What’s Actually Inside

Every compound in sea buckthorn has been studied individually. Tap any nutrient below to see what the science says — and why your body is probably missing it.

C 15x oranges

Vitamin C

The immune architect your body can’t store

Why You Need It

Vitamin C is the most critical water-soluble antioxidant in human plasma. It’s essential for collagen synthesis (the structural protein in your skin, joints, and blood vessels), immune cell function, and iron absorption. Without adequate vitamin C, your body literally cannot build or repair tissue.

The Deficiency Problem

An estimated 46% of North American adults don’t get enough vitamin C from diet alone. Stress, smoking, pollution, and intense exercise all deplete it faster. Subclinical deficiency shows as slow wound healing, fatigue, weakened immunity, and accelerated skin aging.

What Research Shows

Sea buckthorn contains 600–1,300 mg of vitamin C per 100g — roughly 15x the concentration found in oranges. A 2017 review in Nutrients confirmed vitamin C’s critical role in both innate and adaptive immune function.

Ω7 < 3% of diets

Omega-7 (Palmitoleic Acid)

The rarest fatty acid most people have never heard of

Why You Need It

Omega-7 directly supports mucosal membranes throughout your body — skin, gut lining, eyes, and respiratory tract. Unlike omegas 3 and 6, omega-7 acts as a lipokine: a fat-derived hormone that signals between fat tissue and muscles, improving insulin sensitivity and reducing chronic inflammation.

The Deficiency Problem

Omega-7 is virtually absent from the modern Western diet. It exists in trace amounts in macadamia nuts and a handful of fish. When mucosal tissues degrade, you experience dry eyes, dry skin, gut permeability, and increased susceptibility to infection.

What Research Shows

A 2014 Cleveland Clinic trial demonstrated that purified palmitoleic acid reduced C-reactive protein (CRP) by 44% in just 30 days. Sea buckthorn is the richest known plant source, containing up to 40% palmitoleic acid in its fruit oil.

Ω Full spectrum

Omega 3, 6 & 9

The essential fats your brain and heart depend on

Why You Need It

Omega-3 (ALA) reduces systemic inflammation and supports brain function. Omega-6 is critical for skin barrier formation. Omega-9 supports cardiovascular health and fat-soluble vitamin absorption. The key is balance — and getting all three from whole-food sources.

The Deficiency Problem

The modern diet has an omega-6 to omega-3 ratio of roughly 20:1 instead of the optimal 2:1 to 4:1. This imbalance drives chronic inflammation, contributing to heart disease and metabolic dysfunction. Sea buckthorn naturally provides all three in a balanced profile.

What Research Shows

A comprehensive review confirmed that balanced omega intake reduces cardiovascular risk by up to 35%. Sea buckthorn seed oil contains ALA, linoleic acid, and oleic acid in a naturally balanced ratio — plus the rare omega-7 that no fish oil provides.

18 Amino Acids

The building blocks your body assembles everything from

Why You Need It

Amino acids are the literal building blocks of every protein in your body — from muscle tissue and enzymes to neurotransmitters like serotonin and dopamine. Sea buckthorn contains 18 amino acids, including all 9 essential ones your body cannot make.

The Deficiency Problem

Even in protein-sufficient diets, individual amino acid deficiencies are common. Lysine deficiency impairs collagen synthesis. Tryptophan deficiency reduces serotonin production, affecting mood and sleep. Plant-based diets are particularly vulnerable to incomplete profiles.

What Research Shows

Research demonstrated that amino acids regulate key metabolic pathways including immune response, gene expression, and antioxidant defense. Sea buckthorn’s profile shows significant concentrations of essential branched-chain amino acids critical for muscle recovery.

PP 60+ types

Polyphenols & Flavonoids

Nature’s cellular defense system

Why You Need It

Polyphenols act as your cells’ bodyguards against oxidative stress. They neutralize free radicals, reduce inflammation at the genetic level, and protect DNA from damage. Flavonoids like isorhamnetin, quercetin, and kaempferol — all abundant in sea buckthorn — have demonstrated anti-cancer and cardioprotective properties.

The Deficiency Problem

Most adults consume less than 1g of polyphenols daily, far below the 1.5–2g associated with disease prevention. Processing and cooking destroy polyphenols rapidly. The modern preference for refined foods means most people operate with minimal antioxidant defense.

What Research Shows

A landmark review established that dietary polyphenols reduce oxidative stress biomarkers by up to 30%. Sea buckthorn is exceptionally rich in isorhamnetin, which has shown specific anti-inflammatory activity by inhibiting TNF-α and IL-6 production.

E 8+ forms

Vitamin E & Carotenoids

The fat-soluble shield against aging

Why You Need It

Vitamin E is the body’s primary fat-soluble antioxidant, protecting cell membranes from oxidative damage. Sea buckthorn contains the full vitamin E family — tocopherols and tocotrienols. Its carotenoids (beta-carotene, lycopene, zeaxanthin) provide UV protection and support eye health.

The Deficiency Problem

Over 90% of Americans fail to meet the recommended intake of vitamin E. Low-fat diets, poor absorption, and limited dietary diversity all contribute. Carotenoid deficiency is similarly widespread, with most adults consuming fewer than 3 servings of carotenoid-rich produce per week.

What Research Shows

Research confirms that vitamin E reduces LDL oxidation and significantly improves skin photoprotection. Sea buckthorn oil contains 100–200 mg of tocopherols per 100g. Its carotenoid profile provides retinal protection against blue light damage.
