L-Arginine

L‑Arginine – Targeted Amino Acid Support
Supports Heart Health, Circulation, and Immune Function

L‑Arginine is a clinically relevant amino acid formulated to support optimal cardiovascular function, immune health, and nitric oxide production. Arginine plays a central role in vascular integrity and blood pressure maintenance by serving as the direct precursor to nitric oxide—a key signaling molecule that helps relax blood vessels and promote healthy circulation.*

Although the body can synthesize arginine, certain conditions such as stress, intense physical activity, pregnancy, trauma, or surgical recovery may increase the need for this conditionally essential amino acid. Supplementation may help bridge nutritional gaps and support foundational systems involved in blood flow, immunity, and protein metabolism.*

Arginine also plays an important role in supporting the integrity of endothelial cells—the thin lining of blood vessels that regulates exchange between the bloodstream and surrounding tissues.*

Key Features*

• Hypoallergenic – Gluten-free, dairy-free, soy-free, and non-GMO

• Vegetarian-friendly formula

• High-potency dose delivering 750 mg of L-arginine per capsule

• Free from artificial ingredients and preservatives

L‑Arginine is ideal for individuals who:

• Are looking to support cardiovascular function and maintain healthy blood pressure*

• Need to promote healthy circulation and endothelial function*

• Require additional immune support during times of stress, exertion, or recovery*

• May have increased arginine demands due to strenuous exercise, pregnancy, or healing*

• Follow plant-based diets and may benefit from targeted amino acid supplementation

L‑Arginine may benefit:

Cardiovascular Support: Promotes nitric oxide production to help maintain healthy blood pressure and support blood vessel flexibility and tone.*
Circulatory Health: Supports normal blood flow and endothelial function, which is vital for nutrient delivery and vascular resilience.*
Immune Function: Plays a role in immune cell activity and helps maintain balanced immune responses.*
Muscle & Recovery: Aids protein synthesis and may help meet increased amino acid needs in periods of healing, exercise, or growth.*

Recommended Use: Take one (1) capsule daily or as directed by your healthcare practitioner.
