Palmitoleic acid, or omega-7, is one of the least common fatty acids in a typical diet, yet it plays an essential role in maintaining the integrity of mucous membranes and the skin’s protective lipid barrier. By reinforcing this natural barrier, omega-7 helps preserve skin suppleness and limit feelings of dryness, whether ocular, oral or intimate.

Sea buckthorn oil stands out from other plant sources for its exceptional density of omega-7; unlike macadamia oil, it offers a full spectrum of unsaturated fatty acids and protective micronutrients. Standardised to over 30% omega-7 through the Omegia raw material, this formula is one of the most concentrated on the European market. Beyond hydration, omega-7 also supports healthy lipid metabolism, with several research studies suggesting a positive effect on insulin sensitivity markers and blood lipid profile, alongside a balanced diet and active lifestyle.

Regular use of sea buckthorn oil supports people prone to chronic skin dryness, tightness or age-related loss of elasticity; omega-7 fatty acids, combined with vitamin E and beta-carotene, help regenerate epithelial tissue and protect cells against oxidative stress, for a more even complexion and deeper nourishment.

Mucous membranes are another key area of action: during menopause, many women experience intimate discomfort linked to reduced natural lubrication, and studies on sea buckthorn oil show a significant improvement in vaginal mucosa hydration after eight to twelve weeks of supplementation, without hormones. Eye comfort can also benefit — people who spend long hours in front of screens, in air conditioning or wind often notice less stinging and dryness, as omega-7 supports the stability of the tear film.

Take 1 to 4 capsules a day with meals. For general skin and mucous membrane support, 1-2 capsules is enough; for pronounced dryness (ocular, intimate or cutaneous), 3-4 capsules daily is preferable. First results are usually noticeable after four weeks of regular use, and a three-month course is recommended for lasting effect. The tapioca capsule is easy to take with a glass of water, with no aftertaste.

Not recommended for people on anticoagulant treatment or who smoke. Pregnant or breastfeeding women should seek medical advice before supplementing. Suitable for adults and children from age 3 able to swallow a capsule. Do not exceed the recommended daily dose. Store in a cool, dry place away from light. Keep out of reach of young children. A food supplement does not replace a varied, balanced diet or a healthy lifestyle.

Is omega-7 suitable for vegetarians?

Yes, this formula is 100% plant-based. The capsules are made from tapioca and plant glycerine, with no animal gelatine. The Omegia sea buckthorn oil is itself organic-certified and contains no animal-derived ingredients, making this supplement fully suitable for vegetarian and vegan diets.

How long before I feel the effects of sea buckthorn oil?

The first results on skin hydration and mucous membrane comfort generally appear after four to six weeks of daily use. For optimal effect on ocular or intimate dryness, a three-month course at 3-4 capsules a day is recommended; consistency of use is the key factor.

Can omega-7 be combined with other supplements?

Sea buckthorn oil combines well with other supplements. A common pairing is with omega-3 (EPA/DHA) for a full spectrum of essential fatty acids, or with vitamin C to boost antioxidant protection. If you take an anticoagulant, consult your doctor before combining supplements.
