The popularity of Resveratrol has led to a proliferation of products under various names and concentrations. For the consumer, differentiating between the essential active ingredient and general product offerings can be confusing.

The collective term resveratrol supplements covers a vast range of products, from single-ingredient capsules to complex blends featuring other longevity compounds. Regardless of the marketing, the quality of these products depends entirely on the presence of trans-resveratrol, the biologically active isomer. Supplement companies must be transparent about the percentage of trans-resveratrol in their products, as the cis-isomer offers negligible benefit.

For raw material buyers, the specification is usually a minimum of Resveratrol 98% purity, confirming the high purity Trans-Resveratrol content in the Resveratrol bulk powder. This material is sourced from a certified Resveratrol manufacturer and is utilized for both nutraceutical grade Resveratrol and cosmetic grade Resveratrol products. Products aimed at the NAD+ synergy, such as nad resveratrol blends, often use this high-grade powder. The Resveratrol B2B transactions require the Resveratrol distributor to provide the Resveratrol COA to ensure that the resveratrol supplements and final resveratrol 400 mg doses are correctly formulated.
