L-arginine has been shown to support the cardiovascular system, through its conversion to nitric oxide. Research suggests L-arginine supplementation may also have positive benefits on athletic performance. Two tablets of Doctor's Best Sustained Plus Immediate Release Arginine delivers 1000mg L-arginine in a bilayer tablet, with two tablets providing 500 mg of sustained release and 500 mg of immediate release L-arginine. This technology allows for enhanced blood levels of L-Arginine for a continuous period of up to 8 hours.\u003c\/p\u003e\n\u003cp\u003eHow does it work?\u003cbr\u003eOral L-arginine supplementation has been shown in clinical studies to support various aspects of cardiovascular health. A randomized double-blind placebo-controlled trial found that six weeks of L-arginine supplementation enhanced circulation and supported healthy heart function compared to placebo. The L-arginine effect was due to its role in NO production. Other clinical trials have shown that oral L-arginine supplementation contributes to enhanced exercise tolerance because of its ability to enhance cardiac circulation and vasodilation of blood vessels. L-arginine enrichment of the diet in healthy individuals was shown to support blood pressure already in the normal range. The overall results of these and other clinical trials showed that long-term administration of this amino acid significantly enhanced endothelial function.\u003c\/p\u003e\n\u003cp\u003eWhy take Sustained and Immediate Release Arginine?\u003cbr\u003eThe normal aging process in humans has been found to be associated with progressive changes in endothelial function (cells that line the inner surfaces of blood vessels). Research suggests that a major reason for these common changes associated with aging is reduced production or bioavailability of nitric oxide (NO) in vessels and tissues. L-arginine is a substrate for the enzyme nitric oxide synthase, required for the production of nitric oxide in the body. Nitric oxide is a substance critical for the maintenance of normal vascular function. NO mediates a number of physiological effects on the cardiovascular system, including supporting healthy endothelial function, enhancing cardiovascular health and displaying potent antioxidant properties against free radicals.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e \u003cdiv class=\"facts-container\"\u003e\u003c\/div\u003e\n\u003cbr\u003e\u003cdiv class=\"tag-container\"\u003e\n\u003cimg alt=\"Gluten free\" data-pagespeed-url-hash=\"1810919066\" onload=\"pagespeed.CriticalImages.checkImageForCriticality(this);\" src=\"https:\/\/www.powerbody.eu\/skin\/frontend\/base\/default\/images\/tag\/gluten-free.png\" title=\"Gluten free\"\u003e\u003cimg alt=\"Non-GMO\" data-pagespeed-url-hash=\"204748423\" onload=\"pagespeed.CriticalImages.checkImageForCriticality(this);\" src=\"https:\/\/www.powerbody.eu\/skin\/frontend\/base\/default\/images\/tag\/non-gmo.png\" title=\"Non-GMO\"\u003e\u003cimg alt=\"Vegan\" data-pagespeed-url-hash=\"2948913791\" onload=\"pagespeed.CriticalImages.checkImageForCriticality(this);\" src=\"https:\/\/www.powerbody.eu\/skin\/frontend\/base\/default\/images\/tag\/vegan.png\" title=\"Vegan\"\u003e\u003cimg alt=\"Vegetarian\" data-pagespeed-url-hash=\"1947787142\" onload=\"pagespeed.CriticalImages.checkImageForCriticality(this);\" src=\"https:\/\/www.powerbody.eu\/skin\/frontend\/base\/default\/images\/tag\/vegetarian.png\" title=\"Vegetarian\"\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\u003cdiv class=\"product-description__ingredients ingredients-container-inner grouped-product content-description\" id=\"ingredients-container\"\u003e\n\u003ch2 class=\"product-description__header\"\u003eWhat is In\u003c\/h2\u003e\n\u003cdiv class=\"ingredients-label-container\"\u003e\u003cdiv class=\"label-page\" style=\"box-sizing: border-box; margin: 0; page-break-after: always;\"\u003e\n\u003cdiv class=\"label-block header\" style=\"box-sizing: border-box; margin-top: 0;\"\u003e\n\u003cdiv class=\"manufacturer-name bold-item\" style=\"box-sizing: border-box; font-weight: 900; margin-top: 0;\"\u003eDoctor's Best\u003c\/div\u003e\n\u003cdiv class=\"product-name bold-item\" style=\"box-sizing: border-box; font-weight: 900;\"\u003eL-Arginine - Sustained + Immediate Release, 500mg - 120 tablets\u003c\/div\u003e\n\u003cdiv class=\"product-descriptive_name\" style=\"box-sizing: border-box;\"\u003eFood supplement in tablet form, containing L-Arginine and minerals\u003c\/div\u003e\n\u003cdiv class=\"header-servings\" style=\"box-sizing: border-box; margin-top: 5pt; margin-bottom: 0;\"\u003e\n\u003cdiv class=\"header-nutrition-facts bold-item\" style=\"box-sizing: border-box; font-weight: 900;\"\u003eNutrition Facts\u003c\/div\u003e\n\u003cdiv class=\"header-serving-size\" style=\"box-sizing: border-box;\"\u003e\n\u003cstrong style=\"box-sizing: border-box; font-weight: 900;\"\u003eServing Size:\u003c\/strong\u003e 2 Tablets\u003c\/div\u003e\n\u003cdiv class=\"header-serving-size\" style=\"box-sizing: border-box;\"\u003e\n\u003cstrong style=\"box-sizing: border-box; font-weight: 900;\"\u003eServings Per Container:\u003c\/strong\u003e 60\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"label-block ingredients-list\" style=\"box-sizing: border-box; margin-top: 5px;\"\u003e\n\u003ctable style=\"box-sizing: border-box; width: 100%; border-spacing: 0px; margin-top: 0;\"\u003e\u003ctbody\u003e\n\u003ctr style=\"box-sizing: border-box;\"\u003e\n\u003cth style=\"box-sizing: border-box; text-align: left; font-weight: normal;\"\u003e \u003c\/th\u003e\n\u003cth style=\"box-sizing: border-box; text-align: left; font-weight: normal;\"\u003eAmount\u003cbr style=\"box-sizing: border-box;\"\u003ePer Serving\u003c\/th\u003e\n\u003cth style=\"box-sizing: border-box; text-align: left; font-weight: normal;\"\u003e%RI*\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"ingredient\" style=\"box-sizing: border-box;\"\u003e\n\u003ctd class=\"ingredient-name\" style=\"box-sizing: border-box;\"\u003eL-Arginine (as 500 mg immediate release and 500 mg sustained release from L-Arginine alpha-Keto-Glutarate)\u003c\/td\u003e\n\u003ctd class=\"weight\" style=\"box-sizing: border-box;\"\u003e1000 mg\u003c\/td\u003e\n\u003ctd class=\"rda\" style=\"box-sizing: border-box;\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003cp style=\"box-sizing: border-box; margin: 5px 0 0; margin-bottom: 0;\"\u003e\u003cspan class=\"daily-value\" style=\"box-sizing: border-box; display: block; padding: 0 5pt;\"\u003e*Percent Daily Values are based on a 2,000 calorie diet.
