L-Citrulline is an amino acid that your body converts into another amino acid called L-Arginine. L-Arginine then boosts nitric oxide, which relaxes blood vessels and improves blood flow. That's the basis for most of L-Citrulline's claimed benefits. The research is mixed. The strongest evidence is for getting a few extra reps during weight training and making workouts feel easier. Effects on endurance running or body composition are generally not there. You'll see two forms: plain L-Citrulline and Citrulline Malate (L-Citrulline bonded to malic acid). The ratio on Citrulline Malate labels matters for comparing doses — a "2:1" product is about two-thirds L-Citrulline by weight, and a "1:1" product is about half. So 8g of 2:1 Citrulline Malate is really about 5g of L-Citrulline. Typical doses in research are 3–8g per day. Products below are ranked by cost at your chosen daily dose.

This is the current ranking surface for L-Citrulline. It recalculates cost per month from product price, Supplement Facts active amount, servings per container, and the dose you enter above.
55 active products have enough price and label data to calculate cost before display filters; 52 rows are currently shown in the ranked table. The current review floor for this category is 25+ reviews before any large-category and duplicate/bulk filtering.
At 6 g/day, visible products range from $2.88-$1138.50/mo with a $7.35/mo median midpoint and a 395.3x low-to-high spread.
Check whether the label says L-Citrulline or Citrulline Malate, and whether the malate ratio is stated. Labels reviewed for this update included pure citrulline powders, citrulline malate products, capsules, and pre-workout-style formulas.
Powder format, dose size, and form drive the price. A 6 g/day comparison dose makes capsules less efficient, while citrulline malate labels can look larger because the malate portion is included in the total compound weight.
Do not treat 6 g of citrulline malate as 6 g of pure L-Citrulline unless the label states the citrulline content. Also avoid counting an entire pump or pre-workout blend as citrulline when the ingredient is not separately quantified.
L-Citrulline has moderate evidence for some resistance-training performance outcomes and lower perceived exertion, with less consistent endurance results. TrueServing compares labeled cost at 6 g/day and does not convert unstated citrulline-malate ratios.
