What it is
The body converts L-Citrulline into L-arginine, a compound involved in normal blood vessel function — which is why it's a frequent pick for circulation-minded formulas. It works conceptually alongside the formula's other blood-flow-associated ingredients.
Where it sits in the formula
L-Citrulline is one of eight ingredients named openly on the HoneyFil label — no vague "proprietary blend" wording anywhere. As with the rest of the formula, we don't attach a specific milligram figure to it, since that number isn't part of the publicly available material we were able to review; your bottle's Supplement Facts panel remains the accurate source.
