One fruit. Three antioxidants.
RosaEx™ is an extract of Rosa roxburghii, a fruit native to southwest China that's been studied for decades for its antioxidant activity. It's an unusual source: vitamin C, SOD, and polyphenols in a single fruit, standardized to SOD activity above 10,000 IU.
That's a real antioxidant story for beauty-from-within and clean-label wellness formulas.
Delivering an antioxidant is one thing. Helping skin use it is another.
RosaEx™ does both, backed by in vitro research on the extract and decades of human research on the fruit it comes from.
Rosa roxburghii has been researched in humans for its support of SOD activity, the enzyme the body uses to neutralize free radicals. NuLiv Science built RosaEx™ on that foundation and standardized it to SOD activity above 10,000 IU, a reliable dose of what makes the fruit so effective.
In vitro research on RosaEx™ showed an increase in vitamin C uptake and transporter activity in skin cells under oxidative stress. Source plus utilization, in the same ingredient. Most antioxidants don't tell that story.
In an in vitro oxidative stress model, RosaEx™ supported Pro-Collagen III versus the stressed control, and outperformed vitamin C alone, despite containing less total vitamin C. For ingestible beauty formulas built around collagen, that's a difference worth talking about.
Where RosaEx™ earns its place.
A single-fruit antioxidant extract for healthy aging formulas, multivitamins, and antioxidant blends where botanical heritage and a clean label tell the story better than synthetic options.
RosaEx™ delivers vitamin C and helps skin cells use it, pairing naturally with Astrion® for a full skin health stack where one ingredient handles collagen and hydration and the other handles antioxidant support and utilization.
