Metabolic syndrome. It is unclear if oral hesperidin is beneficial for metabolic syndrome. Details: A small clinical study in adults with metabolic syndrome shows that taking hesperidin (Shaanxi Yuantai Biological Technology Co., Ltd) 500 mg twice daily for 12 weeks increases the number of patients who no longer have defined metabolic syndrome by almost two-fold when compared with placebo. There were also modest reductions in fasting blood glucose, triglycerides, and systolic blood pressure, as well as the total number of patients with abdominal obesity, elevated blood pressure, and elevated fasting blood sugar. However, there were no differences in levels of high-density lipoprotein (HDL) cholesterol, diastolic blood pressure, or waist circumference (105288). In another preliminary clinical study using the same product, there were modest reductions in systolic blood pressure and triglyceride levels when compared with no treatment. However, there were no effects on other measures of metabolic syndrome or the overall number of patients with defined metabolic syndrome. When taken in combination with flaxseed 15 grams twice daily, serum concentrations of triglycerides and glucose, as well as systolic blood pressure, were modestly improved when compared with control. The prevalence of individuals with defined metabolic syndrome at the end of treatment was reduced by approximately 77%, which was significant when compared with the control group (105276). These studies may have been too small to detect differences in most endpoints.
• Minor bleeding. Although there is interest in using oral hesperidin for minor bleeding, there is insufficient reliable information about the clinical effects of hesperidin for this purpose. There is research evaluating the use of micronized purified flavonoid fraction, which contains small amounts of hesperidin. See Diosmin for more information.
• Nonalcoholic fatty liver disease (NAFLD). It is unclear if oral hesperidin is beneficial for NAFLD; the available evidence is conflicting. Details: A small clinical trial in adults with NAFLD shows that taking hesperidin 1 gram daily for 12 weeks along with lifestyle modification improves hepatic steatosis as measured by transient elastography when compared with placebo and lifestyle modification. Taking hesperidin also modestly improves total cholesterol, triglyceride, alanine aminotransferase (ALT), and gamma-glutamyl transferase (GGT) levels. However, there were no effects on liver fibrosis or levels of aspartate aminotransferase (AST), fasting blood glucose, insulin, low-density lipoprotein (LDL) cholesterol, or high-density lipoprotein (HDL) cholesterol (102313). Other preliminary clinical research using the same treatment protocol shows that although there were modest reductions in ALT, there was no effect on liver steatosis, liver fibrosis, or other metabolic measures. When used in combination with flaxseed 30 grams daily, levels of fasting blood glucose and a measure of insulin resistance were modestly improved (105275). These studies may have been too small to detect differences in most endpoints.
• Rheumatoid arthritis (RA). It is unclear if oral hesperidin is beneficial for RA. Details: A small clinical study shows that drinking a 100 mL beverage containing alpha-glucosyl hesperidin 3 grams daily orally for 12 weeks might improve symptoms of RA when compared with placebo (54850).
• Varicose veins. Although there is interest in using oral hesperidin for varicose veins, there is insufficient reliable information about the clinical effects of hesperidin for this condition. There is research evaluating the use of micronized purified flavonoid fraction, which contains small amounts of hesperidin, for this purpose. See Diosmin for more information.
• Venous leg ulcers. Although there is interest in using oral hesperidin for venous leg ulcers, there is insufficient reliable information about the clinical effects of hesperidin for this condition. There is research evaluating the use of micronized purified flavonoid fraction, which contains small amounts of hesperidin, for this purpose. See Diosmin for more information. More evidence is needed to rate hesperidin for these uses.
