What Are the Side Effects of Sea Buckthorn Berries?

4 min read

While largely considered safe and well-tolerated by healthy adults, specific risks and contraindications associated with sea buckthorn have been noted in research, especially regarding drug interactions and particular medical conditions. Its use is not universally risk-free, and careful consideration is necessary, particularly with concentrated supplements. Sea buckthorn berries are naturally packed with a variety of nutrients and fatty acids, but it is this very potency that necessitates caution for some individuals.

Quick Summary

Potential risks of sea buckthorn berries include interactions with blood thinners and diabetes medications, as well as affecting blood pressure and bleeding. Individuals with pre-existing conditions or scheduled for surgery should exercise caution and consult a healthcare provider. Topical application can cause rare skin irritation, while some report mild digestive discomfort.

Key Points

  • Blood-thinning effects: Sea buckthorn may slow blood clotting, increasing the risk of bruising and bleeding, especially when combined with anticoagulant medications.

  • Drug interactions: It can interact with medications for high blood pressure (antihypertensives) and diabetes, potentially causing blood pressure or sugar levels to drop too low.

  • Digestive issues: Some users have reported mild gastrointestinal symptoms, such as discomfort or digestive upset, especially when consuming sea buckthorn oil in large amounts.

  • Skin reactions: Topical application, such as in creams or oils, can cause skin irritation or rashes in individuals with hypersensitivity.

  • Special precautions: Caution is advised for those with bleeding disorders, low blood pressure, or who are scheduled for surgery. Pregnant or breastfeeding women should avoid medicinal use due to insufficient data.

  • Dosage and duration: Long-term medicinal use beyond six months is not well-studied, and overuse can lead to carotenodermia, a harmless yellow-orange skin discoloration.

General Side Effects and Considerations

While sea buckthorn berries are commonly consumed as food and are generally well-tolerated, some individuals may experience mild side effects, especially when taking concentrated supplements or using topical products.

Gastrointestinal Discomfort

In some studies, a small percentage of participants have reported experiencing digestive issues after consuming sea buckthorn oil or berries. These symptoms can include mild stomach upset, indigestion, or changes in bowel habits. Due to its acidity, excessive consumption may also cause heartburn in sensitive individuals.

Skin Irritation

For topical applications, such as creams or oils containing sea buckthorn, there is a small risk of skin irritation or rash. Individuals with hypersensitivity should perform a patch test on a small area of skin before applying it more broadly. Fungal acne-prone skin may also react poorly to sea buckthorn oil.

Drug Interactions and Contraindications

One of the most important considerations for sea buckthorn use involves its potential interactions with certain medications. The bioactive compounds in the berries can influence blood clotting and blood sugar levels, which is critical for people on specific prescription drugs.

Medications that Slow Blood Clotting

Sea buckthorn has been shown to reduce platelet activity and slow blood clotting. For people taking anticoagulant or antiplatelet drugs, such as warfarin (Coumadin), aspirin, or clopidogrel (Plavix), this can significantly increase the risk of bruising and bleeding. Individuals with known bleeding disorders should also avoid sea buckthorn for this reason.

Blood Sugar-Lowering Medications

Some studies suggest sea buckthorn can lower blood sugar levels. This effect could be problematic for individuals with diabetes taking medication to manage their glucose levels. The combination could potentially cause blood sugar to drop too low, leading to hypoglycemia.

Medications for High Blood Pressure

Sea buckthorn has also been observed to lower blood pressure. Taking it alongside antihypertensive drugs could cause blood pressure to drop excessively, a condition known as hypotension. Those with existing low blood pressure should also be cautious.

Precautions and Special Populations

Before Surgery

Because of its potential to slow blood clotting and increase the risk of bleeding, sea buckthorn should be discontinued at least two weeks prior to any scheduled surgery. It is crucial to inform your surgeon about all supplements you are taking.

Pregnancy and Lactation

There is currently insufficient reliable information regarding the safety of sea buckthorn during pregnancy and breastfeeding. Therefore, it is generally advised for pregnant and lactating women to avoid its medicinal use and stick to food amounts, if any.

Children

The safety of sea buckthorn supplements for children under 12 has not been adequately established. It is recommended to consult a pediatrician before giving sea buckthorn oil or berries to young children.

Comparison of Sea Buckthorn Effects

Aspect General Safety for Healthy Adults Risks for Specific Populations
Oral Consumption Generally considered safe, especially in food amounts. Mild digestive upset is rare. Potential for severe bleeding in individuals on blood thinners. Hypoglycemia risk for those with diabetes. May lower blood pressure excessively.
Topical Application Possibly safe for short-term use in creams or oils. Can cause skin irritation or rashes in hypersensitive individuals. Avoid if prone to fungal acne.
Drug Interactions No significant interactions for most people not on medication. Moderate to serious interactions with anticoagulants, antiplatelets, and antihypertensive drugs.
Long-Term Use Safety for long-term medicinal use beyond six months is not well-established. High doses or prolonged use can cause carotenodermia (yellowish skin discoloration). Unknown effects on certain organ systems over extended periods.

Conclusion

While sea buckthorn berries offer numerous health benefits due to their rich nutritional profile, it is imperative to be aware of their potential side effects and interactions. The risk profile is generally low for healthy individuals consuming the berries in food-like quantities. However, those taking specific medications—particularly blood thinners, diabetes drugs, or antihypertensives—or those with certain health conditions must exercise significant caution. As with any dietary supplement, consulting a healthcare provider before starting sea buckthorn is the safest course of action to ensure it does not interfere with your current health status or medications. The potential benefits must always be weighed against the personal health risks.

Understanding Different Sea Buckthorn Products

Sea buckthorn comes in many forms, each with varying concentrations of active compounds, which can affect its potency and potential side effects.

  • Berries/Juice: Generally the safest form, especially when consumed in moderation as part of a regular diet.
  • Seed Oil: A more concentrated form rich in omega fatty acids, which has shown some mild gastrointestinal effects in studies.
  • Berry Pulp Oil: This oil, extracted from the fruit flesh, also contains high levels of beneficial compounds and should be used cautiously.
  • Topical Creams: Used for skin conditions, these can cause irritation in sensitive individuals.

It is important to remember that dietary supplements are not regulated with the same scrutiny as prescription medications. Always look for products that have been independently tested for quality and purity.
