Sea Buckthorn Oil
Omega/Fatty Acid ·Exploratory record · not publication-reviewed ·Updated July 13, 2026
Sea buckthorn oil is a fatty acid-rich oil from Hippophae rhamnoides seed, pulp, or berry used for mucosal dryness, skin dryness, and vaginal dryness in menopause. A randomized trial in postmenopausal women found improvement in some vaginal epithelial integrity outcomes with 3 g/day, but symptom effects were modest and not equivalent to estrogen therapy. It should be used cautiously with anticoagulant or antiplatelet therapy and should not delay evaluation of pain, bleeding, or infection.

NutriStack rates the overall evidence as emerging. A typical adult dose is 1-3 g/day oil softgels; 3 g/day was used in a postmenopausal vaginal atrophy trial, commonly taken as mixed sea buckthorn seed and berry oil with disclosed palmitoleic acid content.

- Fishy or oily burps
- Nausea
- Loose stools
- Pregnancy and breastfeeding without clinician guidance
- Use with anticoagulants or antiplatelet drugs without clinician review
The bottom line
Evidence rating emerging. Most-documented uses: may support vaginal mucosal integrity in postmenopausal dryness, may support dry eye or mucosal dryness symptoms, may improve skin hydration in some users. 3 sources indexed (2014–2024), with 0 interaction records on file.
How it works, mechanistically.
Core mechanism
Sea buckthorn oil supplies palmitoleic acid, linoleic acid, alpha-linolenic acid, oleic acid, tocopherols, carotenoids, and phytosterols. These lipids may support epithelial barrier function, mucosal hydration, and inflammatory balance in skin and urogenital tissues. Effects depend strongly on whether the product is seed oil, pulp oil, berry oil, or a mixed oil because fatty acid and carotenoid profiles differ.2,1
Dosing & protocol.
Take with meals to improve tolerability and absorption of fat-soluble carotenoids and tocopherols.
What it actually costs.
Real-world pricing across three quality tiers. Assumes Mixed sea buckthorn oil softgel.
Pulp oils and products standardized to palmitoleic acid are usually more expensive. Updated 2026-06-04.

Side effects
- Fishy or oily burps
- Nausea
- Loose stools
- Orange discoloration of stool or skin with high carotenoid intake
- Allergic reaction
- Possible increased bleeding tendency in susceptible users
