L-Citrulline is a headline ingredient in SteelPower. Here's why this amino acid matters for circulation and performance.
What Is L-Citrulline?
L-Citrulline is an amino acid that the body converts to L-arginine and then into nitric oxide, a molecule that helps relax and widen blood vessels (PubMed).
Nitric Oxide & Circulation
By supporting nitric oxide production, L-Citrulline supports healthy blood flow — which is central to stamina and performance.
Endurance & Recovery
Better circulation also supports exercise performance and recovery, part of an active lifestyle.
L-Citrulline in Steel Power
In Steel Power, L-Citrulline works alongside Pine Bark Extract and Panax Ginseng for circulation support — see the ingredients page and the current Steel Power discount on the Steel Power official website.
L-Citrulline supports healthy circulation and is not a treatment for any condition. Consult your doctor before use if you take medication for blood pressure or heart conditions.
