Hello {{First Name|there}},
This month’s Bioactive Spotlight explores sea buckthorn, a bright orange berry that has been used for centuries in traditional medicine across Asia and Europe.
Researchers are studying sea buckthorn’s unique mix of bioactive compounds for their role in inflammation, metabolic disease, and cancer biology.
→ Sea buckthorn has gained specific attention for its potential role in vaginal and uterine health, particularly during menopause and inflammatory gynecologic conditions.
What Makes Sea Buckthorn Unique?
Sea buckthorn berries contain a wide range of bioactive compounds, several of which we’ve explored in past newsletters:
Polyphenols → including flavonoids such as quercetin, which effects inflammation and vascular signaling
Carotenoids → including lycopene and zeaxanthin, which are associated with antioxidant activity and eye health
Vitamins C and E → antioxidants that protect cells from oxidative damage
Polyunsaturated fatty acids, → omega-3, -6, -9, and the relatively rare omega-7 palmitoleic acid
→ Very few berries pack such a dense concentration of bioactive compounds into such a small fruit.
Sea Buckthorn and Women’s Health: What Does the Research Actually Show?
Traditionally, sea buckthorn has been used in gynecologic conditions including uterine inflammation and endometriosis. Researchers believe some of these effects may relate to the plant’s carotenoids, flavonoids, fatty acids, and antioxidant compounds.
However, an important question remains:
→ Which effects have actually been demonstrated in humans, and which are still theoretical?
Vaginal Health & Menopause
One of the strongest human data areas involves vulvovaginal atrophy, a condition common after menopause in which declining estrogen contributes to thinning, dryness, and irritation of vaginal tissues.
Several studies have found sea buckthorn oil was associated with reduced symptoms such as dryness, burning, and irritation in postmenopausal women
Researchers propose these effects may relate to:
Improved mucosal barrier integrity
Fatty acid support for epithelial tissues
Reduced inflammatory signaling
Changes in vascular and tissue repair pathways
→ A sea buckthorn-containing vaginal gel has even been developed for symptoms of vulvovaginal atrophy.
Endometriosis, Angiogenesis & Emerging Research
Sea buckthorn is also being studied in endometriosis and inflammatory gynecologic disease because these conditions involve both chronic inflammation and abnormal angiogenesis.
Endometriosis lesions rely on VEGF-driven blood vessel growth to survive and expand. Researchers are investigating whether sea buckthorn compounds influence VEGF signaling and endometrial tissue remodeling.
It has also shown anti-cancer effects in ovarian cancer cell studies slowing cell proliferation and triggering apoptosis
But most of these findings come from:
Cell culture studies
Animal models
Isolated compounds rather than whole berries or oils
→ Sea buckthorn may affect vaginal tissue biology, but human evidence remains limited and many health claims exceed current research.
Where Sea Buckthorn Is Commonly Found
The berries are naturally tart and are often blended with other fruits in juices and food products. They are also commonly found in:
• Seed and pulp oils
• Juice concentrates and beverages
• Purees and jams
• Capsules and dietary supplements
Importantly, different preparations may contain very different concentrations bioactive compounds.
→ This makes it difficult to compare products directly or generalize findings across studies.
