L-Citrulline is one of the most studied amino acids for circulation support — and a key ingredient in Horsefil. Here's why it matters.
What Is L-Citrulline?
L-Citrulline is an amino acid the body converts into nitric oxide, supporting healthy blood flow already within normal levels.
Why Healthy Circulation Matters
Good circulation plays a role in delivering oxygen and nutrients throughout the body, which can contribute to energy levels and physical performance.
Widely Studied in Exercise Science
L-Citrulline has been widely studied in the context of exercise performance and cardiovascular health.
L-Citrulline in Horsefil
Horsefil includes L-Citrulline as a core circulation-support ingredient — see the ingredients page and the current Horsefil discount on the Horsefil official website.
L-Citrulline supports healthy circulation and is not a treatment for any condition. Consult your doctor before use, especially if you take blood pressure medication.
