Description

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 repair, 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.*

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.

What is L-arginine and what does it do in the body?

L-arginine is a conditionally essential amino acid, meaning your body produces it but may need extra support from diet or supplements in certain situations. It acts as a protein building block, supporting muscle and tissue repair, immune function, and cellular metabolism. It also plays a unique role in producing specific compounds your body needs for cardiovascular and performance-related functions.

Who should consider taking an L-arginine supplement?

L-arginine supplementation is popular among athletes, fitness enthusiasts, and people looking to support muscle recovery and immune health. It may also benefit individuals whose diets lack sufficient protein-rich foods. Those under physical stress, recovering from injury, or with increased training demands often find their natural L-arginine production insufficient, making supplementation a practical and effective solution.

When is the best time to take L-Arginine Plus?

Many users take L-arginine before workouts to support performance and circulation, or after exercise to aid muscle recovery. Some prefer taking it on an empty stomach for better absorption. Always follow the dosage instructions on the product label. Consistency matters most — taking it at the same time daily helps you experience the full benefits over time.

Are there any side effects associated with L-arginine supplements?

L-arginine is generally well-tolerated when taken as directed. Some individuals may experience mild digestive discomfort, especially at higher doses. People with certain medical conditions, those on medications, or pregnant and nursing women should consult a healthcare provider before starting any supplement. Starting with the recommended dose and assessing your body's response is always a smart approach.
