Sustained Release Arginine is a dietary supplement that provides a sustained-released form of L-Arginine, an amino acid that is important for maintaining cardiovascular health and supporting various metabolic functions in the body.*

This product is perfect for adults interested in promoting their cardiovascular health, maintaining healthy blood pressure levels already within the normal range, or enhancing overall wellness and athletic performance.

As a dietary supplement for adults, take three (3) tablets twice daily, preferably with meals, or as directed by your healthcare practitioner. It is normal for this product to have a distinctive botanical aroma.

In addition to its primary cardiovascular benefits, L-Arginine may also support immune health, help in detoxification, aid in protein synthesis, and play a role in hormone regulation and male fertility.*

Sustained Release Arginine contains L-Arginine, a semi-essential amino acid known for its involvement in multiple metabolic pathways, particularly its role as a precursor to nitric oxide (NO), a key signaling molecule in the cardiovascular system. Adequate levels of L-Arginine are necessary for the production of NO, which promotes vasodilation and helps maintain blood flow and vascular tone (1). The sustained-release formulation is designed to release L-Arginine gradually over 4 to 6 hours, helping to ensure optimal absorption and plasma levels, which is crucial during periods of metabolic stress. Clinical studies have demonstrated that L-Arginine supplementation may support the maintenance of blood pressure in the normal range and promote healthy endothelial function, which supports overall cardiovascular health (2). Furthermore, L-Arginine is also critical in protein synthesis, immune modulation, and hormone regulation, making it an essential component for overall health (3).*
