Resveratrol – The Vitality Powerhouse

Resveratrol serves as a potent antioxidant, combating unstable molecules known as free radicals. These radicals may stem from routine bodily processes and/or exposure to environmental factors, leading to oxidative stress, a primary cause of many visible signs of aging.

We often think of Resveratrol as a "red wine extract," but this is a lower-quality form. Trans-Resveratrol is easier for the body to use, making it the superior form. The purest source of trans-Resveratrol is found in the root system of Japanese knotweed, categorized as one of the most invasive species of plants on Earth.

The Prominent Difference

Our supplement is standardized to 98% trans-Resveratrol

- This level of purity ensures the highest quality.

We source our Resveratrol from Japanese knotweed

- Japanese knotweed roots are the best source for trans-Resveratrol. This is the bioactive form of Resveratrol, meaning the body absorbs and uses it more easily.

Our Resveratrol’s potency is tested using High-performance Liquid Chromatography (HPLC)

- HPLC is the best way to quantify trans-Resveratrol potency, thanks to its accuracy.

Why Not Use Red Wine Extract?

At our core, we prioritize delivering the highest quality Resveratrol to you. While red wine grapes offer some Resveratrol, their potency is limited.

Many "red wine extract" products contain grape skins treated with fungicides, compromising the purity of the Resveratrol. While it would be possible to source clean red wine extract, we opt for a superior alternative.

The potency concern lies with the type of Resveratrol present in grapes, primarily cis-Resveratrol, which is less bioactive. In contrast, our supplement harnesses trans-Resveratrol sourced from Japanese knotweed, ensuring optimal bioactivity for your health. For us, the choice is evident—prioritizing your well-being above all else.

Frequently Asked Questions

Why do you specifically use a root extract?
There is Resveratrol present in other parts of the Japanese knotweed plant, but the roots are by far the most concentrated source of the more bioactive trans-Resveratrol form.

With all our herbal supplements, we look for the ingredient source with the highest concentration of the desired ingredient as well as the optimal molecular form of that active.
How is your Resveratrol tested?
We have a trusted third-party lab to test for trans-Resveratrol potency using an HPLC method. HPLC is the most accurate and discerning analysis method. Other test methods are cheaper but give a blurred picture of the compounds in the final product.
Why isn’t your Resveratrol organic?
At Prominent Nutrition, we follow the science. Many members of our team eat organic foods and appreciate the growing public interest in choosing to eat better.

Whenever scientific studies show better health outcomes for organic versus non-GMO ingredients, we choose the organic option. If a particular supplement of ours is not certified organic, that means our scientific team has not found sufficient data to support an organic choice. Rest assured that the ingredient source we’ve selected is optimized for your health first and foremost.
How soon does Resveratrol provide effects?
Antioxidants work immediately at a molecular level. It takes time for all those micro-effects to amplify into health benefits you can feel. Some people experience effects from Resveratrol within a week. Most take longer, with the greatest benefits coming after months of consistent use. Our Resveratrol is formulated specifically for safe, long-term use.*
