Unique Properties
Patient One Arginine supplies 750mg of important amino acid nutrition to support a range of functions in the body. L-Arginine is most noted as a precursor to nitric oxide (NO), a vasodilator which promotes peak circulation and optimizes diverse aspects of circulatory-dependent wellness. Through this key role in NO production, Arginine supports heart health, blood vessel health, stamina, and healthy sexual function. L-Arginine is one of the two main amino acids that promote sperm motility.

As a precursor to creatine, Arginine is often used to support muscle function and peak athletic performance. It maintains epithelial integrity of the GI tract and skin, while enhancing collagen synthesis. Arginine is involved in protein synthesis, supporting cell division, wound healing, and tissue and bone repair. Further, Arginine plays a role in the synthesis of antibodies that support healthy immune response by promoting nitrogen retention and T-cell proliferation.


  • Medical researchers from the University of Tübingen’s Department of Surgery in Tübingen, Germany, found that “arginine supplementation can lead to normalization or improvement of healing” after conducting a research review into the role arginine plays in cellular physiology. Arginine’s role in tissue repair was found to be a “requirement, ” with researchers concluding that arginine’s ability to produce collagen is “an essential substrate for wound healing processes.”
  • The Graduate School of the Arts and Sciences Department of Life Sciences of the University of Tokyo in Japan conducted a 6-month long research study into the benefits of an amino acid dietary supplement containing arginine. Researchers discovered that long-distance runners taking the supplement daily demonstrated a significant improvement to their physical condition through increased cardiovascular health.
  • The Sinai Hospital of Baltimore’s Department of Surgery, in Baltimore, Maryland, researched the effects of arginine supplementation in the elderly for the purposes of determining the amino acid’s ability to promote healing. Thirty men and women over the age of 65 received arginine supplementation for 2 weeks, leading to a significant increase in wound closure. Researchers also discovered that arginine supplementation appeared to increased immune response in the elderly by stimulating T-cell function as well.
