• Benign prostatic hyperplasia (BPH). Oral beta-sitosterol is beneficial for most symptoms of BPH. Details: Taking beta-sitosterol 60-130 mg orally in 2-3 divided doses daily for up to 18 months significantly improves urinary symptoms, increases maximum urinary flow, and decreases postvoid residual urine volume; however, it does not affect prostate size (5327,5328,5329,7195,7198,34975). Additionally, one study suggests that taking an enriched form of saw palmetto oil (Vispo) 200 mg containing 3% beta-sitosterol twice daily for 12 weeks seems to be more effective than standard saw palmetto oil containing 0.3% beta-sitosterol for reducing some measures of overall symptoms of BPH (104803). Although some preliminary research shows no benefit of beta-sitosterol on symptoms of BPH, the variability in doses used, the short duration of treatment, the small study sizes, and the differing severity of disease at baseline limit the reliability of these latter results (35124,96784).
• Hypercholesterolemia. Oral beta-sitosterol is beneficial for hypercholesterolemia. Details: Taking beta-sitosterol orally significantly reduces total and low-density lipoprotein (LDL) cholesterol levels, but has little or no effect on high-density lipoprotein (HDL) cholesterol levels. Beta-sitosterol 0.65-1.5 grams twice daily has been used, typically in conjunction with a low-fat diet (6668,7195,112081). The effects of combination formulations containing beta-sitosterol have also been evaluated in patients with hypercholesterolemia. Some preliminary clinical research in these patients shows that taking a combination of soy protein 8 grams plus beta-sitosterol 2 grams daily for 40 days lowers LDL cholesterol by 17-20 mg/dL, but does not improve triglyceride or HDL cholesterol levels, when compared to baseline (35013,35039). Other clinical research shows that taking a combination of beta-sitosterol 2.5 grams daily along with cholestyramine (Questran, Bristol Myer Squibb) 8 grams daily for 12 weeks reduces total cholesterol by about 23 mg/dL and LDL cholesterol by 15 mg/dL when compared to baseline, but is less effective than atorvastatin 10 or 80 mg daily (35100).

POSSIBLY EFFECTIVE

• Coronary heart disease (CHD). The US Food and Drug Administration (FDA) has approved an authorized health claim for dietary plant sterols, when taken in doses of at least 3.4 grams daily as part of a diet low in saturated fat and cholesterol, for reducing the risk of CHD. Details: In 2010, the FDA authorized a health claim stating that consuming at least 3.4 grams of plant sterols daily, as part of a diet low in saturated fat and cholesterol, may reduce the risk of heart disease (102365). This health claim is based on evidence showing that plant sterols can lower cholesterol levels. However, there is currently no evidence directly linking dietary intake of plant sterols with a reduced risk for developing CHD.
• Familial hypercholesterolemia. Oral beta-sitosterol, in combination with a cholesterol-lowering diet, seems to reduce low-density lipoprotein (LDL) cholesterol levels in patients with familial hypercholesterolemia. However, it doesn't seem to work as well as sitostanol or bezafibrate. Details: Preliminary clinical research shows that taking beta-sitosterol for 1-4 months while following a cholesterol-lowering diet reduces total cholesterol by 6% to 13% and LDL cholesterol by 6% to 20% in adult and pediatric patients with familial hypercholesterolemia. Beta-sitosterol 2.5-21.1 grams taken in up to three divided doses daily for 1-3 months has been used in adults. Beta-sitosterol 2-4 grams three times daily for 3 months has been used in children and adolescents (3889,5331,5332,5333,35067). Some research suggests that the optimal dose of beta-sitosterol is 6 grams daily; higher doses do not appear to be more effective (5333). However, some research in pediatric patients shows that beta-sitosterol can also decrease levels of high-density lipoprotein (HDL) cholesterol (5332) and that beta-sitosterol appears to be less effective for reducing LDL cholesterol when compared to sitostanol (3889). Furthermore, beta-sitosterol does not appear to improve triglyceride levels (5333). Some research has compared beta-sitosterol to cholesterol-lowering medication. In children with familial hypercholesterolemia, taking beta-sitosterol 1 grams three times daily in combination with the fibrate drug bezafibrate 200 mg once daily for 24 months reduces cholesterol as effectively as taking bezafibrate 200 mg twice daily. However, taking beta-sitosterol 2 grams three times daily is less effective for lowering LDL cholesterol when compared with bezafibrate 200 mg twice daily (5334).

• Allergic rhinitis (hay fever). Although there is interest in using oral beta-sitosterol for allergic rhinitis, there is insufficient reliable information about the clinical effects of beta-sitosterol for this condition.
• Androgenic alopecia. Oral beta-sitosterol has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in males with androgenic alopecia shows that a combination of beta-sitosterol 50 mg plus saw palmetto extract 200 mg taken twice daily for an average of 4.6 months improves subjective scores of hair quantity and quality when compared with baseline (15550). The validity of this finding is limited by the lack of a comparator group.
• Asthma. Although there is interest in using oral beta-sitosterol for asthma, there is insufficient reliable information about the clinical effects of beta-sitosterol for this condition.
• Burns. Topical beta-sitosterol has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research shows that applying an ointment containing sesame oil, beta-sitosterol, berberine, and other plant ingredients (MEBO) is as effective as applying silver sulfadiazine dressing twice daily for healing burns and preventing bacterial infection (13526). Furthermore, this ointment appears to be more effective than povidone-iodine plus bepanthenol cream for reducing pain. The ointment can also shorten the hospital stay of these patients by almost one day when compared with povidone-iodine plus bepanthenol (35118). However, when used for second-degree facial burns, this ointment increases healing time by about 2 days and worsens pain and discomfort when compared with a specific dressing containing ionic silver (Aquacel Ag Hydrofiber) (35117). The ointment has been applied to partial-thickness burns as a thick layer every 4-12 hours for up to 18 days or until release from the hospital in patients aged 2 years and older (13526,35117,35118).
• Cancer. It is unclear if dietary beta-sitosterol is beneficial for cancer prevention. Details: A meta-analysis of population research has found that although the highest intake of plant sterols is associated with a reduced risk of having cancer when compared with the lowest intake, there is no association between beta-sitosterol itself and cancer risk (106084). Also, population research suggests that dietary intake of beta-sitosterol does not affect the risk of colon cancer (34993).
• Chronic prostatitis and chronic pelvic pain syndrome (CP/CPPS). Although there is interest in using oral beta-sitosterol for prostatitis, there is insufficient reliable information about the clinical effects of beta-sitosterol for this condition.
• Esophageal cancer. It is unclear if dietary beta-sitosterol intake influences the outcome of esophageal cancer. Details: In Chinese people with esophageal squamous cell carcinoma, the mortality rate does not seem to differ between those with the lowest versus the highest intake of dietary beta-sitosterol, measured five years before diagnosis (112082).
• HIV/AIDS. Although there is interest in using oral beta-sitosterol for HIV/AIDS, there is insufficient reliable information about the clinical effects of beta-sitosterol for this condition.
• Menopausal symptoms. Although there is interest in using oral beta-sitosterol for menopausal symptoms, there is insufficient reliable information about the clinical effects of beta-sitosterol for this purpose.
• Migraine headache. Although there is interest in using oral beta-sitosterol for migraine headache, there is insufficient reliable information about the clinical effects of beta-sitosterol for this condition.
• Obesity. It is unclear if oral beta-sitosterol is beneficial for obesity. Details: In Chinese adults, higher dietary intake of beta-sitosterol is inversely related to the risk of being overweight. The risk of central obesity specifically is linked to beta-sitosterol intake in males (112083).
• Psoriasis. Although there is interest in using oral beta-sitosterol for psoriasis, there is insufficient reliable information about the clinical effects of beta-sitosterol for this condition.
• Rheumatoid arthritis (RA). It is unclear if oral beta-sitosterol is beneficial for RA. Details: Preliminary clinical research shows that taking a specific supplement (Moducare) containing beta-sitosterol 20 mg and beta-sitosterol glucoside 0.2 mg three times daily for 24 weeks improves pain and symptoms in 28% to 85% of patients with RA when compared with baseline (35200). The validity of this finding is limited by the lack of a comparator group.
• Systemic lupus erythematosus (SLE). Although there is interest in using oral beta-sitosterol for SLE, there is insufficient reliable information about the clinical effects of beta-sitosterol for this condition.
• Thrombocytopenia. Although there is interest in using oral beta-sitosterol for thrombocytopenia, there is insufficient reliable information about the clinical effects of beta-sitosterol for this condition.
• Tuberculosis. It is unclear if oral beta-sitosterol is beneficial for tuberculosis. Details: A small clinical trial shows that taking beta-sitosterol orally as an adjunct to conventional treatment for tuberculosis can increase lymphocyte counts when compared with placebo; however, beta-sitosterol does not seem to decrease the time to cure based on negative sputum culture (5337).
• Upper respiratory tract infection (URTI). Although there is interest in using oral beta-sitosterol for upper respiratory infections such as bronchitis, common cold, exercise-induced respiratory infections, and influenza, there is insufficient reliable information about the clinical effects of beta-sitosterol for these conditions.
• Wound healing. Although there is interest in using topical beta-sitosterol for wound healing, there is insufficient reliable information about the clinical effects of beta-sitosterol for this purpose. More evidence is needed to rate beta-sitosterol for these uses.

POSSIBLY EFFECTIVE

• Raynaud syndrome. Small clinical studies suggest that oral inositol nicotinate may modestly improve symptoms in patients with Raynaud syndrome. Details: Several small clinical trials in adults with Raynaud syndrome shows that taking a specific inositol nicotinate product (Hexopal, Sterling Winthrop) 3-4 grams daily orally for 8-12 weeks modestly improves symptom frequency and severity, including pain, coldness, and vasospasm (498,1544,1545). Several weeks of treatment may be necessary before the full beneficial effects are seen (1544,1545).

• Intermittent claudication. It is unclear if oral inositol nicotinate is beneficial in patients with intermittent claudication. Details: Three, low-quality, clinical studies in adults with intermittent claudication show that taking a specific inositol nicotinate product (Hexopal, Winthrop Laboratories) 4 grams orally, divided in 2-4 doses daily, for 3 months modestly improves walking distance, claudication time, and pressure indices and reduces the severity of walking problems when compared with baseline. However, the studies show conflicting effects of inositol nicotinate when compared with placebo. Differences in smoking status and changes in smoking habits throughout the studies may explain the differing results; however, more data is needed to confirm (55857,55858,55860). Preliminary subgroup analyses also suggest that inositol nicotinate may be less effective in patients with severe or mild intermittent claudication when compared with moderate disease (55860).
• Migraine headache. Although there has been interest in using oral inositol nicotinate for migraine headache, there is insufficient reliable information about the clinical effects of inositol nicotinate for this purpose.
• Peripheral arterial disease (PAD). Although there has been interest in using oral inositol nicotinate for PAD, there is insufficient reliable information about the clinical effects of inositol nicotinate for this purpose.

• Intermittent claudication. Oral use of policosanol can increase walking distance in patients with intermittent claudication. Details: Multiple, small, randomized controlled trials show that taking policosanol 10 mg orally once to twice daily for up to 2 years moderately improves walking distance when compared with placebo, lovastatin, or aspirin, and has similar effects to ticlopidine, in patients with intermittent claudication (2931,65359,65372,65378,69114).

• Angioplasty. It is unclear if oral policosanol is beneficial for patients after angioplasty. Details: Preliminary clinical research has evaluated the addition of policosanol to dual antiplatelet therapy in Chinese patients with high on-treatment platelet reactivity (HPR) who underwent percutaneous coronary intervention with a drug-eluting stent for an acute coronary syndrome. The addition of policosanol 40 mg orally daily with clopidogrel 75 mg daily and aspirin 300 mg daily for 30 days does not further reduce HPR when compared with taking clopidogrel and aspirin alone (100684).
• Coronary heart disease (CHD). It is unclear if oral policosanol is beneficial for patients with CHD. Details: One small clinical study in adults with CHD shows that taking policosanol 5 mg twice daily, alone or in combination with aspirin 125 mg for 20 months, can reduce cardiac events and improve maximum oxygen uptake during a treadmill exercise electrocardiogram (ECG) when compared with pretreatment (2941). Policosanol has also been evaluated as part of combination products for CHD. Clinical research in statin-intolerant patients with CHD treated with a percutaneous intervention (PCI) shows that taking a specific combination product (Armolipid Plus, Rottapharm S.p.A.) containing policosanol, berberine, red yeast rice, folic acid, coenzyme Q10, and astaxanthin daily for 3 months reduces total cholesterol, low-density lipoprotein (LDL) cholesterol, and triglycerides, and increases high-density lipoprotein (HDL) cholesterol, to a greater extent than ezetimibe 10 mg daily. Combining this specific product with ezetimibe produces additional improvements after 1 year of treatment when compared with either agent alone (97232). Other clinical research in patients with CHD treated with PCI shows that taking the same product in combination with a low-dose statin for 3 months reduces total cholesterol and LDL cholesterol and increases HDL cholesterol when compared with low-dose statin treatment alone (97233). It is unclear if the benefits of this combination product are due to policosanol, other ingredients, or the combination.
• Familial hypercholesterolemia. It is unclear if oral policosanol is beneficial for patients with familial hypercholesterolemia. Details: Preliminary clinical research shows that taking a specific form of policosanol (Lesstanol Octa-60, Garuda International) 20 mg orally daily for 12 weeks does not significantly decrease total or low-density lipoprotein (LDL) cholesterol in patients with familial hypercholesterolemia (14404).
• Hypercholesterolemia. It is unclear if oral policosanol is beneficial for patients with hypercholesterolemia. Details: Current clinical research on the use of policosanol for hyperchloremia is conflicting. The reasons for these discrepant findings are unclear but may be explained by differences in doses, treatment durations, patient populations, and specific policosanol products studied. Clinical research in subjects with hypercholesterolemia, largely conducted by researchers in Cuba, shows that taking policosanol orally 5-20 mg daily for 8-24 weeks lowers total cholesterol by 9% to 29% and low-density lipoprotein (LDL) cholesterol by 11% to 42% and increases high-density lipoprotein (HDL) cholesterol by 7% to 34% when compared with placebo or other controls (2927,2928,2929,2930,2943,2944,14298,14411,65348,65354)(65355,65356,65361,65363,65365,65369,65375,65380,65383,69104)(69105,69106,65362,65351,100178). When compared to conventional drugs, some research also shows that policosanol 10 mg daily lowers total and LDL cholesterol by a similar amount as fluvastatin 20 mg daily and simvastatin 10 mg daily (8147,12190). Atorvastatin 10 mg daily appears to be more effective than policosanol 10 mg daily for lowering total and LDL cholesterol (14411). However, the majority of research conducted outside of Cuba has been contradictory. Research in subjects with hypercholesterolemia, conducted by German, Canadian, Croatia, South African, Netherlands, U.S., and Italian researchers, shows that taking policosanol 10-80 mg daily for 4-12 weeks does not significantly decrease total or LDL cholesterol when compared with placebo (14336,15062,69111,69119,69107,69109,69110,12166,14404). These studies included policosanol derived from Cuban sugar cane, U.S. sugar cane, wheat germ, and red yeast rice and specific policosanol products (Lesstanol Octa-60, Garuda International; Cholesstor, Pharmed Group) (69107,69109,69110,12166,14404). Policosanol has also been studied in combination with other ingredients. Taking a product containing policosanol 10 mg, berberine 500 mg, and red yeast rice 200 mg daily for up to 12 months seems to reduce total cholesterol and LDL cholesterol levels in hypercholesterolemic patients when compared with placebo or ezetimibe 10 mg (34262,34283,34301). Taking a specific combination product (Armolipid Plus, Rottapharm S.p.A.) containing policosanol, berberine, red yeast rice, folic acid, coenzyme Q10, and astaxanthin daily for 8 weeks appears to reduce total cholesterol by 13% and LDL cholesterol by 21%, as well as increasing HDL cholesterol by 5% when compared with baseline in patients with metabolic syndrome and dyslipidemia (89438). A meta-analysis also shows that taking this combination product for up to 1 year reduces total cholesterol by 10%, LDL cholesterol by 14%, and triglycerides by 7%, and increases HDL cholesterol by 4%, when compared with baseline in patients with hypercholesterolemia (92142). It is unclear if the benefits of this combination product are due to policosanol, red yeast rice (which contains monacolin K, a chemical similar to lovastatin), other ingredients, or the combination.
• Hypertension. It is unclear if oral policosanol is beneficial for patients with hypertension. Details: Clinical research in adults with prehypertension shows that taking policosanol 20 mg orally daily for 12 weeks reduces both systolic and diastolic blood pressure by about 7%, compared to non-significant changes with placebo. A lower dose of policosanol 10 mg daily did not improve blood pressure when compared with placebo (100177).
• Metabolic syndrome. Oral policosanol has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research shows that taking a specific combination product (Armolipid Plus, Rottapharm S.p.A.) containing policosanol, berberine, red yeast rice, folic acid, coenzyme Q10, and astaxanthin daily for 18 weeks improves systolic blood pressure, left ventricular mass, and flow-mediated dilation in patients with metabolic syndrome when compared with control (34289). It is unclear if these effects are due to policosanol, other ingredients, or the combination. More evidence is needed to rate policosanol for these uses.

Although, one clinical trial shows that taking policosanol 10 mg twice daily for 2 weeks prior to warfarin dosing does not affect warfarin pharmacokinetics or warfarin response (20083). Furthermore, a study in patients undergoing percutaneous coronary intervention with a drug-eluting stent found that taking policosanol 40 mg plus clopidogrel and aspirin daily for 30 days modestly reduced the risk for minor bleeding events when compared with taking clopidogrel and aspirin alone (100684). Until more is known, use with caution.

General ...Orally, beta-sitosterol is generally well tolerated. Topically, beta-sitosterol seems to be well tolerated.
Most Common Adverse Effects:
Orally: Constipation, diarrhea, gas, indigestion, and nausea.

Dermatologic ...Orally, beta-sitosterol can worsen acne when taken alone or in combination with saw palmetto (5331,15550).

Gastrointestinal ...Orally, beta-sitosterol can cause nausea, indigestion, gas, diarrhea, or constipation (5327,5328). Beta-sitosterol can also reduce the appetite (5334). There is a case report of acute pancreatitis thought to be associated with taking beta-sitosterol in a 57-year-old male. Symptoms started the first day of use, but did not return when he stopped taking beta-sitosterol (106080).
Single reports of reduced appetite, flatulence, and diarrhea have been reported for patients taking a combination of saw palmetto and beta-sitosterol (15550).

General ...Orally, inositol nicotinate is generally well tolerated.
Most Common Adverse Effects:
Orally: Abdominal pain, constipation, diarrhea, flushing, heartburn, liver enzyme elevation, nausea, vomiting.

Cardiovascular ...Orally, inositol nicotinate is converted to niacin and is therefore likely to cause similar side effects as niacin (496). A prostaglandin-mediated flushing reaction is a common adverse effect of oral niacin. A large pooled analysis of clinical studies shows that up to 70% of people may experience flushing with oral niacin (96211). Although flushing can occur with doses of niacin as low as 30 mg daily, it is more common with the larger doses of 500-2000 mg used for treatment of dyslipidemia (4889,26089,93341,93345). Inositol nicotinate is often promoted as a "no-flush" niacin; however, this benefit has not been demonstrated in clinical trials.

Dermatologic ...Orally, inositol nicotinate is converted to niacin and is therefore likely to cause similar side effects as niacin, including pruritus (496).

Endocrine ...Orally, inositol nicotinate is converted to niacin and is therefore likely to cause similar side effects as niacin (496). Niacin can impair glucose tolerance in a dose-dependent manner. Dosages of niacin 3-5 grams daily appear to increase blood glucose in patients with or without diabetes, while dosages of 1.5 grams or less have minimal effects (12033). Because inositol nicotinate is converted to niacin, it may also impair glucose tolerance (496).

Gastrointestinal ...Orally, inositol nicotinate is converted to niacin and is therefore likely to cause similar side effects as niacin, including gastrointestinal complaints such as nausea, vomiting, bloating, heartburn, diarrhea, and constipation (496). These adverse effects from niacin may be reduced by taking it with meals or antacids, and usually disappear within two weeks of continued therapy (4851,11690,26094).

Hematologic ...Orally, inositol nicotinate is converted to niacin and is therefore likely to cause similar side effects as niacin, including hyperuricemia (496).
