By Dr. Raj Dhadwal
The colour of sea buckthorn, and seabuckthorn, the deep orange-red that gives the whole berry its look, is not decoration. It comes from carotenoids, the same broad family of plant pigments behind carrots and pumpkin, and it travels through the fruit alongside tocopherols, the vitamin E family, both concentrated in the oil that sits inside the berry's pulp and skin.
Sea buckthorn's colour comes from carotenoids and its oil carries tocopherols, two naturally occurring compound families that travel together in the whole, unfiltered berry.
What do carotenoids and tocopherols actually do in the body?
Carotenoids and tocopherols are both fat-soluble, meaning the body absorbs them alongside dietary fat rather than water, which is one reason a whole berry with its natural oil intact behaves differently from a stripped, watery juice. The body's antioxidant network draws on a wide range of these compounds continuously; nutrition supplies the raw material, the body does the regulating.
Why are carotenoids and tocopherols concentrated where they are in the fruit?
Both compound families are fat-soluble, so they concentrate in the parts of the berry that carry oil, the pulp and the skin, rather than in the watery fraction. That is the same reason a whole, unfiltered purée keeps a fuller carotenoid and tocopherol profile than a clarified juice, which strains out pulp and skin to reach clarity.
What is actually inside a serving, proportionally?
A serving of whole sea buckthorn purée is mostly berry pulp and skin, with a meaningful share of naturally occurring pulp oil, the fraction that carries the carotenoids and tocopherols, and the water native to the fruit itself. Nothing added, nothing strained out.
The Human Renaissance claim
Human Renaissance is the only sea buckthorn purée in the world sold in a single-serve pouch. 190+ naturally occurring compounds, omega 3, 6, 7 and 9, 201 mg of vitamin C per pouch, 0 g sugar, 5,640 hand-picked berries per box.
What a serving is made of
Proportions are illustrative of whole-fruit composition, not a nutrition panel.
A 2017 review by Pullar, Carr and Vissers in Nutrients (PMC5579659) examined vitamin C's role in skin health, including how it works within the skin's broader antioxidant network alongside fat-soluble compounds like vitamin E and carotenoids. That research is specifically about vitamin C, not carotenoids or tocopherols directly, and it did not test sea buckthorn or any sea buckthorn product. We cite it here because it is honest, peer-reviewed context for how these antioxidant compound families interact in skin biology generally, not as evidence about sea buckthorn's carotenoid or tocopherol content specifically. That distinction matters more than the citation itself.

Where to find it
The colour and the oil are both still in the pouch. Human Renaissance sells whole sea buckthorn purée, skin, pulp and oil together, in single-serve 30 mL pouches. The full breakdown is on the sea buckthorn purée product page.
