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\n                    \u003c\/div\u003e\n                                                \u003cbr\u003e\n                \u003cdiv class=\"tag-container\"\u003e\n                                    \u003cimg src=\"https:\/\/www.powerbody.de\/skin\/frontend\/base\/default\/images\/tag\/gluten-free.png\" title=\"Gluten free\" alt=\"Gluten free\"\u003e\n                \u003cimg src=\"https:\/\/www.powerbody.de\/skin\/frontend\/base\/default\/images\/tag\/non-gmo.png\" title=\"Non-GMO\" alt=\"Non-GMO\"\u003e\n                \u003cimg src=\"https:\/\/www.powerbody.de\/skin\/frontend\/base\/default\/images\/tag\/vegan.png\" title=\"Vegan\" alt=\"Vegan\"\u003e\n                \u003cimg src=\"https:\/\/www.powerbody.de\/skin\/frontend\/base\/default\/images\/tag\/vegetarian.png\" title=\"Vegetarian\" alt=\"Vegetarian\"\u003e\n                \u003c\/div\u003e\n                        \u003c\/div\u003e\n    \u003cdiv id=\"ingredients-container\" class=\"product-description__ingredients ingredients-container-inner grouped-product  \"\u003e\n                    \u003ch2 class=\"product-description__header\"\u003eProduktetikett\u003c\/h2\u003e\n                        \u003cdiv class=\"ingredients-label-container\"\u003e\n                \u003cp\u003e\u003cstrong\u003eSupplement Facts:\u003c\/strong\u003e\u003cbr\u003eServing Size: 2 Tablets\u003cbr\u003eServing Per Container: 60\u003c\/p\u003e\n\u003cp\u003eAmount Per Serving:\u003cbr\u003eL-Arginine (as 500 mg immediate release and 500 mg sustained release from L-Arginine alpha-Keto-Glutarate) 1000mg\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eL-Arginine Other Ingredients:\u003c\/strong\u003e\u003cbr\u003eMicrocrystalline cellulose, stearic acid, silicon dioxide, magnesium stearate (vegetable source), croscarmellose sodium, hypromellose (coating).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eL-Arginine Recommended Use:\u003c\/strong\u003e\u003cbr\u003eAdult: Take 2 tablets daily, away from food, or as recommended by a nutritionally-informed physician.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWarnings:\u003cbr\u003e\u003c\/strong\u003eConsult your physician before using this product if you are pregnant, lactating, have a medical condition, on prescription medications, or other supplements that may lower blood pressure while taking in concomitant with this product.
