Why citrulline instead of just arginine?
When taken orally, a significant portion of arginine is broken down before reaching circulation. Citrulline bypasses much of this process, since the body converts it to arginine in the kidneys, often resulting in a more sustained elevation in circulating arginine levels.
What does "HCl" mean?
HCl (hydrochloride) refers to the salt form of citrulline used in supplements, chosen for stability and solubility.
Citrulline HCl's role in SodaFil
Alongside L-Citrulline Malate, this ingredient is included to extend the circulatory benefits of the formula beyond the initial arginine boost, supporting stamina later into the day or a workout. See our L-Citrulline Malate article for the complementary piece.
Safety considerations
Citrulline is generally well tolerated, but as with other circulation-affecting ingredients, consult a doctor if you're on blood pressure medication or manage a cardiovascular condition.
