Trans Resveratrol 50% (Polygonum cuspidatum Sieb) (root) {Granular}

Trans Resveratrol 50% is a highly sought-after phytochemical derived primarily from the root of Polygonum cuspidatum Sieb, commonly known as Japanese Knotweed. This granular extract is standardized to contain a minimum of 50% trans-resveratrol, the biologically active and most extensively studied isomer of resveratrol. While resveratrol is naturally found in grape skins, red wine, and certain berries, Japanese Knotweed provides a concentrated and reliable botanical source, valued for its robust phytochemical profile. In traditional Asian medicine, *Polygonum cuspidatum* has been utilized for centuries for its diverse health-supporting properties, particularly for cardiovascular and inflammatory conditions, underscoring its historical significance and broad therapeutic potential. The granular form of this extract ensures ease of handling and incorporation into various supplement formulations, offering excellent flow characteristics and blend uniformity, which are critical for manufacturing efficiency and product consistency.

The profound health benefits of trans-resveratrol are largely attributed to its potent antioxidant and anti-inflammatory properties. Research indicates its ability to scavenge free radicals, thereby mitigating oxidative stress, a primary contributor to cellular aging and various chronic diseases. Furthermore, trans-resveratrol has been shown to modulate key cellular pathways, including the activation of sirtuins (specifically SIRT1), which are proteins linked to cellular longevity and metabolic regulation. Studies published in journals like *Nature* and *Cell Metabolism* have explored its role in mimicking caloric restriction, influencing mitochondrial function, and supporting healthy endothelial function, which is crucial for cardiovascular well-being. Its anti-inflammatory actions involve the inhibition of pro-inflammatory enzymes like COX-1 and COX-2, as well as the modulation of NF-κB signaling, contributing to a balanced inflammatory response throughout the body.

Trans Resveratrol 50% is a versatile ingredient for a wide array of supplement formulations, including those targeting anti-aging, cardiovascular support, cognitive function, and metabolic health. Its inclusion in formulas often aims to leverage its cellular protective and longevity-promoting effects. Quality assurance is paramount, requiring rigorous testing for purity, potency, and the absence of contaminants such as heavy metals and pesticides, ensuring a safe and effective product. Scientific evidence continues to accumulate, with numerous preclinical and clinical studies investigating trans-resveratrol's impact on human health. For instance, research has explored its potential benefits in supporting healthy blood lipid profiles and glucose metabolism, further solidifying its role in comprehensive wellness strategies. Formulators often combine it with bioavailability enhancers like piperine to optimize absorption and maximize its therapeutic potential in finished products.
