• Complete fatty acid spectrum: Omega-3, 6, 7, and 9 fatty acids support brain, heart, and skin health

What makes sea buckthorn truly exceptional is its status as one of the rare plant sources containing all four omega fatty acids. This comprehensive fatty acid profile contributes to its wide-ranging health benefits.

The abundant antioxidants in sea buckthorn oil help neutralize harmful free radicals, potentially slowing the aging process and reducing the risk of chronic diseases including cardiovascular conditions and certain cancers.

Additionally, sea buckthorn contains significant amounts of phytosterols—plant compounds structurally similar to cholesterol that can block dietary cholesterol absorption in the intestines, supporting cardiovascular health.

2. Promotes Healthy, Radiant Skin

Sea buckthorn oil has earned its reputation as a premium natural skincare ingredient, used for centuries to enhance skin health and appearance.

The oil’s remarkable skin benefits stem from its rich concentration of unsaturated fatty acids, antioxidants, phytosterols, carotenoids, and vitamins E and K. These nutrients work together to maintain skin integrity, accelerate cellular renewal, and protect against environmental damage.

One of sea buckthorn oil’s most valuable components for skin health is palmitoleic acid (omega-7), a fatty acid naturally present in human skin. This omega-7 fat plays a crucial role in wound healing and burn recovery, making sea buckthorn oil particularly effective for damaged or compromised skin.

The oil is exceptionally rich in omega-6 fatty acids, including linoleic acid and gamma-linolenic acid. These essential fats help manage various skin conditions such as acne and psoriasis while preventing dryness, flaking, and scaling.

Research indicates that compounds in sea buckthorn oil may protect skin from UV radiation damage, though it should not replace proper sun protection measures.

Modern skincare formulations frequently incorporate sea buckthorn oil in anti-aging products, wrinkle-reducing serums, and treatments for dry, irritated, or inflamed skin conditions. Its ability to nourish deeply while remaining lightweight makes it suitable for various skin types.

3. Supports Cardiovascular Health

Sea buckthorn oil offers multiple mechanisms for supporting heart health, making it a valuable addition to a heart-healthy lifestyle.

The oil’s abundant phytosterols provide both antioxidant and anti-inflammatory benefits, helping protect the cardiovascular system from damage and disease. These plant compounds interfere with cholesterol absorption in the digestive tract, preventing LDL (bad) cholesterol from accumulating in blood vessels and forming dangerous arterial plaques.

Sea buckthorn oil contains significant amounts of quercetin, a powerful antioxidant flavonoid associated with reduced cardiovascular disease risk. Quercetin helps maintain healthy blood vessel function and reduces oxidative stress throughout the circulatory system.

Clinical research has demonstrated promising results for cardiovascular health. A 2017 study found that individuals with high blood pressure who consumed 0.75 mL of sea buckthorn oil daily experienced notable reductions in blood pressure levels. Participants with elevated cholesterol also saw improvements in triglycerides, total cholesterol, and LDL cholesterol.

However, researchers noted that effects were more pronounced in individuals with existing cardiovascular concerns, while those with normal blood pressure and cholesterol levels experienced smaller changes.

The combination of healthy fatty acids, antioxidants, and phytosterols makes sea buckthorn oil a comprehensive natural approach to cardiovascular wellness.

4. Helps Maintain Healthy Blood Sugar Levels

Emerging research suggests that sea buckthorn oil may play a beneficial role in blood sugar management and diabetes prevention.

The oil appears to work by supporting healthy insulin secretion from pancreatic cells and enhancing insulin sensitivity in body tissues. When cells respond more effectively to insulin, glucose can be removed from the bloodstream more efficiently, helping maintain stable blood sugar levels.

A 2021 clinical study examined 38 individuals with impaired glucose regulation—a condition that increases type 2 diabetes risk. One group consumed 90 mL of sea buckthorn puree daily for five weeks, while a control group received a placebo. Researchers found that participants consuming sea buckthorn experienced a statistically significant decrease in fasting blood sugar levels compared to the placebo group.

While the magnitude of blood sugar reduction was modest (0.14 mmol/L), the study demonstrates sea buckthorn’s potential as part of a comprehensive approach to blood sugar management.

The better your body secretes and responds to insulin, the lower your risk of developing type 2 diabetes and its associated complications. Sea buckthorn oil may provide supportive benefits alongside healthy diet and lifestyle choices.

Additional research is needed to fully understand optimal dosing and long-term effects, but current evidence suggests promise for metabolic health support.

5. Strengthens Immune System Function

Sea buckthorn oil may enhance your body’s natural defense mechanisms against infections and illness.

Much of this immune-boosting effect is attributed to the oil’s high palmitoleic acid content. This omega-7 fatty acid supports immune cell function while helping regulate inflammatory responses—crucial for maintaining balanced immunity that protects without overreacting.

The oil’s impressive antioxidant content further supports immune health. Flavonoids such as quercetin and isorhamnetin have been shown to enhance immune system activity and increase resistance to various pathogens.

These beneficial plant compounds combat oxidative stress by neutralizing unstable molecules called free radicals. When free radicals accumulate, they can damage immune cells and compromise your body’s ability to fight off infections. Sea buckthorn’s antioxidants help protect immune cells, allowing them to function optimally.

The combination of omega fatty acids, vitamins, and phytonutrients in sea buckthorn oil creates a synergistic effect that may help your immune system respond more effectively to challenges.

While animal and laboratory studies show promising immune-enhancing effects, more human clinical trials are needed to fully understand how sea buckthorn oil influences immunity in real-world conditions.

6. Protects and Supports Liver Function

Your liver performs over 500 vital functions, and sea buckthorn oil may help keep this crucial organ healthy.

The oil contains an ideal combination of healthy fats, vitamin E, and carotenoids—all of which help protect liver cells (hepatocytes) from damage caused by toxins, inflammation, and metabolic stress.

A 2018 animal study found that multiple compounds in sea buckthorn oil helped reduce liver inflammation, minimize cellular injury, and prevent fibrosis (scarring). The oil also appeared to promote liver tissue regeneration, suggesting potential therapeutic applications for liver conditions.

Additional research from 2020 examined sea buckthorn’s effects on alcohol-associated liver disease in mice. The study found that sea buckthorn fermentation liquid significantly improved liver function markers and positively influenced gut microbiome composition—an important factor since gut health directly impacts liver wellness.

The liver plays a central role in detoxification, metabolism, and nutrient processing. Supporting liver health with nutrient-dense foods and supplements like sea buckthorn oil may contribute to overall wellbeing and longevity.

While these preliminary findings are encouraging, human studies are necessary to confirm these liver-protective effects and establish appropriate therapeutic uses.

7. May Offer Cancer-Protective Properties

The flavonoids and antioxidants in sea buckthorn oil show promising anticancer potential in preliminary research.

Sea buckthorn is particularly rich in quercetin, a flavonoid that has demonstrated cancer-fighting properties in laboratory studies. A 2020 research review examined numerous in vitro (test tube), in vivo (animal), and ex vivo studies showing that quercetin may help destroy cancer cells while leaving healthy cells intact.

Other antioxidants abundant in sea buckthorn—including carotenoids and vitamin E—may also provide protective benefits against cellular mutations that can lead to cancer development.

A 2018 scientific review highlighted animal studies suggesting that sea buckthorn extracts might help prevent cancer cell spread (metastasis) and protect healthy tissues from damage during radiotherapy treatment. This protective effect could potentially help cancer patients tolerate treatment better while maintaining quality of life.

The oil’s comprehensive antioxidant profile helps neutralize free radicals and reduce oxidative stress—both factors that contribute to DNA damage and cancer risk.

It’s crucial to note that these findings come from laboratory and animal research. No human clinical trials have yet demonstrated cancer-fighting effects, so sea buckthorn oil should never be considered a cancer treatment or preventive therapy. Anyone concerned about cancer risk or dealing with a cancer diagnosis should work closely with qualified healthcare providers.

8. May Improve Digestive Health

Sea buckthorn oil has been used in traditional medicine systems to soothe and heal the digestive tract.

Research suggests that sea buckthorn may help reduce gastrointestinal inflammation—a root cause of many digestive complaints. The oil’s anti-inflammatory compounds help calm irritated digestive tissues and support the protective mucous lining of the stomach and intestines.

Studies have explored sea buckthorn’s potential for preventing and treating stomach ulcers. The oil appears to strengthen the stomach’s mucosal barrier, making it more resistant to damage from acid, bacteria, and irritating substances.

The omega-7 fatty acid palmitoleic acid, abundant in sea buckthorn, plays a particularly important role in maintaining healthy mucous membranes throughout the digestive system.

Additionally, sea buckthorn contains compounds that may support beneficial gut bacteria while discouraging harmful microorganisms, contributing to a healthier microbiome balance.

While traditional use and preliminary research are encouraging, more clinical studies are needed to establish specific digestive benefits and optimal therapeutic approaches.

9. Relieves Dry Eye Symptoms

Sea buckthorn oil shows promise as a natural remedy for dry eye syndrome, an increasingly common condition in our screen-focused world.

A 2019 clinical study found that daily sea buckthorn supplementation significantly reduced eye redness and burning sensations in participants suffering from dry eyes. The improvement was attributed to the oil’s omega fatty acids, which support the production of the tear film’s lipid layer.

The tear film consists of three layers—mucous, aqueous, and lipid. The outer lipid layer prevents tears from evaporating too quickly. Sea buckthorn’s omega-7 fatty acids appear to improve the quality of this lipid layer, helping eyes stay comfortably lubricated.

The oil’s anti-inflammatory properties may also help reduce irritation and inflammation of the eye surface and eyelids, conditions that often accompany chronic dry eyes.

For individuals who spend long hours at computers, work in dry environments, or experience dry eyes as they age, sea buckthorn oil may offer natural relief when used consistently over time.

10. Supports Menopausal Wellness

Women experiencing menopause may find relief from certain symptoms through sea buckthorn oil supplementation.

Research has focused particularly on sea buckthorn’s ability to address vaginal dryness—one of the most common and uncomfortable menopausal symptoms. The oil’s omega-7 fatty acids help maintain moisture in mucous membranes throughout the body, including vaginal tissues.

Studies suggest that sea buckthorn oil may serve as an effective alternative for women who cannot or prefer not to use hormone replacement therapy. The oil works by supporting the body’s natural moisture production rather than introducing external hormones.

Some women report that regular sea buckthorn supplementation helps with other menopausal concerns as well, though more research is needed to confirm these additional benefits.

The omega fatty acids in sea buckthorn support overall cellular health and may help maintain comfortable, healthy tissues during hormonal transitions.

11. Enhances Hair Health and Appearance

Sea buckthorn oil is increasingly popular in natural haircare for its ability to improve hair texture, shine, and overall health.

The oil contains small amounts of lecithin, a fatty substance that helps remove excess sebum (oil) from hair and scalp without stripping away necessary moisture. This balancing action makes it suitable for various hair types.

Research indicates that sea buckthorn oil may help repair damaged hair by restoring elasticity and strength to hair strands. This makes hair more resistant to breakage and better able to withstand styling stress.

The vitamins and fatty acids in sea buckthorn nourish hair follicles, potentially supporting healthier hair growth. Vitamin E, in particular, provides antioxidant protection to follicle cells, while omega fatty acids support the structural integrity of hair shafts.

Many people use sea buckthorn oil as a pre-shampoo treatment, leave-in conditioner, or scalp massage oil to harness these hair-enhancing benefits.

How to Use Sea Buckthorn Oil

Sea buckthorn oil can be used both internally and externally, depending on your health goals.

For internal use: Sea buckthorn oil is available in liquid form and capsules. Typical dosages range from 0.5 to 1.5 mL daily, though you should follow product-specific recommendations or consult a healthcare provider for personalized guidance.

For topical application: Pure sea buckthorn oil can be applied directly to skin, though many people prefer diluting it with a carrier oil due to its intense color (it may temporarily stain skin orange). It can also be found in creams, serums, and skincare products at lower concentrations.

When using sea buckthorn oil for the first time, start with a small amount to ensure you don’t experience any sensitivity reactions. Apply a patch test to a small skin area before widespread use.

The oil’s deep orange color comes from its rich carotenoid content—this is normal and indicates quality. However, be aware that it may stain clothing or bedding if applied liberally before dressing.
