What Is Trans-Resveratrol and Why Does It Matter?

Trans-resveratrol (trans-3,5,4'-trihydroxystilbene) is the biologically active isomer of resveratrol, the form that has been identified by pharmaceutical and nutraceutical researchers for its antioxidant, cardioprotective and metabolic health effects.

Resveratrol is a natural defence molecule produced by plants to protect them from bacterial or fungal invasion. Available in concentrated, standardised powder form, it provides formulators with exact dosage control that raw botanical sources just can’t match.

It has a molecular weight of 228.24 g/mol, melting at 253–255°C. It is very thermostable under anaerobic conditions yet lipophilic and poorly water soluble, and this is a formulation concern worth preparing for.

Application Scenarios for B2B Formulators

Formulating is an art and a science, says this ingredient, which plays in multiple high-value sectors. “Knowing where you fit helps you formulate better.”

Dietary Supplements (Cardiovascular Health & Longevity)

Trans-resveratrol is a major active compound in anti-aging and heart health stacks, commonly coupled with NMN or NR. It is usually made into softgels with lipid carriers (such as olive or grapeseed oil) to enhance lymphatic uptake (for optimum absorption).

Cosmeceuticals (Advanced Skin Care)

It is a tyrosinase inhibitor that supports skin whitening and increases collagen formation in night creams and serums. It is strongly suggested to utilise vacuum sealed or airless pump packaging for completed products due to oxidation of the powder upon contact with air and light.

Functional Food & Beverages

Microencapsulation is suggested for application in energy bars and functional drinks. It conceals the natural bitterness and preserves the active substance from deterioration during pasteurisation or long shelf storage.

Your choice of purity grade and carrier system will be dependent on your desired application and our technical staff is on hand to assist you with your formulation choices.

Storage and Handling Guidelines

Proper storage directly affects the efficacy of your resveratrol ingredient.

Store in a cool, dry and well-ventilated environment away from direct sunlight and UV exposure.
Store away from strong oxidising chemicals and dampness.
Recommended storage temperature < 25 °C.
After opening, reseal packaging carefully and use as soon as possible to minimise oxidation.
Shelf life is normally 24 months under optimal circumstances in original sealed packaging.

It is recommended to work in low-oxygen conditions for high-purity grades, notably >=98% standards.

Packing and Delivery

Standard packing is 25kg per drum, using vacuum composite film or nitrogen-filled aluminium foil bags within the drum to avoid moisture and oxidation.

We offer customised packaging choices, including light-resistant bottles, reduced batch sizes for sample orders, and multilingual labelling for different regional markets.

Stock on hand so fast despatch is assured. Delivery: Delivery is made within 2-3 working days following order confirmation. Depending on your volume and timetable we offer shipping via courier, air freight or ocean freight.
