Resveratrol is a naturally occurring compound found in certain plants, most famously in red wine. Over the last decade, it has gained attention for its potential role in promoting longevity, supporting skin health, and reducing inflammation. But what does the science really say?
Red wine contains small amounts of resveratrol, mainly in the skins of red grapes. This antioxidant has been linked to heart health and the so-called “French paradox” — the observation that certain populations have relatively low rates of heart disease despite diets rich in saturated fats.
What Is Resveratrol?
Resveratrol is a polyphenolic antioxidant in the stilbenoid family. Plants produce it to defend against environmental stress. In humans, research has focused on its role in:
- Antioxidant support
- Anti-inflammatory pathways
- Cardiovascular health
- Skin vitality
- Cellular health & longevity
Resveratrol Benefits (Including Trans-Resveratrol)
1. Anti-Inflammatory & Antioxidant Support
Resveratrol may help reduce oxidative stress and support the body’s inflammatory response. Some studies have compared its pathway effects to certain NSAIDs, but it’s not a replacement for medical treatment.
If you're wondering what is the best anti-inflammatory medication, this depends on your condition and GP guidance. Resveratrol is a supportive nutrient, not a medicine.
2. Skin Health
Resveratrol benefits for skin include protection from UV damage, support for collagen production, and reduction of visible redness — making it popular in skincare and oral supplement routines.
3. Cardiovascular Function
Trans-resveratrol, the bioactive form, has been studied for its potential to support healthy blood flow, blood pressure, and endothelial function.
4. Longevity & Cellular Function
In lab studies, resveratrol activates sirtuins (SIRT1), proteins associated with ageing and metabolic regulation. While promising, human evidence is still developing.
Resveratrol Foods: Natural Sources
You can find resveratrol naturally in:
- Red grapes & grape juice
- Peanuts
- Blueberries
- Cranberries
- Dark chocolate
- Japanese knotweed (a common source of trans-resveratrol supplement ingredients)
Resveratrol Side Effects & Safety
Moderate doses are typically well tolerated. High doses (above 1 g/day) may cause:
- Digestive discomfort
- Interactions with blood thinners or NSAIDs
- Hormonal changes (seen in animal data)
Always consult your GP before starting any supplement — especially if you’re on medication.
Choosing the Best Resveratrol Supplement
Trans-Resveratrol vs Resveratrol
Trans-resveratrol is the most bioavailable and active form, making it the preferred choice in quality formulas.
What to Look For
When choosing the best resveratrol supplement or mega resveratrol, consider:
- 98 %+ trans-resveratrol purity
- Natural sourcing (e.g. Japanese knotweed)
- No artificial fillers
- Independent third-party testing
Resveratrol capsules are the most common format. In the UK, trans-resveratrol capsules UK products are easy to find — but quality matters.

Resveratrol UK: Regulations, Halal Status & Availability
In the UK, resveratrol is classed as a food supplement. This means it cannot legally be marketed to treat or cure diseases, but it can support general health and wellbeing.
When buying resveratrol UK supplements:
- Check MHRA / UK compliance
- Review the trans-resveratrol dosage per capsule
- Look for transparent labelling and halal suitability where relevant
- Confirm Halal status if this matters to you — resveratrol itself is a plant-derived compound (commonly from Japanese knotweed), which is naturally halal. However, the capsules and manufacturing process can vary, so check that the brand uses halal-certified capsules and avoids cross-contamination with haram ingredients such as gelatin from non-halal sources.
