Nutrition and Key Components of Sea Buckthorn 

Sea buckthorn is stuffed with an array of nutrients, making it one of the most nutrient-loaded plants in nature. It has vital vitamins, minerals, organic acids, amino acids, and bioactive compounds. 

1. Vitamins and Minerals 

Sea buckthorn is a top-notch source of vitamins A, C, E, and K, with key minerals like iron, calcium, magnesium, potassium, copper, and zinc. These vitamins and minerals play vital roles in keeping our overall health and well-being in shape. For instance, vitamin C boosts immunity and aids collagen production in the skin, while vitamin E is a powerful antioxidant that protects cells from damage. 

2. Carbohydrates 

While not a rich source of carbohydrates, sea buckthorn does contain moderate amounts of dietary fiber. Fiber is key for supporting gut health and maintaining regular bowel movements. 

3. Organic Acids and Amino Acids 

Sea buckthorn is full of different organic acids like quinic, malic, and citric acids that contribute to its tart taste. These organic acids also have several health benefits, including antioxidant and antimicrobial benefits. Furthermore, sea buckthorn contains essential amino acids, which our body needs for protein synthesis and energy production. 

4. Bioactive Compounds 

Sea buckthorn is remarkably abundant in bioactive compounds like carotenoids, polyphenols, fatty acids, and phytosterols. These compounds are mainly accountable for the numerous health benefits linked with sea buckthorn. 

  • Carotenoids 

Carotenoids like beta-carotene, lutein, and zeaxanthin are vital nutrients that add to healthy vision and support immune function. They also act as antioxidants, defending cells from damage caused by free radicals. 

  • Polyphenols 

Polyphenols are potent antioxidants found in sea buckthorn, including flavonoids like quercetin and isorhamnetin. These compounds offer a range of health  benefits, like  reducing inflammation, avoiding heart disease, and even showing anti-cancer property. 

  • Fatty Acids 

Sea buckthorn stands out as it contains all four vital omega fatty acids: omega-3, omega-6, omega-7, and omega-9. These fatty acids play key roles in maintaining cell function, reducing inflammation, and boosting heart health. 

  • Phytosterols 

Phytosterols, such as beta-sitosterol, are plant compounds found in sea buckthorn. They have several health benefits, including delaying cholesterol uptake, reducing inflammation, and aiding cardiovascular health. 

Potential Health Benefits of Sea Buckthorn Oil 

Thanks to its rich nutrient profile and many bioactive compounds, sea buckthorn oil is proposed to have many potential health benefits, which are discussed below.  

1. Skin Protection and Dermatological Effects 

Sea buckthorn oil is widely employed to protect and nourish skin. It’s packed with essential fatty acids, antioxidants, and vitamins that uphold skin integrity, which are proposed to speed up wound repair, and reduce signs of aging. 

  • Eczema 

Studies suggest that omega-6 and omega-7 fatty acids in sea buckthorn oil might aid in lowering eczema symptoms and improving skin barrier function. However, more recent studies are needed for stronger evidence behind these findings. 

  • Wound  Repair 

The wealth of essential fatty acids, specifically palmitoleic acid, in sea buckthorn oil may aid wound  repair.  Topical application of sea buckthorn oil has been proven to speed up the recovery process for burns, cuts, and diverse forms of skin wounds. More research is needed. 

2. Promoting Heart Health  

Sea buckthorn oil is acknowledged for supporting heart health because of its rich content of phytosterols, healthy fats, and antioxidants. These nutrients are proposed to help lower cholesterol levels,  reduce blood clotting, and bring down blood pressure, thus strengthening overall cardiovascular health. More scientific probing concerning heart health is warranted.  

3. Blood Sugar Management and Anti-Diabetes 

Early research suggests eating sea buckthorn berries or their extracts may help control blood sugar levels in those with diabetes or pre-diabetes. The plant’s antioxidant properties might have a part to play in boosting insulin sensitivity and glucose metabolism. However, more research is required.  

4. Immune System Boost 

The high count of flavonoids, antioxidants, and essential nutrients in sea buckthorn boosts a strong immune system by increasing resistance to illnesses. Studies have shown that sea buckthorn extracts may protect against certain infections, like influenza, herpes, and HIV viruses. However, more robust studies probing into this are required. 

5. Liver Health Support and Hepatoprotective Activity 

Sea buckthorn oil is known for its hepatoprotective abilities, which can be tied to its healthy fats, vitamins, and carotenoids. Taking the oil is supposed to improve liver function markers and reduce the risk of liver diseases. More research is warranted.  

6. Anticancer Potential 

Research indicates the polyphenols and antioxidants in sea buckthorn oil may have anticancer effects. Compounds like quercetin have been found to help wipe out cancer cells in laboratory studies. However, robust research in humans is needed to confirm these effects. 

7. Anti-Inflammatory Properties 

Sea buckthorn oil contains various polyphenols and fatty acids with anti-inflammatory property. Regular intake of the oil may help to ease symptoms of lasting inflammation and halt the growth of inflammation-linked conditions. However, more scientific probing concerning this is required.  

8. Antimicrobial and Antiviral Activity 

Sea buckthorn oil shows antimicrobial and antiviral activity owing to its bioactive compounds. Some studies reported sea buckthorn extracts may defend against harmful bacteria, fungi, and viruses. More robust studies are required to compare them with the antimicrobials already available. 

9. Neuroprotective Activity 

There’s budding evidence suggests the possible neuroprotective effects of sea buckthorn oil. Its antioxidant properties may protect brain cells from damage linked to age or environmental factors. Research on this is limited right now. 

10. Anti-Obesity Effects and Weight Management 

While more research is needed, some studies suggest that sea buckthorn oil may help control obesity. The oil’s antioxidant and anti-inflammatory qualities may back metabolic health and assist in weight management efforts. However, more research is warranted to corroborate these claims. 

Other Potential Benefits of Sea Buckthorn 

Sea buckthorn might offer other potential benefits, although more research is required to fully understand these effects. 

  • Anti- hyperlipidemia Activity 

Sea buckthorn might aid in bringing down blood lipid levels and reduce the risk of getting hyperlipidaemia, a condition marked by high levels of fats in the bloodstream. This effect is probably because of the presence of phytosterols and omega fatty acids in sea buckthorn oil. 

  • Antiplatelet Activity 

Sea buckthorn compounds, like the flavonoid quercetin, might block platelet buildup, thereby reducing the risk of blood clot formation and related issues, such as stroke and heart attack. 

  • Antioxidant Properties 

As we’ve touched on before, sea buckthorn is rich in antioxidants like vitamin C, vitamin E, carotenoids, and polyphenols. These potent substances aid in neutralizing free radicals in the body, which can cause cell damage and boost chronic diseases and aging. 

Possible Side Effects of Sea Buckthorn Oil 

Even though sea buckthorn is mostly considered safe for consumption and use, some people might face side effects or adverse reactions. 

  • Common Side Effects 

Some people could face gut issues, such as belly discomfort, diarrhoea, or nausea, after taking sea buckthorn products. Applying sea buckthorn oil on the skin might lead to mild irritation or rash in people with sensitive skin. If you face any unexplained symptoms after taking or applying sea buckthorn products, stop their use and check with a healthcare professional.  

  • Severe Side Effects 

Severe side effects from sea buckthorn are rare. However, it’s crucial to think about the possibility of an allergic reaction or drug interaction, especially if you’re on medication or have underlying health issues. 

Precautions and Interactions 

Before using sea buckthorn oil or any related products, it’s key to check with a healthcare professional for guidance, especially if you: 

  • Have low blood pressure. 
  • Have a bleeding disorder. 
  • Are taking blood-thinning drugs.  
  • Are pregnant or breastfeeding.  
  • Are taking diabetes medicines.  
  • Have surgery coming up.
