What Is L-Arginine?
L-Arginine is a semi-essential amino acid, meaning the body can produce some on its own but benefits from additional dietary intake.
Its Role In The Vigor Boost Formula
It's the formula's core circulation ingredient, supporting the body's nitric oxide production pathway.
Traditional Use & What The Research Says
Nitric oxide is well studied for its role in vascular relaxation, and L-Arginine is its most direct dietary precursor.
Worth knowing: Its effect on circulation is generally described as supportive of existing healthy vascular function, not a treatment for any diagnosed condition.
This describes general research on L-Arginine itself, not the finished Vigor Boost product, which hasn't been the subject of its own clinical trial. See the full ingredients list or the formula overview for more.
