PREGNANCY:

INTERACTIONS:
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.
