Sea Buckthorn Oil (96%) Dietary Supplement

Your Organic Sea Buckthorn Oil – Vitamin D3 dietary supplement: The Immunity Boost

L’Invincible is a plant-based dietary supplement designed to support the body during times when it needs extra help. Its effectiveness lies in a simple combination:

• Sea buckthorn oil rich in omega-7,
• plant-based vitamin D3 derived from lichen
• antioxidant vitamin E.

A concentrated, balanced formula designed to act directly on barrier tissues—immune cells, mucous membranes, skin, and lipid membranes.

With its easy-to-dose, highly bioavailable spray format, L’Invincible offers a unique plant-based alternative to traditional capsules. It’s a simple way to support your body’s natural defenses and help it stay resilient in the face of external stressors.

Sea Buckthorn Oil as a dietary supplement

Sea buckthorn berries are a rare fruit packed with remarkable energy. They grow in the harshest environments: the Alps, Tibet, and the cold shores of the Baltic Sea. This natural resilience is reflected in the exceptional composition of their oils.

Sea buckthorn berries are among the most nutritious fruits in the plant kingdom. Their vitamin C content can reach 450 mg per 100 g, and exceed 1,500 mg in certain high-altitude areas. This is one of the highest concentrations found in any fruit.

The oil’s intense color comes from carotenoids, which are present in exceptional quantities: the pulp can contain up to ten times more beta-carotene than a carrot. This high pigment concentration reflects remarkable natural antioxidant activity.

In a dietary supplement, this plant-based richness provides a comprehensive solution to seasonal needs. Renowned for its nutritional power, sea buckthorn oil has been used for centuries in many countries to support immunity. While in France it was customary to consume cod liver oil, Scandinavians preferred local sea buckthorn oil: Long before it captured the interest of scientists, it was part of the dietary culture of regions exposed to wind and cold.

In fact, there are several anecdotes that attest to his reputation:

• Chinese athletes used it as an "approved stimulant,"
• Russian and Mongolian cosmonauts tested it in flight,
• The Red Army requisitioned entire harvests to support the soldiers,
• After the Chernobyl disaster, sea buckthorn was used to soothe the skin and support weakened immune systems.

This age-old choice made by northern countries is now backed by modern science. The complete lipid profile of sea buckthorn oil— omega-3, omega-6, omega-7, and omega-9 —makes it a particularly valuable plant-based ingredient for immune-boosting dietary supplements.

Omega-3 and omega-6 fatty acids thus contribute to the body’s overall balance. Omega-7 fatty acids support inflammation management, and omega-9 fatty acids support membrane flexibility. This powerful synergy helps to:

• the stability of cell membranes, which is essential for immune function;
• comfort for mucous membranes exposed to cold and environmental stress;
• the skin barrier, the body’s first line of defense.

Today, scientific literature explains what fascinated our ancestors: exceptional nutritional density, high bioavailability, and a key role in cellular balance.

La Maison de l’Argousier grows its own sea buckthorn and uses an enzymatic extraction process certified organic and COSMOS. This gentle technique preserves fatty acids, fat-soluble vitamins, and antioxidants without the use of solvents. The result: a stable, pure oil rich in active ingredients, ideal for use in simple yet effective formulations.

Vitamin D3: Essential for Immunity

Derived from lichen, plant-based vitamin D3 supports the normal functioning of the immune system by acting on the cells involved in the body’s natural immune response. This fat-soluble vitamin influences antimicrobial peptide levels and helps maintain the balance of the body’s first-line defenses. Each spray of L’Invincible provides 200 IU, or 100% of the Reference Intake, in a bioavailable and easily absorbed form. Combined with the essential fatty acids and antioxidants in sea buckthorn oil, it supports a comprehensive nutritional approach to help you get through periods of fatigue, cold weather, or reduced sunlight.

Vitamin E

Vitamin E is an essential fat-soluble antioxidant known for its role in protecting membrane lipids. It neutralizes free radicals generated by oxidative stress. It also preserves the integrity of cells exposed to temperature fluctuations or external stressors. In the dietary supplement L’Invincible, it naturally stabilizes the formula rich in fatty acids and works in synergy with the carotenoids in sea buckthorn oil. Together, these plant-based antioxidants support membrane health, a key factor for tissue vitality and the body’s overall balance during cold weather.

The effectiveness of the sea buckthorn oil and vitamin D3 combination

The combination of an oil rich in bioactive fatty acids and plant-based vitamin D3 provides a comprehensive approach to supporting immunity:

• Vitamin D3 influences the expression of antimicrobial peptides;
• Fatty acids help maintain the fluidity and strength of cell membranes;
• plant carotenoids contribute to antioxidant protection;
• Omega-7 plays a role in managing inflammation.
