Genius L-Arginine for Enhanced Blood Flow and Athletic Performance

L-arginine is an amino acid that helps the body produce nitric oxide, a compound that relaxes and widens blood vessels to support healthy circulation. Because of this, it’s often used to promote better blood flow, endurance, and muscle performance. Genius L-Arginine combines pure fermented L-arginine with AstraGin™ to enhance absorption, making it useful for supporting heart health, exercise performance, and overall vascular function.*

Yes, arginine can be beneficial for heart health because it supports the body’s natural production of nitric oxide, which helps blood vessels relax and improves circulation. Better blood flow may contribute to healthier blood pressure levels and overall cardiovascular function. Genius L-Arginine combines this heart-supporting amino acid with AstraGin™ to enhance absorption and maximize its nitric oxide benefits for vascular wellness.*

For women, L-arginine helps support healthy circulation by promoting nitric oxide production, which widens blood vessels and improves blood flow. This can aid overall energy, endurance, and heart wellness. Some women also use L-arginine to support reproductive health and exercise performance. Genius L-Arginine enhances these benefits with AstraGin™, which helps the body absorb L-arginine more efficiently for better results.*

L-arginine can be taken daily to help maintain consistent nitric oxide levels and support healthy circulation.

As with any supplement, it’s best to follow the recommended serving and consult a healthcare professional if you have medical conditions or take medication.*

L-arginine may help support healthy blood pressure by increasing nitric oxide production, which relaxes and widens blood vessels to improve circulation. This natural vasodilation can make it easier for the heart to pump blood efficiently. Genius L-Arginine combines pure fermented L-arginine with absorption-enhancing compounds, helping the body use it effectively for cardiovascular and vascular health.*

L-arginine does not typically cause constipation, but digestive responses can vary from person to person. Some users may experience mild stomach upset if taken on an empty stomach or in high doses. Genius L-Arginine uses a fermented form of L-arginine to improve nutrient absorption and support comfortable digestion, helping reduce the chance of gastrointestinal discomfort.*

You should avoid taking L-arginine if you have certain health conditions such as low blood pressure, heart or kidney issues, or if you’re taking medications like nitrates or erectile dysfunction drugs, which also affect blood flow. These combinations can cause unwanted drops in blood pressure. While Genius L-Arginine is formulated for general cardiovascular support, it’s best to consult a healthcare provider before use if you have any medical conditions or are on prescription medication.*

L-arginine begins working soon after it’s absorbed, as the body converts it into nitric oxide to support better blood flow. Most people may notice improved circulation or performance benefits within 30 to 60 minutes of taking it, especially before exercising. With consistent daily use, Genius L-Arginine helps maintain nitric oxide levels over time, supporting long-term cardiovascular and endurance benefits.*

L-arginine is not a stimulant, so it typically will not keep you awake. Its main function is to support nitric oxide production, which helps improve blood flow and circulation rather than directly affecting energy or sleep. Some people prefer taking it earlier in the day or before workouts to align with its performance benefits. Genius L-Arginine uses a clean, caffeine-free formula, making it suitable for both daytime and evening use without disrupting sleep.*
