About the Brand
Sundance Ultra L-Arginine is manufactured by Sundance Vitamins. It was founded in the USA by a father and son who shared a passion for health and wellness. Sundance Vitamins says that its mission is to empower customers to feel their best through accessible and effective health solutions.
They also claim to focus on creating supplements that address various health needs. All products are said to be made with non-GMO, gluten-free formulations.
However, their dietary supplements have not undergone evaluation by clinical trials or independent labs. This means that the effectiveness of their products is not guaranteed and may depend on individual results.
How Does Sundance Ultra L-Arginine Work?
Sundance Ultra L-Arginine claims to support cardiovascular health and enhance circulation by providing the body with L-arginine in a quick-release capsule form.
L-arginine is an amino acid that gets converted into nitric oxide. This increased nitric oxide level leads to the relaxation of smooth muscle cells within blood vessels, which can promote blood circulation and support cardiovascular function.
A study published in the Journal of Nutrition found that L-Arginine enhances endothelial nitric oxide production, leading to improved blood vessel function.
Healthy blood vessels rely on good endothelial function, which helps regulate blood flow and blood pressure. When this function is impaired, it can lead to poor blood flow and increase the risk of heart problems.
While these claims are promising, the effectiveness of the product may depend on individual health and lifestyle. You may also need to use the supplement with a balanced diet and regular exercise to get the best result.
Sundance Ultra L-Arginine Ingredients – Are they Safe and Effective?

L-arginine (Free form)
L-arginine, in its free form, is a non-synthetic, bioavailable form of the amino acid L-arginine that is not bound to any other substance. This may allow for easier absorption and utilization by the body.
As documented in our WowMD L-Arginine Plus Review (another supplement containing this ingredient), L-arginine boosts nitric oxide production which can help to expand blood vessels and improve blood flow and oxygen delivery to the muscles.
In addition, a clinical trial with its findings in the Journal of the American College of Cardiology suggests that L-arginine supplementation can enhance endothelial function, which is critical for maintaining vascular health.
Natalia Kurhaluk of the Department of Biology, Institute of Biology and Earth Sciences, Pomeranian University in S?upsk, Arciszewski, says in her research, Arginine supplementation may be a potential strategy in the prevention of cardiovascular diseases.
