Description

Swanson Arginine Complex bonds arginine with silicate, unlocking powerful beneficial effects. It helps build nitric oxide levels over time to support healthy circulation and blood vessel integrity.

For over 15 years, the amino acid arginine has been widely researched as a supporting agent for cardiovascular wellness. Silicon is a well-established biological element recognized for its importance in connective tissue. Arginine Complex provides the benefits of both, along with additional benefits from the unique combination.

Arginine is converted in the body to nitric oxide which causes blood vessels to dilate or expand, to allow for optimal blood flow through the circulatory system. Silicon is found concentrated within the arteries, where it helps make the inner lining of arterial tissue less permeable. Together they help blood vessels relax and open to ensure healthy blood flow while protecting the structure of blood vessel tissue for health and function.

Arginine has been clinically studied to significantly raise nitric oxide levels, generating more blood flow to working muscles and supporting overall cardiovascular health. With continued use, Arginine Complex can help build nitric oxide levels over time, offering a long-term solution for cardiovascular maintenance.

FAQ

How does L-arginine work in the body?
L-arginine is an amino acid involved in several important metabolic processes. It supports protein synthesis and serves as the primary building block the body uses to produce nitric oxide, a molecule that supports healthy circulation.
How does L-arginine support nitric oxide production?
L-arginine is the direct precursor to nitric oxide. Through a natural enzymatic process, the body converts L-arginine into nitric oxide to help support healthy blood flow, oxygen delivery, and exercise performance.
What is nitric oxide, and why is it important?
Nitric oxide is a molecule naturally produced by the body that helps blood vessels relax and widen, supporting healthy circulation. It also helps deliver oxygen and nutrients to working muscles and other tissues, making it important for cardiovascular health and physical performance.
What makes Swanson Arginine Complex unique?
Swanson Arginine Complex delivers 750 mg of Nitrosigine®, a patented complex of arginine, silicate, and inositol. Unlike standard L-arginine supplements, Nitrosigine is designed to provide sustained nitric oxide support and has been clinically studied for its role in supporting healthy circulation, exercise performance, and cognitive function.
Is Swanson Arginine Complex suitable for special diets?
Yes. Swanson Arginine Complex is suitable for vegan and vegetarian lifestyles and is made with non-GMO ingredients. This product is not formulated or certified to be dairy-free or gluten-free, so individuals with dietary sensitivities should review the ingredient list before use.
