    5-methyltetrahydrofolate (5-MTHF) supplementation is not recommended concurrent with methotrexate cancer therapy, as it can interfere with methotrexate's anti-neoplastic activity; however, this folate source has not been shown to interfere with the anti-inflammatory activity of methotrexate. An individual taking methotrexate for psoriasis or rheumatoid arthritis can safely take a supplement containing folate.

    Individuals with a known herpes infection should not take L-arginine without also taking lysine, as L-arginine alone has been noted to cause herpes eruptions in susceptible individuals. L-arginine supplementation is contraindicated in a patient with hepatocellular carcinoma.

    More Info.

    L-arginine is a conditionally essential amino acid, meaning that while your body can make it, it becomes necessary to get it in through diet or supplementation under certain circumstances or for certain physical conditions. L-arginine, like other amino acids, is a building block of protein, which helps to promote muscle and tissue healing, helps to support a healthy immune system, and benefits cellular metabolism.

    One of L-arginine’s unique functions is that it is necessary for the production of nitric oxide. Nitric oxide is essential to the regulation of blood blow in the body. By supporting nitic oxide levels, L-arginine can support cardiovascular health, benefit healthy blood pressure, and optimize blood flow to the extremities.

    Thorne’s L-Arginine Plus combines L-arginine with Thorne's Time-Sorb® complex to help maintain an optimal levels of L-arginine over 24 hours with suggested use.
