L-Citrulline: The Circulation Ingredient

If you've looked at any circulation or performance-focused supplement, you've probably seen L-Citrulline near the top of the label. It's one of the most common amino acids in this category, and for good reason.

L-Citrulline supports the body's natural nitric oxide production, a compound that helps blood vessels relax and open, supporting healthy blood flow throughout the body.

In HorseFil, it anchors the circulation side of the formula, working alongside energy-focused ingredients like L-Carnitine and traditional botanicals like Panax Ginseng.

Like any amino acid, its effects build with consistent use rather than a single dose — which is why HorseFil is designed as a daily gummy, not an occasional pick-me-up.
