📋 Food Supplement: Trans-Resveratrol Powder is a food supplement — not a medicine. Not intended to diagnose, treat, cure or prevent any disease or medical condition.

⚠️ Why Does This Product Have No Authorised Health Claims?
No authorised claims does not mean no research. It means the regulatory process hasn't caught up.
The GB NHC Register only lists claims formally approved following a submission to the relevant regulatory authority. A single health claim application requires an extensive clinical dossier, significant legal and scientific resource, and can take 5–10+ years to process — at a cost that is prohibitive for most botanical and novel compounds. Resveratrol has substantial peer-reviewed scientific literature but has never had a claim submitted, simply because no commercial entity has the incentive to fund a regulatory process whose outcome benefits the entire market.

Resveratrol was first identified in 1939 and has been studied since, with over 2,000 published papers examining its properties. EFSA itself has reviewed resveratrol's safety profile without approving a corresponding health claim.
We cannot make health claims for this product under UK law. All content on this page is provided as educational background only. We encourage you to review the published research independently and consult your GP before starting any new supplement. Food supplement — not a medicine.
⚠️ Advisory: Consult your GP before use if taking anticoagulants (warfarin) or hormone-related medications — resveratrol may interact with these. Resveratrol has poor oral bioavailability (typically less than 1%) — this is an honest characteristic of the compound, not a quality issue with this product. Higher doses (1,000mg+ daily, long-term) have been associated with mild digestive symptoms in some studies. Not recommended during pregnancy or breastfeeding. Food supplement — not a medicine.

Resveratrol (3,5,4′-trihydroxy-trans-stilbene) is a polyphenolic compound classified as a stilbenoid, naturally found in the skin of grapes, certain berries and peanuts. Trans-resveratrol is the biologically active isomeric form — the form used in this powder. Resveratrol is produced by plants as a phytoalexin, a natural defence compound synthesised in response to fungal attack, UV exposure or physical stress. It has been studied scientifically since 1939, when it was first identified, with over 2,000 published research papers examining its properties. Educational background only — food supplement, not a medicine.
At 99% purity, this is a high-strength powder — meaning 99% of the powder by weight is trans-resveratrol, with less than 1% other substances. No fillers. Supplied in a branded, food-certified resealable foil pouch to protect the compound from light and moisture — resveratrol is sensitive to environmental degradation and benefits from proper storage. Food supplement — not a medicine.
🔬 Trans-Resveratrol — Educational Background
🍇 Grape-Derived vs Japanese Knotweed — Sourcing Transparency
Most commercial trans-resveratrol on the UK market is extracted from Japanese knotweed (Polygonum cuspidatum) — a fast-growing invasive plant that yields higher resveratrol concentrations at lower production cost. Our trans-resveratrol is sourced from grape skin extract (Vitis vinifera) instead — the traditional dietary source most commonly associated with resveratrol, and the source used in much of the foundational research linking resveratrol to red wine and grape consumption. Both sources can yield high-purity trans-resveratrol — the resveratrol molecule itself is chemically identical regardless of plant origin. This is a sourcing transparency choice, not a purity claim — always check the declared plant source on any resveratrol product label, as it is rarely volunteered. Educational background only — food supplement, not a medicine.
📊 What the Research Shows — Honestly
Resveratrol has been extensively researched in laboratory and early-stage clinical settings — examined for potential relevance to cardiovascular health, antioxidant activity, neurodegeneration and inflammation in academic literature. However, the evidence in humans remains limited. Wikipedia's review of the literature states there is "no high-quality evidence that resveratrol improves lifespan or has a substantial positive effect on any human disease." WebMD (medically reviewed July 2025) states resveratrol's "effects are not well defined." A critical limitation is oral bioavailability — typically less than 1% — due to extensive first-pass metabolism in the intestinal wall and liver, where resveratrol undergoes rapid glucuronidation and sulphation. Peak plasma concentrations occur within 30–60 minutes, but the parent compound is largely converted to metabolites. These are academic findings — not health claims for this food supplement. No authorised EU/UK claims for Resveratrol. Educational background only — food supplement, not a medicine.
🌿 What's in Grape Skin Extract
Grape skin (Vitis vinifera) is particularly rich in resveratrol compared to other parts of the grape — research comparing grape components has found red grape skin extract to be richer in phenolic content and resveratrol than grape seeds. Red wine's well-known association with resveratrol stems from the fermentation process — red wine is fermented with the grape skins in contact, allowing extraction of resveratrol into the wine, whereas white wine is typically fermented after the skins have been removed. A standard glass of red wine contains only around 1mg of resveratrol — far below the levels used in concentrated supplements like this powder.

❓ Frequently Asked Questions
What is Trans-Resveratrol Powder?
99% pure trans-resveratrol by Charge Products (Big Idea Services Ltd, Co. No. 11645389) sourced from grape skin extract (Vitis vinifera) — not Japanese knotweed. No fillers. Resealable foil pouch. In-house manufactured at our 5 Star FSA rated Essex facility. No authorised EU/UK health claims for Resveratrol. Educational background only. Food supplement — not a medicine.
Why grape-derived resveratrol instead of Japanese knotweed?
Most commercial trans-resveratrol comes from Japanese knotweed due to higher yield and lower cost. We source from grape skin extract instead — the traditional dietary source of resveratrol. Both can produce high-purity trans-resveratrol; the molecule itself is identical regardless of source. This is a sourcing transparency choice. Always check the declared source on resveratrol products, as it's rarely volunteered. Educational background only — food supplement, not a medicine.
