EFFECTIVE

• Pantothenic acid deficiency. Taking pantothenic acid 5-10 mg daily is effective for treating and preventing pantothenic acid deficiency (15).

POSSIBLY INEFFECTIVE

• Radiation dermatitis. Topical dexpanthenol does not seem to be beneficial for preventing or treating radiation dermatitis. Details: Applying dexpanthenol, an analog of pantothenic acid, twice daily to areas of irradiated skin does not seem to reduce erythema, desquamation, itching, or pain following radiation treatment (7192). Also, applying dexpanthenol 0.5% cream (Bepanthen, Hoffmann LaRoche ) daily during radiation therapy and for 2 weeks after completing radiation therapy is less effective than methylprednisolone aceponate 0.1% cream (Advantan) at reducing radiation-induced skin irritation (67779).

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Acne. Oral or topical pantothenic acid has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: In adults with mild to moderate acne, clinical research shows that taking a specific supplement (Pantothen, Avilan Marketing LLC) providing pantothenic acid 1.1 grams twice daily in addition to other B vitamins for 12 weeks modestly reduces total and non-inflammatory lesion counts when compared with placebo (105188). Also, in adolescents or young adults with mild to moderate acne, preliminary clinical research shows that topical application with a gel containing D-panthenol 4%, hydrogen peroxide 4%, and salicylic acid 0.5% once daily for 60 days modestly reduces acne lesions when compared with baseline (105189). The validity of this finding is limited by the lack of a comparator group.

• Attention deficit-hyperactivity disorder (ADHD). Oral pantothenic acid has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Some small outdated clinical studies in children diagnosed with hyperkinesis suggest that taking calcium pantothenate 1.2 grams, alone or in combination with niacinamide, ascorbic acid, and pyridoxine, does not improve symptoms of hyperactivity when compared with placebo (3351,9957). It is unclear what effects pantothenic may have, if any, in children with a modern diagnosis of ADHD.
• Atopic dermatitis (eczema). It is unclear if topical pantothenic acid is beneficial in infants or children with atopic dermatitis. Details: One preliminary clinical trial in infants and children with stable mild atopic dermatitis shows that topical application of an emollient containing panthenol (Bepanthen, SensiDaily, Bayer Consumer Care AG) for 3 months is as effective as a reference emollient for reducing symptoms and preventing a flare. However, the efficacy of the reference emollient (Stelatopia Emollient Cream, Mustela; Laboratoires Expanscience) is unclear based on available preliminary clinical research (105190).
• Autism spectrum disorder. Although there is interest in using oral pantothenic acid for autism spectrum disorder, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.

Details: A preliminary clinical study shows that use of a dexpanthenol-containing ointment (Bepanthen Wound Healing Ointment, Bayer) once daily modestly reduces the diameter of lesions up to 3 days after fractional carbon dioxide laser resurfacing when compared with petroleum jelly (105743). Also, applying a specific cream (Cicaplast Baume B5 cream, L'Oreal) containing panthenol 5%, madecassoside, copper, zinc, and manganese to one side of the face for 28 days reduces decrustation time by approximately one day when compared with a control emollient. Redness and swelling were lower at 3 days, but there was no difference in pain and burning (105742). It is unclear if these effects are due to pantothenic acid, other ingredients, or the combination.
• Multiple sclerosis (MS). Although there is interest in using oral pantothenic acid for MS, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
• Muscular dystrophy. Although there is interest in using oral pantothenic acid for muscular dystrophy, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.

Details: Although there is interest in using oral or topical pantothenic acid for various forms of chronic pain, including neuropathy and arthritis, there is limited information available about the clinical effects of pantothenic acid for this purpose. One review of preliminary clinical research found that calcium pantothenate does not reduce symptoms of arthritis in patients with rheumatoid arthritis or osteoarthritis (10433).
• Parkinson disease. Although there is interest in using oral pantothenic acid for Parkinson disease, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
• Poison oak and poison ivy dermatitis. Although there is interest in using topical pantothenic acid for poison ivy dermatitis, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
• Postoperative pain. It is unclear if oral pantothenic acid is beneficial for postoperative pain. Details: In post-tonsillectomy patients aged 5-12 years, preliminary clinical research shows that taking pastilles containing dexpanthenol (Bepanthene, Bayer) 100 mg three times daily reduces pain when compared with placebo. Postoperative pain was modestly reduced at 1, 3, 7, and 14 days after surgery (105191).
• Postoperative sore throat. It is unclear if pantothenic acid lozenges are beneficial for postoperative sore throat. Details: Preliminary clinical research shows that taking two lozenges containing dexpanthenol, an analog of pantothenic acid, 200 mg 30 minutes prior to general anesthesia reduces the incidence and severity of postoperative sore throat when compared with a benzydamine hydrochloride or placebo spray (67792).

Details: Preliminary clinical research shows that using a nasal spray (MarPlus) containing dexpanthenol, an analog of pantothenic acid, on the first, second, fourth, and sixth week after endoscopic sinus surgery reduces nasal discharge, but not other symptoms associated with chronic rhinosinusitis, when compared with saline nasal spray (67808).
• Skin irritation. It is unclear if topical dexpanthenol is beneficial for preventing or treating skin irritation due to sodium lauryl sulfate. Details: Preliminary clinical research shows that applying dexpanthenol (Bepanthol Handbalsam), an analog of pantothenic acid, twice daily for 26 days does not prevent sodium lauryl sulfate-induced skin irritation (67785). However, dexpanthenol may be effective for treating skin irritation caused by sodium lauryl sulfate. Use of an ointment containing dexpanthenol 1% to 5% twice daily for up to 30 days following skin exposure to sodium lauryl sulfate seems to reduce skin water loss, skin roughness, and skin inflammation when compared to control (67802,67806).
• Ulcerative colitis. Although there is interest in using oral or rectal pantothenic acid for ulcerative colitis, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
• Vertigo. Although there is interest in using oral pantothenic acid for vertigo, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
• Wound healing. Preliminary clinical research suggests that oral dexpanthenol might be beneficial for wound healing. Details: In post-tonsillectomy patients aged 5-12 years, preliminary clinical research shows that taking pastilles containing dexpanthenol (Bepanthene, Bayer) 100 mg three times daily improves wound healing when compared with placebo. Depending on the type of surgery, wound healing occurred in 2.3-2.9 times as many patients within 7 days of surgery, and in 13% to 35% more patients within 14 days, when compared with placebo (105191). More evidence is needed to rate pantothenic acid for these uses.

POSSIBLY EFFECTIVE

• Burns. Topical cream containing sea buckthorn seems to improve burn healing. Details: Clinical research in patients with second-degree burn injuries shows that topical application of sea buckthorn 40% cream once daily reduces healing time by about 4.5 days when compared with a specific cream containing silver sulfadiazine 1% (Flamexin, Sina Daru) (106091).

POSSIBLY INEFFECTIVE

• Atopic dermatitis (eczema). Neither oral nor topical sea buckthorn products seem to be beneficial for atopic dermatitis. Details: Preliminary clinical research shows that taking sea buckthorn seed and pulp oils 5 grams daily orally for 4 months may improve the severity of atopic dermatitis when compared to pretreatment; however, treatment with the same dose of sea buckthorn seed oil does not have this effect, and the effect of sea buckthorn pulp oil does not appear to be significantly different than placebo (74021). Additionally, applying sea buckthorn 10% or 20% cream topically for 4 weeks does not seem to reduce the severity of atopic dermatitis when compared with placebo in patients with mild-to-moderate atopic dermatitis (74091).

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Asthma. Although there is interest in using oral sea buckthorn for asthma, there is insufficient reliable information about the clinical effects of sea buckthorn for this condition.
• Cancer. Although there is interest in using oral sea buckthorn for reducing morbidity related to cancer and side effects related to chemotherapy, there is insufficient reliable information about the clinical effects of sea buckthorn for these uses.
• Cirrhosis. It is unclear if oral sea buckthorn is beneficial for patients with cirrhosis. Details: Preliminary clinical research shows that taking sea buckthorn extract 15 grams three times daily for 6 months might reduce liver enzymes and markers of liver inflammation in patients with cirrhosis when compared with a control group taking vitamin B complex (16694).
• Common cold. It is unclear if oral sea buckthorn is beneficial for preventing or treating the common cold. Details: Clinical research in healthy volunteers shows that consuming sea buckthorn berries 28 grams daily in frozen puree for 90 days does not reduce the risk of developing the common cold or reduce the duration of symptoms of the common cold when compared with placebo (16692).
• Diabetes. Although there is interest in using oral sea buckthorn for diabetes, there is insufficient reliable information about the clinical effects of sea buckthorn for this condition.
• Dry eye. It is unclear if oral or topical sea buckthorn is beneficial for dry eye. Details: Preliminary clinical research in adults with dry eye shows that taking a specific sea buckthorn seed and pulp oil product (Omega-7, Aromtech Ltd.) 1 gram orally twice daily for 3 months reduces subjective assessments of eye redness and burning and reduces tear film osmolarity when compared with placebo (17406,74069). Preliminary clinical research also shows that using an eyelid spray containing sea buckthorn seed oil 0.4% and sodium hyaluronate 0.02% (Aromtech Ltd., and Finnsusp Ltd.) four times daily for 1.5 months reduces symptoms of dryness and watering by a small amount when compared to a control spray. However, there was no effect on feelings of grittiness, burning, redness, or other symptoms (102845).
• Dry skin. Although there is interest in using topical sea buckthorn for dry skin, there is insufficient reliable information about the clinical effects of sea buckthorn for this condition.
• Dyslipidemia. It is unclear if oral sea buckthorn is beneficial for hyperlipidemia. Details: Some clinical research shows that sea buckthorn berries and extracts can improve the lipid profile in people with hyperlipidemia and/or nonalcoholic fatty liver disease (NAFLD). In a meta-analysis of 11 studies from China and Finland, consuming sea buckthorn berries or extracts for between 12 days and 4 months decreased total cholesterol and low-density lipoprotein (LDL) cholesterol by about 24 mg/dL and triglycerides by about 41 mg/dL and increased high-density lipoprotein (HDL) cholesterol by about 10 mg/dL when compared with baseline or a control group (96555). The sea buckthorn doses and formulations used in these studies were not identified. Additionally, a very small clinical study in females aged 50-61 with hypercholesterolemia shows that drinking sea buckhorn juice (ZAMIO, Ltd) 100% 50 mL daily for 8 weeks modestly improves HDL by about 2 mg/dL and LDL by 10 mg/dL, but does not impact total cholesterol or triglycerides when compared to baseline (112171). However, the validity of these findings is limited by the lack of a comparator group. In contrast, clinical research in patients with hypercholesterolemia shows that taking sea buckthorn puree 30 grams three times daily for 90 days does not improve lipid markers or blood pressure when compared with placebo (106090).
• Dyspepsia. It is unclear if oral sea buckthorn is beneficial for dyspepsia. Details: Preliminary clinical research shows that taking sea buckthorn dry emulsion (prepared with the fruit juice and oil) daily for 8 weeks increases levels of the appetite regulators leptin and neuropeptide Y, which tend to be lower in children with functional dyspepsia; however, sea buckthorn does not appear to improve gastric emptying rates in these patients. Doses were administered according to age: 2.5 grams twice daily for children aged 1-3 years, 5 grams twice daily for children aged 4-6 years old, and 7.5 grams twice daily for children aged 7 years (94800).
• Gout. Although there is interest in using oral sea buckthorn for gout, there is insufficient reliable information about the clinical effects of sea buckthorn for this condition.
• Hypertension. It is unclear if oral sea buckthorn is beneficial for hypertension. Details: A meta-analysis of preliminary clinical research in patients with essential hypertension shows that taking sea buckthorn flavones 10-30 mg three times daily for 1-8 months reduces systolic and diastolic blood pressure to a similar extent as calcium channel blockers and angiotensin converting enzyme (ACE) inhibitors (74090).
• Impaired glucose tolerance (prediabetes). It is unclear if oral sea buckthorn is beneficial for prediabetes. Details: A small clinical trial in patients with impaired glucose tolerance shows that taking sea buckthorn fruit puree 90 mL daily in three divided doses for 5 weeks modestly reduces fasting levels of blood glucose when compared with taking placebo. There was no effect on postprandial glucose levels or blood pressure (106088).
• Kidney failure. It is unclear if oral sea buckthorn oil is beneficial for patients on hemodialysis. Details: Preliminary clinical research shows that taking sea buckthorn oil 2 grams daily for 8 weeks does not improve levels of urea, creatinine, or calcium, reduce markers of inflammation, or improve salivary flow rate when compared with placebo in patients with chronic kidney disease (CKD) who are receiving hemodialysis (94798).
• Melasma. Although there is interest in using topical sea buckthorn for melasma, there is insufficient reliable information about the clinical effects of sea buckthorn for this condition.
• Nephrotic syndrome. It is unclear if oral sea buckthorn is beneficial for nephrotic syndrome. Details: Preliminary clinical research in patients with idiopathic nephrotic syndrome shows that taking hydroalcoholic extract of sea buckthorn 350 mg orally twice daily for 3 months in addition to standard therapy reduces edema, anorexia, and the extent of proteinuria when compared to baseline. It is unclear if the effects of sea buckthorn plus standard therapy are significantly better than the effects of standard therapy alone (94799).
• Obesity. It is unclear if oral sea buckthorn is beneficial for obesity. Details: Preliminary clinical research shows that taking sea buckthorn berries, berry oil, or phenolic alcoholic extract does not reduce body weight in overweight or obese females, although it seems to reduce low-density lipoprotein (LDL) cholesterol (35463,94796).
• Peptic ulcers. Although there is interest in using oral sea buckthorn for peptic ulcers, there is insufficient reliable information about the clinical effects of sea buckthorn for this condition.
• Psoriasis. It is unclear if topical sea buckthorn is beneficial for psoriasis. Details: One small clinical study in patients with previously untreated psoriasis shows that topically applying an unknown amount of sea buckthorn fruit extract suspended in corn oil twice daily for 8 weeks reduces the severity of psoriasis lesions when compared with corn oil alone (102844).
• Radiation dermatitis. Although there is interest in using topical sea buckthorn for radiation dermatitis, there is insufficient reliable information about the clinical effects of sea buckthorn for this condition.
• Rheumatoid arthritis (RA). Although there is interest in using oral sea buckthorn for RA, there is insufficient reliable information about the clinical effects of sea buckthorn for this condition.
• Sunburn. Although there is interest in using topical sea buckthorn for sunburn prevention, there is insufficient reliable information about the clinical effects of sea buckthorn for this condition.
• Vaginal atrophy. It is unclear if oral or intravaginal sea buckthorn is beneficial for vaginal atrophy. Details: Preliminary clinical research shows that taking 3 grams of sea buckthorn oil daily for 3 months does not improve vaginal dryness, itching, burning, pH, or elasticity when compared with placebo in postmenopausal individuals with vaginal atrophy (94797). Topical sea buckthorn oil has also been evaluated, in combination with other ingredients. Clinical research in adults with postmenopausal vulvovaginal atrophy shows that intravaginal application of a specific gel (Meclon Idra Alfasigma, Giellepi) containing sea buckthorn oil, aloe vera, 18-beta-glycyrrhetic acid, hyaluronic acid, and glycogen modestly improves sexual function and reduces vaginal pain, dyspareunia, and symptoms such as vaginal dryness, itching, and burning when compared with a placebo gel. The gel was used daily for 14 days and then twice weekly for 60 days after a 2-week washout (106089). It is unclear if these benefits are due to sea buckthorn oil, other ingredients, or the combination.
• Wound healing. Although there is interest in using topical sea buckthorn for healing of pressure ulcers, skin ulcers, or other wounds, there is insufficient reliable information about the clinical effects of sea buckthorn for this purpose.
• Wrinkled skin. Oral sea buckthorn oil has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in people with facial photodamage and severe fine wrinkling shows that taking a specific combination product (GliSODin Skin Nutrients Advanced Anti-Aging Formula, Isocell North America Inc.) as one capsule orally three times daily for 90 days, in addition to applying tazarotene 0.1% cream, improves the appearance of wrinkles, hyperpigmentation, and photodamage when compared with using tazarotene 0.1% cream alone. Three capsules of this product contain sea buckthorn berry oil 200 mg, krill oil 600 mg, zinc 10 mg, vitamin D 400 IU, cacao bean extract 100 mg, hyaluronic acid 30 mg, red clover flower isoflavones 30 mg, and a specific proprietary ingredient called GliSODin 500 mg (91778). It is not clear if these effects are due to sea buckthorn, the other ingredients, or the combination. More evidence is needed to rate sea buckthorn for these uses.
