Citrulline is an amino acid many lifters mix into a pre-training drink, alone or with creatine. Choose OstroVit Citrulline 210g, an L-citrulline powder with a 3g serving in Natural and five flavours, or Trec Nutrition Citrulline Synergy 240g, a citrulline malate and L-citrulline blend in Mango or Watermelon Apple.
L-citrulline is the amino acid on its own. Citrulline malate binds it to malic acid, so part of every gram is malate. In a 2:1 malate, 6 g provides about 4 g of citrulline. When you compare products, look for the amount of pure L-citrulline on the label:
Both labels direct a serving before training: OstroVit says about 30 minutes before. Neither contains caffeine, so they suit evening sessions. Natural is the best choice for a home-made stack, because it will not clash with other flavours. Citrulline attracts moisture and can clump, so keep the lid tight and store the tub somewhere dry. Citrulline has no authorised health claim, so we describe it by ingredient and dose. If you stack it with creatine, note that creatine's authorised performance claim applies at 3 g a day.
Compare the arginine-based alternatives in AAKG & Arginine, or browse premixed formulas in Pre-Workout and the wider Pump & Nitric Oxide range.
It depends on the product: OstroVit Citrulline uses a 3 g serving, and a 6 g serving of Trec Citrulline Synergy provides 3708 mg of L-citrulline. Do not exceed the serving on the label.
Citrulline absorbs moisture from the air, so it clumps if the lid is left loose or the tub is stored somewhere damp. Break the clumps up with a dry spoon and keep the lid tightly closed.
Choose Natural if you mix your own stack and want no flavour clash. Choose a flavoured version, such as OstroVit Orange or Trec Watermelon Apple, if you drink it on its own.
No. Both citrulline powders here are stimulant-free, so you can use them before late training sessions or alongside a separate caffeinated pre-workout.
Follow the label: OstroVit directs a serving on training days, before exercise. There is no need to exceed the daily serving shown on either product.
