How Does Thorne L-Arginine Plus Work?
Thorne L-Arginine Plus supports your body’s natural production of nitric oxide, which helps relax and widen blood vessels. This process improves blood flow, allowing more oxygen and nutrients to reach your heart, muscles, and other tissues. Better circulation can support healthy blood pressure, improve physical performance, and aid recovery after activity.
The supplement also provides antioxidants to protect cells from damage caused by oxidative stress. These antioxidants help maintain vascular health and promote well-being, especially as we age. Research published in the Molecular Aspect of Medicine highlights the role of nitric oxide in improving cardiovascular health.
Thorne L-Arginine Plus Key Ingredients – Are They Safe & Effective?
Here are some claimed key ingredients
L-Arginine
L-arginine is a semi-essential amino acid that plays a key role in producing nitric oxide, which relaxes blood vessels and improves circulation. As documented in our WOWMD L-Arginine Plus Review(another supplement containing this ingredient), this helps support healthy blood pressure, heart health, and physical performance.
Also, a study in the Journal of Nutrition highlights L-Arginine’s role in promoting vascular health and enhancing blood flow, particularly in individuals with cardiovascular concerns.
Green Tea Phytosome
Green Tea Phytosome is a decaffeinated extract that combines green tea with phospholipids to improve absorption. Known for its antioxidant properties, it helps reduce oxidative stress and supports heart health.
As documented in our KetoFuse Review (another supplement containing this ingredient), green tea helps boost energy for higher activity and physical performance. Also, research published in Current Medicinal Chemistry explains how green tea polyphenols benefit cardiovascular health by protecting blood vessels and reducing inflammation.
R-Lipoic Acid
R-lipoic acid is an antioxidant that helps reduce cell oxidative damage and supports energy production. It has been shown to improve vascular function and protect against age-related decline. A review in Oxidative Medicine and Cellular Longevity discusses its potential in managing oxidative stress and promoting vascular health.
Trans-Resveratrol
Trans-resveratrol, a compound found in red wine and certain plants, is known for improving vascular health and reducing inflammation. It supports nitric oxide production and enhances blood flow. A study in the Journal of Update in Cardiovascular Medicine reviews its effectiveness in promoting cardiovascular health and managing oxidative damage.
Vitamin C
Vitamin C is a powerful antioxidant that protects cells from damage and supports the immune system. It also helps maintain blood vessel health and elasticity. Research published in the Antioxidant & Redox Signaling journal highlights how vitamin C supplementation improves endothelial function, benefiting cardiovascular health.
