What is L-Arginine?

L-Arginine is a commonly occurring amino acid which can be found in the diet in red meat, fish and dairy products. It is also found naturally in the human body where it contributes to a number of vital functions. Amino acids are the building blocks that link together to form proteins.

L-Arginine plays a vital role in the synthesis of nitric oxide. Nitric oxide causes blood vessels to open wider leading to an improved blood flow. This has led to the supplement to grow in popularity amongst men.

What is in each capsule?

Each Healthspan tablet contains 750mg of free base L-Arginine. The more easily absorbed free base L-Arginine form provides much higher levels per gram compared to standard L-Arginine hydrochloride.
