In athletes, standardised pine bark extract has improved fitness-test scores, triathlon times and muscle cramping. This guide explains how it works, the 8 sport and 8 health benefits, and where SCN\u2122 uses it.<\/p>\n<\/div>\n<div class=\"quick\"><b>Quick answer:<\/b> Pine bark extract benefits come from its proanthocyanidins: pine bark extract standardised to 95% proanthocyanidins supports nitric oxide synthesis and protects NO from oxidative breakdown, improving blood flow and oxygen delivery; it also reduces exercise-induced oxidative stress and inflammation and supports cerebral circulation for focus. In a 2013 trial, recreational athletes and triathletes taking pine bark extract improved endurance performance and reported less cramping. SCN\u2122 includes 200 mg of 95% OPC maritime pine extract in <a href=\"https:\/\/www.s-c-nutrition.com\/product\/endurance-power-vo2-max-supplement\/\" data-wpel-link=\"external\" rel=\"noopener\">Krebs Cycle Accelerator\u2074\u2070<\/a>.<\/div>\n<h2>What is pine bark extract?<\/h2>\n<p>Pine bark extract is made from the bark of maritime pine (<em>Pinus pinaster<\/em>, grown on the Atlantic coast of France) or its Asian relative <em>Pinus massoniana<\/em>. The bark is extracted and standardised to its <strong>procyanidins \/ proanthocyanidins<\/strong> (OPCs) \u2014 oligomers of catechin and epicatechin \u2014 plus phenolic acids such as ferulic and caffeic acid and the flavonoid taxifolin. The best-known branded form is Pycnogenol\u00ae; SCN\u2122 uses a maritime pine extract standardised to 95% proanthocyanidins (190 mg OPC per 200 mg), a higher standardisation than most commercial extracts.<\/p>\n<h2>How does pine bark extract work?<\/h2>\n<div class=\"cards\">\n<div>\n<h4>1 \u00b7 Nitric oxide support<\/h4>\n<p>OPCs activate endothelial nitric oxide synthase (eNOS) and, crucially, scavenge the superoxide radical that otherwise destroys NO within milliseconds \u2014 so the NO your nitrate and citrulline produce lasts longer.<\/p>\n<\/div>\n<div>\n<h4>2 \u00b7 Potent antioxidant<\/h4>\n<p>Pine bark OPCs neutralise reactive oxygen species and regenerate vitamins C and E, protecting membranes, mitochondria and DNA during intense exercise.<\/p>\n<\/div>\n<div>\n<h4>3 \u00b7 Anti-inflammatory<\/h4>\n<p>Inhibits NF-\u03baB signalling and reduces circulating inflammatory markers after exercise, supporting recovery.<\/p>\n<\/div>\n<div>\n<h4>4 \u00b7 Vascular integrity<\/h4>\n<p>OPCs bind to collagen and elastin in vessel walls, improving capillary strength and microcirculation.<\/p>\n<\/div>\n<\/div>\n<h2>What are the 8 sport benefits of pine bark extract?
