Sea buckthorn (Hippophaë rhamnoides) is an exceptionally vitamin- and nutrient-rich plant whose berries, seeds, and leaves contain plenty of biologically active compounds. Its use reaches back centuries in health-supportive nutrition for both people and animals, and research in recent years has further confirmed its wellbeing-supporting effects—also for dogs and horses.
Sea buckthorn provides the body with valuable fatty acids, vitamins, and antioxidants that particularly support the skin, gut, immune system, and recovery. Its effects extend all the way to the cellular level.
Sea buckthorn’s fatty acids – comprehensive nutrient defence
Sea buckthorn contains a rare broad spectrum of fatty acids: omega-3, -6, -7, and -9. This combination forms a strong foundation for healthy body function.
Omega-3 fatty acids, such as EPA and DHA, are known especially for their ability to reduce “silent,” low-grade inflammation. They support joint wellbeing, skin health, and the normal function of the nervous system and heart. In horses, they also help recovery from physical exertion and support gut wellbeing.
Omega-6 fatty acids, such as linoleic acid, are essential for the structure of the skin and mucous membranes. They participate in the formation of cell membranes and in regulating immune responses. However, it is important to ensure the right balance with omega-3, because excessive omega-6 on its own may increase susceptibility to inflammation.
Omega-7, palmitoleic acid, is a distinctive and relatively rare dietary fatty acid that is especially characteristic of sea buckthorn. Its key strength is protecting mucous membranes. It supports the wellbeing of the surfaces of the mouth, stomach, and intestines and speeds up their renewal. This makes it particularly useful, for example, in connection with digestive issues.
Omega-9 fatty acids, such as oleic acid, complete the fatty acid profile. They help transport nutrients at the cellular level and support heart health.
The power of antioxidants in sea buckthorn
Sea buckthorn contains abundant antioxidant vitamins A, C, and E that protect cells from oxidative stress and support the wellbeing of the immune system, skin, and eyes. In addition, sea buckthorn contains flavonoids and carotenoids, which act as effective antioxidants, as well as phytosterols and tocopherols, which have beneficial effects on heart function and metabolism.
🐴 Benefits of sea buckthorn for horses
In horses, sea buckthorn’s benefits are especially seen in supporting the digestive tract, skin, and recovery.
Several studies show that the oils in sea buckthorn can ease gastric irritation and support mucosal protection. In one study (Huff et al. 2012), sea buckthorn significantly reduced the severity of so-called glandular gastric ulcers in horses. Its effects did not extend to all ulcer types, but the results highlighted sea buckthorn’s potential as a supporter of gut wellbeing.
Skin and coat condition can also benefit from sea buckthorn. The fatty acids and vitamin E support skin moisture balance and improve coat shine. In addition, sea buckthorn’s antioxidant compounds support muscle recovery and joint health, which is especially valuable for sport horses.
Sea buckthorn’s polyphenols may act as immune modulators, helping the horse’s body fight infections and strengthening overall immune defence.
🐶 Sea buckthorn to support canine wellbeing
For dogs, sea buckthorn use has particularly focused on supportive care for skin and gastrointestinal issues and on strengthening immunity.
Omega-7 is especially known for its effects on mucous membranes and skin. It can soothe itching, reduce dryness and flaking, and support coat health. Sea buckthorn is an excellent option for supportive care in atopy and for skin-sensitive individuals. It is also excellent for dogs suffering from dry eyes or cracked paw pads.
In addition, sea buckthorn’s antioxidants and polyphenols support the immune defence of ageing and recovering dogs. At the cellular level, they help counter free radicals and strengthen the body’s defence system.
Sea buckthorn has also been observed to benefit gut health. In a study where dogs were induced to develop gastric ulcers with dexamethasone, sea buckthorn oil proved to be the most effective treatment (Tyagi et al. 2013).
Summary of sea buckthorn’s effects for dogs and horses:
- Skin and coat: Improves skin moisture and shine, and eases skin issues
- Joint health: Reduces inflammation and supports mobility
- Digestion: Protects mucous membranes and supports normal intestinal function
- Immune system: Strengthens defence, especially in older or stressed animals
- Recovery: Speeds recovery from physical exertion
- Mucous membranes of the mouth and eyes: Omega-7 in particular supports the wellbeing of these surfaces
