Sea Buckthorn for Horses: A Natural Solution for Gastric Health | VetGen Nutrition

Discover how sea buckthorn supports equine gastric health. Backed by a peer-reviewed LSU study. Competition-safe and LCH-certified doping-free.

Gastric ulcers are one of the most common health challenges in horses — affecting up to 90% of racehorses and 60% of performance horses. As horse owners and trainers look for natural, competition-safe alternatives to pharmaceutical treatments, sea buckthorn (Hippophae rhamnoides) has emerged as one of the most promising and scientifically supported options.

What Is Sea Buckthorn?

Sea buckthorn is a hardy shrub native to Europe and Asia, prized for centuries in traditional medicine. Its small, bright orange berries are extraordinarily rich in bioactive compounds — in fact, researchers have identified over 190 phytonutrients in sea buckthorn, including:

Omega-7 fatty acids (palmitoleic acid)

Vitamins C and E — in concentrations far exceeding most fruits

Carotenoids and flavonoids

Plant sterols and lignans

Essential minerals

This unique nutritional profile makes sea buckthorn particularly interesting for equine gastric and mucosal health.

The Science: What Research Shows

Key Clinical Study in Horses

The most significant study to date was conducted at Louisiana State University's Equine Health Studies Program and published in the peer-reviewed Journal of Veterinary Internal Medicine:

Eight Thoroughbred and Thoroughbred-cross horses were supplemented with a sea buckthorn berry and pulp emulsion over 35 days. The results were notable:

Glandular ulcer scores (severity and number) were significantly lower in the treated group compared to controls

After 35 days, glandular ulcers in the lower two-thirds of the stomach had resolved in the treated horses

The supplement was well tolerated with no adverse effects reported

While nonglandular (squamous) ulcers showed less response, the results for glandular gastric ulcers — which are notoriously difficult to treat and often linked to stress and feeding management — are highly encouraging.

Why Omega-7 Matters for the Equine Gut

One of sea buckthorn's most distinctive compounds is omega-7 (palmitoleic acid), a rare fatty acid found in high concentrations in the berry oil. Omega-7 plays a direct role in:

Protecting and regenerating mucous membranes lining the stomach and gastrointestinal tract

Reducing inflammation in the gut lining

Supporting mucosal healing after irritation or ulceration

Unlike omega-3 and omega-6 fatty acids, which are widely available in conventional feeds, omega-7 is rare in typical equine diets — making sea buckthorn a genuinely unique nutritional addition.

Antioxidant and Anti-Inflammatory Action

Sea buckthorn's dense antioxidant profile — particularly its flavonoids, carotenoids, and vitamins C and E — provides powerful anti-inflammatory support throughout the digestive tract. These compounds work synergistically to:

Neutralize free radicals that damage the stomach lining

Calm inflammation in the gastric and intestinal mucosa

Support the immune response within the gut

Competition-Safe and Natural

For sport horses and competition riders, supplement safety is non-negotiable. Sea buckthorn is a natural plant extract with no known prohibited substances under FEI or national federation rules. It supports gastric health through nutritional pathways rather than pharmacological mechanisms — making it a clean, responsible choice for horses competing at all levels.

Who Can Benefit?

Sea buckthorn supplementation is particularly relevant for:

Performance and competition horses under physical and psychological stress

Horses prone to gastric ulcers due to intensive training, travel, or irregular feeding

Horses with sensitive digestion or loose droppings

Young horses transitioning to competition schedules

Any horse on a high-concentrate or limited-forage diet

Summary

Sea buckthorn is more than a traditional remedy — it is a scientifically supported, nutrient-dense plant that addresses the root causes of poor gastric health in horses. With a peer-reviewed clinical trial demonstrating measurable reductions in glandular ulcer scores, and a bioactive profile uniquely suited to mucosal protection and regeneration, it represents a compelling natural option for horse owners seeking safe, effective gastrointestinal support.
